Highly sensitive MoS2 photodetectors with graphene contacts.
Peize Han,Luke St. Marie,Qing X. Wang,Nicholas Quirk,Abdel El Fatimy,Masahiro Ishigami,Paola Barbara +6 more
TL;DR: In this paper, a large-area MoS2 grown by chemical vapor deposition and patterned by photolithography yields highly sensitive photodetectors, with record shot-noise-limited detectivities of 8.7 × 1014 Jones in ambient condition and even higher when sealed with a protective layer.

Evaluation of the effectiveness and compatibility of nanolime for the consolidation of earthen-based murals at Mogao Grottoes
TL;DR: Wang et al. as discussed by the authors used nanolime for the conservation of Chinese earthen-based murals with multilayer structure, and the effectiveness and compatibility of using it for conservation of Dunhuang murals were evaluated.

Creating Optoelectronic Devices from Atomically Thin Materials Grown by Chemical Vapor Deposition
TL;DR: In this paper, the authors used as-grown materials such as graphene and transition metal dichalcogenides (TMDs) to create ultra-thin optoelectronics that can be flexible and semitransparent.
