Bromine
A halogen with the atomic symbol Br, atomic number 36, and atomic weight 79.904. It is a volatile reddish-brown liquid that gives off suffocating vapors, is corrosive to the skin, and may cause severe gastroenteritis if ingested.
Hydrocarbons, Halogenated
Halogenation
Covalent attachment of HALOGENS to other compounds.
Light-Curing of Dental Adhesives
The hardening or polymerization of bonding agents (DENTAL CEMENTS) via exposure to light.

Evidence that halogenated furanones from Delisea pulchra inhibit acylated homoserine lactone (AHL)-mediated gene expression by displacing the AHL signal from its receptor protein. (1/259)

Acylated homoserine lactone (AHL)-mediated gene expression controls phenotypes involved in colonization, often specifically of higher organisms, in both marine and terrestrial environments. The marine red alga Delisea pulchra produces halogenated furanones which resemble AHLs structurally and show inhibitory activity at ecologically realistic concentrations in AHL bioassays. Evidence is presented that halogenated furanones displace tritiated OHHL [N-3-(oxohexanoyl)-L-homoserine lactone] from Escherichia coli cells overproducing LuxR with potencies corresponding to their respective inhibitory activities in an AHL-regulated bioluminescence assay, indicating that this is the mechanism by which furanones inhibit AHL-dependent phenotypes. Alternative mechanisms for this phenomenon are also addressed. General metabolic disruption was assessed with two-dimensional PAGE, revealing limited non-AHL-related effects. A direct chemical interaction between the algal compounds and AHLs, as monitored by 1H NMR spectroscopy, was shown not to occur in vitro. These results support the contention that furanones, at the concentrations produced by the alga, can control bacterial colonization of surfaces by specifically interfering with AHL-mediated gene expression at the level of the LuxR protein.  (+info)

Degradation of 1,2-dibromoethane by Mycobacterium sp. strain GP1. (2/259)

The newly isolated bacterial strain GP1 can utilize 1, 2-dibromoethane as the sole carbon and energy source. On the basis of 16S rRNA gene sequence analysis, the organism was identified as a member of the subgroup which contains the fast-growing mycobacteria. The first step in 1,2-dibromoethane metabolism is catalyzed by a hydrolytic haloalkane dehalogenase. The resulting 2-bromoethanol is rapidly converted to ethylene oxide by a haloalcohol dehalogenase, in this way preventing the accumulation of 2-bromoethanol and 2-bromoacetaldehyde as toxic intermediates. Ethylene oxide can serve as a growth substrate for strain GP1, but the pathway(s) by which it is further metabolized is still unclear. Strain GP1 can also utilize 1-chloropropane, 1-bromopropane, 2-bromoethanol, and 2-chloroethanol as growth substrates. 2-Chloroethanol and 2-bromoethanol are metabolized via ethylene oxide, which for both haloalcohols is a novel way to remove the halide without going through the corresponding acetaldehyde intermediate. The haloalkane dehalogenase gene was cloned and sequenced. The dehalogenase (DhaAf) encoded by this gene is identical to the haloalkane dehalogenase (DhaA) of Rhodococcus rhodochrous NCIMB 13064, except for three amino acid substitutions and a 14-amino-acid extension at the C terminus. Alignments of the complete dehalogenase gene region of strain GP1 with DNA sequences in different databases showed that a large part of a dhaA gene region, which is also present in R. rhodochrous NCIMB 13064, was fused to a fragment of a haloalcohol dehalogenase gene that was identical to the last 42 nucleotides of the hheB gene found in Corynebacterium sp. strain N-1074.  (+info)

Renal angiotensin I-converting enzyme as a mixture of sialo- and asialo-enzyme, and a rapid purification method. (3/259)

Angiotensin I-converting enzyme [EC 3.4.15.1] was rapidly and highly purified from a particulate fraction of hog kidney cortex with 13% yield. The procedure, which was rapid, included fractionation on DEAE-cellulose and calcium phosphate gel, chromatographies on DEAE-Sephadex A-50 and hydroxylapatite columns, and gel filtration on a Sephadex G-200 column. The purified enzyme preparation gave two protein bands on standard disc gel electrophoresis, but showed a single protein component on the gel after treatment with neuraminidase [EC 3.2.1.18]. The data strongly suggest that the purified enzyme preparation was a mixture of sialo- and asialo-enzyme. Sialic acid residues apparently do not contribute to the catalytic activity of the enzyme. The enzyme was activated more by chloride ions than by other halide ions tested, using Bz-Gly-Gly-Gly as a substrate. The dissociation constant for chloride ions was determined to be 2.2 mM. Chloride did not protect the enzyme against heat or low pH. The enzyme was resistant to inactivation by trypsin [EC 3.4.21.4] and chymotrypsin [EC 3.4.21.1].  (+info)

