Embodiments described herein provide a method for forming two titanium nitride materials by different PVD processes, such that a metallic titanium nitride layer is initially formed by a PVD process in a metallic mode and a titanium nitride retarding layer is formed over a portion of the metallic titanium nitride layer by a PVD process in a poison mode. Subsequently, a first aluminum layer, such as an aluminum seed layer, may be selectively deposited on exposed portions of the metallic titanium nitride layer by a CVD process. Thereafter, a second aluminum layer, such as an aluminum bulk layer, may be deposited on exposed portions of the first aluminum layer and the titanium nitride retarding layer during an aluminum PVD process.
Press Release issued Dec 7, 2017: Titanium dioxide is a naturally occurring mineral, whose chemical formula is TiO2. Titanium dioxide is processed and refined in a very fine powder after it is mined from earth. It is produced either by sulphate or by chloride process. Rutile, ilmenite, brookite and antanese are its natural forms, which are available as bulk crystals. The U.S. Food and Drug Administration (FDA) has declared titanium dioxide as GRAS i.e. Generally Regarded As Safe for consumption. FDA also allows use of food grade titanium dioxide usage up to 1 %, without declaring it on products labels. In many consumer products such as personal care and food; titanium dioxide is used as a common additive. Titanium dioxide also provides smooth texture to products such as chocolates and doughnuts, whilst provides abrasive texture in products such as toothpastes and lotions.

Soils are facing new environmental stressors, such as titanium dioxide nanoparticles (TiO2-NPs). While these emerging pollutants are increasingly released into most ecosystems, including agricultural fields, their potential impacts on soil and its function remain to be investigated. Here we report the response of the microbial community of an agricultural soil exposed over 90 days to TiO2-NPs (1 and 500 mg kg-1 dry soil). To assess their impact on soil function, we focused on the nitrogen cycle and measured nitrification and denitrification enzymatic activities and by quantifying specific representative genes (amoA for ammonia-oxidizers, nirK and nirS for denitrifiers). Additionally, diversity shifts were examined in bacteria, archaea, and the ammonia-oxidizing clades of each domain. With strong negative impacts on nitrification enzyme activities and the abundances of ammonia-oxidizing microorganism, TiO2-NPs triggered cascading negative effects on denitrification enzyme activity and a deep ...

0020]Furthermore, the resistance to discoloration of colored titanium is greatly improved by making the average sulfur content in the range of 30 nm from the surface of the titanium oxide layer formed on the titanium surface 0.2 to 5 atomic %, so is preferable. Sulfur, contrary to the case of phosphorus, is believed to raise the chemical stability of the titanium oxide layer by being contained in a suitable quantity in the titanium oxide layer and to be remarkably effective in suppressing the dissolution of the titanium oxide layer in high temperature rainwater or in low pH rainwater. To obtain this effect, 0.2 atomic % or more of sulfur is preferably contained in the range of 30 nm from the surface of the titanium oxide layer. However, if contained in excess of 5 atomic %, conversely the dissolution of the titanium oxide layer in the above environment is easily promoted, so the preferred upper limit of the sulfur content is made 5 atomic %. Here, the sulfur content in a range of 30 nm is ...
The main objective of this paper was to study the morphology, composition and chemical state of coatings based on titanium nitride obtained using the condensation method with ion bombardment. Scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS) were used to analyse the structure and composition of the coatings produced at different formation times.. It was determined that coatings formed at different times still have a sufficiently close chemical composition and contain titanium nitride (TiN), titanium oxynitride (TiNxO1-x), titanium oxide (TiOx) and titanium carbide (TiC). The paper demonstrates that the increase in the formation time of coatings leads to a decrease in the proportion of carbon in the amorphous state and an increase in the fraction of carbon which is a part of titanium carbides. In the composition of coatings formed in 15 and 50 minutes, the fraction of carbon chemically bonded to titanium differs by a factor ...

