Abstract: In my talk I will show my work related to the development of a new class of protein-based functional and dynamic nano-conjugated systems based on the molecular integration of structurally and functionally compatible polymer surfactants. I will show how the accessibility of reactive amino acid side chains present on the surface of globular proteins provides a spatially organized chemical platform for integrating hybrid components that can then be used to tune various biomaterial properties via site-specific surface functionalization.

Abstract: The first step in the treatment of any pathological condition is its diagnosis. Currently most medical diagnostic tests are conducted in centralized labs using bulky and expensive instruments that require trained users to operate. This infrastructure-heavy model of acquiring medical diagnostic information restricts access to proper medical diagnosis for many especially in the developing world.

Abstract: Protein aggregation plays major role in many aspects ranging from food material and health science. Globular proteins aggregates at low pH and their self-assembly causes the formation of amyloid like protein fibrils. We investigated snapshots of the fibrillation and aggregation kinetics of multi-stranded β-lactoglobulin amyloid protein fibrils by combining scattering (SANS DLS DDLS) as well as atomic force microscopy (AFM).

Abstract: Stochastic programming problems are very difficult to solve as they involve optimization as well as uncertainty analysis. Algorithms for solving large-scale nonlinear stochastic programming problems are very few in number as are the engineering applications of these problems. This seminar introduces an algorithm for large-scale stochastic nonlinear problems for both open equation systems and black box models. This algorithm is the Better Optimization of Nonlinear Uncertain Systems (BONUS) algorithm.

Abstract: Development of microscale equipment is mainly focused on reaction mixing and heat transfer; however for implementation in the process industry also separation is required. In particular equipment is missing that suits (i) the integration in a full-flow chain (ii) and production capacities of kilo- and pilot-labs in industry which amounts to product- and solvent flows of 1-10 kg/day and 10-100 l/day.

Abstract: Quality of the environment is a serious concern all over the world. Stringent emission regulations are being imposed by several countries to reduce the harmful emissions from mobile and stationary sources. Monolithic catalysts have been widely used for air pollution abatement due to their several advantages such as high heat and mass transport rates per unit pressure drop smaller transverse temperature gradients and ease of scale-up.

Abstract: Part-I: Shrinking reserves of fossil fuel decreasing quality of minerals and increasingly stringent climate policies have led to the complication of energy mix which can sustain the economic growth of the society with minimum adverse effect on the environment. Thermodynamic analysis has been used for enhancing the resource use and reducing environmental impact for many national economies.

Abstract: Unique characteristics of the nanoscale object drawn the attention of research community to create novel properties and look for possibilities to solve world’s arising problems ranging from hunger to medicine.In the present research work nanomaterials ranging from metal and metal oxide to advanced graphene nanostructure were synthesized with independent control over shape size composition surface properties and crystal phase using aerosol sol-gel and biosynthesis approaches.

Abstract: Development and mainstreaming of Sustainable Technology- End use Packages (STEPs) has been an important stream of work in supporting sustainable development in the long run. The talk is an elaboration of challenges experienced by the speaker in developing and mainstreaming STEPs divided broadly under the categories: solar heating and natural cooling; small micro and rural enterprises; small power; and waste utilization.

Abstract: Lattice Boltzmann method(LBM) is an attractive alternate to conventional computational fluid dynamics both for hydrodynamics and for gaseous microflow. In this talk I will review this method and argue that lattices used in LBM are sub-optimal and better choices do exist. I will present a new framework for Lattice Boltzmann method(LBM) which is based on sampling ideas on crystals. I will utilize the new framework and show that with appropriate choice of lattices LBM with accuracy similar to spectral method can be constructed.
