Small, EarlyView.This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...

Small, EarlyView.Electrically reconfigurable diffraction gratings based on electrophoretic carbon black (CB) nanoparticles are demonstrated. Voltage‐driven particle redistribution forms periodic absorbing patterns with switchable wide‐ and narrow‐slit diffraction modes. The proposed diffractor exhibits negligible polarization dependence, wide‐temperature operation from

Molecular Friction Trumps Viscosity in Angstrofluidic Transport
Small, EarlyView.Single‐file transport through sub‐1 nm graphene nanopore and carbon nanotube is investigated using molecular dynamics and ergodic trajectory sampling. The study shows that confinement geometry and wall‐fluid interaction strength govern molecular mobility, allowing atomistic motion to be translated into a continuum‐based resistance coefficient for ...

Environmental Toxicology, EarlyView.ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Strategies for enhancing sensitivity in lateral flow assays
VIEW, EarlyView.Lateral flow assays (LFAs) are essential for cost‐effective, rapid point‐of‐care diagnostics. However, conventional colourimetric LFAs often lack the sensitivity required for low‐abundance biomarkers. This review evaluates six enhancement strategies: flow modulation, sample preconcentration, advanced reporters, chemical signal amplification, structural

Improving ARTs: Microfluidics as a Tool for Sperm Selection
Andrology, EarlyView.ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.