Titanium is a very strong metal that is used in special applications. It is chemical element number 22 on the periodic table. Its symbol is Ti. It has 22 electrons and 22 protons. The most common isotope has 26 neutrons. Titanium was discovered in 1791 by William Gregor. Titanium can combine with other chemicals to make different materials. When titanium mixes with oxygen from the air, it forms titanium dioxide (TiO2), or titania. Titanium dioxide is a white pigment that is often used to make things less transparent, brighter, or rougher - because it does not react with chemicals inside the human body, it is safe to use in foods and other applications, like toothpaste. Pieces of titanium metal are protected by a shell of titanium dioxide, which forms when the metal is in the air and helps prevent chemicals from damaging the metal center. Titanium alloys are used in aerospace engineering to make very strong and light parts of airplanes. These alloys can replace steel because they are almost as ...
Introduction Titanium dioxide is a white pigment which is used in paints, plastics, paper, pharmaceuticals, cosmetics, sunscreen, and toothpaste or as catalyst.[1,2,3] In addition, it has been approved as a food additive (ingredient number E171) since 1969.[4] The main food categories containing titanium dioxide are candy, bakery wares (esp. icing and decorations), chewing gum, ice cream, and cheese.[2] Most food-grade titanium dioxide contains its anatase modification.[3] It is highly stable towards various conditions (e.g. heat, light, pH) and thus unaffected by almost every type of food processing. The French Agency for Food, Environmental and Occupational Health & Safety found in 2019 that there was not enough evidence to prove titanium dioxide was safe for human consumption. In consequence, the French government will ban titanium dioxide in food starting January 2020.[2,6] These concerns have arisen following recent studies which considered nanoparticles of TiO2 to be harmful after oral ...

Titanium dioxide is the most widely used white pigment because of its brightness and very high refractive index, in which it is surpassed only by a few other materials. Approximately 4.6 million tons of pigmentary TiO2 are used annually worldwide, and this number is expected to increase as utilization continues to rise.[28] When deposited as a thin film, its refractive index and colour make it an excellent reflective optical coating for dielectric mirrors and some gemstones like mystic fire topaz. TiO2 is also an effective opacifier in powder form, where it is employed as a pigment to provide whiteness and opacity to products such as paints, coatings, plastics, papers, inks, foods, medicines (i.e. pills and tablets) as well as most toothpastes. In paint, it is often referred to offhandedly as the perfect white, the whitest white, or other similar terms. Opacity is improved by optimal sizing of the titanium dioxide particles. Some grades of titanium based pigments as used in sparkly paints, ...

Nanosized titanium dioxide, particularly in the anatase form, exhibits photocatalytic activity under ultraviolet (UV) irradiation. This photoactivity is reportedly most pronounced at the {001} planes of anatase,[44][45] although the {101} planes are thermodynamically more stable and thus more prominent in most synthesised and natural anatase,[46] as evident by the often observed tetragonal dipyramidal growth habit. Interfaces between rutile and anatase are further considered to improve photocatalytic activity by facilitating charge carrier separation and as a result, biphasic titanium dioxide is often considered to possess enhanced functionality as a photocatalyst.[47] It has been reported that titanium dioxide, when doped with nitrogen ions or doped with metal oxide like tungsten trioxide, exhibits excitation also under visible light.[48] The strong oxidative potential of the positive holes oxidizes water to create hydroxyl radicals. It can also oxidize oxygen or organic materials directly. ...

Increasing evidence shows that lungs can be damaged by inhalation of nanoparticles (NPs) at environmental and occupational settings. Recent findings have associated the exposure to iron oxide (Fe2O3) and titanium dioxide (TiO2) - NPs widely used in biomedical and clinical research - with pulmonary oxidative stress and inflammation. Although changes on cellular mechanics could contribute to pulmonary inflammation, there is no information regarding the effects of Fe2O3 and TiO2 on alveolar epithelial cell biomechanics. The aim was to investigate the NPs-induced biomechanical effects in terms of cell stiffness and traction forces exerted by human alveolar epithelial cells. Cell Youngs modulus (E) measured by atomic force microscopy in alveolar epithelial cells significantly decreased after exposure to Fe2O3 and TiO2 (∼28 and ∼25%, respectively) compared to control conditions. Moreover, both NPs induced a similar reduction in the traction forces exerted by the alveolar epithelial cells in comparison to

Many of titaniums physical and mechanical properties make it desirable as a material for implants and prosthesis. The strength and rigidity of titanium is comparable to those of other noble or high noble alloys commonly used in dentistry, and titaniums ductility, when chemically pure, is similar to that of many dental alloys. Titanium can also be alloyed with other metals, such as aluminum, vanadium or iron to modify its mechanical properties.. The low density of titanium provides for high-strength, lightweight prosthesis. Additionally, dental porcelain can be fused and bonded to titanium to produce an aesthetic, lifelike restoration.. Titanium has been used in cast dental prosthesis since the 1970s. Equipment is available to cast titanium into single-and multiple-unit-crown-and-bridge frameworks, implant-supported structures and partial or full denture bases.. For more than 25 years, titanium has been used for both endosseous and subperiosteal implants. Endosseous implants have taken the form ...

