The density functional theory (DFT)-based quantum-chemical calculations have been performed on di-n-butyltin(IV) derivative of glycylphenylalanine (H2L) using the Gaussian 09 software package. The molecular geometry of n-Bu2SnL was optimized at B3LYP/6-31G(d,p)/LANL2DZ(Sn) level of theory without any symmetry constraint. The harmonic vibrational fr...

A two step Adomian decomposition method (TSADM) coupled with pade approximations is applied for solving various two-point boundary value problems with initial conditions. This technique is based on a new definition of the Adomian polynomials and the TSADM. A Maple package ADMP is used to implement the proposed algorithm. The algorithm does not requ...

Attempts have been made to introduce ruled surfaces generated from any vector X, Bishop Darboux vector and Bishop vectors. Some properties with respect to developable and minimal and the relations between the integral invariants of these surfaces are discussed. Also the fundamental forms, geodesic curvatures, normal curvatures and geodesic torsions...

Implants made of AISI 316L stainless steel enjoy promising position because of their higher strength as compared to polymer based materials, and higher toughness as compared to the ceramic based implant. However, AISI 316L based implants often fail due to wear, corrosion, fatigue and bacterial infection in the human body. As most of the failures de...

Laser, a high intensity, precise, flexible and clean heat source is used as a manufacturing tool in several industrial sectors. With the advent of more robust, energy efficient, cheaper and low footprint lasers such as fiber lasers, laser based manufacturing is increasing rapidly. Laser based processes can be classified into macro processes (cuttin...

In this article, we give an overview on the complexity of ionic liquid (IL) as revealed by recent femtosecond up-conversion, molecular dynamic simulation and single molecule spectroscopy. We also demonstrate that IL may be used to generate gold nano-clusters (Au-NCs) in situ in a live cell for cell imaging.
