Influence of the grain size of rolled sparingly alloyed steel on the quality of manufacture of gears

open access: yesЛитьë и металлургия
A rational set of mechanical properties and high hardenability of the diffusion layer ensure the use of sparingly alloyed steels for large‑module gears.

Fluorine‐Free Soft Nanocomposites for High‐Speed Liquid Impact Repellence

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐free soft nanocomposite coatings are developed using silicone oil‐mediated mechanical‐stiffness control, enabling ‘dry’ liquid‐repellent surfaces that resist high‐speed water jet impacts up to ∼60 m/s. By tuning nanoparticle loading and oil content, the coatings also achieve >90% optical transparency, amphiphobicity with impact resistance to ...

Bioinspired Stabilization of Fluorescent Au@SiO2 Tracers for Multimodal Biological Imaging

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates a bioinspired stabilization strategy for fluorescent gold‐silica nanoparticles. Inspired by natural biosilica maturation, high‐temperature calcination transforms the silica shells, preventing dissolution in cell culture media and intracellular environments.

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype

open access: yesAdvanced Functional Materials, EarlyView.
In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Hardenability, transformation and precipitation effects in vanadium steels. [PDF]

open access: yes
Recent work has highlighted unusual effects of vanadium when used in conjunction with other microalloying additions on the hardenability of steels. Positive and negative synergistic effects have been observed, but studies into the mechanisms have been ...

Anomalous Pressure‐Temperature Ultrahigh Sensitivities in Atomically Engineered Carbonitride MXenes for Multifunctional Wearable Human–Machine Interfaces: Joint Computational–Experimental Elucidations

open access: yesAdvanced Functional Materials, EarlyView.
Atomically engineered layered 2D Ti3CNTz carbonitride MXene exhibits ultrahigh heat and pressure sensitivity, enabling dual‐mode sensors with 300%–400% performance enhancement and durability for real‐time health‐monitoring interface devices. Precise nitrogen incorporation (e.g., Ti3C1.8N0.2Tz) boosts conductivity, enhancing temperature response, while ...

Effect of Manganese Content on Structure and Properties of Medium-Carbon Cold-Heading Steel

open access: yesTeshugang, 2017
The effect of 0. 75% ~ 1. 54% Mn on structure and properties of 4)16 mm hot-rolled coil of medium-carbon cold-heading steel (/% : 0.45C, 0. 22Si, 0. 75 ~ 1. 54Mn, 0. 007 ~ 0. 008P, 0. 003 ~ 0.004S) has been analyzed and studied.