The goal of our research was to prove that dental follicle stem cells are a valuable cell source in improving bone regeneration on titanium implants surfaces. The dental follicle harvesting procedure is easy to undertake since it can be performed in relation to several surgical operations, impacted tooth extraction or even less invasive tooth disclosure. The search for alternative sources of mesenchymal stem cells (such as the dental follicle) is of considerable importance because bone marrow aspiration is an invasive procedure [1] and there are significant age-related decreases in the frequency and differentiation potential of bone-marrow-derived MSCs [12]. Compared to other stem cell sources from the oral cavity, as tooth pulp, the dental follicle is a considerably larger tissue [2], is easily accessible and dental follicle stem cells have a higher proliferation capacity than stem cells from the tooth pulp [13].. One innovative aspect of this study is that the follicular sac can be harvested ...

Titanium and its Application to the Blackbird SR-71 OVERALL SUMMURY OF TITANIUM:. William Gregor discovered titanium in 1791, it was first isolated and named after the powerful mythological first sons of the Earth - The Titans, titanium used mostly in jet engines and aircraft, but most recently it has been used widely in the prosthetic industry and the artificial heart. Titanium is the worlds fourth most abundant structural metal. It is found in North and South America, Europe, Africa and Australia in its ore. The most widely used extraction method of titanium from its ore is the Kroll process, which uses magnesium as the reducing agent to extract the titanium from its ore.. Titanium is number 22 on the periodic table. It is has a very high melting and boiling point, which enables it to be used in many situations where other metals would simply melt. It also has a very low density, this is what favours titanium to many other metals as it is light and very strong. ...
TY - JOUR. T1 - Antimicrobial loading of nanotubular titanium surfaces favoring surface coverage by mammalian cells over bacterial colonization. AU - Ren, Xiaoxiang. AU - van der Mei, Henny C.. AU - Ren, Yijin. AU - Busscher, Henk J.. AU - Peterson, Brandon W.. PY - 2021/4. Y1 - 2021/4. N2 - Titanium is frequently used for dental implants, percutaneous pins and screws or orthopedic joint prostheses. Implant surfaces can become peri-operatively contaminated by surgically introduced bacteria during implantation causing lack of surface coverage by mammalian cells and subsequent implant failure. Especially implants that have to function in a bacteria-laden environment such as dental implants or percutaneous pins, cannot be surgically implanted while being kept sterile. Accordingly, contaminating bacteria adhering to implant surfaces hamper successful surface coverage by mammalian cells required for long-term functioning. Here, nanotubular titanium surfaces were prepared and loaded with Ag ...

Y1 - 2014. N2 - The influence of heterogeneous semiconductors on the photodegradation of phenol in water was investigated using doped tin dioxide (SnO2) nanoparticles. Photocatalysts of SnO2 were synthesized with lanthanum (La), cerium (Ce), and neodymium (Nd) dopants. These photocatalysts were synthesized from tin tetrachloride by sol-gel method with different dopant concentrations, and its photocatalytic degradation was investigated up to 0.8 % under UV-A light in aqueous suspensions. The photocatalytic oxidation reactions were studied by varying photocatalyst composition, light intensity, reaction time, pH of the reaction medium, and phenol concentration. It was found that the photocatalytic activity of rare earth-doped SnO2 for phenol decomposition under UV light irradiation was considerably higher ...
The use of nanoparticles in foods is increasing every year, but we still know very little about whether they have health risks to humans, especially if one is eating foods with them daily (thus having chronic exposure). The nanoparticles in foods are ingredients so small that they are measured in nanometers or billionths of one meter. The most common nanoingredients are: titanium dioxide, silicon dioxide, and zinc oxide. Titanium dioxide is typically used as a food coloring to make foods whiter or brighter, but it may or may not be listed on the label. In Europe, this food additive is known as E171. Currently there are no restrictions on using titanium diaoxide nanoparticles in food.. Recent search suggests that there may be health effects from the nanoparticles in our food (here and here), thus we should be cautious. Evidence is accumulating that titanium dioxide nanoparticles can have a negative inflammatory effect on the intestinal lining. Similarly, a new study looking at both mice and ...
There are two basic types of titanium body jewelry: solid titanium, and anodized or electroplated titanium, which is a hard titanium coating placed over another metal. In most piercing jewelry, an anodized titanium coating will be made over surgical grade stainless steel to add durability and color. Anodized titanium
A method for forming reactive metal silicide layers at two spaced locations on a silicon substrate, which layers can be of different thicknesses and/or of different reactive metals is provided. A sililcon substrate has a silicon dioxide layer formed thereon followed by the formation of a polysilicon layer on the silicon dioxide layer, followed by forming a layer of refractory metal, e.g. titanium on the polysilicon. A non-reflecting material, e.g. titanium nitride is formed on the refractory metal. Conventional photoresist techniques are used to pattern the titanium nitride, the titanium and polysilicon, and the titanium is reacted with the contacted polysilicon to form a titanium silicide. The portion of silicon dioxide overlying the silicon substrate is then removed and the exposed substrate is ion implanted to form source/drain regions. A second layer of refractory metal, either titanium or some other refractory metal, is deposited over the source/drain region, and either over the titanium nitride,
CP 2 is the purest grade of titanium available. This grade is best for people who actually do have known allergies to certain metals, especially those who have experienced rashes due to aluminum or tin.. The strength of titanium makes the creation of elaborate designs very difficult. Elegant designs are meant to capture the beauty of the metal and of any stones in the piece. But, a simplistic approach is often taken when molding this metal into jewelry.. The classic designs are very popular with men who may be concerned about wearing excessively feminine-appearing titanium wedding rings. As you may well imagine, unadorned mens wedding bands have always been more popular among the male species.. For couples interested in matching wedding bands, most jewelers are more than happy to create custom pieces to match the desires of the customer. There are countless ways to mount jewels into titanium, as well as options available for coloring a piece of titanium jewelry.. Titanium is a refractory metal. ...

