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.

Quantum Dot Lasers: Improving Efficiency with Perovskite Shells

Lasers are cool – everyone who’s seen a sci-fi movie knows that. But we still haven’t figured out how to use them to their full potential in real life. This paper explores some ways to improve the efficiency of quantum dot lasers, which have a myriad of applications in computers to cell imaging.

Neutral Water Splitting by Self-Repairing Catalyst

In this work the authors discussed how and why a self-healing mechanism works for their catalyst, as well as how to rationally design other self-healing water oxidation catalysts by better understanding the kinetics of the key catalytic steps.

Using Heat to turn Water into Fuel

The development of clean, efficient, and renewable forms of energy is a critical scientific challenge. Plants have already figured out how to do this via photosynthesis. Can we develop a process that mimics this?

Getting Rid of the Coffee Ring

Explore its implications and challenges in materials industry and learn about a simple approach to get rid of it.

Machine Learning for Understanding Materials Synthesis

Title: Materials Synthesis Insights from Scientific Literature via Text Extraction and Machine Learning Authors:     Edward Kim, Kevin Huang, Adam Saunders, Andrew McCallum, Gerbrand Ceder, and Elsa Olivetti Year: 2017 Journal: Chemistry of Materials The sheer volume of publications makes scientific literature a vast sea of information…

Bicarbonate Controlling the Rate of CO2 Reduction

This work shows that bicarbonate (HCO3-) is neither a general acid nor a reaction partner in the rate-limiting step of electrochemical CO2 reduction catalysis mediated by planar polycrystalline Au surfaces. Kinetic modeling studies and electrochemical experiments suggest that it acts as a proton donor in steps past the rate-limiting one and a buffer in the solution.
