Cooking spoons, spatulas or whisks: polyamide (PA) kitchen utensils provide valuable baking, roasting and cooking assistance. However, components of this plastic can migrate from the utensils into the food and consequently be ingested by consumers.
By creating protocells in hot, alkaline seawater, a UCL-led research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools, in a new study published in Nature Ecology & Evolution.
Biomedical engineers from Duke University have demonstrated that they can create stable materials from engineered disordered proteins by altering the environmental triggers that cause them to undergo phase transitions. This discovery shines a light on previously unexplored behaviors of disordered proteins and allows researchers to create novel materials for applications in drug delivery, tissue engineering, regenerative medicine and biotechnology.
University of Tokyo researchers used a rotary evaporator to coax non-chiral molecules to form supermolecules of a specific helicity. This work may be used to synthesize cheaper pharmaceuticals, and also explain how the handedness of biomolecules originated.
Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell. Crystal misorientation creates small-scale defects in the grain structure, which interrupt the transport of electrons within the solar cell and lead to heat loss.
Nanocontainer for drugs can have their pitfalls: If they are too heavily loaded, they will only dissolve poorly. Why this happens is now reported by a Würzburg research group in "Angewandte Chemie".
The ultrathin films are able to be injected using minimally-invasive syringe needles and can be used as a platform to deliver molecular and cellular drugs. The use of shape-memory polymer also enables unprecedented temperature-dependent control to allow for adhesion and removal of the nanosheets on biological surfaces.
From tires to clothes to shampoo, many ubiquitous products are made with polymers, large chain-like molecules made of smaller sub-units, called monomers, bonded together. Now, a team of researchers from UD and UPenn has created a new fundamental unit of polymers that could usher in a new era of materials discovery.
A University of Arizona team created the next generation of long-wave infrared plastic lenses. The plastic, a sulfur-based polymer forged from waste generated by refining fossil fuels, is incredibly useful for lenses, window and other devices requiring transmission of infrared light, or IR, which makes heat visible. The new lens material could make IR cameras and sensor devices more accessible to consumers.
Researchers at the Laboratory of Organic Electronics, Linkoping University, have discovered a material that can both increase and reduce its volume when exposed to a weak electrical pulse. In a sponge, or filter, the researchers can control the size of particles that pass through.
