How the building blocks of life may form in space
In a laboratory experiment that mimics astrophysical conditions, with cryogenic temperatures in an ultrahigh vacuum, scientists used an electron gun to irradiate thin sheets of ice covered in basic molecules of methane, ammonia ...
Large surface area lends superpowers to ultra-porous materials
Some materials are special not for what they contain, but for what they don't contain. Such is the case with metal-organic frameworks (MOFs) – ultra-porous structures that are being developed for a variety of future applications ...
Spinning high-strength polymer nanofibers
Spiderman has it figured out.
Why we need erasable MRI scans
Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is through the use of contrast agents—magnetic dyes injected into ...
Cracking the catalytic code
The newly developed ability to tap previously inaccessible shale gas deposits during the last decade has created an abundant source of gases, including methane, ethane and propane, that are used to create chemical-based products ...
Selective catalysts for carbon dioxide recycling
NUS chemists have discovered key factors determining the selectivity of copper (Cu) catalysts for transforming carbon dioxide (CO2) and water into useful chemicals and fuels.
Flavins keep a handy helper in their pocket
In human cells, vitamins often serve as the precursors of cofactors—non-proteins that are an essential part of enzymes. Among them are the flavins, derived from vitamin B2.
Cheaper and easier way found to make plastic semiconductors
Cheap, flexible and sustainable plastic semiconductors will soon be a reality thanks to a breakthrough by chemists at the University of Waterloo.
Silk-based devices with antisense-miRNA therapeutics may enhance bone regeneration
Researchers have incorporated therapeutic microRNAs (miRNAs) into bioresorbable, silk-based medical devices such as screws and plates to achieve local delivery of factors that can improve bone growth and mineralization at ...
