Streptomyces ghanaensis VITHM1 mediated green synthesis of silver nanoparticles： Mechanism and biological applications

引用

Frontiers of Chemical Science and Engineering 2016年第4期10卷 542-551页

作者： Mani Abirami krishnan Kannabiran Biomolecules and Genetic Division School of Biosciences and Technology VIT University Tamil Nadu 623014 India

We present the microbial green synthesis of silver nanoparticles （hiPs） by Streptomyces ghanaensis VITHM1 strain （MTCC No. 12465）. The secondary metabolites in the cell free supernatant of this bacterium when incubated with 1 mmol/L AgNO3, mediated the biological synthesis of AgNPs. The synthesized AgNPs were characterized by UV-visible spectrum, X-ray diffrac- tion （XRD）, atomic force microscope, scanning electron microscopy equipped with energy dispersive spectroscopy, transmission electron microscopy, FT-IR spectroscopy, dynamic light scattering and zeta potential. They were highly stable and, spherical in shape with the average size of 30-50 nm. The secondary metabolites involved in the formation of AgNPs were identified gas chromatographymass spectrography. The 3D structure of the unit cell of the synthesized AgNPs was determined using XRD data base. The synthesized AgNPs exhibited significant antibacterial activity against tested bacterial pathogens, and did not show haemolysis on human red blood cells. This green synthesis could provide a new platform to explore and use AgNPs as antibacterial therapeutic agents.

控制理论与应用（英文版） 2013年第2期11卷 186-192页

作者： Ganesan ARTHI krishnan BALACHANDRAN Department of Mathematics Bharathiar University

In this paper, we establish a set of sufficient conditions for the controllability of damped second-order impulsive neutral integrodifferential systems with nonlocal initial conditions in Banach spaces. The approach used is the Sadovskii fixed point theorem combined with a noncompact condition on the cosine family of operators. An example is oresented to illustrate the result.

Review on mechanism and process of surface polishing using lasers

引用

Frontiers of Mechanical Engineering 2019年第3期14卷 299-319页

作者： Arun krishnan Fengzhou FANG Centre of Micro/Nano Manufacturing Technology (MNMT-Dublin) University College Dublin Dublin 4 Ireland State Key Laboratory of Precision Measuring Technology and Instruments Centre of Micro/Nano Manufacturing Technology (MNMT) Tianjin University Tianjin 300072 China

Laser polishing is a technology of smoothening the surface of various materials with highly intense laser beams. When these beams impact on the material surface to be polished, the surface starts to be melted due to the high temperature. The melted material is then relocated from the ‘peaks to valleys’ under the multidirectional action of surface tension. By varying the process parameters such as beam intensity, energy density, spot diameter, and feed rate, different rates of surface roughness can be achieved. High precision polishing of surfaces can be done using laser process. Currently, laser polishing has extended its applications from photonics to molds as well as bio-medical sectors. Conventional polishing techniques have many drawbacks such as less capability of polishing freeform surfaces, environmental pollution, long processing time, and health hazards for the operators. Laser polishing on the other hand eliminates all the mentioned drawbacks and comes as a promising technology that can be relied for smoothening of initial topography of the surfaces irrespective of the complexity of the surface. Majority of the researchers performed laser polishing on materials such as steel, titanium, and its alloys because of its low cost and reliability. This article gives a detailed overview of the laser polishing mechanism by explaining various process parameters briefly to get a better understanding about the entire polishing process. The advantages and applications are also explained clearly to have a good knowledge about the importance of laser polishing in the future.

作者： Bheeman RADHAkrishnan krishnan BALACHANDRAN Department of Applied Mathematics & Computational Sciences PSG College of Technology Department of Mathematics Bharathiar University

In this paper, we study the controllability results for the nonlinear impulsive integrodifferential evolution systems with time-varying delays in Banach spaces. The sufficient conditions of exact controllability is proved under without assuming the compactness of the evolution operator. The results are obtained by using the semigroup theory and the Schafer fixed point theorem.
