Electrospun polystyrene shell/polyurethane core fibres made by scientists in China have absorption capacities 2-3 times higher than reported for non-woven polypropylene fibres (widely used to clean up oil spills). Electrospun fibres are an ideal candidate for soaking up oil, as their structure means the oil can fit into the voids between fibres, not just be adsorbed on a surface. The materials are also recyclable, showing comparable oil sorption capacity to polypropylene fibres even after five sorption cycles. Applications could be in oil spill remediation and in removing discarded edible oils from the wastewater system.
Is the simplest chemical reaction really that simple?
Most people think that quantum theory, which describes the motion of molecules and atomic and subatomic particles, is counterintuitive, since quantum mechanics describes behavior at odds with classical mechanics. Even Albert Einstein, who never accepted quantum mechanics, famously said that ... more
Genes of high temperature superconductivity expressed in 3D materials
The problems of high temperature superconductor (HTSC) are important for the physics community and even the whole science area. Ever since its discovery, many researchers have conducted various studies, still lacking of widely accepted solutions. Recently, Prof. Jiangping Hu from Institute ... more
Copper ion unlocks magnesium's potential in next-generation battery
Researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have come a step closer to making a viable, high-output battery based on magnesium (Mg), an element the United States Geological Survey reports is far more abundant ... more
‘Forensic fingers’ for crime scene investigation
A team of scientists in the United States has developed a wearable fingertip sensor to enable crime scene investigators to rapidly detect explosives and gunshot residue. Traditional forensic analysis is typically carried out in a central laboratory, which requires time-consuming processes s ... more
High-performance epoxy resin adhesives from renewable green starting materials
A series of epoxy resins has been synthesised by a team of chemists from Germany, who used renewable starting materials for a more environmentally friendly approach than conventional methods. The resulting epoxy resins have highly desirable mechanical properties, such as high stiffness, tha ... more
Cheap, simple and efficient molybdenum carbide electrocatalysts for hydrogen production
US scientists have made an efficient catalytic system to split water that uses molybdenum carbide nanoparticles on a carbon nanotube support. Molybdenum and carbon are both low cost and abundant elements. Water splitting using sustainable energy sources, such as solar and wind power, has be ... more
Chemical sensing with 2D materials
During the last decade, two-dimensional materials (2DMs) have attracted great attention due to their unique chemical and physical properties, which make them appealing platforms for diverse applications in opto-electronic devices, energy generation and storage, and sensing. Among their vari ... more
Atomic hydrogen interactions with gas-phase coronene cations: hydrogenation versus fragmentation
Sequential hydrogenation of polycyclic aromatic hydrocarbon (PAH) cations drives a gradual transition from a planar to a puckered geometry and from an aromatic to an aliphatic electronic structure. The resulting H-induced weakening of the molecular structure together with the exothermic nat ... more
An intramolecular annulation strategy has been developed for the synthesis of tetrahydrobenzo[e]pyrano[4,3-c][1,2]thiazine derivatives by means of coupling of aldehydes with 2-(4-hydroxybut-1-yn-1-yl)-N-arylsulfonamides using a catalytic amount of silver hexafluoroantimonate in toluene at 8 ... more
