Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Topotactic Nitridation Enabled Core–Shell La4Ti3(O,N)12@LaTiO2N for Efficient Photoelectrochemical Water Splitting

Small, EarlyView.
Topotactic nitridation of (111)‐plane layered perovskite La4Ti3O12 proceeds through a persistent 2D layered oxynitride La4Ti3(O,N)12, enabling formation of a core–shell La4Ti3(O,N)12@LaTiO2N heterostructure before full conversion into 3D perovskite LaTiO2N.

Interlayer‐Catalyst Method for Metal‐Assisted Chemical Etching of Ultra‐High Aspect Ratio Silicon Nanostructures

Small Methods, EarlyView.
An advanced patterning method is presented for metal‐assisted chemical etching. The interlayer replaces the resist and enables catalyst deposition on a clean interface. The prepared samples show improved performance with a more reproducible etching profile, higher aspect ratio, and increased consistency over a larger area.

Integrated Delay Based Photonic Reservoir Computing

, 2018
We have analyzed the performance of a reservoir computing system based on a semiconductor laser with delayed optical output feedback on timeseries prediction and bit parity tests. Both laser and feedback section are fully integrated on an InP based photonic chip fabricated on the Jeppix platform.

Performance of commercial polyamide membranes in pervaporation for dye removal: Impact of dye classes, colors, and surfactants

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 9, Page 1742-1756, September 2026.
Abstract BACKGROUND Water reclamation in the textile industry is essential to reduce environmental impacts associated with high water consumption and pollutant discharge. Among emerging technologies, pervaporation (PV) has gained attention due to its high selectivity and efficiency in contaminant removal. However, there is still a lack of comprehensive

Spatiotemporal multiplexed photonic reservoir computing: parallel prediction for the high-dimensional dynamics of complex semiconductor laser network

Opto-Electronic Advances
Accurately forecasting the high-dimensional chaotic dynamics of semiconductor laser (SL) networks is essential in photonics research. In this study, we propose a spatiotemporal multiplexed photonic reservoir computing (STM-PRC) architecture, specifically

Alteration of X‐Ray Emission Band Spectrum Under Bragg Diffraction

X-Ray Spectrometry, Volume 55, Issue 5, Page 704-711, September/October 2026.
ABSTRACT We use a Zr/Si multilayer presenting a gradient of period to probe the shape of the Si L2,3 emission band (maximum around 92 eV) in and out of Bragg conditions. The sample was prepared by magnetron sputtering and its reflectance measured in the photon energy range of interest with synchrotron radiation.
