1. Engineers devise new process to improve energy efficiency of ethanol production
Description: This article talks about the new distillation process that can improve the efficiency of ethanol production, which is one of the bio-fuel. Apart from being a sustainable source of energy, bio fuels are carbon neutral, which means they release into the environment carbon dioxide that they have consumed for their growth. Thus, production of bio-fuels (ethanol) using this new process can be of great help in keeping the environment clean because of their significant contribution in

2. Solar ‘superflare’ shredded Earth’s ozone
Description: The article debates at the impact of solar superflare on ozone layer. Moreover, it also discusses acid rain and skin cancer that are outcomes of damage to ozone layer. Acid rain is caused due to formation of nitrogen oxides that are formed from ionization. These nitrogen oxides deplete the ozone layer. The article throws the light on the greater impacts of solar superflare as ozone layer is already depleted by CFCs and man-made chemicals.
3. A sweet future for biodiesel
Description: Today when all sciences are involved in extensive research to save energy, this article informs us of research revealing the importance of sugar catalysts that can turn waste vegetable oil into biodiesel. Chemistry of sugar catalysts involves sulphonation of carbonized D- Glucose to turn waste oil into biodiesel. This discovery can help in conservation of energy more economically and effectively as compared to other catalysts like zeolites and zirconia.
4. Evidence for Global Warming
Description: The article discusses the issue of global warming, its measures and evidences together with a clear analysis. Increased carbon dioxide concentration has augmented the greenhouse effect, thus contributing to the increase in atmospheric temperature. All the reasons, results, inferences are supposed to help in finding probable controls that can be acquired to reduce the effects of global warming.
5. Chemical Biology
Description: This article is about the importance and connection of chemistry with biology. From cell organelles (proteins and nucleic acids) to cellular activities, like cell division to genetics involves chemistry. The chemical reactions taking place to run cellular activities and catalysts easing the reactions makes the base of biology. This abstract presents a beautiful picture of chemical biology.
6. Is Your Phone Out of Juice? Biological fuel cell turns drinks into power
Description: The article talks about the use of fuel cells that use living enzymes to produce electricity from sugar. The process is highly dependent upon the metals like platinum that acts as catalysts and involves oxidization of glucose to produce energy. These enzymatic fuel cells may boost up the production of energy, thus filling the energy gap through biodegradable mass-produced power source.
7. Another toxin for the Baltic Sea?
Description: The article talks about the new class of naturally produced marine toxins and their negative impacts on aquatic environment of Baltic Sea. These brominated compounds i.e. polybrominated dibenzo-p-dioxins (PBDDs) are produced by cyanobacteria etc., and are getting accumulated in fishes and other aquatic animals through food chain. PBDDs are normally detected in emissions of vehicles and pose a serious threat to the environment and life. This research on production of PBDDs by marine organisms will help determining the intensity of threat and controls we can take.
8. NASA Studies How Airborne Particles Affect Climate Change
Description: This article talks about the role of aerosol particles in climate change. Aerosol particles are micrometer sized particles that affect atmospheric temperature by changing the flow of radiant energy from the sun to the Earth’s surfaces and within the atmosphere. Particle size and source of aerosol determines their effect on atmosphere. This research will help understand the chemistry of aerosol and their effect on climate change in a better and comprehensive way.
9. The Land of Rising Conservation
Description: The article discusses the invention of new home fuel cells in a wonderful manner. These new home fuel cells convert natural gas into hydrogen which is used to generate electricity and heat released by the process is used to warm water. Thus, without emission of carbon dioxide, it not only helps in avoiding the environmental damage but also energy conservation.
10. Fundamental Ways that could Stop Global Warming
Description: The article talks about the most critical issue i.e. global warming. Though global warming has been existed long before we have been out here, but temperature has increased over thousands of years. Blind consumption of energy, excess release of CFCs from appliances, like air conditioners, has heightened the effects of global warming. The chemicals like CFCs deplete ozone layer and thus cause global warming. The suggestions in this article may help people understand how they can contribute to reduce the global warming and its impacts.
