From April the French government will reduce fuel taxes slightly to ease the burden on consumers. 

Warned of possible energy shortages in France by the end of the year and called on the French to conserve electricity and gas from now on, saying that if nothing was done, The energy situation will be tough this winter. Some experts say that there are two main reasons for France's energy crisis: first, the conflict between Russia and Ukraine affected the gas market and caused supply tension; The second is a safety review of France's newest nuclear power plant, which may lead to a reduction in output this year. In order to alleviate the energy crisis, the whole French society needs to be mobilized, whether it is the industrial sector, the tertiary sector or every French citizen. Now it is urgent. Rising fuel prices may also have an impact on shipments of the MgB2 powder. 

Introduction to Magnesium Boride MgB2 Powder
Magnesium diboride or magnesium boride, chemical formula MgB2, is an ionic compound with a hexagonal crystal structure.
It is an intercalated compound with alternating layers of magnesium and boron. The magnesium atomic layer has a triangular structure, and the boron atomic layer has a regular hexagonal honeycomb structure, which is similar to graphite.
Magnesium diboride is a hard and brittle substance with poor ductility.
 
Superconductivity of Magnesium Diboride MgB2 Powder
Researchers discovered in 2001 that the seemingly unremarkable magnesium boride turns into a superconductor at temperatures slightly closer to the absolute temperature of 40K (-233 ° C). Its transition temperature is almost twice that of other similar superconductors, and its actual operating temperature is 20 to 30K. The temperature can be cooled by liquid neon, liquid hydrogen, or a closed circulating freezer. These methods are simple and cost-effective compared to industrial cooling of niobium alloys (4K) with liquid helium.
Once doped with carbon or other impurities, magnesium boride is even better than niobium alloys at maintaining superconductivity in the presence of a magnetic field or current. Potential applications include superconducting magnets, power transmission lines, and sensitive magnetic field detectors.

Applications of Magnesium Boride MgB2 Powder
Superconductors:
Superconducting properties and low cost make magnesium diboride attractive in a variety of applications. For these applications, MgB2 powder is compressed into the wire with silver metal (or 316 stainless steel), sometimes through a powder in tube process to make tapes.
Thin coatings can be used in superconducting rf cavities to minimize energy loss and reduce the inefficiency of liquid helium cooling niobium cavities. 
Due to the low cost of its components, MgB2 is expected to be used in superconducting medium and low field magnets, motors and generators, fault current limiters and current leads.
 
Propellants, explosives, fireworks: 
Unlike the element boron, which burns incompletely through a glassy oxide layer that impedes oxygen diffusion, magnesium diboride burns completely when ignited in oxygen or in a mixture with an oxidant. Therefore, magnesium boride has been proposed as a ramjet fuel. In addition, the use of MgB2 in explosive-enhanced explosives and propellants has been proposed for the same reason. It was recently demonstrated that decoy flares containing magnesium diboride/PTFE/FLUORO rubber improved spectral efficiency by 30-60% compared to classic magnesium/Teflon/fluororubber (MTV) payloads. The application of magnesium diboride in rocket propulsion was also studied, where the compound was mixed in paraffin fuel particles to improve mechanical properties and combustion characteristics.

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 MgB2 powder are estimated to be influenced by international political situation changes.
