Advanced Science, Volume 13, Issue 38, 9 July 2026.A real‐time, non‐contact photoplethysmography (PPG) system based on InAs colloidal quantum dots (CQDs) synthesized via a seedless injection synthesis is demonstrated. The measured oxygen saturation shows considerable agreement with commercial PPG devices.

Astronomische Nachrichten, Volume 347, Issue 6, July 2026.ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Small, Volume 22, Issue 41, 22 July 2026.This study reports intrinsically stretchable neuromorphic devices that exhibit outstanding mechanical stability while fully preserving their electrical characteristics over 105 repeated deformation cycles under 50% tensile strain. Such robustness is achieved through a rational molecular design strategy that systematically modulates the chain packing of

Proton‐Radiation Hardening of High‐Speed Ge/Si Integrated Photodetectors for Space Applications
Nanophotonics, Volume 15, Issue 12, 25 June 2026.Hydrogen loading is demonstrated as a radiation‐hardening strategy for high‐speed Ge/Si integrated photodetectors under broadband proton irradiation. By suppressing irradiation‐induced leakage‐current growth and mitigating bandwidth degradation, hydrogen‐loaded devices maintain high‐speed operation and improved stability, providing a practical route ...

X-ray Spectroscopy of Galaxy Clusters
, 2009 Galaxy clusters, the largest clearly defined objects in our Universe, are ideal laboratories to study in detail the cosmic evolution of the intergalactic intracluster medium (ICM) and the cluster galaxy population. For the ICM, which is heated to X-ray radiating temperatures, X-ray spectroscopy is the most important tool to obtain insight into the ...

X-Rays from Clusters of Galaxies [PDF]
Highlights of Astronomy, 1977 The discovery of the extended sources of X-ray emission associated with clusters of galaxies was undoubtedly one of the most significant observations carried out by the Uhuru satellite (Gursky et al (1971), Giacconi et al (1974)). At the present time, there are more than 30 identifications and suggested associations of X-ray sources with clusters of ...

X-Ray Observations of Clusters of Galaxies [PDF]
Symposium - International Astronomical Union, 1978 X-ray astronomy has, in the past year, seen the publication of the second Ariel (2A) and fourth Uhuru (4U) catalogues of X-ray sources. A number of new X-ray cluster identifications and the confirmation of several others has resulted. in this review I will briefly summarise the situation regarding identifications and, for the 2A clusters, discuss the ...
