In this study, a two-dimensional thermoelastic problem under hyperbolic heat conduction theory with an internal heat source is considered. The general solution for the temperature field, stress components and displacement field are obtained using the reduced differential transform method. The stress and displacement components are obtained using the thermal stress function in the reduced differential transform domain. All the solutions are obtained in the form of power series. The special case with a time-dependent laser heat source has been considered. The problem is considered for homogeneous material with finite rectangular cross-section heated with a non-Gaussian temporal profile. The effect of the heat source on all the characteristics of a material is discussed numerically and graphically for magnesium material taking a pulse duration of 0.2 ps. This study provides a powerful tool for finding the solution to the thermoelastic problem with less computational work as compared to other methods. The result obtained in the study may be useful for the investigation of thermal characteristics in engineering and industrial applications.
Ultrasound assisted Laccase catalyzed degradation of Ciprofloxacin hydrochloride
Rahul S. Sutar,Virendra K. Rathod 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.31 No.-
This work reports a novel technique of laccase catalyzed degradation of Ciprofloxacin hydrochloride inan ultrasound assisted process. Parameters such as enzyme loading, temperature, agitation, power, dutycycle and frequency are studied along with identification of intermediates. Maximum Ciprofloxacinhydrochloride degradation of 51% was achieved at 0.02% (w/v) enzyme loading, 60 8C temperature,power input 75 W, 22 kHz frequency, 50% duty cycle and agitation 200 rpm. As compared toconventional method, this technique not only increases Ciprofloxacin hydrochloride degradation butalso reduces degradation time. Ultrasonication with stirring shows an improved degradation which canbe used for other pharmaceuticals.

The work investigates the development andoptimization of chitosan-alginate beads containing Losartanpotassium (LP) through ionotropic/external gelationtechnique using 32 factorial design. The effect of polymerblendconcentrations i.e. chitosan and sodium alginate onthe drug encapsulation efficiency (DEE%), and cumulativedrug release after 20 h (R20h %) was optimized. The DEE%of all these beads was within the range of 67.12 ±1.97–89.81 ± 1.52 % with sustained in vitro drug releaseof 80.98–97.13 % over 20 h. The in vitro drug release fromthese beads was followed first order kinetic model. Thebeads were also characterized by FE-SEM, FTIR and XRDanalysis. The swelling of chitosan–alginate beads containingLP were influenced by the pH of the test medium. Chitosan coated alginate beads were developed as oralsustained delivery carriers for LP in order to improvepatient compliance, to reduce side effects associated with itand also to reduce the dose/dosing frequency in the managementof hypertension.

<P><B>Abstract</B></P> <P>Anti-icing coating is one of the recent hot topics in industrial applications as well as from the academic viewpoint. Icing is one of the major problem on various substrates such as glass windows in buildings as well as vehicles, solar panels, wind turbine blades, airplanes, transmission lines, power towers, traffic signals, off-shore oil platforms, telecommunication antennas, and many others. Ice accumulation can significantly reduce the performance of the substrates and results in poor visibility. Recently, considerable attention is being paid on the naturally inspired superhydrophobic/icephobic surfaces by mimicking its surface property for the development of artificial self-cleaning superhydrophobic and ice-phobic surfaces. A good example is the lotus leaf surface where hierarchical micro and nano-scale rough structure covered by low surface energy coating layer on the leaf can repel water droplets and prevent ice accumulation. On superhydrophobic surfaces, impacting and condensed water droplets rolled off before freezing at subzero temperature. On the other hand, in slippery liquid-infused porous surface (SLIPS), the air pockets are replaced by immiscible lubricant film which can easily remove the accumulated ice without any damage to the surface. In this review article, we describe the recent progress in passive anti-icing coating materials and methodologies. Metal substrates, polymers, and nanoparticles/polymer composites are playing the major role in the development of anti-icing surface. So, the main goal of this review articles deals with the development of various synthetic routes of superhydrophobic anti-icing coating materials from metal substrates, polymers, and nanoparticles/polymer composites. In addition, the role of SLIPS in anti-icing coating and their use are also discussed.</P> <P><B>Highlights</B></P> <P> <UL> <LI> This review article explores the recent developments done in fabricating the anti-icing surfaces. </LI> <LI> Various new ideas, materials, fabrication techniques and prospects are thoroughly discussed. </LI> <LI> The merit/demerits of various anti-icing surfaces were identified and discussed. </LI> <LI> This review article is beneficial for graduate, post-graduate students and experts in this research field. </LI> </UL> </P>
