Graphene is considered as a promising candidate material to replace silicon for the next generation nanoelectronics due to its superb carrier mobility. To evaluate its thermal dissipation capability as electronic materials, the thermal transport in monolayer graphene was extensively explored over the past decade. However, the supported chemical vapor deposition (CVD) grown monolayer graphene with submicron structures were seldom studied, which is important for practical nanoelectronics. Here we investigate the thermal transport properties in a series of CVD graphene nanomeshes patterned by a hard-template-assisted etching method. The experimental and numerical results uncovered the phonon backscattering at hole boundary (< 100 nm neck width) and its substantial contribution to the thermal conductivity reduction.

Hybrid 3D nanoarchitectures by covalent connection of 1D and 2D nanomaterials are currently in high demands to overcome the intrinsic anisotropy of the parent materials. This letter reports the juncti...
Graphene nanomesh (GNM) is formed by patterning graphene with nanometer-scale pores separated by narrow necks. GNMs are of interest due to their potential semiconducting characteristics when quantum c...
Contact Resistance (R<sub>C</sub>) is a major limiting factor in the performance of graphene devices. RC is sensitive to the quality of the interface and the composition of the contact, wh...
Grain boundaries in graphene are inherent in wafer-scale samples prepared by chemical vapor deposition. They can strongly influence the mechanical properties and electronic and heat transport in graph...
We investigate thermally driven water droplet transport on graphene and hexagonal boron nitride (h-BN) surfaces using molecular dynamics simulations. The two surfaces considered here have di...
The purpose of this study is to evaluate the use of the VersaMed iVent ventilator in the acute care setting, hypothesizing that, in comparison to the standard approach, the use of the Vers...
The purpose of this study is to test the effectiveness of USES, a strengths-based enhancement to supported employment (SE), as compared to supported employment alone.
This is a study to evaluate thermal imaging as a technology to monitor the normal clearing of amniotic fluid from healthy newborns and newborns suspected of having a condition called trans...
Currently, there are no tools that can measure nasal airflow in an objective manner that is non-invasive to the patient. This clinical study aims to address this by evaluating the use of t...
The goal of this clinical research study is to evaluate whether thermal imaging (recording body temperature) can be used to check the body's response to cancer therapy. Primary Objective:...
Differential thermal analysis in which the sample compartment of the apparatus is a differential calorimeter, allowing an exact measure of the heat of transition independent of the specific heat, thermal conductivity, and other variables of the sample.
The process of moving proteins from one cellular compartment (including extracellular) to another by various sorting and transport mechanisms such as gated transport, protein translocation, and vesicular transport.
A broad category of proteins involved in the formation, transport and dissolution of TRANSPORT VESICLES. They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.
Membrane transport proteins found predominately in NEURONS and neuroendocrine cells that facilitate neurotransmitter transport. They include two distinct families of proteins that transport NEUROTRANSMITTERS across the PLASMA MEMBRANE and that transport NEUROTRANSMITTERS into SECRETORY VESICLES.
Disorders characterized by defective transport of amino acids across cell membranes. These include deficits in transport across brush-border epithelial cell membranes of the small intestine (MICROVILLI) and KIDNEY TUBULES; transport across the basolateral membrane; and transport across the membranes of intracellular organelles.
