Charges that challenge scientists!

Rub a ruler with a wool and hold it towards paper bits, then you’d find the ruler attracts papers. This may sound a common sense to you – the two surfaces have opposite charges.
But now, researchers find that not all materials behave the same and the reason is still a mystery.
Let’s take a look at the charges that challenges scientists!

GRID SCALE ENERGY STORAGE: A NEW MANGANESE-HYDROGEN BATTERY

For solar and wind to be viable technologies, large scale and cost effective batteries are sorely needed. Now, researchers have made a totally new type of battery, based on cheap manganese sulfate, that fits this bill. Their large proof-of-concept proptoype battery reached ~97% and powered a blue LED for hours!

How to Prevent Cannibalism in Catalysts

This work describes an approach to prevent self assimilation of catalysts to increase their lifetime. It also finds a Hammett correlation between different substituents present on the catalysts and the rate of catalysis in both homogeneous and heterogeneous phase.

Structure-Function Relationship in a Highly Efficient CO2 Reducing MOF

A structure-function relationship has been established for a cobalt containing Metal Organic Framework (MOF) that catalyzes carbon dioxide reduction very efficiently. It has been established that the hydroxyl groups coordinated to the metal co-operates to enhance the catalysis by forming H-bond network with CO2. Let’s learn how the authors performed a systematic and thorough investigation on these MOFs.

Designing and Understanding New Semiconductor Crystals

Solar panels are expensive because of the high-purity silicon present in them. A new material called perovskite rivals the solar conversion efficiency of silicon, but at a fraction of the cost. There is however still a lot of fundamental understanding to be done on perovskites, which these researchers do by studying analogous structures.

Looking inside your TV

Ever wondered how the images on your TV or computer screen are formed? Today let’s look inside your TV and learn about the nanoparticles forming the high definition display! (Obviously without slicing it open!)
