3+ hour, 31+ min ago   (286+ words) Since the discovery of mechanical graphene exfoliation in 2004 and subsequent investigations into Gr/Al composites, considerable effort has been devoted to synthesizing these composites at the nanoscale. The review synthesizes over a decade of research, emphasizing the pivotal role of…...

2+ hour, 19+ min ago   (148+ words) From flexible electrodes to biodegradable architectures, researchers are redesigning battery materials so that electrochemical reactions can do far more than supply power. Electrical stimulation can support wound healing, nerve regeneration, and bone repair. It can guide cell migration, promote Schwann-cell…...

17+ hour, 41+ min ago   (278+ words) Non-physicists might hear of 'the Hall effect' and think it relates to the way time elongates when trying to get young children out of the front door, or the phenomenon where you always forget your keys or phone as you…...

16+ min ago   (94+ words) Magnesium is one of the most familiar elements in the world, best known for burning with a blinding white flame and for its role in lightweight alloys. Yet at the nanoscale, magnesium behaves in ways that bulk metal never could....

28+ min ago   (75+ words) Every year, hundreds of millions of lithium-ion batteries reach the end of their working lives, and most of the valuable materials locked inside them are never recovered. At the same time, factories, paint shops and refineries continue to pump volatile…...

1+ hour, 17+ min ago   (504+ words) Defects in metal oxides have long been treated as a single, undifferentiated class of active sites, but a new study suggests that the fine print matters enormously....

1+ hour, 52+ min ago   (29+ words) Most rechargeable batteries depend on lithium, but researchers and manufacturers are also developing batteries that use sodium. Sodium is widely …...

2+ week, 6+ day ago   (252+ words) Biomechanics is the scientific study of the mechanics of living structures, or of non-living structures such as silk or nacre that are produced by organisms. The recently extinct thylacine was Australia’s largest marsupial predator and famously likened to dog-family carnivorans…...

2+ hour, 10+ min ago   (54+ words) X-ray imaging has long promised a tantalizing goal: the ability to peer inside intact, three-dimensional objects at nanometre resolution without slicing, staining, or otherwise destroying them. A newly reported advance in lensless holotomography moves that promise substantially closer to routine…...

3+ hour, 32+ min ago   (56+ words) A team of researchers at Tianjin University has developed a scalable process that converts the mycelium of the filamentous fungus Aspergillus niger into partially deacetylated chitin–glucan complex nanofibers, a renewable bionanomaterial with potent antibacterial activity and remarkable mechanical performance....