A possible effect of different light sources on pregnancy rates following gamete intra-fallopian transfer. (4/259)

A retrospective study of 34 sequential gamete intra-Fallopian transfer (GIFT) procedures suggested a significant effect on pregnancy rates associated with the different laparoscopic light sources, with a pregnancy rate of 50% in 22 cycles using a halogen light source and 9% in 12 cycles using a xenon light source. Other explanatory variables were explored, but none was to have a significant effect on the pregnancy rate. Further investigation revealed that the xenon light source emitted more ultraviolet light than the conventional halogen light source--suggesting a possible detrimental effect of ultraviolet light on the gametes in the GIFT procedure.  (+info)

Induction and prevention of micronuclei and chromosomal aberrations in cultured human lymphocytes exposed to the light of halogen tungsten lamps. (5/259)

Previous studies have shown that the light emitted by halogen tungsten lamps contains UV radiation in the UV-A, UV-B and UV-C regions, induces mutations and irreparable DNA damage in bacteria, enhances the frequency of micronuclei in cultured human lymphocytes and is potently carcinogenic to the skin of hairless mice. The present study showed that the light emitted by an uncovered, traditional halogen lamp induces a significant, dose-related and time-related increase not only in micronuclei but also in chromosome-type aberrations, such as breaks, and even more in chromatid-type aberrations, such as isochromatid breaks, exchanges and isochromatid/chromatid interchanges, all including gaps or not, in cultured human lymphocytes. All these genotoxic effects were completely prevented by shielding the same lamp with a silica glass cover, blocking UV radiation. A new model of halogen lamp, having the quartz bulb treated in order to reduce the output of UV radiation, was considerably less genotoxic than the uncovered halogen lamp, yet induction of chromosomal alterations was observed at high illuminance levels.  (+info)

DL-2-Haloacid dehalogenase from Pseudomonas sp. 113 is a new class of dehalogenase catalyzing hydrolytic dehalogenation not involving enzyme-substrate ester intermediate. (6/259)

DL-2-Haloacid dehalogenase from Pseudomonas sp. 113 (DL-DEX 113) catalyzes the hydrolytic dehalogenation of D- and L-2-haloalkanoic acids, producing the corresponding L- and D-2-hydroxyalkanoic acids, respectively. Every halidohydrolase studied so far (L-2-haloacid dehalogenase, haloalkane dehalogenase, and 4-chlorobenzoyl-CoA dehalogenase) has an active site carboxylate group that attacks the substrate carbon atom bound to the halogen atom, leading to the formation of an ester intermediate. This is subsequently hydrolyzed, resulting in the incorporation of an oxygen atom of the solvent water molecule into the carboxylate group of the enzyme. In the present study, we analyzed the reaction mechanism of DL-DEX 113. When a single turnover reaction of DL-DEX 113 was carried out with a large excess of the enzyme in H(2)(18)O with a 10 times smaller amount of the substrate, either D- or L-2-chloropropionate, the major product was found to be (18)O-labeled lactate by ionspray mass spectrometry. After a multiple turnover reaction in H(2)(18)O, the enzyme was digested with trypsin or lysyl endopeptidase, and the molecular masses of the peptide fragments were measured with an ionspray mass spectrometer. No peptide fragments contained (18)O. These results indicate that the H(2)(18)O of the solvent directly attacks the alpha-carbon of 2-haloalkanoic acid to displace the halogen atom. This is the first example of an enzymatic hydrolytic dehalogenation that proceeds without producing an ester intermediate.  (+info)

Mcm2, but not RPA, is a component of the mammalian early G1-phase prereplication complex. (7/259)

