Article Abstract
Two-dimensional (2D) layered materials have been studied in depth during the past two decades due to their unique structure and properties. Transition metal (TM) intercalation of layered materials have been proven as an effective way to introduce new physical properties, such as tunable 2D magnetism, but the direct growth of atomically thin heteroatoms-intercalated layered materials remains untapped. Herein, we directly synthesize various ultrathin heteroatoms-intercalated 2D layered materials (UHI-2DMs) through flux-assisted growth (FAG) approach. Eight UHI-2DMs (VNbS, CrNbS, MnNbS, FeNbS, CoNbS, CoNbSe, FeTaS, FeTaS) were successfully synthesized. Their thickness can be reduced to the thinnest limit (bilayer 2D material with monolayer intercalated TM), and magnetic ordering can be induced in the synthesized structures. Interestingly, due to the possible anisotropy-stabilized long-range ferromagnetism in FeTaS with weak interlayer coupling, the layer-independent magnetic ordering temperature of FeTaS was revealed by magneto-transport properties. This work establishes a general method for direct synthesis of heteroatom-intercalated ultrathin 2D materials with tunable chemical and physical properties.

Ultra-High Zinc Utilization Enabled by MXene Anode for Flexible Dual-Plating Zn-Br Microbatteries.
J Phys Chem Lett

College of Materials Science and Engineering, Sichuan University, No. 24 South Section 1, Yihuan Road, Chengdu 610065, P. R. China.
Aqueous zinc-ion microbatteries exhibit promising prospects for wearable devices due to their high safety and cost-effectiveness but face challenges such as low energy density and short cycle life. To address these challenges, a dual-plating flexible Zn-Br microbattery was developed using freestanding MXene films as a zinc metal free anode. The MXene anode retains no redundant Zn, as Zn from the electrolyte undergoes deposition/stripping reactions on its substrate, thereby eliminating the necessity for excess zinc.

Demonstration of a Novel Radiochemical Mix Diagnostic for Fusion Implosions at the National Ignition Facility.
Phys Rev Lett

General Atomics, La Jolla, California 92037, USA.
Mixing of the ablator material into the fuel of an inertial confinement fusion implosion reduces compression and enhances radiative losses, preventing ignition. We describe a novel use of charged-particle radiochemistry to measure the ablator mix in contact with the fusion hot spot. The capsule uses a graded Be-Cr layer to increase the confinement of the hot spot.

Background And Objective: Male fertility assessment through sperm morphology analysis remains a critical component of reproductive health evaluation, as abnormal sperm morphology is strongly correlated with reduced fertility rates and poor assisted reproductive technology outcomes. Traditional manual analysis performed by embryologists is time-intensive, subjective, and prone to significant inter-observer variability, with studies reporting up to 40% disagreement between expert evaluators. This research presents a novel deep learning framework combining Convolutional Block Attention Module (CBAM) with ResNet50 architecture and advanced deep feature engineering (DFE) techniques for automated, objective sperm morphology classification.
