This work examines the application of a geometric-optical canopy reflectance model to provide measures of woody shrub abundance in desert grasslands at the landscape scale. The approach is through inversion of the non-linear simple geometric model (SGM) against 631 nm multi-angle reflectance data from the Compact High Resolution Imaging Spectrometer (CHRIS)(More)
This paper reports a new technique that combines the features of Accumulative Roll Bonding (ARB) and Asymmetric Rolling (AR). This technique has been developed to enable production of ultra-thin bimetallic foils. Initially, 1.5 mm thick AA1050 and AA6061 foils were roll-bonded using ARB at 200°C, with 50% reduction. The resulting 1.5 mm bimetallic foil was(More)
Red (672 nm) band reflectance estimates from the NASA Multi-angle Imaging Spectro-Radiometer (MISR) on the Earth Observing System Terra satellite were used to obtain maps of woody plant fractional crown cover, mean canopy height, and biomass for large parts of south-eastern Arizona and southern New Mexico (>200,000 km). MISR red band bidirectional(More)
A novel luminescent "double recognition" method for the detection of enrofloxacin (ENR) is developed to overcome some of the challenges faced by conventional molecularly imprinting. Biotinylated ENR aptamers immobilised on upconversion nanoparticles (UCNPs) surface are implemented to capture and concentrate ENR as the first imprinting recognition safeguard.(More)
Shoreline information is fundamental for understanding coastal dynamics and for implementing environmental policy. The analysis of shoreline variability usually uses a group of shoreline indicators visibly discernible in coastal imagery, such as the seaward vegetation line, wet beach/dry beach line, and instantaneous water line. These indicators partition a(More)

The paper studied the characteristics of arid and semi-arid lands carefully and an inversion method of a non-linear simple geometric model (SGM) with multi-angle CHRIS data was investigated and the results were reasonable. Some questions are listed below in detail. (1) Is the resolution between (a) and (b) the same? Response: We assume the reviewer is(More)
We report the synthesis and self-assembly of a new pi-conjugated dichalcone substituted carbazole-based low molecular mass organogelator. It could form stable gels in most halogen-aromatic solvents. The transmission electron microscopy (TEM) images revealed that the gel formed fibrous structures with diameter of 50-100 nm, which consisted of several thinner(More)
A thorough review on the patents in the applications of nano-powder technology shows that research work in this technical field is growing stronger, as indicated by a rapid increase in the number of independent patents in relevant topics. This also indicates ever increasing and continuous interests on the nano-powder technology even after 15 years of(More)
