Next-Generation Self-Powered Photodetectors using 2D Bismuth Oxide Selenide Crystals.

The concept of self-powered photodetectors has attracted significant attention due to their versatile applications in areas such as intelligent systems and hazardous substance detection. Among these, junction and Schottky junction photodetectors are the most widely studied types; however, their fabrication processes are often complex and costly. To overcome these challenges, we focused on the emerging self-powered, ultrasensitive photodetector platform based on photoelectrochemical (PEC) principles.

Measurement of energy and directional distribution of neutron ambient dose equivalent for the Li(p,n)Be reaction.

Double differential neutron fluence distributions were measured in the Li(p,n)Be reaction for proton beam energies 7, 9 and 12 MeV. Seven liquid scintillator based detectors were employed to measure neutron fluence distributions using the Time of Flight technique. Neutron ambient dose equivalents were determined from the measured fluence distribution using ICRP (International Commission on Radiological Protection) recommended fluence to dose equivalent conversion coefficients.

N-methyl-pseudouridine is incorporated with higher fidelity than pseudouridine in synthetic RNAs.

In vitro transcribed synthetic messenger RNAs (mRNAs) represent a novel therapeutic modality. To overcome the inherent immunogenicity, as well as to increase the therapeutic efficacy of the molecules, uridine analogs-such as pseudouridine (Ψ) and N-methyl-pseudouridine (m1Ψ), are incorporated in the synthetic mRNA. To decipher the fidelity with which these modifications are incorporated during the in vitro transcription (IVT) process, we compared the incorporation fidelity of uridine analogs with different RNA polymerases.
