Enzymatic hydrolysis of cellulose from biomass is potentially considered as a new approach for the next generation of biofuels for sustainable energy. However, because of the rigid and complex structure of cellulose, the low efficiency of the enzymatic hydrolysis has been deemed as the bottleneck in biorefining industry. The mechanism of enzymatic hydrolysis of cellulose is not well understood due...
Atomic Force Microscopy (AFM) is a powerful instrument for studying and exploring the nanoworld [1]. AFM can obtain ultrahigh-resolution images at the subnanoscale level. However, AFM has a very significant drawback of slow imaging speed, which is due to its working principle. A conventional AFM conducts a raster scan of an entire area to generate a topography image. Therefore, the frame rate is low,...
Infrared (IR) cameras have versatile applications, but their applications were limited by the performance of photodetectors. Carbon nanotube (CNT) has been used to develop high performance IR detectors with high switching speed, low noise, and non-cryogenic cooled operation. However, it is very difficult to fabricate large scale CNT photodetector array that can be integrated in traditional IR camera...
In this paper we discuss how to precisely reconstruct porous media 3D model and simulate the fluid flow in the porous media. Considering the characteristics of the porous media's fault slice images, we present a contour extraction algorithm and based on the extracted contour we acquire the sandwich fault images. We modify the original MC algorithm with bounding box technology to accelerate the running...
Atomic Force Microscopy (AFM) is a powerful tool for nano-size imaging. The advantage of AFM is that it can get extraordinary high resolution image at atom level. However, AFM obtains the sample topography image through scanning on the top of sample line by line, therefore it takes couples minutes to get an image and this negative point makes it difficult to continuously observe surface change during...
In this paper a method for precisely reconstructing porous media three-dimensional model based on slice images is proposed. It first processes the original slice images, then uses 3D seed filling algorithm to find all pores based on the constructed spatial data, finally uses the modified marching cubes algorithm based on bounding box technology to render material skeletons and pores. Associating with...
