Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

A Miniaturized Autonomous Thermomagnetic Generator
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

Advancing Human Skin Equivalents: The Crucial Role of Neurovascular Integration
This review discusses the importance of integrating vascular and peripheral nerve systems into human skin equivalents (HSEs) to better recapitulate native skin physiology. Recent advances in vascularized, innervated, and neurovascularized HSEs are highlighted, together with emerging bioengineering strategies, current challenges, and future ...