Abstract The aim of this study was to compare the nucleating and crystal growth behaviour of calcium phosphates on four types of potentially bioactive surfaces, using the simulated body fluid (SBF) model with added fibrinogen. Blasted titanium discs were modified by alkali and heat treatment, anodic oxidation, fluoride treatment, or hydroxyapatite coating. The discs were immersed in SBF with fibrinogen for periods of 3 days and 1, 2, 3 and 4 weeks. The topography, morphology, and chemistry of the surfaces were evaluated with optical interferometry, scanning electron microscopy/energy dispersive X-ray analysis (SEM/EDX), and x-ray photoelectron spectroscopy (XPS), respectively. All surface modifications showed early calcium phosphate formation after 3 days, and were almost completely covered by calcium phosphates after 2 weeks. After 4 weeks, the Ca/P ratio was approximately 2.0 for all surface groups except the fluoride modified surface, which had a Ca/P ratio of 1.0-1.5. XPS measurements of the
The nanoparticles actually blunted the effectiveness of the small intestines microvilli. Microvilli are tiny projections that jut off of small intestinal cells and work to absorb nutrients our bodies need to survive. (3). People also face this type of titanium dioxide exposure through toothpaste, and its even sometimes used to created a smoother texture in chocolates and to create a brighter appearance in skim milk.. In 2012, Arizona State University found that titanium dioxide nanoparticles turned up in five percent of products tested, including Twinkies and mayonnaise samples. Under public pressure, Dunkin Donuts stopped using nano-titanium dioxide in its donuts powdered sugar in 2015.. To avoid foods rich in titanium oxide nanoparticles you should avoid processed foods, and especially candy. That is where you see a lot of nanoparticles, - Gretchen Mahler, PhD, study co-author and assistant professor of biomedical engineering at Binghamton University, State University of New York. ...

An adherent bioactive calcium phosphate coating is formed on a titanium or titanium alloy substrate by immersing the substrate in an acidic calcium phosphate solution to form a non-apatitic calcium phosphate coating on the substrate. In a second step the coated substrate can be converted to a less reactive coating by being immersed into a basic or neutral solution to convert the coating into an apatite. However if a relatively reactive coating is desired, the second step can be dispensed with.
We describe herein biocompatible single crystal Cu-based shape memory alloys (SMAs). In particular, we show biocompatibility based on MEM elution cell cytotoxicity, ISO intramuscular implant, and hemo-compatibility tests producing negative cytotoxic results. This biocompatibility may be attributed to the formation of a durable oxide surface layer analogous to the titanium oxide layer that inhibits body fluid reaction to titanium nickel alloys, and/or the non-existence of crystal domain boundaries may inhibit corrosive chemical attack. Methods for controlling the formation of the protective aluminum oxide layer are also described, as are devices including such biocompatible single crystal copper-based SMAs.

