Knowing the interesting chemical elements boron B comes from afar

Boron has been a major name in the world of chemistry. There have been two Nobel Prizes in Chemistry for the work done on boron.

There are a few heat-resistant products on the market that have boric acid added to the glass. This means the glass will not expand or contract easily after joining.

Diamond is the hardest substance known to man. However, recent theories suggest it may not be the case.

Boron compounds have a number of interesting properties. They play a crucial role in polymer crosslinking, which gives plasticine a remarkable ability. It is soft and malleable when held in your hands but becomes hard and elastic if you throw it at a wall.

Boric acid is a compound that contains boron and it's often used as a medicine or to kill insects. Boric Acid can be used for eye disinfection, especially in high school and middle school chemistry labs.

Compound Name TiH2 Powder Titanium Hydride Application For Welding And Catalysts

The titanium hydride used is a getter, in the electric vacuum method, as hydrogen source for metal foam production, and as source of pure hydrogen. Also, it can be found in powder metallurgy and metal-ceramic sealing to provide titanium to the alloy.

Titanium Hydride is very fragile and can be used for powdered titanium. The hydride is also used to weld. Thermal decomposition of titanium hydride precipitates new, ecological hydrogen and Titanium metal. This increases the strength and promotes welding.

PNNL's collaborators and PNNL discovered a method to get around this issue six years in advance. They additionally developed a low cost way of supplying material at a commercial scale. Instead of starting with molten Titanium, the team substituted titanium-hydride (TiH2) Powder.

In the last few years, an alternative BE PM-Ti approach has been developed that allows for production of BE components which are almost poreless at one time. This method uses vacuum sintering titanium hydride (TiH2) instead of Ti-steel powder. TiH2 powders will dehydrogenate during the entire sintering process at mild temperatures, before being sintered under vacuum at high temperature.

Current implant requirements include biocompatibility and bone-like mechanical properties. Porous Titanium can meet these needs if enough porosity is obtained, as well as large pores and interconnections that allow bone to grow. Porous components are created from TiH2 based feedstocks with space holders.

Newly 3000°C Ablative Ceramic Coating Successfully Developed - Multi-boron-containing Single-phase Carbide

Boron carbide is also known as black Diamond. It has a molecular structure of B4C. The powder is typically grayish. It is one the hardest materials known (the other two being diamond and cubic boronnitride), which can be found in many industrial applications, including tank armor. It has a Mohs toughness of 9.3. A large number of tests were conducted by the team of Academician Huang Boyun of Central South University’s National Laboratory of Powder Metallurgy to develop a new ceramic coating and composite materials that are resistant to 3000°C ablation. This discovery may pave a way for the development hypersonic cars.

According to Professor Xiong Xiang of the Institute of Powder Metallurgy of Central South University's Institute of Powder Metallurgy (IPM), hypersonic flight is defined as a flight at a speed equal or greater than five times the speed of the sound, which is approximately 6,120 kilometers per hours. With such high speeds, a flight from Beijing to New York could be completed in just 2 hours if key structural components can withstand air friction and hot-air impact of 2000-3000 deg. C. . Central South University has developed ceramic composite materials and coatings for ultra-high temperatures that provide better protection of the above components. The world's very first synthesis of a single-phase quaternary boron carbide ultra-high-temperature ceramic material has been reported. This coating is a perfect "fusion" between carbon-carbon. The current focus of research in the area of new materials is on the mixed materials of binary compound system. The successful application of materials based on quaternary systems in the hypersonic field will be greatly facilitated by its development.

The novel ceramic coated modified carbon/carbon material is composed by a single-phase carbide containing boron and zirconium. It also contains titanium, carbon, and boron. Infiltration of a multiceramic phase is the main method for obtaining it. The ultra high temperature ceramic combines the high-temperature adaptability of carbides and the anti-oxidation property of borides. This makes the coatings, composites and materials exhibit superior ablation and thermal shock resistance. The ceramic oxide can withstand an ultra-high temperature of 3000 degC and has low oxygen diffusion rates, self-healing properties at high temperatures, dense and gradient ceramic coatings, all of which make the ceramic a lighter material. Ablation loss rate.

