High-performance triboelectric nanogenerators based on TPU/mica nanofiber with enhanced tribo-positivity

open access: yesNano Energy, 2023
Kelvin probe force microscopy (KPFM) measurements of single pure TPU and TPU/mica nanofibers showed mica apparently enhanced the positive electrostatic surface potential (ESP) of TPU. The mean peak ESP of pure TPU nanofiber was about 194 mV, while it was

The MHC class I MICA gene is a histocompatibility antigen in kidney transplantation

open access: yesNature Medicine, 2022
The identity of histocompatibility loci, besides human leukocyte antigen (HLA), remains elusive. The major histocompatibility complex (MHC) class I MICA gene is a candidate histocompatibility locus.

Estimation of the net influx rate Ki and the cerebral metabolic rate of glucose MRglc using a single static [18F]FDG PET scan in rats

open access: yesNeuroImage, 2021
Since accurate quantification of 2-deoxy-2–18F-fluoro-D-glucose ([18F]FDG) positron emission tomography (PET) requires dynamic acquisition with arterial input function, more practical semi-quantitative (static) approaches are often preferred.

The percutaneous learning curve of 3rd generation minimally-invasive Chevron and Akin osteotomy (MICA).

open access: yesFoot and Ankle Surgery, 2022
BACKGROUND Minimally-invasive Chevron and Akin osteotomy (MICA) represents the third-generation percutaneous hallux valgus surgery which is characterized by an extra-articular osteotomy, stable internal fixation and a high potential for correction ...

Pairwise-Covariance Multi-view Discriminant Analysis for Robust Cross-View Human Action Recognition

open access: yesIEEE Access, 2021
Human action recognition (HAR) under different camera viewpoints is the most critical requirement for practical deployment. In this paper, we propose a novel method that leverages successful deep learning-based features for action representation and ...

Graphene adhesion on mica: Role of surface morphology [PDF]

open access: yes, 2011
We investigate theoretically the adhesion and electronic properties of graphene on a muscovite mica surface using the density functional theory (DFT) with van der Waals (vdW) interactions taken into account (the vdW-DF approach).
