Two geographers specializing in China analyze that country's health care inequality from 1990 to 2008, for the purpose of: (1) examining spatial-temporal variations of health care inequality at multiple scales (the regional, provincial, and county levels); (2) exploring whether economic growth and transition to a market economy have exacerbated the… (More)
This paper advances the multi-scale and multi-mechanism framework of regional inequality in China by using the most recent statistical data. We analyze the multi-scalar patterns of China's regional inequality with GIS and statistical techniques, and demonstrate the significance of the municipality effect. The authors also apply multilevel modeling to… (More)
Graphene has a unique atom-thick two-dimensional structure and excellent properties, making it attractive for a variety of electrochemical applications, including electrosynthesis, electrochemical sensors or electrocatalysis, and energy conversion and storage. However, the electrochemistry of single-layer graphene has not yet been well understood, possibly… (More)
Aberrant expression of musashi2 (MSI-2) has been detected in several malignancies. However, its role in the progression of colorectal cancer (CRC) remains unknown. Our study was designed to investigate the expression and prognostic significance of MSI-2 protein in patients with colorectal cancer. The expression of MSI-2 was detected in 164 patients'… (More)
A fibre-shaped solid electrochemical capacitor based on electrochemically reduced graphene oxide has been fabricated, exhibiting high specific capacitance and rate capability, long cycling life and attractive flexibility.
Glutamate dehydrogenase (GDH) is a key enzyme that catalyzes the final reaction of the glutamine metabolic pathway, and has been reported implicated in tumor growth and metastasis. However, it’s clinical significance and role in colorectal cancer (CRC) pathogenesis is largely unknown. The expression of GDH was determined by qPCR, western blot and… (More)
An improved hydrothermal process is developed to fabricate macroporous graphene monoliths (MGMs) using a soft template of organic droplets. The MGMs are constructed from closed-cell distorted spherical pores. This unique microstructure makes MGMs that have low weight densities, good electrical conductivities, and excellent elasticity with rapid recovery… (More)
This paper implements a cyber-platform which visualizes and analyzes spatial patterns of flooding with a user-oriented spatial intelligence. The paper is organized from three perspectives: first, why representation and modeling of flooding data set is vital; second, how the design of flooding analysis involves spatial intelligence ; third, why flooding… (More)
Graphene oxide membranes (GOMs) are mechanically stable in various organic solvents, and their nanochannels can be narrowed by thermal annealing or widened by solvation. Therefore, the semipermeability of GOMs can be easily modulated, and they can be used as "multipurpose membranes" for molecular sieving in organic media.
Graphene oxide (GO) fractionation is achieved by size-exclusive passing of GO sheets through size-defined pores of track-etched membranes, which separate the GO sample into three portions with narrow size distributions. The method reported can be used for the performance improvement of graphene-based materials.
