BMH is a new type of inorganic antibacterial agent. However, there is few study about BMH application in plastic film. So, in this study, BMH/PE films prepared by rolled was investigated in antimicrobial, mechanical and optical properties with different BMH contents. The results showed that the antibacterial properties increased with the BMH content, and the antibacterial films had strong antibacterial function when the adding amount of BMH was equal or greater than 2%. The mechanical properties firstly increased with the BMH content and then rapidly decreased. The optical properties decreased with BMH content. Taking all properties of the film into account in the study, the antimicrobial film contained 1% BMH was best.

A series of molybdates, Ag2Mo2O7 and AMoO4 (A = Zn, Co), were prepared as a new type of inorganic antibacterial agent via wet chemical routes including hydrothermal synthesis and coprecipitation reaction. The structure and morphology of the samples were characterized with X-ray diffraction and scanning electron microscopy. The anti-bacterial properties of the molybdates against Escherichia coli and staphylococcus aureus were examined, showing good antibacterial behavior.

The Doctoral Thesis has been prepared as a thematically united collection of scientific publications. It consists of a summary and five scientific publications. Publications have been written in English, their total volume is 39 pages. A new, selective class of CA IX and CA XII inhibitors – 3H-1,2-benzoxathiepine 2,2-dioxides, has been found. A series of 3H-1,2-benzoxathiepine 2,2-dioxide triazolyl, acylamino and aryl derivatives was synthesized. We discovered that furagin, a clinically used antibacterial agent, is a selective inhibitor of CA IX and CA XII. Developing this concept, we synthesized a series of imidazolidine-2,4-dione derivatives. Inhibitory activity on relevant human CA isoforms (I, II, IX, and XII) was determined for all products synthesized within the scope of the Doctoral Thesis.

Dodecyl glycerol inhibits the synthesis of the peptidoglycans of Streptococcus faecium ATCC 9790 and Streptococcus mutans BHT. This metabolic regulation represents the second known mode by which dodecyl glycerol expresses antibacterial activity. The first mode of action of dodecyl glycerol was shown to stimulate autolysin activity which degrades cell-wall peptidoglycan (Ved HS, Gustow E, Mahadevan V and Pieringer RA, 1984, J. Biol. Chem.259, 8115–8121).

Film Preparation

Antimicrobial packaging is a hot research in food packaging research. A new type of antibacterial packaging film preparation was introduced in this paper. The new composite membrane was successfully prepared by using poly (succinic acid - adipic acid - butanediol) ester (PBSA) film as the base film through surface grafted approach, and nano-silver ions were used as antimicrobial agent in the antimicrobial film. The results showed that the new PBSA film has a good antibacterial antibacterial properties, and the best antibacterial agent formulations have been identified.

Diffraction Diagram

A new type of synthetic industrial diamond formed by an explosive shock process has been recently developed by the Du Pont Company. This material consists of a mixture of two basically different forms, as shown in Figure 1: relatively flat and compact aggregates of acicular crystallites, and single crystals in the form of irregular polyhedra with straight edges.Figure 2 is a high magnification micrograph typical for the fibrous aggregates; it shows that they are composed of bundles of crystallites 0.05-0.3 μ long and 0.02 μ. wide. The selected area diffraction diagram (insert in Figure 2) consists of a weak polycrystalline ring pattern and a strong texture pattern with arc reflections. The latter results from crystals having preferred orientation, which shows that in a given particle most fibrils have a similar orientation.

I. IntroductionThermionic electron gun with the Wehnelt grid is popularly used in the electron microscopy and electron beam micro-fabrication. It is well known that this gun could get the ideal brightness caluculated from the Lengumier and Richardson equations under the optimum condition. However, the design and ajustment to the optimum condition is not so easy. The gun has following properties with respect to the Wehnelt bias; (1) The maximum brightness is got only in the optimum bias. (2) In the larger bias than the optimum, the brightness decreases with increasing the bias voltage on account of the space charge effect. (3) In the smaller bias than the optimum, the brightness decreases with bias voltage on account of spreading of the cross over spot due to the aberrations of the electrostatic immersion lens.In the present experiment, a new type electron gun with the electrostatic and electromagnetic lens is designed, and its properties are examined experimentally.
