LONDON - Borosilicate glass is a kind of glass containing such main glass-forming constituents as boron trioxide and silica. Borosilicate glasses are widely recognized for having low coefficients of thermal expansion, which makes them resistant to thermal shock much more than any other common glass. Borosilicate glass finds numerous applications, for instance in healthcare, electronics, cookware, lightning, optics industries, among others.. Shandong Yaohua, Schott, Sunshore, JiangSu YuanSheng, MAXOS, Changzhou Tianxiang, Kimble, Hanzhong Xinhai, Corning, REFMEX GL, Kavalier, NEG, Shandong Linuo, Jiangsu Sunrain and Huailai Tianyuan are among the top players in the industry..

Back in March 2018 Lorraine Finch, a photograph conservator, gave the archive team some valuable training on identifying different photographic processes and how to care for the different types of photographic material. We were aware that among the various photographic formats held in the Jesuits in Britain Archives there was a collection of glass plate negatives.. Before cellulose nitrate film was invented in 1903, photographic emulsions were made on glass supports, more typically known as glass plate negatives, and this enabled amateur as well as professional photography to flourish. There are two separate glass plate negative photographic methods which both consist of a light sensitive emulsion fixed to the glass plate base with a binder. In 1851, at almost the same time, Frederick Scott Archer (1813-1857) and Jean-Baptiste Gustave Le Gray (1820-1884) produced the first collodion wet plate negatives. Wet plate negatives were produced by spreading a glass plate with collodion, bathed in silver ...

Bioresorbable (or bioabsorbable) metallic glass is a type of amorphous metal, which is based on the Mg-Zn-Ca ternary system. Containing only elements which already exist inside the human body, namely Mg, Zn and Ca, these amorphous alloys are a special type of biodegradable metal. The first reported metallic glass was an alloy (Au75Si25) produced at Caltech by W. Klement (Jr.), Willens and Duwez in 1960. This and other early glass-forming alloys had to be cooled extremely rapidly (in the order of one mega-kelvin per second, 106 K/s) to avoid crystallization. An important consequence of this was that metallic glasses could only be produced in a limited number of forms (typically ribbons, foils, or wires) in which one or more dimensions were small so that heat could be extracted quickly enough to achieve the necessary cooling rates. As a result, metallic glass specimens (with a few exceptions) were limited to thicknesses of less than one hundred micrometers. Mg-Zn-Ca based metallic glasses are a ...

The effects of the addition of divalent metal oxides on the structure and thermophysical properties of the mixed alkali borosilicate glass system used for high level radioactive waste immobilisation have been studied. Densities, molar volumes, linear thermal expansivities and glass transition temperatures are reported and structural information has been obtained using B-11 and Si-29 magic angle spinning (MAS) NMR. Molar volume is controlled by ion size and by the formation of network polyhedra, whilst thermal expansion reflects the network rigidity. Changes in the glass transition temperature, T-S, are consistent with the different values of the heat of formation of the oxides added. Alkaline earth oxides produce an initial increase in the fraction of 4-coordinated boron, N-4, whereas PbO and ZnO reduce N-4. Si-29 NMR of the alkaline earth oxide glasses shows the presence of significant concentrations of nonbridging oxygens, consistent with a previous study of the aqueous corrosion behaviour of ...

Following the success of bioactive glass in orthopaedic applications, bioactive glass was adopted for use in dentistry applications. It has shown substantial benefit in the repair of periodontal defects.4 The observed antimicrobial activity alongside its demonstrated high strength made bioactive glass a prime candidate for tooth fillings. Fillings made with bioactive glass should slow secondary tooth decay by inhibiting bacterial colonization and increase the durability of composite filling materials. Furthermore, it was hypothesized that the bioactive glass may also provide minerals to strengthen the damaged surface of the tooth.. Evaluations of bioactive glass as a tooth filling have recently shown that such extrapolations to dentistry are indeed correct. Studies have demonstrated that the addition of bioactive glass to dental filling materials enhanced mineral formation in the dentin, promoting remineralization of dental caries7 and improved the mechanical properties of a filling in an ...

Glass transition and crystallization behavior of several Mg-Ni-Nd metallic glasses has been systematically studied by temperature-modulated differential scanning calorimetry (TMDSC). The glass transition transformation of alloys Mg75Ni10Nd15 and Mg77Ni 18Ni5, which cannot be detected in conventional differential scanning calorimetry (DSC) heating scans, was observed through TMDSC measurements. It was concluded that the signal of the glass transition on the DSC scans overlapped with the relatively large heat release from the primary crystallization of either intermetallic Mg3Nd phase in glassy Mg75Ni10Nd15 alloy or Mg2Ni phase in amorphous alloy Mg77Ni18Ni5. Increasing the content of Ni in alloy Mg75Ni10Nd 15 can suppress the precipitation processes of Mg3Nd, and results in the appearance of glass transition transformation on DSC heating curves. This confirmed and verified our TMDSC measurements. Clear observation of glass transition and understanding of crystallization micro-mechanism in such ...

