Tunneling in Persistent Luminescence

open access: yesAdvanced Optical Materials, EarlyView.
Key experimental criteria are provided for the occurrence of thermal/athermal tunneling and localized transitions. Many experimental studies of PersL have assigned tunneling on the basis of the linear relationship of PersL decay between intensity, I, and time, t−k, where k is a constant or I−1 versus t.

Three‐Component Synthesis of γ‐Amino Esters with α‐Quaternary Carbon Centers via NHC/Photoredox Dual Catalysis

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
γ‐Amino acid derivatives with an α‐quaternary center are prevalent in medicinally important compounds. A dual N‐heterocyclic carbene/photocatalytic pathway is developed for the three‐component synthesis of α, α ‐disubstituted γ‐amino esters. This methodology allows for the rapid synthesis of diverse libraries of γ‐amino esters in good yields.

Single‐Virus Stochastic Biosensing: Proof of Concept for SARS‐CoV‐2 Detection in Complex Medium Using CMOS‐Based Nanocapacitor Arrays

open access: yesAdvanced Sensor Research, EarlyView.
SARS‐CoV‐2 particles in complex cell culture medium are detected using high‐frequency electrical measurements. This is made possible through the use of large arrays of independently addressable nanoelectrodes implemented using complementary metal oxide semiconductor (CMOS), semiconductor technology.

Towards Neural‐Network‐Based Optical Temperature Sensing of Semiconductor Membrane External Cavity Laser

open access: yesAdvanced Sensor Research, EarlyView.
Neural‐network‐based (NN) temperature sensing: Machine‐learning non‐contact method for the determination of the temperature of a laser gain medium via its laser emission with few‐layer neural net (NN) regression model. Training the feed‐forward NN with data recorded by compact micro‐spectrometers for both a diode pump laser and optically‐pumped gain ...
