Shell shuts down Europe’s largest refinery after major fire

Royal Dutch Shell plc said that it has shut down Europe’s largest refinery in Rotterdam, the Netherlands after a fire at a high-voltage electricity switch station.
The fire that broke out at Shell Pernis has been extinguished. Pernis is the largest refinery in Europe with about sixty factories. Part of the refinery remains shut down because the electricity is cut. The fire was caused by short-circuiting in a high voltage station, the company said.
According to a security spokesman, the flames cover a wide area. This is due to the fact that the company flares out gases released by the refining of oil as part of the safety procedure.
There is no indication that harmful substances have been released. However, soot particles are being emitted into the air, it added.
It is not yet known when the entire refinery can be put back into operation.

Monsanto, Atomwise collaborate for new crop protection options

Monsanto Company and Atomwise, a biotechnology company have formed a unique research collaboration to increase the speed and probability of discovering and developing new crop protection products using artificial intelligence.
Atomwise develops artificial intelligence systems for molecular discovery. Through this research collaboration, Atomwise’s groundbreaking AtomNet technology will employ powerful deep learning algorithms and supercomputers to analyse millions of molecules for potential crop protection products.
Instead of the traditional trial-and-error and process of elimination to analyse tens of thousands of molecules, the AtomNet technology aims to streamline the initial phase of discovery by analysing how different molecules interact with one another.
AtomNet accelerates this process using deep learning to predict which molecules could have a positive effect in controlling harmful diseases or insects. The software teaches itself about molecular interactions by identifying patterns, similar to how artificial intelligence learns to recognize images.
Monsanto is the first company in the agriculture industry to partner with Atomwise. This collaboration complements Monsanto’s unique partnered approach to crop protection discovery.
“Discovering new solutions is critical, and this collaboration will help bring much-needed crop protection solutions to farmers faster,” said Jeremy Williams, Monsanto’s agricultural productivity innovations lead.
“By combining Atomwise’s sophisticated artificial intelligence systems with Monsanto’s ability to apply real-world validation through the integration of plant breeding, plant biotechnology, crop protection, ag biologicals and data science platforms, together we can develop technologies that support farmers as they work to grow better harvests, protect their crops and deliver more to society in the face of mounting environmental challenges,” added Williams.

Johnson Matthey develops technology that reduces emissions

Johnson Matthey has developed a new technology that reduces emissions from older buses, enabling people to breathe fresh and cleaner air.
Johnson Matthey's catalysts were installed in one-third of new vehicles worldwide, preventing 40 tonnes of potentially harmful emissions from entering the atmosphere every minute of the day.
Emission control systems, developed by Johnson Matthey and its partners, have already been installed in more than 1,000 London buses to enable them to meet increasingly stringent emissions targets. The process started with the retrofitting of 54 older buses for the London Olympics that were used to ferry passengers between sites.
These catalyst and filter systems are installed in the exhaust system of a vehicle, as close to its engine as possible in order to take advantage of the heat generated. They clean the exhaust the vehicle sends out into the atmosphere. A precious metal catalyst (usually containing platinum and palladium), converts harmful carbon monoxide and hydrocarbons into carbon dioxide and water.

New light-activated catalyst that turns CO2 into fuel

Scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) and Nanyang Technological University (NTU) in Singapore have developed a light-activated material that can chemically convert carbon dioxide (CO2) into carbon monoxide without generating unwanted byproducts.
The achievement marks a significant step forward in developing technology that could help generate fuel and other energy-rich products using a solar-powered catalyst while mitigating levels of a potent greenhouse gas.
When exposed to visible light, the material, a “spongy” nickel organic crystalline structure, converted the CO2 in a reaction chamber exclusively into carbon monoxide(CO) gas, which can be further turned into liquid fuels, solvents, and other useful products.
The research is published in the journal Science Advances.
“We show a near 100 percent selectivity of CO production, with no detection of competing gas products like hydrogen or methane. That’s a big deal. In CO2 reduction, you want to come away with one product, not a mix of different things,” said Haimei Zheng, staff scientist in Berkeley Lab’s materials sciences division and co-corresponding author of the study.
In chemistry, reduction refers to the gain of electrons in a reaction, while oxidation is when an atom loses electrons. Among the well-known examples of CO2 reduction is in photosynthesis, when plants transfer electrons from water to carbon dioxide while creating carbohydrates and oxygen.

