Atomic-resolution image of a graphene sheet synthesized by remote plasma-enhanced atomic layer deposition at low temperatures.
An In₂O₃/ITO thin film thermocouple was prepared via screen printing. Glass additives were added to improve the sintering process and increase density of films. The surface cross-sectional images indicate that both grain size densification ITO In₂O₃ films increased with in annealing time. thermoelectric voltage 53.5 mV at 1270 °C hot junction. average Seebeck coefficient calculated as 44.5 μV/°C. drift rate 5.44 °C/h a measuring time 10 h °C.
The energy density and efficiency deteriorate slightly from room temperature to 150 °C.
Abstract Metal oxides have been extensively investigated in non-enzymatic biosensors for detecting diabetes owing to their electrochemical catalytic properties and excellent stability.

Derived from infrared pyroelectric detection, typical terahertz (THz) detectors have low sensitivity at low-frequency THz bands. Based on the high-efficiency absorption of metamaterial perfect absorber (MPA), a novel split ring hole metamaterial-enhanced detector is proposed to achieve efficient multi-narrowband detection. Using high frequency simulation software (HFSS), dimensional parameters including radius, width, connection beam array period, and thickness, are optimized enhance...

Inductive wear debris sensors are an indispensable tool for real-time monitoring. Traditionally, these contain only one type of magnetic field, time harmonic or static, and so cannot avoid the contradiction between magnetization eddy current, resulting in limited performance. In this article, a detection method based on biased fields is proposed first time, which can surpass limitation traditional sensors. By coupling high-gradient static high-frequency time-harmonic fields, sensor has...
