Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis

Small, EarlyView.
Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

Oxidation‐Induced Internal Chemical Patterning in Copper–Gold Nanoalloys

Small, EarlyView.
Surface oxidation suppresses Au surface segregation and redirects Au transport to twin boundaries, replacing conventional core–shell formation with internal chemical patterning. Driven by Cu–Au mixing thermodynamics, defect‐mediated uphill diffusion creates alternating Au‐rich and Cu‐rich lamellae, revealing oxidation as a chemical pump for bulk ...

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

Small, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Diverse DTPA‐chelated lanthanides with relevance for nuclear medicine bound to an engineered lipocalin reveal conserved ligand geometry

Acta Crystallographica Section F, EarlyView.
Structural and binding studies of the engineered lipocalin CL31d towards the chelate complexes of 11 different lanthanide and main‐group metal(III) ions, whose radioisotopes are useful for nuclear medicine, with a functionalized DTPA revealed a surprisingly broad tolerance towards varying ionic radii, thus enabling flexible radionuclide‐targeting ...

Comparison of different X‐ray‐based scanning electron microscopy methods to detect sub‐nanometre ultra‐thin InAs layers deposited on top of GaAs

Journal of Microscopy, EarlyView.
Abstract We compare three different methods of X‐ray analysis in a scanning electron microscope (SEM): energy‐dispersive X‐ray spectroscopy (EDX), wavelength‐dispersive X‐ray spectroscopy (WDX) and micro X‐ray fluorescence (μXRF). These methods are all applied to the same gallium arsenide (GaAs) wafer with a 0.8 nm layer of indium arsenide (InAs) on ...

Interfacial Engineering of Cu/ZnX2O4 (X = Ga, Cr, Al) Spinel‐Supported Catalysts for Enhanced CO2 Hydrogenation to Methanol

Carbon and Hydrogen, Volume 28, Issue 3, Page 349-359, September 2026.
Engineered Cu‐ZnGa interfaces on spinel supports enhance metal–support interaction and Cu dispersion, suppress reverse water‐gas shift, and achieve high CO2 conversion, methanol selectivity, and operational stability. ABSTRACT Catalytic hydrogenation of carbon dioxide to methanol is a key approach for carbon resource utilization and carbon neutrality ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Active Corrosion Protection of Sintered AA7075 Aluminum Alloy via Mn Powder Addition

Advanced Engineering Materials, Volume 28, Issue 16, 19 August 2026.
AA7075 containing Mn‐rich particles is fabricated via spark plasma sintering using AA7075 and Mn powders. Corrosion resistance is evaluated through dip‐and‐dry tests using 0.1 M NaCl (pH 6.0), and mass loss decreases with increasing Mn addition. Mn‐rich particles function as a source of Mn ions, and formation of Mn‐accumulation films on Cu‐containing ...
