Multiband Optical Physical Unclonable Functions Based on Mixed‐Phase Multilevel Emissive Perovskites

open access: yesAdvanced Science, EarlyView.
In this paper, sustainable multiband optical PUFs were developed by constructing heterostructures between lead‐free phase‐mixed perovskites and cellulose fibers via a water‐assisted drop‐casting process. Cesium manganese bromide perovskites provide an environmentally benign composition while exhibiting excitation‐dependent multilevel photophysical ...

Energy Matching in NV Spin‐Phonon Interaction Enabling High‐Temperature Quantum Sensing via Lifetime Readout

open access: yesAdvanced Science, EarlyView.
Quantum sensing at high temperatures is challenging for the NV center. We overcome this by revealing an energy matching within NV spin‐phonon interactions. This match preserves high sensitivity upon heating. By reading out the NV excited state lifetime, we demonstrate a shot‐noise‐limited sensitivity of 8.3 µK Hz−1/2 at 490 K, paving the way for robust

СамоубиÑтвата во Скопје и околината во текот на 1979 година

open access: yes, 2017
The aim of our examination was to establish the number of suicides, oldness, sex, professions, calendar and meteorological time, place, manner and means of execution. Our basic duty was to analyse this phenomenon, which number rise slowly, from the year (

SensEnhance: A Genetic Circuit for Converting Endogenous Mammalian Gene Signals Into High‐Dynamic‐Range Genetic Readouts

open access: yesAdvanced Science, EarlyView.
Here, we present SensEnhance, a modular genetic circuit that converts leaky, low‐dynamic‐range promoter signals into tightly controlled, high‐dynamic‐range outputs. Applied to mechanosensing and IL‐6‐responsive promoters, SensEnhance increases fold changes from 2.6‐ and 2.5‐fold in promoter‐only configurations to over 20‐ and 14‐fold, respectively ...

Strain‐Enhanced Ultrastretchable Semiconducting Polymer Fibers for Organic Electrochemical Transistors

open access: yesAdvanced Science, EarlyView.
The continuous fabrication of stretchable polymer semiconductor p(g2T‐T) fibers is realized via wet‐spinning. The p(g2T‐T) semiconductor fibers possess an efficient strain energy dissipation mechanism and unique strain‐enhanced electrical performance. They can be stretched to over 250% strain and exhibit an ultrahigh normalized transconductance of 276 ...

Label‐Free Super‐Resolution Imaging Using Non‐Linear Exogenous Photon Avalanche Backlight

open access: yesAdvanced Science, EarlyView.
Transmission avalanche backlight (TAB) microscopy turns a photon‐avalanching Tm3+:LiYF4 crystal into a nonlinear luminescent backlight. Weak attenuation by a transparent sample is amplified into strong emission modulation: image contrast increases with sample attenuation and avalanche nonlinearity (N), while the effective point spread function narrows ...
