Structural, elastic, and electronic properties of newly discovered Li2PtSi3 superconductor: Effect of transition metals

, 2016
First-principles calculations within the density functional theory (DFT) with GGA-PBE exchange-correlation scheme have been employed to predict the structural, the elastic and the electronic properties of newly discovered lithium silicide superconductor,

Elastic energy of proteins and the stages of protein folding

, 2009
We propose a universal elastic energy for proteins, which depends only on the radius of gyration $R_{g}$ and the residue number $N$. It is constructed using physical arguments based on the hydrophobic effect and hydrogen bonding.

The effect of some technological production variables on mechanical and physical properties of particleboard manufactured from cotton (Gossypium hirsutum) stalks

Maderas: Ciencia y Tecnología, 2016
The current study aims to improve properties of particleboard manufactured from cotton (Gossium hirsutum) stalks glued with urea formaldehyde. To this aim, panel density (at three levels: 0,5; 0,65 and 0,8 g/cm3), press temperature (at two levels: 150 ...

Shear bond strength and internal adaptation of lithium disilicate veneers luted to enamel using three different luting agents

Journal of Baghdad College of Dentistry
Background: Lithium disilicate veneers rely on both strong resin–ceramic bonding and intimate adaptation for long term success. Universal adhesives containing 10-Methacryloyloxydecyl Dihydrogen Phosphate may enhance the performance of contemporary resin

Integrated Circuit Bonding Distance Inspection via Hierarchical Measurement Structure

Sensors
Bonding distance is defined by the projected distance on a substrate plane between two solder points of a bonding wire, which can directly affect the morphology of the bonding wire and the performance between internal components of the chip.

Understanding the Molecular Mechanism of the Rearrangement of Internal Nitronic Ester into Nitronorbornene in Light of the MEDT Study

Molecules, 2019
The characterization of the structure of nitronic esters and their rearrangement into nitronorbornene reactions has been analyzed within the Molecular Electron Density Theory (MEDT) using Density Functional Theory (DFT) calculations at the B3LYP/6-31G(d)

A New Phenomenon: Sub-Tg, Solid-State, Plasticity-Induced Bonding in Polymers

, 2015
Polymer self-adhesion due to the interdiffusion of macromolecules has been an active area of research for several decades [70, 43, 62, 42, 72, 73, 41]. Here, we report a new phenomenon of sub-Tg, solid-state, plasticity-induced bonding; where amorphous ...

Active Colloidal Molecules

, 2018
Like ordinary molecules are composed of atoms, colloidal molecules consist of several species of colloidal particles tightly bound together. If one of these components is self-propelled or swimming, novel "active colloidal molecules" emerge.

Individual Enforcement Rights in International Sovereign Bonds [PDF]

SSRN Electronic Journal, 2008
Sovereign bond contracts are notoriously hard to enforce. The few rights that bondholders have can be vested either collectively or individually. It seems that investors traditionally had a preference for the latter, which hindered financial market reform projects, such as the universal adoption of collective action clauses or trust structures.