Previous experiments in Xenopus egg extracts identified what appeared to be two independently assembled prereplication complexes (pre-RCs) for DNA replication: the stepwise assembly of ORC, Cdc6, and Mcm onto chromatin, and the FFA-1-mediated recruitment of RPA into foci on chromatin. We have investigated whether both of these pre-RCs can be detected in Chinese hamster ovary (CHO) cells. Early- and late-replicating chromosomal domains were pulse-labeled with halogenated nucleotides and prelabeled cells were synchronized at various times during the following G1-phase. The recruitment of Mcm2 and RPA to these domains was examined in relation to the formation of a nuclear envelope, specification of the dihydrofolate reductase (DHFR) replication origin and entry into S-phase. Mcm2 was loaded gradually and cumulatively onto both early- and late-replicating chromatin from late telophase throughout G1-phase. During S-phase, detectable Mcm2 was rapidly excluded from PCNA-containing active replication forks. By contrast, detergent-resistant RPA foci were undetectable until the onset of S-phase, when RPA joined only the earliest-firing replicons. During S-phase, RPA was present with PCNA specifically at active replication forks. Together, our data are consistent with a role for Mcm proteins, but not RPA, in the formation of mammalian pre-RCs during early G1-phase.  (+info)

Effect of Tn10/Tn5 transposons on the survival and mutation frequency of halogen light-irradiated AB1157 Escherichia coli K-12. (8/259)

We show here that the Tn10/Tn5 transposon when inserted into the chromosome of strain AB1157 makes the bacteria more sensitive to and less mutable by halogen light irradiation. These effects are most probably caused by depletion of UmuD and UmuC proteins since: (i) transformation of the transposon-bearing bacteria with plasmids harbouring umuD'C (or umuDC) leads to recovery of the original survival and mutation frequencies; (ii) insertion of Tn10/Tn5 into chromosomal DNA has no effect on the level of mutation induced by ethyl methane-sulphonate treatment, a mutagen whose activity is umuDC-independent; (iii) the decline in survival is in about the same range for Tn10-bearing bacteria as for bacteria with deleted umuDC. However, whereas transformation of bacteria deleted in umuDC with plasmids carrying umuD'C/umuDC leads to full recovery of halogen light-induced mutability, recovery of survival is poor. This suggests that the mechanisms leading to umuDC-dependent mutagenesis and umuDC-dependent protection of cell survival are different. None of these effects occurs in bacteria bearing the Tn9 transposon in their DNA.  (+info)

Review of a halogen lamp - storiestrending.comReview of a halogen lamp - storiestrending.com
Halogen lamp is an incandescent lamp with an advanced design and is also called a tungsten or quartz halogen lamp. The filament of the light bulb consists of ductile tungsten, while the light bulb itself consists of quartz, aluminum silicate or silica. The gas contained in the light bulb has a higher pressure than an ordinary light bulb.. WORK OF THE HALOGEN LAMP The halogen lamp contains halogen gas in the lamp. This gas prevents the bulb from turning black, unlike conventional ones, and also lowers the thinning of the tungsten filament. As a result, the filament can be heated to a much higher temperature while the life of the light bulb is also significantly improved. There are many elements called halogen but not all are used in the design of such lamps. Iodine and bromine are used in the halogen lamps.. Chemistry involved in a halogen lamp includeis the chemical combination of the vaporized tungsten atoms with the halogen gas which is then re-deposited on the tungsten filament. This prevents ...

Introduction. Victor Leung 7C (10) Experiment Date: 28TH September, 2006. EXP1 - Hydrolysing Organic Halogen Compounds Aim: The purpose of this experiment is to find out how the rate of the hydrolysis of an organic halogen compound depends on (1) the identity of the halogen atom (2) the nature of the CH skeleton. Principle: The hydrolysis of haloalkanes is an example of nucleophilic substitution in which the carbon halogen bond is replaced with a hydroxyl group. Water molecule is the nucleophile of the reaction while the halide ion departs as the leaving group. The reaction occurs faster with alcohol acting as a common solvent. The ease of leaving of halide ions increase in as the atom becomes bigger, and the bonding length longer. Method: The experiment made use of the product of hydrolysis - halide ions. The halide ions formed could be detected by AgNO3 which forms precipitation. The length of time required is inversely proportional to the rate of reaction. By observing the changes in the test ...

