Nature, 1871 HAVING read only yesterday the agonising account written by M. Marie-Davy and countersigned by M. Delaunay, descriptive of the Communists having made the Paris Observatory one of their chief strategical points, of the domes of the observatory having five hundred bullet-holes through them, and of the rabid attempts made by the citizens in arms, before ...

Ultra‐High Sensitivity, Wide‐Range Thermometry Based on High‐Quality Microscale Diamond Resonators
Advanced Materials, EarlyView.By combing high‐crystal quality single‐crystal diamond MEMS cantilevers with multi‐mode resonance, the groundbreaking microscale ultra‐high sensitivity ≈22 nK Hz−1/2 and resolution of 100 µK thermometry is achieved. The diamond MEMS thermometry can operate over a wide temperature range from 6.5 to 380 K. This work underscores diamond MEMS resonators as

Bimodal Spin Switch Emerging from Hybridized 2D MoS2/Ferromagnet Interfaces
Advanced Materials, EarlyView.This study demonstrates a novel integration of 2D semiconductors with ferromagnets using pulsed laser deposition, revealing hybridization‐driven spin manipulation. Vertical spin valves with MoS2 and Ni(111) show exotic bimodal spin signals and strong deviations from Jullière's model. These results highlight the « 2D spinterfaces » key role in unlocking

Khartoum for an Observatory [PDF]
Nature, 1911 AT a time when search is being prosecuted in northern Africa (NATURE, September 21, p. 393) for an observatory site, it may not be out of place to direct attention to the merits of the Khartoum vicinity, so far as this can be done by one who is not an astronomer. Its features may be enumerated as follows:—

Advanced Optical Materials, EarlyView.Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...
