Strained 2D Semiconductor Lateral Heterojunctions via Grayscale Thermal‐Scanning Probe Lithography

open access: yesSmall Science, EarlyView.
A novel strain‐engineering approach using grayscale thermal‐Scanning Probe Lithography tailors the optoelectronic response of 2D Transition‐Metal Dichalcogenide (TMD) layers. Nanofaceted templates control local strain in MoS2, enabling engineered carrier extraction in asymmetric Au‐MoS2 lateral heterojunction nanoarrays, as detected by Kelvin Probe ...

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

open access: yessteel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Performance of two‐to‐one non‐contact post‐installed lap splices

open access: yesStructural Concrete, EarlyView.
Abstract Post‐installed lap splices ensure the continuity of steel reinforcement in concrete‐to‐concrete connections by overlapping cast‐in (CI) reinforcing bars (rebars) with post‐installed (PI) rebars. Typically, the design of such splices follows provisions originally intended for CI lap splices, despite the differences in execution and bond ...

Experimental investigation on post‐installed anchorages with cast‐in anchor reinforcement under tension loading

open access: yesStructural Concrete, EarlyView.
Abstract Anchors are used to connect different structural and non‐structural components to reinforced concrete structures. Anchorages when subjected to tension loading might fail in different failure modes, with concrete cone breakout (CCB) being one of the most common.

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The
