Association Between Caffeinated Beverage Intake and Semen Quality in a Preconception Cohort

BACKGROUND: Few studies have examined the association between caffeine intake and semen quality among couples attempting conception. OBJECTIVES: To examine the effect of caffeinated beverage intake on semen quality. MATERIALS AND METHODS: We analyzed cross-sectional data from Pre...

Eliminating Texture‐Induced Retention of Self‐Assembled Monolayer Residues for High‐Performance Perovskite Solar Cells

Self-assembled monolayers (SAMs) constitute foundational interfacial elements in high-efficiency inverted perovskite solar cells (PSCs); however, ensuring chemical and electronic integrity across SAM-modified interfaces remains challenging. Although post-deposition solvent washin...

“Brick–Sand–Mortar” Inspired Natural Konjac Glucomannan/BN–OH@AgNP Composite Film with High Thermal Conductivity and Electrical Insulation

Abstract The development of high-performance thermal interface materials (TIMs) that simultaneously achieve efficient thermal transport, mechanical robustness, and electrical insulation remains a major challenge. In this study, a hybrid filler system consisting of silver nanopart...

Regulating Hard Segment Aggregation in Polyurethane Elastomers via Multiple Hydrogen Bonding Motifs for Enhanced Mechanical Properties

Abstract Controlling aggregation of soft and hard segments is a prevalent strategy to improve the mechanical performance of polyurethane elastomers, yet the regulatory actions of hydrogen bonding motifs governing the size and spatial distribution of hard and soft segments remain...

Mixed‐Dimensional 1D/2D Ternary CMOS for High‐Performance Integrated Circuits

ABSTRACT Ternary logic offers a path to higher information density and lower power consumption beyond the limits of binary CMOS, yet its progress has been limited by the absence of high‐performance ternary transistors and scalable circuit technologies. Here we report a mixed‐dime...

Over 7500 Cycles Achieved in Platinum‐Group‐Metal‐Free Ni–H 2 Battery Through Reversible Hydrogen Spillover

ABSTRACT Traditional Ni–H 2 batteries employing platinum‐group metal (PGM) catalysts exhibit ultralong lifetimes (> 10 000 cycles), yet comparable durability has not been achieved in recently developed PGM‐free systems, mainly due to sluggish hydrogen evolution and oxidation reac...

Highly anisotropic nonrelativistic charge-to-spin conversion in altermagnets

The charge-to-spin conversion provides an efficient way to manipulate the magnetization by electrical means. In this work, we report on a study on the anisotropic nonrelativistic charge-to-spin conversion response to the current direction in altermagnets. We prove that the spin c...

Precise Management of n‐Value Distribution at the 2D/3D Interface Enabling Efficient Wide‐Bandgap Perovskite Solar Cells

Introducing a 2D perovskite layer on the surface of 3D perovskite has been broadly recognized as an effective strategy to enhance the performance of perovskite solar cells (PSCs). However, the mechanism governing the 2D phase formation remains uncertain. In this work, the phase t...
