mp2 calculations with cc-pvtz basis set were used to analyze intermolecular interactions in f3cx···yli···nccn and f3cx···nccn···liy triads (x = cl, br; y = cn, nc) which are connected via halogen and lithium bonds. those complexes with the role of liy as halogen acceptor and lithium donor show cooperativity with energy values ranging between -1.97 and -2.92 kj mol-1. those complexes with simult...

A lithium niobate (LiNbO3)/silicon (Si) hybrid structure has been developed by the surface-activated bonding of LiNbO3 chips with gold (Au) thin film to Si substrates with patterned Au film. After organic contaminants on the Au surfaces were removed using argon radiofrequency plasma, Au-to-Au bonding was carried out in ambient air. Strong bonding at significantly low temperatures below 100◦C wi...

This study was performed to evaluate the effect of a lithium-disilicate spray-liner application on both the bond strength between zirconia cores and heat-pressed lithium-disilicate glass-ceramic veneers, and the fracture strength of all-ceramic zirconia crowns. A lithium-disilicate reinforced liner was applied on the surface of a zirconia core and lithium-disilicate glass-ceramic was veneered o...

In this chapter, we discuss a method of metallic bonding between two deposited silver layers. A diffusion bonding method has been developed that enables layer transfer of single crystal lithium niobate thin films onto silicon substrates. A silver film was deposited onto both the silicon and lithium niobate surfaces prior to bonding, and upon heating, a diffusion bond was formed. Transmission el...

Problem statement: All-ceramic materials, especially silica-based lithium disilicate and nonsilicate-based Zirconia, have become a topic of interest in the field of dentistry. It is still difficult to achieve a strong and durable resin-ceramic adhesion, especially resin-Zirconia bonding. Approach: The article reviews the current literature published in the past 5 years, focusing on the latest r...

Lithium has enhanced the operational performance of fusion devices such as: TFTR, CDX-U, FTU, T-11 M, and NSTX. Lithium in the solid and liquid state has been studied extensively in laboratory experiments including its erosion and hydrogen-retaining properties. Reductions in physical sputtering up to 40– 60% have been measured for deuterated solid and liquid lithium surfaces. Computational mode...

The molecular dynamics (MD) computer simulation technique has been used to study the structure of lithium aluminosilicate (LAS) glasses and the diffusion of lithium ions. Five kinds of lithium aluminosilicate glasses with different R (ratio of the concentration of Al to Li) values are simulated. The structural features of the simulated glasses are analyzed using Radial Distribution Functions (R...

Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...

A facile and low-cost strategy is demonstrated for preparing MnO/C-N hybrid, in which the MnO nanoparticles chemically combine with N-doped C by Mn-N bonding to achieve the hybridization of MnO with N-doped C. When served as an anode in lithium ion batteries (LIBs), the resultant hybrid manifested high capacity, excellent cyclability, and superior rate capability. A lithium storage capacity of ...

Lithium-sulfur batteries show advantages for next-generation electrical energy storage due to their high energy density and cost effectiveness. Enhancing the conductivity of the sulfur cathode and moderating the dissolution of lithium polysulfides are two key factors for the success of lithium-sulfur batteries. Here we report a sulfur host that overcomes both obstacles at once. With inherent me...
