The Effect of Alloying Elements and Impurities on the Composition and Formation of Intermetallic Particles in Titanium and Titanium Alloys

open access: yesSurface and Interface Analysis, EarlyView.
ABSTRACT The corrosion resistance of alpha and near‐alpha titanium alloys has resulted in their widespread application in extreme environments. Their corrosion behavior is often influenced by their microstructure, particularly intermetallic particles (IMPs), and even slight compositional variations can produce significant differences in microstructure ...

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction

open access: yesSmall, EarlyView.
Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...

Straintronics and Twistronics in 2D Materials: Structural Control and Predictive Design

open access: yesSmall, EarlyView.
Strain and twist engineering in 2D materials is established as a programmable design parameter responsible for reconstructing lattices, tuning interlayer coupling, and developing new quantum functionalities. Through the integration of advanced fabrication techniques, multiscale characterization, computational modeling, and machine learning, this review

Monodisperse Condensed Tannin and Derived Carbon Nanospheres Featuring Well‐Defined Surface‐Structured Metal Species

open access: yesSmall, EarlyView.
Uniform, size‐tunable polyphenol nanospheres are assembled from condensed tannins in water at ambient conditions via controlled supramolecular interactions between tannin and diamines. Their phenolic–amine surfaces template highly dispersed metal species that resist sintering during pyrolysis.

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Adsorption‐Programmed Transformation of a Two‐Dimensional Cu–Imidazolate Framework into Mn‐Integrated Catalytic Nanonetwork

open access: yesSmall, EarlyView.
A freeze‐dried copper‐based metal‐organic framework removes more than 95% of manganese from water. Capturing the metal reorganizes the framework, giving the used adsorbent a second life as a reusable catalyst that produces valuable ester products in yields up to 84%.
