Liquid‐Phase Fabrication of Janus 2D Materials: Defect‐Rich MoS2 Ultrathin Layers Asymmetrically Decorated with Au Nanoparticles

Small, Volume 22, Issue 25, 4 May 2026.
This work presents a versatile strategy for asymmetrically decorating MoS2 flakes using SiO2 microspheres as masking templates. The Janus MoS2 exhibits a 1.9‐fold enhancement in photoluminescence (PL) due to the incorporation of Au nanoparticles (NPs), primarily dominated by B exciton emission, which is attributed to defect‐rich structures.

An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These

Whipped and Mixed Warm Clouds in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework

Advanced Materials, Volume 37, Issue 52, December 29, 2025.
The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐

Bi–Sb Co‐Alloying Tunes Photoexcited State Dynamics in (4FPEA)4AgBi1−xSbxI8 Layered Double Perovskites through Structural Confinement

Advanced Optical Materials, Volume 13, Issue 36, December 19, 2025.
Lead‐free double perovskites are emerging alternatives to lead‐halide analogues, leveraging low toxicity and highly tunable chemical compositions. These materials possess unique carrier dynamics, often governed by self‐trapped exciton (STE)‐mediated recombination.

Atomic Scale Visualization of Vibrational Modes in Armchair Graphene Nanoribbon

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
To visualize the vibrational modes of armchair graphene nanoribbons and verify theories, a functionalized scanning tunneling tip is used to enhance the inelastic tunneling channel over the elastic one. Results show that edge phonons are localized than bulk phonons with little influence from substrate interactions.

Room Temperature Spin‐Dependent Transport in 2D Hofmann‐Type Single‐Layer Network

Small, Volume 21, Issue 50, December 17, 2025.
Room‐temperature magnetoresistance effect in a 2D magnetic Hofmann‐type network has been found using break junction scanning tunneling microscopy technique. A [Pt(CN)4Co]x system is grown on a gold substrate using 4‐mercaptopyridine ligands as anchoring ligands with a magnetic nickel tip. The reversal of the tip magnetization results in the shutdown of
