Identifying reliable and sustainable sources of electricity is a significant challenge the present time. However, most energy-generation mechanisms produce unavoidable low-grade waste heat as byproduct while harvesting (or converting) electrical energy from conventional or renewable sources. Each year, over 60% primary wasted heat. Accordingly, considerable efforts are being made to convert this into usable using diverse conversion materials. In review, three actively investigated beyond...

Optimization of the formulation and processability 3D-printable ceramic polymer composites offers a solution to piezoelectric materials with high printability responses. Our approach is based on both composite auxetic structural design. The optimal exhibited strong interfacial adhesion, dispersion stability, low viscosity, smooth surface, resulting in piezoelectricity. In addition, processing parameters, such as intensity application time UV laser, were optimized for processability....
Acoustic energy transfer using ferroelectrically augmented triboelectric receivers can efficiently deliver to implantable medical devices, marine cable operation sensors, and electronic devices with electromagnetic interference shielding cases.
Abstract Despite the rapid development of various wearable generators to harvest energy from human activity, they are limited single or intermittent power generation. Here, stretchable and washable harvesting fabric is reported, which enables biomechanical biochemical generation through co‐weaving triboelectric generator (TEG) perspiration electric (PEG)‐based fibers. The two approaches can work individually simultaneously, thereby combating humidity increasing electrical output. maximum...
2D transition metal dichalcogenides (TMDs) have significant research interests in various novel applications due to their intriguing physicochemical properties. Notably, one of the TMDs, SnS
Herein, an ultrafast flash lamp-driven photothermal design strategy delivers optimal atomically mixed catalysts on a 3D nanostructured metal oxide system. The photocatalytic activity demonstrates selective chemical detection at room temperature and environmental remediation.
Hybrid energy harvesters, using multiple harvesting mechanisms, have been proposed to overcome the limitations of single-mode harvesters. However, since most hybrid harvesters merely combined generated by each mechanism, they could not synergistically enhance output beyond a simple additive approach. In particular, although thermoelectric-piezoelectric explored for simultaneously utilizing ambient thermal–mechanical flows, conventional design achieve expected sum separately harnessed...
Mutation of SLC26A4 is the most common cause prelingual hearing loss in East Asia. Patients with mutations have variable phenotypes ranging from non‐syndromic to Pendred syndrome. Here, we analyzed correlation between genotype and various inner ear found a possible underlying mechanism. This study included 111 patients bi‐allelic who had bilateral enlarged vestibular aqueduct (EVA) loss. p. H723R (61%), c.919‐ 2A >G (24%), T410M (4%) were Korean EVAs. Residual or was better than that...
We investigated potential protein markers of post-mortem interval (PMI) using rat kidney and psoas muscle. Tissue samples were taken at 12 h intervals for up to 96 after death by suffocation. Expression levels eight soluble proteins analyzed Western blotting. Degradation patterns selected clearly divided into three groups: short-term, mid-term, long-term PMI based on the half maximum intensity intact expression. In kidney, glycogen synthase (GS) kinase-3β degraded completely within 48 making...
