Writing in the journal Materials Today: Proceedings, a team of scientists from Sant Longowal Institute of Engineering and Technology and Chandigarh University in India have investigated the thermal and sonochemical modification of guar gum to enhance the material’s properties and commercial application.
In physics, Schroedinger's cat is an allegory for two of the most awe-inspiring effects of quantum mechanics: entanglement and superposition. Researchers from Dresden and Munich have now observed these behaviors on a much larger scale than that of the smallest of particles.
Thermoelectric devices convert thermal energy into electricity by generating a voltage from the difference in temperature between the hot and cold parts of a device. To better understand how the conversion process occurs at the atomic scale, researchers used neutrons to study single crystals of tin sulfide and tin selenide. They measured changes that were dependent on temperature.
The synthesis and study of radioactive compounds are naturally difficult due to the extreme toxicity of the materials involved, but also because of the cost and scarcity of research isotopes.
???????Solar panels, also known as photovoltaics, rely on semiconductor devices, or solar cells, to convert energy from the sun into electricity.
For the next six months, a camera system on the exterior of the International Space Station (ISS) will be snapping photos of more than a dozen different material samples, gathering detailed information that will help researchers determine how – and why – the harsh conditions of space affect these materials.
Inspired by the way termites build their nests, researchers at Caltech have developed a framework to design new materials that mimic the fundamental rules hidden in nature's growth patterns.
The key to producing better rechargeable lithium batteries could be a little brushing. Chemistry professor James Tour’s lab at Rice University developed a method for fine-tuning the surface of battery anodes by merely brushing particles into them.
Metal parts made using laser-based additive manufacturing (AM) can have residual strain resulting from rapid heating and cooling during printing. Annealing parts after printing reduces the strain but can cause unwanted structural changes. Researchers used neutron diffraction and neutron imaging to measure strain and determine optimal annealing for metal AM parts.
New research from the group of Joshua Yuan, professor and chair of energy, environmental and chemical engineering at Washington University in St. Louis' McKelvey School of Engineering, may soon lead to even lighter, stronger carbon fiber -- and stronger plastics -- all using what is currently a waste product.