"Because the ultra-high-temperature ceramic combines carbides' high temperature adaptability with borides' anti-oxidation properties, the coatings and materials above have superior ablation and thermal shock resistance. This is essential for hypersonic cars. "The promising parts," said Xiong Xiang.

Nature Communications published the results of research conducted by the team on 15th June. The State Key Laboratory of Powder Metallurgy of Central South University was the first unit to complete the thesis. Zeng Yi and Professor Xiong Xiang are the first correspondents. First author is the doctor. The University of Manchester (UK), a partner unit of the University of Manchester, UK characterized and analysed the material.

After publication, the article attracted a great deal of interest from the foreign media and academic circles. The downloads of the article exceeded 5,000 in the three days immediately following publication. The Daily Mail in Britain, The Economist in the United States and Public Machinery (Russia) have all covered the research. . According to the reviewer in Nature Newsletter, the above research results "will ignite academic excitement and interest in applying quaternary materials in hypersonic fields, because this material system represents a promising one."

The team began working with Professor Chang Xiang in 2002 with support from National 863,973 and National Natural Science Foundation. A scholar from Yangtze River was leading the project. Find a new ultra high temperature ceramic coating that has excellent oxidation resistance, and resistance to ablation. The material systems screened during the research included all existing high temperature ceramics, high temperature composites, zirconium and titanium carbides, zirconium and zirconium boreides, tantalum and strontium carbides. It has taken 15 years to achieve the breakthrough of developing new ablation-resistant coatings in 3000 degC ultra high temperature environment.

Controlling the electronic state of two-layer molybdenum disulfide in an origami manner

In recent years, transition metal dichalcogenide was one of the key two-dimensional quantum functional material in the world. These materials have a honeycomb like graphene but have spin-orbit coupling and a honeycomb pattern. They also have a honeycomb shape similar to graphene. As an example, molybdenum isosulfide's energy band structure evolved from an indirect band gap to a directly band gap. This greatly improved the fluorescence efficiencies and light absorption cross sections. Molybdenum sulfur has a newly discovered electronic state: the energy quantum states. It can be regarded the third internal degree freedom of electrons following charge and spin. It is important to understand the mechanisms behind these quantum phenomena in order to manipulate them. This will be of great benefit to condensed matter science and future electronics and optoelectronics.
According to Wu Shiwei the concept of this work is founded on the "ultrathin" nature two-dimensional quantum functional material: that monoatomic layer is folded directly as a piece paper, resulting in a double which cannot be produced by natural epitaxial or crystallization. Layer structure. Molybdenum Disulfide “origami” has many interlayer arrangements depending on the direction and location of the fold line. This in turn results in different macrostructure symmetry, and interlayer coupling. The research team combined first-principles computations with various experimental techniques including fluorescence spectroscopy and optical depolarization to study the electronic and space structures of various molybdenum "origami".
In addition, the change of interlayer coupling not only can greatly affect indirect band gaps in molybdenum-disulfide "origami", but it can also be used to switch the relationship between spine and electron spin when "folding the paper". Changes in interlayers can affect not only the indirect band gap, but also the relationship between spine and electron spin. This work provides an experimental platform that allows for the manipulation of interactions between multiple degrees of free will, including valley, spin and interlayer coupling.

What metal can withstand higher temperatures than tungsten

What metal is more resistant to heat than tungsten?

The melting point for tungsten, which is 3,422, is the highest of all metal elements on the periodic table (the boiling point being 5,930). No metal element is higher in melting point than the tungsten.

Tungsten is element number 74 in the VIB Group of Period 6. Each atom has the ability to form six metal bond.

There are elements that can be heated higher than tungsten. Solid carbon can reach temperatures as high as 3,627 degrees c. However, carbon does not have a fixed melting temperature (one atmosphere), because it sublimates between 3627 and 4330 degrees c.

Ta4HfC5, with a melting temperature of 4215 degrees, is currently the heat-resistant material that humans have created. It's made from tantalum carbide and hafnium carbide (melting point nearly 4000), both of which have higher melting points than tungsten.