Naturally occurring perchlorate has been observed in playa areas of the western United States, in nitrate deposits from northern Chile, and has also been observed at low concentrations in surface and groundwater in the southwestern United States, distant from industrial sources. Studies were conducted to determine if perchlorate could be formed when dry chloride salts were exposed to sunlight and laboratory ultraviolet light in the presence of desert soils and titanium dioxide. Several desert soils were surveyed to determine which soils contained the highest amounts of naturally occurring perchlorate. A soil from Death Valley (29/μg/kg) and a soil from the Black Rock Desert (16 μg/kg) were selected, along with titanium dioxide for further studies. The soils were washed to remove the existing perchlorate; additional chloride was added and exposed to sunlight and ultraviolet light for 1-4 months. Perchlorate was generated in both sunlight and ultraviolet light on the soils (,4-29 μg/kg). Higher ...
The application of Nitinol shape memory alloys (SMA) in steel connections is evaluated using connections incorporating SMA tendons. Shape memory alloys are a class of alloys that exhibit thermo-mechanical characteristics that are ideally suited for seismic applications. They have the ability to dissipate significant energy with little permanent deformation, and possess highly reliable energy dissipation based on a repeatable solid state phase transformation. To assess the validity of using SMA in real structures, two full-scale connections are tested. The tests are conducted on exterior joint specimens and tested according to the SAC testing protocol. The beams are W24 x 94 and the columns W14 x 159, all of A572 Grade 50 steel. Companion regular steel connections are tested for comparison. The connections are of a T-stub type, with four 11/2 inch diameter SMA rods providing the tensile resistance to the column. The specimens are re-tested several times to determine the ability of the SMA rods to ...

Actuator concepts utilizing NiMnGa, ferromagnetic shape memory alloy are investigated for potential use on a smart rotor for trailing edge flap actuation. With their high energy density, large dynamic stroke, and wide operating bandwidth, ferromagnetic shape memory alloys (FSMA) like NiMnGa, seem like attractive candidates for smart rotor actuators, potentially able to fulfill the requirements for both primary rotor control and vibration suppression. However, because of the recent discovery of the material, current experimental data and analytical tools are limited. To rectify these shortcomings, an extensive set of detailed experiments were conducted on samples of NiMnGa to characterize the response of the alloy for a wide variety of mechanical and magnetic loading conditions. Measurements of the material performance parameters such as power density, damping properties, magneto-mechanical coupling, and transduction efficiency were included. Once characterized, the experimental data were used to ...
Single crystal Ni-Mn-Ga ferromagnetic shape memory alloys (FSMAs) are active materials which produce strain when a magnetic field is applied. The large saturation strain (6%) of Ni-Mn-Ga, and material energy density comparable to piezoelectric ceramics make Ni- Mn-Ga an interesting active material. However, their usefulness is limited by the bulky electromagnet required to produce a magnetic field. In this thesis, a novel actuation method is developed for shape memory alloys in their martensitic phase, whereby asymmetric acoustic pulses are used to drive twin boundary motion. Experimental actuators were developed using a combination of Ni-Mn-Ga FSMA single crystals and a piezoelectric stack actuator. In bi-directional actuation without load, strains of over 3% were achieved using repeated pulses (at 100 Hz) over a 30 s interval, while 1% strain was achieved in under 1 s. The maximum strains achieved are comparable to the strains achieved using bi-directional magnetic actuation, although the time ...
Titanium tweezers have been found to be excellent for use in the silicon chip industry, as titanium tweezers do not shed particles like the stainless steel tweezers. Anytime an abrasive substance is handled and microscopic particles are a detriment, it may be best to choose titanium. Since titanium is non-magnetic, these tweezers are extremely useful when handling magnetic materials or when working in a magnetic field. Titanium is both light weight and high strength material.. ...
The primary goal of the Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART) is to enable the design of revolutionary applications based on shape memory alloy (SMA) technology. In order to help realize this goal and reduce the development time and required experience for the fabrication of SMA actuation systems, several modeling tools have been developed for common actuator types and are discussed herein along with case studies, which highlight the capabilities and limitations of these tools. Due to their ability to sustain high stresses and recover large deformations, SMAs have many potential applications as reliable, lightweight, solid-state actuators. Their advantage over classical actuators can also be further improved when the actuator geometry is modified to fit the specific application. In this paper, three common actuator designs are studied: wires, which are lightweight, low-profile, and easily implemented; springs, which offer actuation strokes upwards ...
