Preparation of WC–xVC composite powders and the effect of high content VC on microstructure and mechanical properties of WC–Co based cemented carbides

Fenmo yejin jishu
The WC–xVC composite powders were synthesized by two-step carbothermal reduction process, and the WC–Co–VC cemented carbides with different mass fraction of Co (6% and 10%) were prepared by vacuum sintering method using the WC–xVC composite powders as ...

Layered Nanoporous Platforms for SERS Sensing

Advanced Materials Interfaces, EarlyView.
Here, we present a detailed investigation of the SERS performance of layered nanoporous metals. The controlled deposition of well‐defined, stacked porous layers enabled a systematic analysis of the effects of multimetallic systems in SERS experiments. Numerical models are also used to support the experimental findings.
