Experimental study on patterns of fault interaction

Based on the data of strain field, fault slip and acoustic emission during the deformation of some fault models, the fault interaction patterns are studied. The experiments reveal four patterns of fault interaction, i.e. static promotion or delay of earthquake, creep triggering, dynamic triggering and dynamic loading-relaxation. Promotion and delay of earthquake caused by fault interaction and mechanical property of fault combinations are preliminarily analyzed from the perspective of series and parallel connection of faults, and the relationship between patterns of fault interaction and mechanical and material properties of fault is discussed.     

Decomposed characteristic of azo dyes by ozonization with ultrasonic enhancement

Azo dyes have been used in many industries (textile mill, printing and dyeing mill, paper and pulp mill) and have caused great environmental pollution due to complicated constitution and high chemical stability. The construction of azo dyes can be destroyed by ozonization, but not thoroughly when the ozone dosage is controlled to a certain extent and the operating cost is higher. Ozonization decomposed ability with ultrasonic enhancement on azo dyes has been demonstrated in the study. The conclusion derived from this investigation may be summarized as follows: (1) The decoloration rate of arsenazoⅠsolutions during sonozone treatment is more rapid than the rate obtained with ozone alone because the complicated constitution has been destroyed by the O free radical from ozone decomposition. (2) The destructing pathway of arsenazoⅠby ozone with ultrasound is identical with that of by ozone alone: the breakdown of —N== N— bonds, the conversion of benzene ring to carboxylic acid, and —HSO₃ bonds to H₂SO₄. So, pH value of the arsenazo Ⅰ solution continuously drops down to 3.2.     

Manipulation and cutting of carbon nanotubes

Nanomanipulation plays an important role in nanofabrication, it is also a technology necessary in exploring the secrets of nanoworld, and it thus beco mesa start point to research future nanomachine. In this study, manipulation and cutting of carbon nanotubes have been conducted in order to examine whether we can move a nanocomponent from one site to another by using the tip of atomic fo rce microscope (AFM). The technique may also be valuable for providing the const ructive materials of nanofabrication. While exploring the method for manipulatin g and cutting of nanotubes, some new phenomena have been observed during the process. Results show that carbon nanotubes present a feature of deformation combin ing bending and distortion when subjected to large mechanical forces exerted by the tip of AFM. In special cases, long carbon nanotubes can be cut into two part s, by which we can remove the part where crystal lattice is flawed, and therefor e a perfect nanocomponent can be obtained.     

Reductase activity of human thioredoxin-like protein and its effects on cell apoptosis

Thioredoxin is a ubiquitous dithiol oxidoreductase found in many organisms and involved in numerous biochemical processes. Human thioredoxin-like protein (hTRXL) is differentially expressed at different development stages of human fetal cerebrum and belongs to an expanding family of thioredoxins. Recombinant hTRXL and truncated hTRXLs corresponding to the N-terminal (hTRXL-N) and C-terminal (hTRXL-C) domains are expressed and purified. In insulin disulfide reduction assay, both full-length hTRXL and hTRXL-N show reducing activity for the insulin disulfide bonds. As expected, the hTRXL-C failed to reduce insulin. MCF-7 cell stably transfected with hTRXL cDNA exhibits increased sensitivity to apoptosis induced by phorbol myristic acetate (PMA) and ionomysin.