Indian scientists use tiny bubbles to draw plastic circuits

Indian scientists have found a way to use micro-bubbles to draw complex plastic circuits with lasers, an advance that may lead to low-cost flexible electronic devices.
Solution-printed electronics is one of the fastest growing areas in the industry primarily due to its very low cost and flexibility, researchers from the Indian Institute of Science Education and Research (IISER) in Kolkata said.
It is mostly based on conducting plastics, that is doped to increase conductivity.
The process of synthesising, doping and designing circuits separately is often complex and time-consuming.
The research was published in the journal of Materials Chemistry C.
For the first time, scientists led by Ayan Banerjee and Soumyajit Roy from IISER Kolkata, have developed a simple and inexpensive technique to simultaneously synthesise and pattern conductive polymers on a glass surface in a matter of minutes.
They exposed a solution of charged metal oxide, known as soft oxometalate (SOM) and organic molecules in a glass chamber to optical tweezers - a tightly focused laser.
Absorbing the beam, oxometalate stuck to the chamber surface to form a microbubble around which the metal oxide and organic molecules assembled themselves to form conductive polymers.

Orion to increase prices for rubber carbon blacks in US

Orion Engineered Carbons SA (OEC) said that it is increasing prices for all rubber carbon blacks sold in US, by five cents (5¢) per pound, effective 1 September.
In addition, Orion announced the stopping of one rubber carbon black production line at its Orange, Texas facility, effective at year end. Orion is taking this action because current price levels of rubber carbon blacks in North America do not adequately address the costs of maintaining this production capacity. The company is assisting affected customers through the appropriate transition plans.
“We are increasing prices in order to continue the substantial investments in our North American rubber black production network essential to sustain safety of supply. This increase in pricing and the investments in production are necessary to ensure our long-term supply capability,” said Chris Erickson, Orion’s vice president, rubber carbon black business line, Americas.

Omega-3 fatty acid stops lupus trigger, but how?

Michigan State University scientists have received a $2.3 million, five-year National Institutes of Health grant to help uncover why an omega-3 fatty acid, known as DHA, is so effective in stopping a known trigger of lupus.
Previous MSU research has shown that consuming DHA, or docosahexaenoic acid, which is found in fatty, cold-water fish, can stop the onset of lupus when the disease is caused by a toxic mineral that’s inhaled and typically found around construction, agriculture and mining sites.
It’s still unclear, though, how the natural fatty substance prevents the disease from forming.
“When lupus is triggered by fine inhalable particles called crystalline silica in the lungs, our earlier research has shown that DHA essentially stopped the activation of the disease,” said James Pestka, a University Distinguished Professor of food science and human nutrition.
He is leading the new study with MSU co-investigators Jack Harkema, a pulmonary pathologist and Jenifer Fenton, a nutritional biochemist.
According to Harkema, the DHA could be changing the way these cells react to the silica in the lungs and somehow stops the immune system from overcompensating and going after healthy cells too.
One theory the researchers have is the DHA could help cells send a signal to the body so it won’t overreact and tell the immune system to attack beyond what’s needed. Another thought is somehow the DHA allows the cells to swallow up and remove the toxic silica from the lungs without dying, preventing any inflammatory signals from being sent throughout the body.

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; but, it can also be witnessed between metals and non-metals. Covalent bonds are most likely to occur, when atoms have similar electro negativities.
History of covalence
The term covalence was first used in 1919 in regards to bonding, by Irving Langmuir in article of “Journal of the American Chemical Society”, titled "The Arrangement of Electrons in Atoms and Molecules". 
However, the idea of covalent bonding could be traced to Gilbert N. Lewis, numeral years before 1919, who in 1916 explained the sharing of electron pairs between atoms.
What are various types of covalent bonds?
There exist three types of covalent bonds which is based upon number of shared electron pairs.
Single covalent bond: Single covalent bonds between two atoms are formed, when there exist a mutual sharing of one electron pair. Single covalent bond is denoted by short single line (----).
Double covalent bond: Single covalent bonds between two atoms are formed when there exist mutual sharing of two electron pairs. Double covalent bond is denoted by short double line (=).
Triple covalent bond: Triple covalent bond is formed, when there is sharing of three electron pairs. This bond is denoted by triple short line. 
Polar covalent bond: When a covalent bond is formed between two different atoms, it is said as polar covalent bond.
Non-polar covalent bond: When a covalent bond is formed between two like atoms, it is said as non-polar covalent bond.
