Mechanical properties of freely suspended atomically thin dielectric layers of mica
Nano Research, 2012 We have studied the elastic deformation of freely suspended atomically thin sheets of muscovite mica, a widely used electrical insulator in its bulk form.

Water-Gated Charge Doping of Graphene Induced by Mica Substrates
Nano Letters, 2012 We report on the existence of water-gated charge doping of graphene deposited on atomically flat mica substrates. Molecular films of water in units of ~0.4 nm-thick bilayers were found to be present in regions of the interface of graphene/mica hetero ...

NeuroImage, 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.

Pairwise-Covariance Multi-view Discriminant Analysis for Robust Cross-View Human Action Recognition
IEEE 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]
, 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).

Encoding Capacity Enhancement for Chipless RFID Tag Using Resonant Frequency Placement
IEEE Access, 2023 In this study, a novel encoding approach for chipless radio frequency identification (RFID) tags is proposed. This tag is designed with $N$ resonant elements, each of which can be parameterized to resonate at $M$ individual desired frequencies ...
