Drop‐Location‐Insensitive Droplet‐Based Electricity Generator Using Polydimethylsiloxane Slippery Covalently Attached Liquid Coatings

Advanced Science, EarlyView.
Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

High‐Power Hybrid Nanogenerator With Multi‐Degree‐of‐Freedom Mechanical Coupling for Harvesting Water Wave Energy

Advanced Science, EarlyView.
A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Designing Tissue Function Through Embedded Bioprinting Architectures

Advanced Science, EarlyView.
Embedded bioprinting enables soft, cell‐dense constructs to be fabricated within supporting bath environments. This review introduces a function‐guided framework linking target tissue functions to architectural requirements, supporting bath selection, bioink design, printing dynamics, and validation assays.

Machine Learning Confirms GW231123 is a “Lite” Intermediate Mass Black Hole Merger

The Astrophysical Journal Letters
The LIGO–Virgo–KAGRA Collaboration recently reported GW231123, a black hole merger with total mass of around 190–265 M _⊙ . This event adds to the growing evidence of “lite” intermediate mass black hole (IMBH) discoveries of postmerger black holes ≳100 M

Periostin‐CCL3 Feedforward Signaling Loop Promotes Cardiac Fibrosis and Cardiomyocyte Necroptosis in Arrhythmogenic Cardiomyopathy

Advanced Science, EarlyView.
POSTN‐CCL3 signaling forms a feed‐forward circuit between cardiomyocytes and cardiac myofibroblasts in arrhythmogenic cardiomyopathy. POSTN activates JNK/RIP3‐dependent necroptotic signaling and JNK/ETS2‐induced CCL3 expression in cardiomyocytes. In turn, CCL3‐CCR5 signaling in cardiac myofibroblasts activates NF‐κB/p65 and promotes POSTN expression ...

Laboratory sources of gravitational waves

Journal of Physics: Conference Series, 2020
Abstract We consider the possibility of generating and subsequently detecting artificial gravitational waves in a laboratory based on different approaches. As one of the methods for creating gravitational waves, we investigate oscillations of the ions of the crystal lattice of a dielectric under the influence of high-power laser ...
