Microscale Contact Electrification with Unprecedented High Intrinsic Charge Density. [PDF]

Small
With the atomically flat contact interface by a microscale graphite slider and polytetrafluoroethylene, microscale contact electrification with high contact efficiency is achieved. The developed microscale triboelectric nanogenerator exhibits a record‐high intrinsic triboelectric charge density of 2.6 mC m−2, which is attributed to the greatly enhanced

Generation of Enucleated Erythrocytes From Lin^-CD45^-CD133⁺ Cells Isolated From Human Umbilical Cord Blood In Vitro. [PDF]

Stem Cells Int
Background At present, healthcare facilities often face blood shortages because of the low supply of donated blood relative to the high demand. Therefore, efforts to develop red blood cell (RBC) production methods have gained traction. In this work, Lin−CD45−CD133+ cells were isolated from human umbilical cord blood (UCB) and subsequently ...

Detection of Tibiofemoral Joint Injury in High-Impact Motion Based on Neural Network Reconstruction Algorithm.

J Healthc Eng, 2021
In order to reduce the damage degree of joint bones, ligaments, and soft tissues caused by the high impact on the tibiofemoral joint during landing, a method for detecting the damage of tibiofemoral joint under high‐impact action based on neural network reconstruction algorithm is proposed. Two dimensional X‐ray images of knee joints from straightening

Effect of micro- and nanomagnetite on printing toner properties. [PDF]

ScientificWorldJournal, 2014
Toner is a main component of electrophotographic printing and copying processes. One of the most important ingredients of toner is magnetite (Fe3O4) which provides the tribocharging property for toner particles. In this study, nano‐ and microparticles of Fe3O4 were synthesized using the coprecipitation method and different amounts of lauric acid as a ...

A neuromorphic system based on spiking‐timing‐dependent plasticity for evaluating wakefulness and anesthesia states using intracranial EEG signals

View
The primary method for assessing the depth of anesthesia during clinical surgeries currently relies on physiological and behavioral cues, such as heart rate, blood pressure, and reaction to external stimuli. These measures might not be dependable because