The melting point of a material is dependent on its pressure. The higher the pressure the higher it will be. But when temperature and pressure go beyond critical, then the material becomes superfluid, losing its melting point.

Nano silver substitution trend is irreversible

Nanowires to replace infrared first
Due to the rapid growth of the display industry, as well the high processing costs of ITO films and the limited indium resources, the industry has looked for alternatives, such as nanowires. Silver nanowires, among other alternatives, are the most advantageous due to their technology and maturity. Additionally, they are flexible and can be used to replace other materials that conduct electricity with a flexible display for east wind.

Nanosilver has the most important role in Nanosilver. Nanosilver has excellent antibacterial properties and is safe.

"With the present process, silver nanowires are first to be used on a large scale as an alternative for infrared touchscreen technology. Du said, "The substitute is already obvious." "The large-size products made of silver nanowires are gaining customers' recognition.

Currently, infrared control is mainly used on the market for electronic whiteboards. Infrared transmitter tube and receiving tube is arranged on the raised border so that infrared optical networks are formed.

The next big flashpoint is 2020

The global smartphone market, with its huge population, has slowed down. However, the small and mid-sized markets will be essential for silver nanowires' mainstream adoption.

"The smartphone industry needs revolutionary innovation, whether it's facial recognition, the full screen or the hot AI feature," du said. ""Whether it is facial recognition, a full-screen, or a hot AI feature, smartphone industry needs radical innovation," du said.For the moment, foldable phones make sense. As the size of the screens increases, it becomes more difficult to carry them around. On the other hand there are new business opportunities and product experiences that can be created if they're foldable.

The last step to breaking through the nanowire

The technology of silver microwires is not widely used. The production, manufacture, storage, and patent of the silver nanowires is considered to be an important factor that limits their development.

It is not possible to replace ITO conductive film with silver nanowires. The future holds the biggest potential for completely new applications.

Molybdenum disulfide nanoelectromechanical system ultra-thin ultra-small ultra-low power consumption

As a typical, two-dimensional material graphene finds wide application in many fields. It is also highly sought after both by industry and the scientific community. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale (between 1 and 100 nm) material in which electrons are able to move freely in two directions (planar movement). Examples of such materials include: graphene; boron nitride; transition metal compounds (disulfide); Molybdenum; tungsten diulfide; tungsten diilicide; black phosphorus.
2D materials can be used in a variety of fields. Examples of 2D materials include spintronics, printed electronics, flexible electronics, microelectronics, memory, processors, hyperlenses, terahertz, supercapacitors, solar cells, security labels. , quantum dots, sensors, semiconductor manufacturing, NFC, medical, etc.


Molybdenum diulfide, also known as MoS2, is a two-dimensional material that deserves our attention. Molybdenum diulfide, which is composed of two atoms of molybdenum with one atom of sulfur, has only a three-atom thickness. The graphene thickness is nearly the same as molybdenum, but graphene has no band gap. The author of the article has previously stated that the US Department of Energy Berkeley Lab research team accurately measured band gap of semiconductor two-dimensional molybdenum-disulfide material (MoS2). They have also revealed powerful The tuning mechanisms and relationship between electronic and optical properties of 2D material.


In addition, the molybdenum diulfide has an electron mobility that is 100 cm2 /vs. (ie. 100 electrons per centimeter square per volt), although it's much lower than crystal. The silicon has an electron migration rate of about 1400 cm2/vs. However, it is better than amorphous silica and other ultra thin semiconductors.

Molybdenum diulfide, with its excellent semiconductor characteristics and small size and ultra-thinness, is ideal for use in flexible electronics, solar cells, LEDs and lasers.

