  • Amorphous boron powder (ABP) has a comparative edge over conventional fuels like aluminum, magnesium, etc., owing to its high heat of combustion for use in fuel-rich propellants for integrated rocket ramjets. The low atomic weight, high heat output, ready ignitability with KNO, releasing large amounts of heat, and persistent burning even at low-pressure2 make boron-based pyrotechnic composition a beautiful igniter. High Energy Materials Research Laboratory, Pune, has established a process for pr Boron Carbide has the highest hardness of any material.

Can I sprinkle borax around my house

When applied around the foundation of your house, borax will keep ants and spiders from entering your home. Sprinkle it on the weeds and vegetation in the driveway, walkway and sidewalk cracks. Caution: Borax is toxic to plants, so only sprinkle it on the vegetation you want to kill. Typical symptoms of toxicity from exposure to excess Boron or other ions are yellowing of leaf margins and tips and sometimes between veins. Symptoms progress to necrosis (browning) and premature drop of foliage. Re

Valleytronics of Molybdenum disulfide

Due to the lack of spatial inversion symmetry, odd-layer MoS2 is a promising material for valleytronics because both the CBM and VBM have two energy-degenerate valleys at the corners of the first Brillouin zone, providing an exciting opportunity to store the information of 0s and 1s at different discrete values of the crystal momentum. The Berry curvature is even under spatial inversion (P) and odd under time reversal (T); the valley Hall effect cannot survive when both P and T symmetries are pr
