Cumulative‐Stress‐Resilient Microelectromechanical Switches for Extreme Environment Applications

Advanced Electronic Materials, EarlyView.
A microelectromechanical switch combines a thermomechanically stable suspended structure with radiation‐tolerant materials to preserve operation under cumulative shock (2900 g), vibration (2000 Hz), gamma irradiation (1 Mrad), extreme temperatures (4–450 K), and proton irradiation (100 MeV, 1012 p/cm2).

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

Advanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Surface‐Strained NiMo Cathodes Enable Kinetics‐Decoupled Hydrogen Bubble Management for Stable Near‐Neutral Water Electrolysis

Advanced Energy Materials, EarlyView.
Surface strain tunes the NiMo/electrolyte interface without altering intrinsic hydrogen evolution reaction (HER) kinetics. The strained surface exhibits a lower effective bubble‐detachment tendency and faster release of smaller H2 bubbles, sustaining a more accessible catalytic interface in near‐neutral electrolyte. Reduced bubble‐induced transport and

Kelvin Watt Balance (No. 460)

This is one of a set of four Kelvin balances purchased by the National Bureau of Standards at the end of 1902. It has a linear fixed scale 0-650. With a current of 110 volts, a 500 ohm multiplier was used in the moving coil circuit.

Hybrid Two‐Step Inkjet Printing and Dip‐Coating Enable Scalable 30%‐Efficient Perovskite/Silicon Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Adopting a scalable hybrid two‐step deposition process route, textured perovskite/silicon tandem solar cells achieve over 30% power‐conversion efficiency. The process route replaces all non‐scalable spin‐coating steps, including organic precursor deposition, self‐assembled monolayer formation, and passivation layer deposition, with scalable techniques ...

Trash to Treasure: PFAS‐Functionalized MOFs for Boosted Piezocatalytic H2 Production

Advanced Energy Materials, EarlyView.
A novel pollutant‐as‐functional‐additive strategy is developed via postsynthetic modification of MOF‐808(Hf) with perfluorohexanoic acid (PFHxA), a typical PFAS pollutant. The modification boosts the dipole moment of the MOFs, enhances their piezoelectricity to promote efficient electron‐hole separation, thus delivering ultrahigh piezocatalytic ...
