2Combustion characteristic and aging behavior of bimetal thermite powders显示文摘Nanothermites have been employed as fuel additives in energetic formulations due to their higher energy density over CHNO energetics. Nevertheless, sintering and degradation of nanoparticles significantly limit the practical use of nanothermites. In this work, combustion characteristic and aging behavior of aluminum/iron oxide(Al/Fe2O3) nanothermite mixtures were investigated in the presence of micron-scale nickel aimed to produce bimetal thermite powders. The results showed that the alumina content in the combustion residue increased from 88.3% for Al/Fe2O3 nanothermite to 96.5% for the nanothermite mixture containing 20 wt% nickel. Finer particle sizes of combustion residue were obtained for the nanothermite mixtures containing nickel, indicative of the reduced agglomeration. Both results suggested a more complete combustion in the bimetal thermite powders. Aging behavior of the nanothermite mixture was also assessed by measuring the heat of combustion of the mixture before and after aging process. The reduction in heat of combustion of nanothermite mixtures containing nickel was less severe as compared to a significant decrease for the nanothermite mixture without nickel, indicating better aging resistance of the bimetal thermite powders.Hong-qi Nie Hay Yee Chan Sreekumar Pisharath Huey Hoon Hng 2021Defence Technology(防务技术)2021,17,3:5

4Review:Recent advances in nonlinear control technologies for shape memory alloy actuators显示文摘This paper reviews recent developments in nonlinear control technologies for shape memory alloy (SMA) actuators in robotics and their related applications. SMA possesses large hysteresis, low bandwidth, slow response, and non-linear behavior, which make them difficult to control. The fast response of the SMA actuator mostly depends upon, (1) type of controller, (2) rate of addition and removal of heat, and (3) shape or form of the actuator. Though linear controllers are more desirable than nonlinear ones, the review of literature shows that the results obtained using nonlinear controllers were far better than the former one. Therefore, more emphasis is made on the nonlinear control technologies taking into account the intelligent controllers. Various forms of SMA actuator along with different heating and cooling methods are presented in this review, followed by the nonlinear control methods and the control problems encountered by the researchers.SREEKUMAR M.

5Emerging industrial applications of microalgae:challenges and future perspectives显示文摘Microalgae are unicellular photosynthetic organisms that have been recently attracted potential interests and have applications in food,nutraceuticals,pharmaceuticals,animal feed,cosmetics,and biofertilizers industry.Microalgae are rich in a variety of high-value bioactive compounds which have potential benefits on human health and can be used for the prevention and curing of many disease conditions.But scale-up and safety issues remain a major challenge in the commercialization of microalgal products in a cost-effective manner.However,techniques have been developed to overcome these challenges and successfully selling the products derived from microalgae as food,cosmetics and pharmaceutical industries.Microalgae are rich in many nutrients and can be used for the production of functional food and nutraceuticals,safety and regulatory issues are major concerns and extensive research is still needed to make microalgae a commercial success in the future.Many practical difficulties are involved in making the microalgal food industry commercially viable.The present review focuses on the industrial applications of microalgae and the challenges faced during commercial production.Aswathy Udayan Ashutosh Kumar Pandey Pooja Sharma Nidhin Sreekumar Sunil Kumar 2021Systems Microbiology and Biomanufacturing2021,1,4:2

7Does black hole spin play a key role in the FSRQ/BL Lac dichotomy?显示文摘Blazars are characterized by large intensity and spectral variations across the electromagnetic spectrum It is believed that jets emerging from them are almost aligned with the line-of-sight. The majority of identified extragalactic sources in γ-ray catalogs of EGRET and Fermi are blazars. Observationally,blazars can be divided into two classes: flat spectrum radio quasars(FSRQs) and BL Lacs. BL Lacs usually exhibit lower γ-ray luminosity and harder power law spectra at γ-ray energies than FSRQs. We attempt to explain the high energy properties of FSRQs and BL Lacs from Fermi γ-ray space telescope observations. It was argued previously that the difference in accretion rates is mainly responsible for the large mismatch in observed luminosity in γ-ray. However, when intrinsic luminosities are derived by correcting for beaming effects, this difference in γ-ray luminosity between the two classes is significantly reduced. In order to explain this difference in intrinsic luminosities, we propose that spin plays an important role in the luminosity distribution dichotomy of BL Lacs and FSRQs. As the outflow power of a blazar increases with increasing spin of a central black hole, we suggest that the spin plays a crucial role in making BL Lac sources low luminous and slow rotators compared to FSRQ sources.Debbijoy Bhattacharya Parameswaran Sreekumar Banibrata Mukhopadhyay Ishan Tomar 2016Research in Astronomy and Astrophysics2016,16,4:2
8Lipid enhancement in microalgae by temporal phase separation:Use of indigenous sources of nutrients显示文摘Microalgae have been recommended as superior candidate for fuel production because of their advantages of higher photosynthetic efficiency, biomass & lipid productivity, and faster growth rate as compared to other energy crops. To meet up all these criteria, we have developed a continuous outdoor micro-algal raceway pond reactor(RPR) and a lab scale indoor tubular photo bioreactor(PBR) for biofuel production. An attempt to utilise indigenous sources of nutrients to improve the economics also revealed that micro-algal culturing can also be used as a mode of nutrient removal and water treatment. The photosynthetic rate and lipid production were enhanced by arresting daytime cell division and promoting night-time cell division. A 50% lipid improvement was observed for the particular algal consortia. Microscopic studies revealed that temporal phase separation could be achieved by adjusting nutrient distribution pattern. To monitor temporal phase separation, it is required to know DNA multiplication model. Quantification of g DNA in RPR confirmed that cell division happens during the night which positively affects the photosynthetic efficiency and lipid productivity of microalgae.Nidhin Sreekumar Ajit Haridas G.S.Godwin N.Selvaraju 2018Chinese Journal of Chemical Engineering2018,26,1:2