Halide - WikipediaHalide - Wikipedia
A halide is a binary phase, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound. The alkali metals combine directly with halogens under appropriate conditions forming halides of the general formula, MX (X = F, Cl, Br or I). Many salts are halides; the hal- syllable in halide and halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. A halide ion is a halogen atom bearing a negative charge. The halide anions are fluoride (F−), chloride (Cl−), bromide (Br−), iodide (I−) and astatide (At−). Such ions are present in all ionic halide salts. Halide minerals contain halides. All these halides are colourless, high melting crystalline solids having high negative enthalpies of formation. ...

METHYLENE IODIDE (DIIODOMETHANE)METHYLENE IODIDE (DIIODOMETHANE)
Halogenoalkanes, also known as haloalkanes or alkyl halides, are organic compounds in which one or more hydrogen atoms in an alkane have been replaced by halogen atoms, fluorine, chlorine, bromine or iodine. In carbon-halogen bond, halogens have significantly greater electronegativities than carbon except iodine. In result, this functional group is polarized so that the carbon is electrophilic and the halogen is nucleophilic. Halogenoalkanes are can be classified depending on the halogen atom position on the chain of carbon atoms. The carbon which is attached with the halogen atom is linked up with only one other alkyl group in primary halogenoalkanes, whereas directly linked up with two and three other alkyl groups in secondary halogenoalkanes and tertiary halogenoalkanes respectively. In some case, primary halogenoalkanes are counted even though there are no alkyl groups attached to the carbon with the halogen on it. Three characteristics provide important influences on the chemical behavior ...

Dithienophenazine derivatives are molecules recently synthesized from different groups in attempt to apply them to inorganic electronics. Our group recently synthesized five different derivatives with dithieno[3,2-a:2′,3′-c]phenazine (DTPhz) with equal substituents at 9 and 10 position (H, F, Cl, Br) or pyrido[2,3-b]dithieno[3,2-f:2′,3′-h]quinoxaline (8N-DTPhz). These molecules are very similar in their electronic properties because they have similar band gaps and HOMO levels, but different dipole moments between the halogen derivatives and the non-halogen derivatives. Being very similar as donors make them very good examples to study halogen bonding in donor-acceptor co-crystals with a fully perfluorinated acceptor such as trimeric perfluoro-ortho-phenylene mercury (TPPM). Halogen bonding was important in these co-crystals, since only the donors with halogen substituents lead to co-crystals with mixed donor-acceptor stacks. Unsubstituted DTPhz do not gave co-crystals, and 8N-DTPhz gave ...

The synthesis and anion binding properties of novel halogen-bonding (XB) bis-iodotriazole-pyridinium-containing acyclic and {[}2]catenane anion host systems are described. The XB acyclic receptor displays selectivity for acetate over halides with enhanced anion recognition properties compared to the analogous hydrogen-bonding (HB) acyclic receptor. A reversal in halide selectivity is observed in the XB {[}2]catenane, in comparison to the acyclic XB receptor, due to the interlocked hosts unique three-dimensional binding cavity, and no binding is observed for oxoanions. Notable halide anion association constant values determined for the {[}2]catenane in competitive organicaqueous solvent mixtures demonstrate considerable enhancement of anion recognition as compared to the HB catenane analogue. X-ray crystallographic analysis of a series of halide catenane complexes reveal strong XB interactions in the solid state.

E1 Elimination Reactions - Chemistry LibreTextsE1 Elimination Reactions - Chemistry LibreTexts
Since the SN1 and E1 reactions proceed via the same carbocation intermediate, the product ratios are difficult to control and both substitution and elimination usually take place.. Having discussed the many factors that influence nucleophilic substitution and elimination reactions of alkyl halides, we must now consider the practical problem of predicting the most likely outcome when a given alkyl halide is reacted with a given nucleophile. As we noted earlier, several variables must be considered, the most important being the structure of the alkyl group and the nature of the nucleophilic reactant. The nature of the halogen substituent on the alkyl halide is usually not very significant if it is Cl, Br or I. In cases where both SN2 and E2 reactions compete, chlorides generally give more elimination than do iodides, since the greater electronegativity of chlorine increases the acidity of beta-hydrogens. Indeed, although alkyl fluorides are relatively unreactive, when reactions with basic ...

