Mathematical model of drug delivery using Anti-cancerous Herbal drugs

Katiyar V.K., Pathak P., Indian Institute of Technology, Roorkee, IN

Pharmacokinetics deals with the distribution of drugs, chemicals, tracers or radioactive substance among the various compartments of the human body. Compartment modeling is very convenient for biochemical transformation. In this paper, we have used basic [...]

Gatifloxacin Nanoparticles For Ophthalmic Delivery

Motwani S.K., Ahmad F.J., Iqbal Z., Talegaonkar S., Khar R.K., Faculty of Pharmacy, Hamdard University, IN

Biodegradable colloidal nanoparticles of Poly (lactide-co-glycolide) (PLGA) have received considerable attention as a possible means of delivering drugs because of their biocompatibility and resorbability through natural pathways. As the ocular efficacy of drugs is greatly [...]

Design of Magnetic Nanoparticles for Purification of His-tagged Recombinant Proteins

Mohapatra S., Pal D., Ghosh S.K., Pramanik P., Indian Institute of Technology, IN

Manipulation of proteins effectively for in-vitro study is an important step of research in the area of proteomics. The expression of recombinant proteins with histidine fusion tags(6xHis) is widely used to ease their purification from [...]

Electric field induced self-assembled nanostructures in spray deposited nanocrystalline CdX and HgX (X= Se and Te) thin films

Dutta V., RangaRao A., Indian Institute of Technology Delhi, IN

In this paper we report on electric field induced self assembled nanostructures in the spray deposited nanocrystalline CdX and HgX thin films. Nanoparticles of II-VI semiconductors (CdX, HgX; X= Se, Te) have been synthesized using [...]

Development of Mn2O3/SiO2 nanocomposite by sol-gel route

Prakash I., Muralidharan P., Nallamuthu N., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Nanocrystalline manganese oxides have been gaining importance in the fields of catalysis, electrochemistry, ion-exchange materials, magnetite, sensors, batteries, etc. An in - situ sol-gel process is investigated to synthesize uniform dispersion of the Mn2O3 nanocrystals [...]

Compact Modeling of Threshold Voltage in Nanoscale Strained-Si/SiGe MOSFETs

Nawal S., Venkataraman V., Kumar M.J., Indian Institute of Technology, IN

A simplae compact model for the threshold voltage of Strained Si/SiGe MOSFET is reported for the first time. This model accurately predicts the effects of Ge content and other device parameters on threshold voltage. The [...]

Comparison of Three Region Multiple Gate Nanoscale Structures for Reduced Short Channel Effects and High Device Reliability

Goel K., Saxena M., Gupta M., Gupta R.S., Gupta M., Gupta R.S., Professor, IN

We have modeled a new structure TRIMGAS which has 3 gate materials in the gate and an oxide stack. we have compared various parameters to see whether this strucure is superior to any of our [...]

Pandiyan J., Umapathy M., Balachandar S., Arumugam M., Ramaswamy S., Larsen & Toubro Limited, IN

This paper presents the design of an acceleration sensing transmitter using Micro Electro Mechanical System (MEMS) capacitive accelerometer. It describes the accelerometer sensor interfacing circuit, rms-to-dc converter and voltage to current loop converter circuit design, [...]

Kinetics in two Phase-Observe Interaction and Identify the Binding Parameters

Yadav V., Pandey A., University Grant Commission, IN

Kinetic and mechanistic studies of some alcohols viz., allyl, crotyl, methyl and ethyl alcohol using quinquevalent vanadium in aqueous and anionic micellar media are discussed. Oxidation follows first order kinetics with respect to [V(V)], [Substrate] [...]

Change of 7Be decay rate in exohedral and endohedral C60 fullerene

Ray A., Das J.J., Das P., Saha S.K., Das J.J., Das P., Madhavan N., Variable Energy Cyclotron Center, IN

We have measured the change of decay rate of 7Be in different environments including in atomic clusters such as fullerene C60. It has been found that the decay rate depends on the geometrical position of [...]