Perovskite [(Ba0.6Sr0.4)TiO3]-[2SiO2-B2O3]-[K2O]-La2O3 glass was prepared by conventional melt quench method. The differential thermal analysis (DTA) was performed on glass sample in the temperature range from 100℃ to 1000℃ by different heating rate to study the crystallization kinematics. The kinetic parameters characterizing the crystallization have been determined using an Arrhenius model. Glass samples were subjected to appropriate heat treatment schedules for their suitable crystallization. X-ray diffraction analysis (XRD) of glass and glass ceramic samples were done to check the amorphous state and crystalline nature. XRD of glass ceramic sample shows the major perovskite phase of BaTiO3 (BT) along with the formation of secondary phases Ba2TiSi2O8 (BTS) and Ba2Ti2B2O9 (BTB). Scanning electron microscopy (SEM) is also studied to see the morphology of the grains of major and secondary phase formation in BST glass ceramic samples. La2O3 is played an important role to increase the nucleation of

Bioglass 45S5, commonly referred to by its commercial name Bioglass, is a glass specifically composed of 45 wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O, and 6.0 wt% P2O5. Glasses are non-crystalline amorphous solids that are commonly composed of silica-based materials with other minor additives. Compared to soda-lime glass (commonly used, as in windows or bottles), Bioglass 45S5 contains less silica and higher amounts of calcium and phosphorus. The 45S5 name signifies glass with 45 weight % of SiO2 and 5:1 molar ratio of calcium to phosphorus. This high ratio of calcium to phosphorus promotes formation of apatite crystals; calcium and silica ions can act as crystallization nuclei. Lower Ca:P ratios do not bond to bone. Bioglass 45S5s specific composition is optimal in biomedical applications because of its similar composition to that of hydroxyapatite, the mineral component of bone. This similarity provides Bioglass ability to be integrated with living bone. This composition of bioactive glass is ...
The conversion of bioactive glass to a calcium phosphate material, typically hydroxyapatite (HA), by solution-precipitation reactions in aqueous phosphate solution, has been commonly reported. This paper describes the structural and compositional characteristics of the calcium phosphate material formed during the early-stage conversion (o5 h) of a borosilicate glass (designated H12) in aqueous phosphate solution. Disks of H12 glass were reacted with 0.25M K2HPO4 solution with a starting pH57.0 at 371C. The structure and composition of the product layer were characterized using thin film X-ray diffraction, scanning electron microscopy, and Fourier transform infrared reflectance spectroscopy. For reaction times o5 h, the results indicated the formation of brushite (CaHPO4 .2H2O) with coarse, plate-like crystals. In comparison, the formation of HA with small needle-like crystals was found at later times. This early-stage formation of brushite has not been reported in previous studies of converting

In June 2011, the National Toxicology Program (NTP) removed from its Report on Carcinogens all biosoluble glass wool used in home and building insulation and for non-insulation products.[24] However, NTP considers fibrous glass dust to be reasonably anticipated [as] a human carcinogen (Certain Glass Wool Fibers (Inhalable)).[25] Similarly, Californias Office of Environmental Health Hazard Assessment (OEHHA) published a November, 2011 modification to its Proposition 65 listing to include only Glass wool fibers (inhalable and biopersistent).[26] The actions of U.S. NTP and Californias OEHHA mean that a cancer warning label for biosoluble fiber glass home and building insulation is no longer required under federal or California law. All fiberglass wools commonly used for thermal and acoustical insulation were reclassified by the International Agency for Research on Cancer (IARC) in October 2001 as Not Classifiable as to carcinogenicity to humans (Group 3).[27].

The properties of 3 and 6 mol % copper-containing bioactive glasses have been evaluated. The structure of the doped glass has been studied by X-ray diffraction (XRD), X-ray photoelectron survey (XPS), high-resolution scans and NMR spectroscopy. The results indicated that copper acts as a network modifier in the glass composition and copper-containing glasses show a less connected microstructure. Differential Thermal Analysis (DTA) showed that the copper addition in the glass lowers the glass transition temperature. Antibacterial studies showed that doping with copper enhances the antibacterial effect of the bioglass.. ...

Pulsed electrical discharge (PED) is a method that has been employed to fabricate metallic glass (MG) layers on Al-Cu-Mg-(Zn) alloys. Abnormal Al and Cu element segregation has been found on the alloys vitrified surfaces after PED treatment. Surface element evaporation was found and proven to be the main reason for such significant segregation. Benefits to the evaporation of the non-corrosion resisting elements in the MG layers, the corrosion resistance, and the surface hardness of Al-Cu-Mg-Zn alloys have been greatly improved. The average corrosion rates of Al-Cu-Mg-Zn alloys with MG layers were reduced to about 2% of that without MG layers. Additionally, the surface hardness of Al-Cu-Mg-Zn alloys with MG layers was increased to 537.173 (±7) HV0.1. PED treatment is a promising way to synthesize MG layers with controllable element proportions and distributions for wear- and corrosion-resistant coatings on traditional Al-Cu-Mg-Zn alloys.

