Glaphene: A Hybridization of 2D Silica Glass and Graphene
Advanced Materials, EarlyView.‘Glaphene’, a novel hybrid material combining 2D silica glass and graphene, is synthesized via a scalable liquid precursor‐based vapor‐phase growth. This study reveals interlayer hybridization beyond van der Waals interactions, leading to emergent semiconducting behavior.

A test for the redshift dependence of $$\sigma _8$$ σ 8 using $$f\sigma _8$$ f σ 8 measurements
European Physical Journal C: Particles and FieldsWe search for a redshift dependence of $$\sigma _8^0$$ σ 8 0 using 23 growth rate measurements from redshift space distortions and peculiar velocity measurements as a consistency check of $$\Lambda $$ Λ CDM.

Electrostatic time dilation and redshift
Physics Letters B, 2020 We first present the salient features of the gravitational time dilation and redshift effects in two ways; by considering the oscillation frequencies/rates of clocks at different heights/potentials and by considering the photons emitted by these clocks ...

Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites
Advanced Materials, EarlyView.Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Cloud Inspired White and Grey Plasmonic Metasurfaces for Camouflaged Thermal Management
Advanced Materials, EarlyView.Inspired by clouds' role in Earth's thermal management, this work presents disordered plasmonic metasurfaces that mimic their radiative effects. The white metasurface enhances backscattering, acting as a cooling layer with camouflage properties.

Advanced Materials, EarlyView.A flame‐spray‐pyrolysis method is presented to synthesize ultra‐bright CTS nanosheets with tunable NIR‐II emission. Achieving quantum yields up to 34%, these materials support high‐speed imaging and enable super‐resolution in vivo applications such as transcranial microcirculation mapping and macrophage tracking.

The spatial distribution of GRBs
Acta PolytechnicaWe analysed the different aspects of the spatial distribution of 542 Gamma-Ray Bursts with precisely determined positions and spectroscopic redshifts. The data were divided according to the origin of the redshift (afterglow or host galaxy).
