Boron is one of the many elements on the periodic table. Its atomic number is five and its symbol is the letter B. Boron’s atomic weight is 10.811. It is a solid at room temperature. The group number for Boron is 13 and the periodic number for Boron is 2. It is also in the p block. Its element category is a metalloid. Boron came from the Arabic word Buraq and the Persian word Burah, which are both meanings for the material called “Borax.” Boron is a tough element – very hard, and very resistant
Boron: The Best Choice in Alternative Fuel With the way the environment is looking these days it seems that it may be a good idea to raise the price of gasoline by one dollar. With growing concerns about pollution and other toxins in the atmosphere, the industry is forced to look into alternate forms of fuel. This extra tax on gasoline could aid in funding their research. Currently research is being performed on the element boron. It has been found to be more efficient and a generally safer
1. The major goal of this paper is to examine the electronic effects of how substituent groups impact the hydroboration of the substituted styrene molecules. The scientists focused mainly on understanding the positioning in which the boron-hydrogen moiety was added to the carbon-carbon double bond. 2. The purpose of the experiments reported in Table 1 was to determine the reproducibility of the α and β alcohol distribution as a result of the hydroboration of styrene. This was achieved through manipulating
DATIVE DATING Quick Introduction to covalent bonding A covalent bond is a chemical bond formed between two atoms that shares one pair of electrons. The atoms are maintained together since the pair of electrons is attracted to both atoms’ nuclei. In this covalent bond there are two types of covalent bonding. They are single covalent bond and double covalent bond. A single covalent bond is a covalent bond that involves the sharing of one pair of electrons between two atoms. On the other hand, a double
Molybdenum is used in synthesis of ascorbic acid and making the iron available in plant. It also helps Phosphorus metabolism and limits ethane to ethylene in plants. Molybdenum serves as an antidote to plants to have excess in Calcium, Manganese, Zinc, and Boron in plants. Deficiency in molybdenum will shows yellowing and stunting growth of plants. 2.1.18 Zinc in Soil Zinc is one of the most essential element needed for plant to have a balanced and normal growth. It acts as an activator to the enzymes and
Material Science in Tennis Material science is the design and discovery of new materials that emphasis on solids. It is one of the big areas of innovation in technology today and also in the sports engineering that includes tennis and also across many sports. In some classes of sailing, the materials used play an important role in the performance innovation as the boat designs cannot change. Each and every sport is unique as the equipment design and the performance differs. Tennis rackets, a key
Neodymium is used in almost anything powered by electricity. When fused together with Iron and Boron, it is one of the most powerful magnets in the world. These magnets are used to create electricity in wind turbine engines, cause vibrations in a phone, accurately reproduce sound and base, computers, medical equipment, toys, and motors (“Neodymium.” Chemicool). When Neodymium is not put with Iron and Boron it is most commonly used as crystals in lasers for laser hair removal, treat skin cancer, or
Silicon (Si) is the best-known semiconductor. Boron, germanium zinc sulfide, Mercury selenide are some the few of hundreds of semiconductors. Semiconductors also could be found in nature like zinc selenide (ZnS), cuprite (CU2O) and galend (PbS). Semiconductors are classified in numerous ways. They exist as pure elements such as Si, B and compounds such as gallium arsenide. Semiconductors could also be categorized as Elemental, Binary and Ternary. • Elemental Semiconductors: These are single elemental
Sustainable Agricultural Intensification in Pakistan: Challenges and Opportunities Or The challenges and Prospects: Striving towards Sustainable Agricultural Intensification in Pakistan The agriculture of Pakistan constitutes the largest sector of the economy. It accounts for 24% of the Gross Domestic Product (GDP) and it employs around 48.5% of the labor force (Pakistan Bureau of Statistics 2017). About 61.24% population lives in rural areas (World Bank 2016) where directly or indirectly their
INTRODUCTION Nutrient are important for plant growth. These are also called essential elements and required for the plant to complete its life cycle. Nutrients are important for growth and development of crop, promotes vegetative and reproductive growth, provides protection against many devastating pathogens that is responsible for the yield loss in many economically important crop. Sixteen important nutrients are vital for plant growth. These are 1. Macronutrients: These nutrients are required in
Effects of salinity on plants Definition: Salinity is the state of high salt concentration or it can be define as the presence of minerals at high levels in water and soil. For example, there are some cations: Na, K, Mg, Ca and anions: NO3, HCO3, SO4, Cl, which accumulates in soil at high concentration and cause salinity in that soil. Introduction: Salinity is major a biotic factor that reduce growth and yield below optimum level. Salinity is the global issue that results in osmotic stress and reduction

The average human can not live any longer than three days without water. Many of the world’s fresh water sources are running dry or are being contaminated, particularly in developing nations, leaving many without safe water to drink. Only two and a half percent of the Earth’s water is freshwater, and less than one percent is accessible by humans (not tied up in ice caps). This one percent of the Earth’s water supply is expected to sustain a population of over 7 billion people, each needing 2.6

Energy Drinks “the pros and cons of coffee” by Sebastein Stefanov and “Energy Drinks- some pros and mostly cons” by MDHIL Networks these two articles explore the topic that is very controversial today. Whether or not to grab an energy drink or a cup of coffee. more specifically should you be aware of differences between coffee and energy drinks and the effects on your health? These authors have explored the pros and cons between these two caffeinated
Properties of Metalloids Metalloids are elements that share properties of both nonmetals and metals. They usually share physical properties with metals and chemical properties with nonmetals. Although they are not as good at conducting electricity and heat as metals, metalloids can still act as semiconductors; they can act as conductors in the right condition. Metalloids are solid at room temperature and are semiconductive. Being semiconductive means that, in the right conditions, metalloids can
The effect of alloying elements on aluminium alloy sacrificial anode was also studied and it was found that the alloying element which have large potential difference from aluminium resulted in alloys with potentials more anodic than unalloyed aluminium. Mercury, the potential of which differs most greatly from that of aluminium, caused a maximum effect on aluminium potential. Effect of some alloying elements on aluminium alloy as sacrificial anode is given below: 1. Magnesium: The solubility of

These complex metal hydrides have high gravimetric storage capacity than the simple metal hydrides. Nitrogen containing hydrides such as amines or imides, and boron containing hydrides (borohydrides) are the main categories in complex metal hydrides. Lithium imide (Li2NH), magnesium amide (Mg(NH2)2), lithium borohydride (LiBH4) and sodium borohydride (NaBH4) are the actively explored complex metal hydrides for
SECTION III – COMPOSITES Composites are a relatively new area, yet important area for the manufacturing of aircrafts and aeronautics. Composite materials tend to show very high resistance to cyclic stresses (very important in aircrafts) and a good, specific strength and also water resistance, which may become a real threat if aircrafts run into dense could of any kind. However composites tend to be degraded by UV light. But you can counter act this by having them heavily pigmented. Sometimes composites