Dimers of lithium formamidinate, CH(NH)2Li, and halogenated formamidines, HN=CHNHX, (X=Cl, Br, or I) are used as model systems to investigate simultaneous N-X···N and N-Li···N interactions, in tandem with orthogonal Li···X interactions. Geometry optimizations and energy calculations for the dimers are examined with the MP2 method and the M06-2X hybrid functional and the aug-cc-pVTZ basis set (the aug-cc-pVTZ-PP basis set is used for the iodine atom). Both methods predict the formation of a planar structure of C2v symmetry, regardless of the identity of the halogen atom. In this structure, the identities of the constituent monomers are essentially lost. Accordingly, the N-X···N interactions emerge as a rather symmetric quasi-linear N···X···N, where the covalent N-X bond in the halogenated formamidine is replaced by a partly covalent N···X interaction. Formation of the C2v structure is also driven by a fairly linear N···Li···N interaction parallel to the N···X···N

Porous silicon layers were fabricated by electrochemical etching of boron-doped p+-type silicon wafers (resistivity 0.01 to 0.05 Ω · cm; orientation ,100,). The composition of the solution was 1:2 hydrofluoric (HF) (48 wt.%):ethanol (98 wt.%). The wafers were galvanostatically etched under illumination from a 100-W halogen lamp. The applied etching density current was 80 mA · cm-2 for 20 s to grow layers around 75% porosity and 750 nm of thickness.. The deposition of Cu nanoparticles over p+-type crystalline Si and nanoPS layers was carried out by immersing the substrates in CuSO4 (50 mM) and H2SO4 (1 mM) aqueous solutions at room temperature during different times. H2SO4 is used to stabilize the pH. The deposition was activated by turning on the 100-W halogen lamp during the appropriate time. Once the deposition is finished, the samples are washed and rinsed twice in water and twice in ethanol and subsequently dried with N2.. Field emission scanning electron microscopy (FESEM) images were ...

Coordinative halogen bonds have recently gained interest for the assembly of supramolecular capsules. Ion mobility-mass spectrometry and theoretical calculations now reveal the well-defined gas-phase structures of dimeric and hexameric [N⋯I+⋯N] halogen-bonded capsules with counterions located inside their cavities as guests. The solution reactivity of the large hexameric capsule shows the intriguing solvent-dependent equilibrium between the hexamer and an unprecedented pentameric [N⋯I+⋯N] halogen-bonded capsule, when the solvent is changed from chloroform to dichloromethane. The intrinsic flexibility of the cavitands enables this novel structure to adopt a pseudo-trigonal bipyramidal geometry with nine [N⋯I+⋯N] bonds along the edges and two pyridine binding sites uncomplexed. ...

Halogens are a group of highly reactive elements including fluorine, chlorine, bromine, iodine and astatine. When products containing halogens are burned, they produce very dangerous gasses. Public awareness of these dangers began after several tragic fires claimed the lives of victims who inhaled deadly halogenated fumes.. Several fires, including those at the Beverley Hills Supper Club, Londons Kings Cross Underground Station and Germanys Düsseldorf Airport, have lead to important changes that significantly limit where cables containing halogens may be used. Many organizations, local authorities and governments have undertaken broad initiatives to eliminate the production of halogenated material. In Asia, the United Kingdom and many European communities, the use of wire and cable containing halogens is highly regulated, and in some areas completely prohibited.. ...

Group 7, the halogens - Revision Cards in A Level and IB ChemistryGroup 7, the halogens - Revision Cards in A Level and IB Chemistry
Chlorine is a poisonous gas and was used in the First World War. Chlorine is soluble in water and in this form has become an essential part of our life because it treats water so its good for drinking and is used in swimming pools.. The reaction with water Chlorine reacts with water in a reversible reaction to form chloric acid (HClO) and hydrochloric acid. In this reaction, the oxidation number of one of the chlorine atoms increases from a 0 to a +1. But, another Cl loses and becomes -1 and during this sort of redox reaction, where the same element decreases and increases, there is a name given to it. Its called - disproportionation.. This reaction takes place when chlorine is used to purify water for drinking and swimming pools; it prevents life threatening diseases that are in the water. It does this because Chloric acid oxidises bacteria, which kills it; its an oxiding agent! Chloric acid is also bleach.. Other halogens react similarly, however it is much more slowly as we go down the ...

