Boron

RSR is a radiation survey robot or in other words detecting radiation levels remotely. RSR uses a boron gallium nitride (BGaN) semiconductor in which the Boron (B) atom acts as a neutron converter. During operation, RSR will find a low-level radiation source while avoiding obstacles. Once the source is found, RSR will announce its presence. Introduction: High levels of radiation can be hazardous to humans. This detector can be used to determine the environmental radiation levels to limit exposure

Contents Under Pressure "Better a diamond with a flaw than a pebble without" (Confucius 1). It is a common belief in today’s day and age that it is better to be something of value that is flawed than to be something of no value that has no flaws. Diamonds are formed from pure carbon, which is one of the most abundant elements on planet Earth, and makes up about 18% of the human body. In fact, all life on earth is carbon based. Even from ancient times diamonds have been sought for their extraordinary

What is nuclear fission? How does it work? What does it have to do with nuclear power plants? These are a few of the many questions asked if one hasn’t ever studied nuclear power or doesn’t know how a power plant works. Nuclear fission is the splitting of atoms, which in nuclear fission is uranium atoms. A neutron is released at a targeted nucleus of uranium-235. Two or three neutrons are released from the target nucleus along with fission products, or other nuclei, as seen in the picture below

This potentially life-saving innovation consists of carbon, nitrogen, boron, and hydrogen (Frazier). Boron is another element capable of stopping radiation particles. Hydrogenated BNNTs are not only effective at stopping radiation but are also able to withstand high heat which is necessary for missions in space (Frazier). Furthermore, the

the security of their property. This general standard of commitment may provoke clearly tricky results. A valid example, it was needed by Petrochem Ltd. to painstakingly analyse the safeguards that were obliged to be brought with the concoction boron tribromide bottles. It was their obligation to characterize how unsafe these jugs can be on the off chance that they interact with water. Their obligation was to oblige with the security measures furthermore make mindful of the same to their customers

Metallic and Covalent Bonding: All matter is composed of building blocks in the form of atoms. Atoms consist of three subatomic particles, protons, neutrons and electrons. Protons are positively charged, neutrons have no charge and together they form the nucleus in the centre of the atom. Electrons are negatively charged and form shells in which they orbit the nucleus. Figure 1 Each shell has a maximum number of electrons it can contain, with the first shell containing up to 2, the second shell

" War on iraq was not justified" The 2003 Iraq War lasted less than three weeks. It began in the early morning hours of March 20, when American missiles struck Baghdad. By April 9, U.S. forces had advanced into Baghdad. By April 15 Iraqi leader Saddam Hussein had vanished, and U.S. and allied officials pronounced the end of major combat operations. Although the war itself was short, arguments over whether it was justified had been made for months and years prior to the attack, and still continue

pristine boranes. Also they found that the mixture can be stabilized, after 2 at 90°C, making the as-obtained solid a potential chemical hydrogen storage material.(Over the range 25–300 °C, it is able to release ca. 11.4 wt% of almost pure H2. And forms boron nitride as the solid residue)

Abstract Microalgae is considered as the third generation biomass. Chlorophyta is the most common type of microalgae and has a huge potential used in many fields. Key word: green algae, food supplement, CO2 fixiation, wastewater treatment, hydrogen production Introduction In the early 1950’s, the world’s population increased dramatically due to the end of World War Ⅱ. The predictions of an insufficient protein supply resulted in a search for new alternative and unconventional sources. Algal
