Physical Implementation of Optical Material‐Based Neural Networks Processing Enabled by Long‐Persistent Luminescence

open access: yesAdvanced Science, EarlyView.
This study reports on the physical implementation of optical material‐based neural processing using long‐persistent luminescence as memory‐retention and nonlinear optical material. The system performs optical‐domain preprocessing with opto‐electronic interfaces for stimulus delivery and readout, enabling real‐time demonstrations including Pong gameplay

Where have all the black holes gone? [PDF]

open access: yes, 2002
We have calculated stationary models for accretion disks around super-massive black holes in galactic nuclei. Our models show that below a critical mass flow rate of ~3 10**-3 M_Edd advection will dominate the energy budget while above that rate all the ...

Gate‐Dielectric Surface Engineering With Fluorinated Monolayers: Minimizing Contact Resistance and Nonidealities in OFETs

open access: yesAdvanced Electronic Materials, EarlyView.
Surface engineering of gate dielectrics with fluorinated self–assembled monolayers significantly improves the performance of organic field–effect transistors. In this study, Al2O3 functionalized with fluorinated phosphonic acids reduces contact resistance and hysteresis while achieving near‐zero threshold voltages, offering an alternative to ...

Radiation measurements from polar and geosynchronous satellites [PDF]

open access: yes
Towards understanding the role of radiation in the dynamics of climate, a climatology of radiation budget data has been compiled and several aspects of the problem are under study: (1) minimum albedoes; (2) diurnal variation in cloudiness and the ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

open access: yesAdvanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting
