Aerosol particles are among the many materials whose chemical and mechanical properties cannot be fully measured until scientists develop a better method of studying materials at the microscale as well as the much smaller nanoscale (1 nm is one-billionth of a meter). Scientists have now developed such a method and utilized it to perform noninvasive chemical imaging of a variety of materials, as well as mechanical mapping with a spatial resolution of 10 nanometers.

Spinning plant waste into carbon fiber for cars, planes

Added: 23.08.2017 9:09 | 0 views | 0 comments

#zrodlo

Using plants and trees to make products such as paper or ethanol leaves behind a residue called lignin. That leftover lignin isn't good for much and often gets burned or tossed into landfills. Now, researchers report transforming lignin into carbon fiber to produce a lower-cost material strong enough to build car or aircraft parts.

Bond dissociation energies for transition metal silicides accurately determined

Added: 22.08.2017 15:27 | 0 views | 0 comments

#zrodlo

Transition metal silicides are promising for future developments in electronic devices, but fundamental aspects of the chemical bonding between their transition metal atoms and silicon remain poorly understood. One of the most important, but poorly known, properties is the strength of these bonds -- the thermochemical bond dissociation energy.

Quantum physics teaches us that unobserved particles may propagate through space like waves. This is philosophically intriguing and of technological relevance: a research team has demonstrated that combining experimental quantum interferometry with quantum chemistry allows deriving information about optical and electronic properties of biomolecules, here exemplified with a set of vitamins.

Cyborg bacteria outperform plants when turning sunlight into useful compounds

Added: 22.08.2017 9:22 | 0 views | 0 comments


Photosynthesis provides energy for the vast majority of life on Earth. But chlorophyll, the green pigment that plants use to harvest sunlight, is relatively inefficient. To enable humans to capture more of the sun's energy, scientists have taught bacteria to cover themselves in tiny, highly efficient solar panels to produce useful compounds.

Imagine you're on your way to Mars, and you lose a crucial tool during a spacewalk. Not to worry, you'll simply re-enter your spacecraft and use some microorganisms to convert your urine and exhaled carbon dioxide into chemicals to make a new tool. That's one goal of scientists developing ways to make long space trips feasible.

Systematically studying slippery surfaces

Polymer brushes are polymers grown on surfaces, and are attractive for use in lubrication and anti-fouling applications. Researchers varied the length of the chain separating negatively and positively charged functional groups in polymer brushes to investigate how chain length affected the interaction of the polymer brushes with water. They found that the chain length influenced the ionic strength sensitivity for the hydration of the polymer brushes in water but not their water uptake or hydration structure.
