We investigate femtosecond photoassociation of thermally hot atoms in the gas phase and its coherent control. In the photoassociation process, formation of a chemical bond is facilitated by light in a free-to-bound optical transition. Here, we study free-to-bound photoassociation of a diatomic molecule induced by femtosecond pulses exciting a pair of scattering atoms interacting via the van-der...

In this paper, I will look at the rather convoluted discovery process which gave birth to the concept of the shared electron pair bond as developed by G.N. Lewis, to be subsequently appropriated by the American founders of quantum chemistry, and highlight the complex relations between conceptual development and the different contexts in which ideas are created and presented. I will show how the...

We present a microscopic model for metastable Si dangling-bond defect creation in hydrogenated amorphous silicon, which is applicable to both light-induced defect creation in solar cells ~Staebler-Wronski effect! and bias-stress-induced defect creation in thin-film transistors. Light or gate bias causes electron-hole pairs or electrons, respectively, to be localized on short, weak Si-Si bonds, ...

In this work, the strength of cold roll bond of the commercially pure titanium (CP Ti) sheet and the effect of TiO2 nanoparticles on bond strength was investigated. Through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. Thus, resear...

Indole and the related heterocycles have emerged as efficient building blocks for the creation of novel anion receptors. This chapter focuses on the employment of indoles, carbazoles, and indolocarbazoles in the creation of molecular clefts, macrocycles, oligomers, and sensors. The majority of these structures utilize the heterocyclic NH as a hydrogen bond donor in binding to anions of various ...

Abstract Background and Aim: High chipping rates of the veneering porcelain of zirconia ceramic restorations have been reported in clinical studies. Thus, the shear bond strength (SBS) between the zirconia core and veneering porcelain requires investigation. Materials and Methods: In this in-vitro study, at first, using a computer-aided design/computer-aided manufacturing (CAD/CAM) machine, 1...