Pseudohalogen - WikipediaPseudohalogen - Wikipedia
The pseudohalogens are polyatomic analogues of halogens, whose chemistry, resembling that of the true halogens, allows them to substitute for halogens in several classes of chemical compounds. Pseudohalogens occur in pseudohalogen molecules, inorganic molecules of the general forms Ps-Ps or Ps-X (where Ps is a pseudohalogen group), such as cyanogen; pseudohalide anions, such as cyanide ion; inorganic acids, such as hydrogen cyanide; as ligands in coordination complexes, such as ferricyanide; and as functional groups in organic molecules, such as the nitrile group. Well-known pseudohalogen functional groups include cyanide, cyanate, thiocyanate, and azide. Many pseudohalogens are known by specialized common names according to where they occur in a compound. Well-known ones include (the true halogen chlorine is listed for comparison): Examples of symmetrical pseudohalogens (Ps-Ps) include cyanogen (CN)2, thiocyanogen (SCN)2, selenorhodane (SeCN)2, azidodithiocarbonate (N3CS2)2.

Experimental parameters were optimized by fractional factorial design and response surface methodology. Fractional factorial design was employed in screening experiments to evaluate the influence of the oxygen pressure, catalyst, absorption solution, reduction reagent, bomb cooling time, and a combustion aid on the combustion of coal in an oxygen bomb. Response surface methodology was conducted to further refine the results obtained by fractional factorial design and to define parameters for the procedure. The accuracy and precision of combustion with ion chromatography were evaluated by the use of two certified reference materials and by fortified in-house ...

Isotopes of americiumIsotopes of americium
Americium (95Am) is an artificial element, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no known stable isotopes. The first isotope to be synthesized was 241Am in 1944. The artificial element decays by ejecting alpha particles. Americium has an atomic number of 95 (the number of protons in the nucleus of the americium atom). Nineteen radioisotopes of americium-223Am, 229Am, 230Am, and those ranging from 232Am to 247Am-have been characterized, with the most stable being 243Am with a half-life of 7,370 years, and 241Am with a half-life of 432.2 years. All of the remaining radioactive isotopes have half-lives that are less than 51 hours, and the majority of these have half-lives that are less than 100 minutes. This element also has 8 meta states, with the most stable being 242mAm (t1/2 = 141 years). ...

Isotopes of tinIsotopes of tin
Tin-126 is a radioisotope of tin and one of only seven long-lived fission products. While tin-126's half-life of 230,000 years translates to a low specific activity of gamma radiation, its short-lived decay products, two isomers of antimony-126, emit 17 and 40 keV gamma radiation and a 3.67 MeV beta particle on their way to stable tellurium-126, making external exposure to tin-126 a potential concern. 126Sn is in the middle of the mass range for fission products. Thermal reactors, which make up almost all current nuclear power plants, produce it at a very low yield (0.056% for 235U), since slow neutrons almost always fission 235U or 239Pu into unequal halves. Fast fission in a fast reactor or nuclear weapon, or fission of some heavy minor actinides such as californium, will produce it at higher yields. ...

Thallium (Tl) has 37 isotopes which have atomic masses that range from 176 to 212. 203Tl and 205Tl are the only stable isotopes and 204Tl is the most stable radioisotope with a half-life of 3.78 years. 207Tl, with a half-life of 4.77 minutes, has the longest half-life of naturally occurring radioisotopes. Thallium-202 (half-life 12.23 days) can be made in a cyclotron[1] while thallium-204 (half-life 3.78 years) is made by the neutron activation of stable thallium in a nuclear reactor.[2] In fully ionized state, the isotope 205Tl becomes beta-radioactive, decaying to 205Pb.[3] It means that in fully ionized state thallium has only one stable isotope - 203Tl.

There are also 35 known artificial radioisotopes, the longest-lived of which are 179Ta with a half-life of 1.82 years, 182Ta with a half-life of 114.43 days, 183Ta with a half-life of 5.1 days, and 177Ta with a half-life of 56.56 hours. All other isotopes have half-lives under a day, most under an hour. There are also numerous isomers, the most stable of which (other than 180mTa) is 178m1Ta with a half-life of 2.36 hours. Tantalum has been proposed as a "salting" material for nuclear weapons (cobalt is another, better-known salting material). A jacket of 181Ta, irradiated by the intense high-energy neutron flux from an exploding thermonuclear weapon, would transmute into the radioactive isotope 182 ...
