They fabricate hydrogen sulfide (H2S) gas sensors using the film, which can detect the target gas under humid conditions, and exhibit the highest sensing performance to date.

氣體傳感器

在文章編號(hào)2107696中，Il Doo Kim、Steve Park及其同事介紹了一種基于微流體的溶液剪切與合成后快速結(jié)晶（MASS-PRC）工藝相結(jié)合的方法，該方法能夠以快速大面積可擴(kuò)展的方式形成高質(zhì)量的導(dǎo)電、柔性和透明Ni3（HITP）2膜，其厚度可控性低至10nm。他們使用該薄膜制造了硫化氫（H2S）氣體傳感器，該傳感器可以在潮濕條件下檢測(cè)目標(biāo)氣體，并表現(xiàn)出迄今為止最高的傳感性能。

Patterned Surfaces

Patterned surfaces can enhance the sensitivity of laser desorption ionization mass spectrometry by segregating and concentrating analytes, but their fabrication is challenging. In article number 2108194, Adam R. Abate and co-workers introduce a simple method to pattern substrates with micrometer-scale wells yielding more-sensitive mass spectrometry measurements compared to flat-surface or cylindrical wells. The wells also concentrate and localize cells and beads for cell-based assays.
