Exempel på hur du använder BORON i en mening

• Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.
• As the lightest element of the boron group it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride.
• He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine.
• In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements.
• Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well.
• Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula.
• The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellurium.
• boron hydrides, do not conform to classical electron counting rules and the bonding is described in terms of multi-centered bonds, whereas the interstitial hydrides often involve metallic bonding.
• The boron group are the chemical elements in group 13 of the periodic table, consisting of boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl) and nihonium (Nh).
• Despite being pyroelectric, novel materials such as boron aluminum nitride (BAlN) and boron gallium nitride (BGaN) have zero piezoelectric response for strain along the c-axis at certain compositions, the two properties being closely related.
• The structures of the boron hydride clusters were determined beginning in 1948 with the characterization of decaborane.
• However, arsenic and boron, two potentially toxic elements, have been found in the geothermal water used to generate electricity.
• Due to their extreme reactivity and flammability in air, boron hydrides could not be purified until his development of methods for separation using high-vacuum manifolds around 1912.
• The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
• Two laboratory methods start from boron trichloride with lithium aluminium hydride or from boron trifluoride ether solution with sodium borohydride.
• 5 kt, boron lined shot hole, similar to Dormouse, Mink, Fisher, Raccoon, Packrat, HT-I Linden, HT-II Quay.
• In 1935 they were awarded the Nobel Prize in Chemistry for their discovery of Induced radioactivity, resulting from the creation of short-lived radioisotopes by nuclear transmutation from the bombardment of stable nuclides such as boron, magnesium, and aluminium with alpha particles.
• Layered materials, such as graphene, boron nitride, or transition metal dichalcogenides, have unique electronic properties as bilayer systems and are an active area of current research.
• On February 6, 1937, Brown married Baylen, whom he would later credit with sparking an interest in hydrides of boron that would eventually lead to the work for which he, together with Georg Wittig, would be awarded the Nobel prize in Chemistry in 1979, and the following year received his degree as Ph.
• For his Doctor of Philosophy thesis on "Neutron beam spectrometer studies of boron, cadmium, and the energy distribution from paraffin", written under Dunning's supervision, he built a neutron spectrometer and developed techniques for its use.