We report that a series of lanthanide-based bulk metallic glasses show a pressure-induced polyamorphic phase transition observed by in situ angle-dispersive x-ray diffraction under high pressures. The transition started from a low-density state at l
We have studied the relationship between the initial glass composition and the structural changes associated with laser-induced refractive index modification in a series of Er-Yb doped and undoped zinc phosphate glasses. White light microscopy and waveguide experiments are used together with Raman and fluorescence spectroscopy to characterize the structural changes. The correlation between Raman peak shifts and fluorescence from phosphorus-oxygen hole center (POHC) defects indicates that fs-laser writing results in a depolymerization of the phosphate glass network. The results also show that the exact glass composition should be taken into account when fabricating waveguide devices in phosphate glasses, in order to both expand the fs-laser processing conditions and maximize favorable morphological changes for 3-D photonic devices. © 2011 Optical Society of America.

Hollow glass microspheres made from a low heat conductivity glass composition containing a high vacuum and a thin metal coating deposited on the inner wall surface of the microspheres are described. The hollow glass microspheres are used to make superior insulation materials in the construction of highly efficient solar energy collectors. The hollow glass microspheres are made by forming a liquid film of molten glass across a coaxial blowing nozzle, applying a metal vapor blowing gas at a positive pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film of molten glass. A transverse jet is used to direct an inert entraining fluid over and around the blowing nozzle at an angle to the axis of the blowing nozzle. The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.

Four types of surface-modified glass were prepared. Aminopropyl glass was prepared by alkylsilylation of glass slides with ?-aminopropyltriethoxysilane. This glass carries primary amino groups which may be protonated at pH 7.2. Owing to the presence of both positively charged ions and hydrophobic ethoxyl groups, the glass is considered to be amphipathic. Three other types of surface-modified glass slides were prepared from aminopropyl glass by forming Schiff's bases with three aldehydes: glucose, glyoxylic acid and hexanal. The aldehyde-treated slides were subsequently reduced using sodium borohydride. Thus, the surface of the glass was rendered hydrophilic, ampholytic or hydrophobic, respectively. The adherence of two Streptococcus sanguis strains and two Streptococcus mutans strains to the surface-modified glass slides was studied. Different strains showed differences in adherence to these slides depending on their physico-chemical surface properties. For S. sanguis ATCC 10556, hydrophobic bonds
There are two types of viscosity that we usually deal with; kinematic and dynamic viscosity. Kinematic viscosity is a measure of a fluids internal resistance to flow under the force of gravity, and is usually given in the units of centistokes, cSt. Dynamic viscosity is a measure of a fluids resistance to flow when there is an external force, and has the units of centipoise, cP. For pump analysis dynamic viscosity is generally more useful, but kinematic viscosity does have application - especially for Newtonian liquids, and if you find yourself needing to measure the kinematic viscosity then a glass capillary is the simplest way.. The glass capillary is usually several hundred millimeters tall, and is made with precise length and inside diameter dimensions. It will have show two marks on the capillary, and the kinematic viscosity is determined by simply measuring the time it takes for a known quantity of the liquid to flow through the capillary between the two marks, and multiplying it by a ...

A few weeks ago I was introduced to the Libre tea glass company. These beautifully designed and extremely practical tea infusion glass are ideal for those individuals who enjoy loose tea or fruit flavored beverages. The tea glasses are constructed in four parts, with the a glass inner, a poly outer, a stainless steel filter and a spill proof top. It is the perfect gift for your favorite tea lover.. For this review, I chose the large Lively Leaves tea glass. I expected the bottle to be heavier but it really feels about the same as your standard glass or stainless steel bottles. The glass fits easily into my hands and I have no problem drinking from it. I wouldnt mind the option to buy a slide lid so that I could use it at my desk at work. Instead I just pour into a smaller spill proof cup.. The infusion process is very simple. You simply put in what ever loose leaf tea, fruit, vegetables or herbs, fill with water and drink. I noticed that the cold infused tea takes a bit longer to brew but I ...
TY - JOUR. T1 - Healing of interfaces of high and ultra-high-molecular- weight polystyrene below the bulk glass transition temperature.. AU - Boiko, Yuri M.. AU - Lyngaae-Jørgensen, Jørgen. PY - 2004. Y1 - 2004. N2 - Amorphous bulk samples of high-molecular-weight (HMW) polystyrene (PS) with a weight-average molecular weight M-w of 102.5 kg/mol and a number-average molecular weight M. of 97 kg/mol and of ultra-high-molecular-weight PS (UHMWPS) with M-w=1110.5 kg/mol and M-n = 965.6 kg/mol were brought into contact to themselves below the glass transition temperature T-g of the bulk Tg-bulk, in a lap-shear joint geometry, at a constant healing temperature T-h for a healing time t(h) of 10 min to 24 h. The lap-shear strength sigma of the symmetric HMWPS-HMWPS and UHMWPS-URMWPS interfaces has been measured at the ambient temperature. Larger values of sigma have always been measured for the HMWPS-HMWPS interface after healing at the same conditions. However, the difference between the values of a, ...