Tungsten Oxide Insulation Material Can Make The Sun Room Cool in Winter and Cool in Summer

What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a molecular mass of 231.85.
It is a form of tungsticanhydride. Tungsten dioxide is not produced in industrial production. Depending on the amount of tungsten, the tungsten-trioxide salt can be divided into tungstic acids, sodium tungstates, calcium tungstates, ammonium paratungstates, ammonium métatungstates, etc.
Tungsten Trioxide is a pale-yellow triclinic powder. Once the temperature reaches 740 deg C it changes into a tetragonal orange crystal. In air, it is stable, with a melting point of 1473 deg C and a boiling point higher than 1750.
Tungsten Trioxide is one of the most stable tungsten oxydes. It is not soluble in water or inorganic acids except hydrofluoric. It is soluble with hot sodium hydroxide solution, ammonia and soluble tungstate. If the temperature is greater than 650 deg C it can reduce by H2, but at 1000-1100 C it can reduce by C to get tungsten.

The application of tungsten dioxide transparent insulation material
Smart homes make home life safer, more comfortable and more convenient. The smart home also saves energy and is environmentally friendly. So, it's not surprising to see the smart sunroom. One of these is the so-called "intelligence", which breaks the sun room into two parts: summer, like a fire stove and winter, like a refrigerator. Transparent semiconductor materials like tungsten oxide transparent materials are a good way to make the sunroom cool in summer and warm in winter. My opinion is that it's not necessary to install floor heating and air conditioning equipment. The best solution to heat insulation is to start at the source.

This concept of the smart home has already permeated our minds and is being applied everywhere! Unfortunately, this author hasn't been able live a life of intelligence. This led to the classic home scene: the author left the house every time. The result was that he forgot something, but remembered it halfway. Is your air conditioner turned off? If you don’t go back to confirm, you won't make it through the day. But go back, and you'll be late to work! What about changing to the smart home scenario? ----As soon as you lock the front door, turn the scene to unmanned, shut off the power of the terminal blocks, and check the status from the app at any time. It is easy to use, and it makes people feel more at ease.
The switch to the smart room is a similar experience. Currently, Low-e is used in some sunrooms. Researchers tested the blocking of ultraviolet rays and near-infrared radiation by glass coated with nano-tungsten dioxide coating, Low e glass, glasses with heat-insulating films, hollow tempered and single-sided Glass. The glass coated with nano-tungsten dioxide has a 91% infrared blockage rate; the 91% ultraviolet blockage rate. 2. Low-e glass has an infrared blocking percentage of 62.8% and a UV blocking percentage of 56%. 3. The infrared blocking percentage of glass with heat-insulating films is 59%, while the ultraviolet blocking percentage is 99.7%. 4. Hollow tempered glasses have an infrared-blocking rate of 34.2%, and an ultraviolet-blocking rate of 23.5%. 5. The infrared blocking percentage of single-sided glasses is 12.4%, and the ultraviolet blocking percentage is 13.5%.

As can be seen by the data, single-sided tempered glass with nano tungsten oxide coating has the best infrared blocking ability. Single-sided tempered glass with thermal film and nano tungsten oxide have the best ultraviolet blocking ability. Coated single-sided glass. Nevertheless, industry insiders say that because UV light has a bactericidal effect, and most people want to take pictures of the sun, a high UV block rate isn't healthy. It is well-known that solar radiation supplies energy to all human activities on Earth. The amount of infrared, ultraviolet, and other rays that are present in sunlight is important. In general, the scientifically-recommended permeability rate is around 10%. In terms of health and energy savings, using nano-tungsten oxide coated insulation glass is the most effective.

It is clear that tungsten oxide is a transparent insulation material with two issues to solve urgently when building energy-saving windows: Transparency is defined as the ability to transmit light. It also meets the lighting requirements. High barrier for the near infrared. This reduces the energy consumed by blocking the radiant energy from the sun.
In addition, this transparent heat insulating tungsten-oxide material is an environmentally friendly, water-based material that can be painted to a thickness as low as a few nanometers. This allows it to enjoy the "warm winter" and the "cool summer" effects without having to open the air conditioner. The tungsten oxide transparent heat insulating material is also a great option for insulation. . These materials include tungsten bronze as well as ITO, ATO FTO.
Tungsten-oxide insulation is not an "evil technology", but rather a result of technological and scientific development. According to the author, in today's advocacy for "energy conservation and emission reduction" as well as "taking a path towards sustainable development", these transparent insulation materials will receive more and greater attention.
