Roche and its subsidiary TIB Molbiol have developed a series of tests for the detection of the monkeypox virus, the Switzerland-based pharmaceutical company announced.
The monkeypox virus is a close relative of the smallpox virus, belonging to orthpoxviridae in the poxviridae family.
The modular virus detection tool, called LightMix, includes three orthpoxvirus detection kits with different functions, Roche said in a statement. The first kit detects orthpoxvirus; The second kit tests only for monkeypox virus (west and Central African branches); The third kit contains the main functions of the first two kits, showing specific information on the presence of the monkeypox virus (west and Central African branches) as well as the detection of orpoxvirus.
Thomas Schinek, a Roche executive, said the new test could detect monkeypox and help track its spread. Such diagnostic tools are critical for addressing and ultimately managing emerging public health challenges, as they advance responses such as tracking efforts and treatment strategies.
The monkeypox virus was first identified in 1958 in a group of monkeys used for research when the animals developed a "pox-like" infection, hence the name. Since May, several non-endemic countries have reported human cases of the monkeypox virus, including the United Kingdom, the United States, Portugal, Spain, and Italy.
Affected by the ever-changing international situation, the supply and prices of international bulk amorphous boron powder are still very uncertain.
What is boron?
Boron is a chemical element with the symbol B and atomic number 5. In its crystalline form, it is a fragile, dark, shiny quasi metal. Its amorphous form is a brown powder. As the lightest element in the boron family, it has three valence electrons that can form covalent bonds to produce compounds as diverse as boric acid, mineral sodium borate, and super hard crystals of boron carbide and boron nitride.
What is the use of boron?
1. Both crystalline boron and boron oxide are hard. The former is used to make cutting tools and drill bits, and the latter is used to make artificial gems.
2. Boron is known as the "vitamin of metal materials". It can replace molybdenum, chromium, nickel, and other precious metals to make stainless steel when adding a few parts of boron into the molten steel during steelmaking, and it has better strength and excellent mechanical properties. The conductivity of copper or aluminum can be improved by adding a few parts per million of boron to the molten solution.
3. Metal boride-based ceramics, used for making rocket nozzles, high-temperature bearings, high-temperature electrodes, and electrical contacts.
4. Elemental boron is a highly efficient neutron absorber in the atomic energy industry. Boron fluoride is used to make counters in nuclear reactors, and boron is mixed into the aluminum alloy to make neutron shielding material. Borane can be used as rocket fuel in the space industry, and triethyl boron as rocket propellant.
5. Ndfeb magnetic material is used to make computer disk drives, motors for office automation equipment, video cameras, video recorders, and other audio-visual equipment, as well as audio speakers and magnetic resonance imaging systems for medical use.
6. Boron carbide and boron nitride can be used to produce ceramics and ceramic fibers with high-temperature resistance and corrosion resistance, which are used in aerospace and automotive industries, as well as processing gems, and cutting tools, bearings, sandblasting nozzles, and bulletproof materials. Fiber insulation materials made of zinc borate can be used as a fire retardant, bleaching, and mordant.
7. Boron is an essential element for plant growth, flowering, and fruiting. Lack of boron in the soil, the formation of leguminous rhizobia will be difficult, flax, hemp, alfalfa, and other crops will stop growing, and beetroot rot, cotton bolls, and sunflower withered; In addition, boron is also an indispensable element in human bones. Proper intake of boron can reduce blood lipid, inflammation, anticoagulation, and anti-tumor, especially can reduce the incidence of prostate cancer.
Is boron the same as borax?
Boron is a chemical element with the symbol B and atomic number 5. And borax is an inorganic compound, chemical formula is Na2B4O7·10H2O. So, the main difference is that boron is a chemical element, and borax is a chemical element, a compound. In addition, boron's melting and boiling points are 2076 °C and 3927 °C, respectively. Borax, on the other hand, has melting and boiling points of 743 °C and 1,575 °C, respectively.
How do you use boron powder on plants?
Boron is an essential micronutrient for healthy plant and agricultural growth and development. The importance of boron has proved crucial in plant production since the early 1920s. Low concentrations of borate are used in agriculture as micronutrients in fertilizers.
What is amorphous boron powder?
Boron can be divided into crystalline boron and amorphous boron:
Crystal boron is black gray, high hardness, similar to diamond hardness, it is commonly used to replace diamond to manufacture cutting tools or drills. Its conductivity is poor, but it increases with temperature, showing a difference from that of a metal conductor.
The chemical properties of amorphous boron are more active than those of crystalline boron. Crystalline boron is quite stable at room temperature, can only react with fluorine, and can only react with nitrogen, oxygen, chlorine, sulfur, bromine, iodine, and other non-metallic elements at high temperatures. Amorphous boron is relatively active, slowly oxidized in air, and almost reacts with most metal elements at high temperatures to form non-integral borides. It reacts with water vapor under red heat to produce metaborate acid and hydrogen.
What is amorphous boron powder used for?
Amorphous boron powder is a kind of important energy material, in a composite solid propellant as a solid fuel, the calorific value of the boron is twice as tall as carbon above, is about 2 times of aluminum, magnesium, more than 2 times, its volume is almost three times the hydrocarbon fuel heating value, density is only slightly lower than aluminum, with the highest volume calorific value, in terms of its energy, boron should be the best fuel, not of metal. The ignition temperature of amorphous boron decreases greatly because of its irregular shape and large specific surface area.
Amorphous boron powder Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled amorphous boron powder are estimated to be influenced by international political situation changes.
