Intravoxel water diffusion heterogeneity imaging of human high-grade gliomas
(John Wiley & Sons, Ltd., 2010-02)
This study aimed to determine the potential value of intravoxel water diffusion heterogeneity imaging for brain tumor characterization and evaluation of high-grade gliomas, by comparing an established heterogeneity index ...
Hot carrier cooling by acoustic phonons in epitaxial graphene by ultrafast pump-probe spectroscopy
(WILEY-VCH Verlag, 2011-04)
We report the application nondegenerate ultrafast mid-infrared spectroscopy to investigate the acoustic phonon cooling process in epitaxial graphene. We show that the power-dependent experimental results match theoretical ...
Engineering, Characterization and Directional Self-Assembly of Anisotropically Modified Nanocolloids
(WILEY-VCH Verlag, 2011-03-21)
Along with traditional attributes such as the size, shape, and chemical structure of polymeric micro-objects, control over material distribution, or selective compartmentalization, appears to be increasingly important for ...
Clot Retraction: A Miniaturized Hemoretractometer for Blood Clot Retraction Testing (Small 29/2016)
(Wiley Periodicals, Inc., 2016-08)
Discrete Ordinates Methods for Transport Problems with Curved Spatial Grids.
(2015)
The method of characteristics (MOC) has been favored for many recent whole core transport codes; some current research codes are: the nTRACER code from Seoul National University, the MPACT code from the University of ...
Structure-Property Relationships in Clay/Polymer Dispersions: Characterizing Bulk and Nanoscale Changes.
(2013)
Colloids and polymers are often used in industrial applications such as pharmaceuticals, food, paints, cosmetics and drilling fluids to achieve the desired properties. The work presented in this thesis focuses on the study ...
Microfluidic Automation Using Elastomeric Valves and Droplets: Reducing Reliance on External Controllers
(WILEY‐VCH Verlag, 2012-10-08)
This paper gives an overview of elastomeric valve‐ and droplet‐based microfluidic systems designed to minimize the need of external pressure to control fluid flow. This Concept article introduces the working principle of ...
Conducting-Polymer Nanotubes Improve Electrical Properties, Mechanical Adhesion, Neural Attachment, and Neurite Outgrowth of Neural Electrodes
(WILEY-VCH Verlag, 2010-02-05)
An in vitro comparison of conducting-polymer nanotubes of poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(pyrrole) (PPy) and to their film counterparts is reported. Impedance, charge-capacity density (CCD), tendency ...
High‐Motility Visible Light‐Driven Ag/AgCl Janus Micromotors
(Wiley Periodicals, Inc., 2018-11)
Visible light‐driven nano/micromotors are promising candidates for biomedical and environmental applications. This study demonstrates blue light‐driven Ag/AgCl‐based spherical Janus micromotors, which couple plasmonic light ...
