Fully Passive Electrochemical Oxygen Sensor Enabled With Organic Electrochemical Transistor
Advanced Materials Technologies, EarlyView.A wireless oxygen sensor that operates with low power without batteries, using organic electrochemical transistors (OECTs) powered by near‐field communication (NFC) is presented. The sensor combines an oxygen‐permeable membrane and a gel electrolyte to detect oxygen in air and complex liquids, making way for sustainable sensor technologies.

Advanced Materials Technologies, EarlyView.In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

Yield estimation of summer maize based on multi‐source remote‐sensing data
Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022 Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution

What asteroseismology can do for exoplanets
EPJ Web of Conferences, 2015 We describe three useful applications of asteroseismology in the context of exoplanet science: (1) the detailed characterisation of exoplanet host stars; (2) the measurement of stellar inclinations; and (3) the determination of orbital eccentricity from ...

Has journal of astrophysics and astronomy a future?
Scientometrics, 1985 Using publication and citation counts, and data obtained from the editorial office ofJournal of Astrophysics and Astronomy, we conclude that this journal is truly international and stands a good chance of becoming one of the core journals of astronomy, provided it is marketed vigorously.

Advanced Materials Technologies, EarlyView.This study showcases the first‐ever demonstration of ovonic threshold switching (OTS) and resistive switching (RS) in ZnTe thin films fabricated via a fast, cost‐effective electrodeposition method. By controlling the deposition potential, ZnTe film is tuned to demonstrate OTS or RS behaviors, enabling the implementation of one‐selector‐one‐resistor ...
