Nanocrystals that eradicate bacteria biofilm

IMAGE: Schematic diagram showing removal of bacterial biofilm via Mtex view more  Credit: POSTECH The COVID-19 pandemic is raising fears of new pathogens such as new viruses or drug-resistant bacteria. To this, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials. A […]

Mechanophores: Making polymer crystallization processes crystal clear

In modern times, manufacturers produce highly specialized materials for a wide array of uses, called polymers. Polymers have a variety of purposes owing to their versatile properties, ranging from being used in construction due to their high tensile strength and resistance to manufacturing plastic bags that require more lightweight, flexible materials, such as nylon or […]

Researchers measure, model desalination membranes to maximize flow, clean more water

IMAGE: This 3D model of a polymer desalination membrane shows water flow — the silver channels, moving from top to bottom — avoiding dense spots in the membrane and slowing flow. view more  Credit: Image by the Ganapathysubramanian research group/Iowa State University and Gregory Foss/Texas Advanced Computing Center. AMES, Iowa – Nature has figured out how […]

Electrons hop to it on twisted molecular wires

This work may lead to carbon-based electronic devices that require fewer toxic materials or harsh […]

Order and disorder in crystalline ice explained

A fascinating substance with unique properties, ice has intrigued humans since time immemorial. Unlike most other materials, ice at very low temperature is not as ordered as it could be. A collaboration between the Scuola Internazionale Superiore di Studi Avanzati (SISSA), the Abdus Salam International Centre for Theoretical Physics (ICTP), the Institute of Physics Rosario […]

TPU chemists convert plastic bottle waste into insecticide sorbent

Scientists of Tomsk Polytechnic University proposed a method to create a sorbent for imidacloprid insecticide removal from water. The sorbent belongs to metal-organic frameworks, a class of non-conventional materials. The TPU chemists grew such a framework right on polyethylene terephthalate (PET) used to produce regular plastic bottles. The method is quite simple and allows converting […]

Scientists develop an efficient way to produce low-cost heatsinks

NUST MISIS scientists found a way to reduce the cost of industrial and electronics heatsinks production up to 10 times. Consequently, the product itself would also cost less. The proposed methods presume the use of rubbers and silicon carbide as components, i.e. these components are mixed, pressed and sintered. The article on the research is […]

Pulp succeeded in diet? Determining the slenderization of wood pulp

IMAGE: Pixel-resolved distribution analysis shows that the optical retardation decreases with increasing degree of pulp fibrillation. view more  Credit: Osaka University Osaka, Japan – Researchers from the Institute of Scientific and Industrial Research at Osaka University have devised a new method to determine the degree of fibrillation in wood pulp. By taking advantage of the intrinsic […]

Reversible stickiness is something to smile about

IMAGE: To facilitate the debonding of dental restorative materials adhered on tooth surfaces, UV light-embrittled dental resin cement containing photodegradable polyrotacane (PRX) cross-linkers was developed. PRX is a supramolecular interlocked polymer… view more  Credit: Department of Organic Biomaterials,TMDU Tokyo Medical and Dental University (TMDU) researchers report a cross-linker for dental cement that breaks down under UV […]
