Single‐Crystalline Lateral p‐SnS/n‐SnSe van der Waals Heterostructures by Vapor Transport Growth with In Situ Bi Doping

Advanced Functional Materials, EarlyView.
In‐situ doping during growth of SnSe and subsequent attachment of SnS produces high‐quality lateral pn‐heterojunctions between van der Waals semiconductors. Electron beam induced current measurements demonstrate electrically active pn‐junctions, paving the way for devices that harness charge separation at lateral interfaces in layered heterostructures.

Tuning the Selectivity of the CO2 Reduction Reaction by Means of Synergistic Interactions in the Cu, Ag, Ce System

Advanced Functional Materials, EarlyView.
Multi‐metal Cu─Ce─Ag nanoparticles harness synergistic interactions to drive efficient electrochemical CO2 reduction reaction toward C2+ products at high current densities. Ag enhances CO production, Ce modulates Cu oxidation states, and together they boost *CO coverage and local pH to enhance C─C coupling, enabling record C2+ yields with suppressed ...

Mechanical alloying of Mg2Si

Scripta Metallurgica et Materialia, 1995
Mg{sub 2}Si is an intermetallic compound with low density (1.95 gcm{sup {minus}3}) and a rather high melting point (1,087 C). Due to its lightweight and thermophysical properties it is suitable for structural applications. It is also promising as a basic material for the thermoelectric energy conversion. A problem is its synthesis because magnesium and

ALLOY PHASE FORMATION BY MECHANICAL ALLOYING: CONSTRAINTS AND MECHANISMS

Modern Physics Letters B, 1992
Alloy phase formation in binary metallic systems by mechanical alloying (MA) of elemental powders is briefly reviewed. Our recent results indicate the inadequacy of the current understanding of the MA process, which has been depicted as an isothermal solid-state interdiffusion reaction under interfacial, metastable, equilibrium in layered composites ...

Mechanical behavior and properties of mechanically alloyed aluminum alloys

Metallurgical and Materials Transactions A, 1996
The fracture and deformation behaviors of several product forms produced from mechanically alloyed (MA) aluminum alloys 9052 and 905XL were studied. The main operative strengthening mechanism is strengthening due to the submicron grain size. Ductility and toughness were found to be controlled by the morphology of the prior particle boundaries.

The mechanism of mechanical alloying

Metallurgical transactions, 1974
The mechanical alloying process is a new method for producing composite metal powders with controlled microstructures. It is unique in that it is an entirely solid state process, permitting dispersion of insoluble phases such as refractory oxides and addition of reactive alloying elements such as aluminum and titanium.

Mechanisms of Mechanical Alloying

1998
Unlike conventional processes in which materials are produced either by melting or sintering at high temperature, synthesis of different types of materials using the mechanical alloying or milling process is generally carried our at room temperature although temperature may rise during milling.
