Multifunctional Chiral Halide Perovskites: Advancing Chiro‐Optics, Chiro‐Optoelectronics, and Spintronics

open access: yesAdvanced Science, EarlyView.
This review spotlights key advances in chiral halide perovskite materials and devices, covering device architectures, fabrication methods, and emerging applications like circularly polarized light functions, neuromorphic computing, and spintronics. It explores structure‐property relationships and chirality transfer mechanisms, discusses challenges in ...

Gas stripping in galaxy groups - the case of the starburst spiral NGC 2276 [PDF]

open access: yes, 2006
Ram pressure stripping of galactic gas is generally assumed to be inefficient in galaxy groups due to the relatively low density of the intragroup medium and the small velocity dispersions of groups.

Isolated Galaxies, Pairs and Groups of Galaxies [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
We searched for isolated galaxies, pairs and groups of galaxies in the CfA survey (Huchra et al. 1983). It was assumed that the distances to galaxies are given by R = V/H0, where H0 = 100 km s−1 Mpc−1 and R> 6 Mpc.

α‐Helix‐Driven Regulation of Aqueous Circularly Polarized Luminescence in Homopolypeptide Self‐Assembly

open access: yesAggregate, EarlyView.
We explore the hierarchical chirality transfer in self‐assembled fluorescent homopolypeptide systems for achieving aqueous circularly polarized luminescence (CPL), and reveal the α‐helix‐dominated CPL regulation mechanism during the self‐assembly process .

The Orientation of Galaxies in Nearby Galaxy Groups [PDF]

open access: yesSymposium - International Astronomical Union, 2004
The statistical analysis of six nearby groups of galaxies, connected with the Milky Way, M31, M81, M101, NGC5128 and NGC5236 shows an isotropic distribution of galaxy planes, similarly to galaxies within the Local Group. Also planes of galaxies in the nearby (Vr < 500 km s−1) region of the Local Supercluster exhibit random distribution, disregarding

AIEgen‐Based and Smartphone‐Assisted On‐Site Quantitation of Cystatin C for Monitoring of Chronic Kidney Disease

open access: yesAggregate, EarlyView.
By employing new protein‐templated AIEgen Ir@BSA as the phosphorescence signal indicator and papain as the biomolecular recognition element, a straightforward protocol for Cys C quantitation has been developed. On‐site quantitation of Cys C in clinical serum samples has been successfully demonstrated using a smartphone‐based portable phosphorescence ...

The origin of redshift asymmetries: How LambdaCDM explains anomalous redshift

open access: yes, 2008
Several authors have found a statistically significant excess of galaxies with higher redshifts relative to the group centre, so-called discordant redshifts, in particular in groups where the brightest galaxy, identified in apparent magnitudes, is a ...

Tau Amyloid Corona‐Shelled Nanoparticle‐Based Drug Screening Platform for Discovering Tau Oligomer‐Degrading Drugs

open access: yesAggregate, EarlyView.
Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.
