The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

A Comparative Study of the Influence of Water and Temperature on the Racemization of Five‐ and Six‐Membered l‐Alanine‐Derived Imides

Chirality, Volume 38, Issue 8, August 2026.
Racemization of chiral imides in dimethylformamide is shown to increase with increasing water content and temperature. The six‐membered imide ring system is more stable than the five‐membered analogue, with slower racemization under identical conditions and an absence of competing side reactions.

Full Vectorial Field Sensing Using Liquid Crystal Droplet Arrays

Advanced Materials, Volume 38, Issue 39, 13 July 2026.
An inkjet‐printed liquid crystal droplet array enables compact, low‐cost, single‐shot sensing of the full vectorial light field. Within a single platform, it simultaneously retrieves intensity, polarization, and phase, while dual‐wavelength operation highlights its capability for multi‐wavelength optical field characterization. ABSTRACT Determining the

2D Magnetic and Topological Quantum Materials and Devices for Ultralow Power Spintronics

Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.
2D magnets and topological quantum materials enable ultralow‐power spintronics by combining robust magnetic order with symmetry‐protected, Berry‐curvature‐driven transport. Fundamentals of 2D anisotropy and spin‐orbit‐coupling induced band inversion are linked to scalable growth and vdW stacking.

General Calibration Algorithm for Single-transmitting-dual-receiving Polarimetric SAR System

Leida xuebao, 2012
The single-transmitting-dual-receiving polarimetric SAR system has only two receving channels, which induces lack of prior information for calibration. Due to the polarization diversity of this kind of system (which operates on different dual and compact
