Points You Should Remember About Covalent Bonds
A covalent bond is a chemical bond that involves sharing of pairs of electronsbetween atoms. These pairs of electrons are known as bonding pairs or shared pair. Covalent bond is also known as molecular bond. Covalent bonding arises between two atoms of the same element, or of elements which are close to each other in the periodic table. Covalent bonding occurs primarily between non-metals. Read more.
A University of British Columbia (UBC) researcher is suggesting the types of cooking oils people consume may be sabotaging their efforts to stay healthy and avoid illnesses such as diabetes. Sanjoy Ghosh, a Michael Smith Health Research Foundation Scholar and a professor at UBC’s Okanagan campus, has recently published research that concludes a high consumption of polyunsaturated fatty acids (PUFA) but not monounsaturated fatty acids (MUFA).

Water is life. Kirloskar Brothers Ltd expounds on various technologies it has adapted to recycle and reuse water/wastewater – essentially, making this scarce resource go the extra mile. The importance of water in all aspects of life is not lost on anyone, least of all, on India’s rapidly developing industry.This has, in turn, affected the growth of the water industry. Growing urbanisation and industrialisation, coupled with over-exploitation of water. Read more.
(XOM) said that it has discovered additional oil in the Payara reservoir offshore Guyana
, increasing the total Payara discovery to approximately 500 million oil-equivalent barrels. These positive well results increase the estimated gross recoverable resource for the Stabroek Block to between 2.25 billion oil-equivalent barrels and 2.75 billion oil-equivalent barrels. Read more.
7 few quick facts about Argon Gas
Argon is the 3rd noble gas, in period 8(p-block) of Periodic table, it makes up about 1 per cent of the Earth’s atmosphere. The solubility of Argon is approximately the same solubility as oxygen has. It is 2.5 times as soluble as nitrogen in water. The name “argon” is derived from the Greek word ?ργ?ν, meaning “lazy” or “inactive”. Read more
Understanding how oil and gas molecules, water and rocks interact at the nanoscale will help make extraction of hydrocarbons through hydraulic fracturing more efficient, according to Rice University researchers. Rice engineers George Hirasaki and Walter Chapman are leading an effort to better characterise the contents of organic shale by combining standard nuclear magnetic resonanceNMR) he same technology used by hospitals.

Carbon is the 15th most plentiful element on the Earth’s crustand is abundant in the Sun, stars, comets, and in atmospheres of most of the planets. It is a soft element and dull grey or black in color. Its name is derived from a Latin word “carbo” which means “charcoal”. Read more.
The growth of the global surface and fire protection coatings market looks promising as more and more consumers are preferring these coatings as opposed to conventional paints. Although the market for surface and fire protection coatings is niche, there lies tremendous opportunity in this market owing to the effectiveness of these coatings and the wide range of surfaces on which they can be applied to, according to a report by Market Research.

The global silicone sealants market size was estimated at over 550 kilo tonnes in 2015 and is likely to exceed 820 kilo tonnes by 2023 and is expected to grow at over 4.5% from 2016 to 2023, according to a new report by Global Market Insights Inc. Properties such as excellent thermal & weather stability, oxidation & ozone resistance, physiological inertness, high gas permeability and extremely low-temperature flexibility favour silicone sealants Read more
Scientists from Tomsk Polytechnic University (TPU) are developing a technology for fuel production from coal processing wastes. This fuel is ten times more environmentally friendly that will make it possible to resolve two problems at once: to reduce the amount of anthropogenic emissions of TPSs and efficiently dispose wastes from coal processing and beneficiation.
