Investigation on the hot ductility of Q235 low-carbon steel with boron addition
Results in Physics, 2019 We tested the mechanical properties of B-containing steel at 600–1300 °C using Gleeble 1500, and the hot ductility was investigated according to the reduction in area (RA). The fractured specimens were examined using scanning electron microscopy.

Boron determination in steels by Inductively-Coupled Plasma spectometry (ICP) [PDF]
, 1985 The sample is treated with 5N H2SO4 followed by concentrated HNO3 and the diluted mixture is filtered. Soluble B is determined in the filtrate by Inductively-Coupled Plasma (ICP) spectrometry after addition HCl and extraction of Fe with ethyl-ether.

Advanced Functional Materials, EarlyView.A dual‐functional Li2B4O7 coating on carbon fibers is designed to resolve the critical interfacial degradation in sulfide all‐solid‐state batteries. The conformal layer acts as a physical barrier to suppress parasitic reactions while its unique dielectric properties simultaneously facilitate Li+ transport.

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications
Advanced Functional Materials, EarlyView.Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified
