1+ hour 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…...

16+ hour, 22+ 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…...

33+ 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…...

51+ 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…...

2+ hour, 13+ 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....

8+ hour, 39+ min ago   (681+ words) A battery’s weakest point may lie between its materials. Researchers are investigating how damaged interfaces and lost contact affect its life. A battery material can look impressive in a laboratory and still fail when turned into a working battery. US…...

12+ hour, 36+ min ago   (353+ words) Recently, twisted bilayer photonic crystals (TBPhCs) have been used as moiré-based optical platforms, supporting twist-tunable chiroptical and polarization-dependent responses. A periodic moiré supercell exists only for commensurate twist angles, whereas conventional supercell approaches are not directly applicable to incommensurate structures....

13+ hour, 7+ min ago   (428+ words) The conventional analysis of casing deformation relies on engineering logging, analytical models, or repeated finite element modeling and simulation for different wells or field restricts, which may involve high costs, simplifying assumptions, and low computational efficiency. To improve casing deformation…...

13+ hour, 53+ min ago   (245+ words) Ammonia is a common nitrogenous pollutant frequently detected in surface waters and wastewater effluents, where elevated concentrations can cause eutrophication and pose risks to aquatic ecosystems and water quality. For these reasons, advancing efficient and sustainable ammonia removal technologies remains…...
