Crystal Engineering of Reticular Materials for Gas‐ and Liquid‐Phase Hydrocarbon Separation
Crystal engineering enables systematic study of structure/function relationships as exemplified by pore engineering of reticular sorbents, including porous coordination networks and covalent organic frameworks. This review assesses such studies applied across the full scope of industrially relevant hydrocarbon separations to provide insight into how ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

Angular correlation of the stellar scintillation on large telescopes
The stellar scintillation is one of the fundamental limitation to the precision of ground-based photometry. The paper examines the problem of correlation of the scintillation of two close stars at the focus of a large telescope.

We report molecularly engineered 2D COF films for high‐performance humidity sensors. The developed COFTPT‐THTA ultrathin film features triazine‐functionalized π‐conjugated backbones and high‐density surface hydroxyl groups. This unique architecture facilitates an electron‐proton coupled transport mechanism.

Galaxies at z=4 and the Formation of Population II
We report the discovery of four high-redshift objects (3.3 < z < 4) observed behind the rich cluster CL0939+4713 (Abell 851). One object (DG 433) has a redshift of z=3.3453; the other three objects have redshifts of z\approx 4: A0 at z=3.9819, DG 353 and

Spin‐Dependent Photoluminescence in Carbon‐Based Quantum Dots
Here we report, for the first time, room‐temperature magneto‐photoluminescence and optically detected electron spin‐resonance in carbon quantum dots (CQD). We perform measurements on a series of amino acid derived CQD at room temperature and demonstrate their sensing potential by detecting paramagnetic molecules in solution.

Deployable 3D‐Printed Vascular Stent with Surface‐Catalysed Endogenous Nitric Oxide Generation
A deployable 3D‐printed vascular stent was fabricated with surface‐catalyzed endogenous nitric oxide generation, representing a promising new direction for stent development. The stent can be remotely controlled by magnetic force in its compressed state and fully deployed at the target site using an untethered heat source, potentially eliminating the ...
