How does melanin protect cells from damaging radiation? How can this ability be improved?
Light-responsive substances are all the rage; find out how one research group invented a new class of photomechanical materials.
Scientists craft a “greener,” copper-iodide-based ink with amazingly efficient photoluminescent properties
Crime scene techs use luminol to reveal latent bloodstains – can normal, visible light increase the reaction’s sensitivity?
What’s in a screen? It might be tiny particles called quantum dots – a novel material for everything from screens to solar cells. But how do researchers optimize new materials like quantum dot films? One type of spectroscopy – called transient absorption – could help.
The controversy over TiO2’s hydrophilic/hydrophobic transition has been examined in new detail – with researchers concluding that atmospheric molecules can attach onto TiO2’s surface, changing its chemical properties.
What will medicine look like 10 years from now? Well, your doctor might be shining a light on you to help target drug delivery in your body. Read more about drug delivery using molecules called photocages inside!
Birds and other migratory animals use the Earth’s weak magnetic field to navigate, but what do they use as a compass? While previous research has uncovered some promising candidates, not until now have experiments identified a compass sensitive to fields as weak as Earth’s – DNA repair by photolyase.
Find out what “photochemical barcodes” are and how they might help us understand complex biological processes.
Ever had your phone die out of nowhere? Wonder how you’re going to charge your Tesla on your next road trip? Researchers from the University of Cambridge have got your back – they’ve developed a single material that doubles as a battery and a solar cell.
Printing is cool, but 3D printing is cooler! Instead of words on a page, you can print spoons and forks and even houses! And today, you’ll see the coolest 3D printing – printing chains of molecules, simply with light!
How can flavin and flavoprotein help with cancer therapy? A very nice example of biorthogonal chemistry and its potential.
Photoredox catalysis is at it again! This time it is used to synthesize polysubstituted aldehydes – highly useful building blocks – from readily available styrenes and vinyl ethers.
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.
Quantum dots are fascinating super small solids. Highly conjugated tetracene is an electronically active organic molecule. When these two are mixed, electrons bounce around in amazing ways and these researchers found out how.
Heating a chemical reaction to accelerate the reaction rate is like setting phasers to kill, it may get the job done but it’s certainly not the most elegant or effective method. What if you could provide just enough energy to break the appropriate bonds and control exact product outcomes without wasting energy?
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.
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.
There are lots of ways to use sunlight to achieve sustainable energy goals. Photocatalysts, which can use sunlight to power useful chemical reactions, are of great interest for the production of solar fuels like hydrogen. Read more about how we can use novel nanomaterials as photocatalysts in this Chembite!
