Direct estimate of the internal π-donation to the carbene centre within N-heterocyclic carbenes and related molecules

open access: yesBeilstein Journal of Organic Chemistry, 2015
Fifteen cyclic and acylic carbenes have been calculated with density functional theory at the BP86/def2-TZVPP level. The strength of the internal X→p(π) π-donation of heteroatoms and carbon which are bonded to the C(II) atom is estimated with the help of

Enhancement of fatigue resistance by recrystallization and grain growth to eliminate bonding interfaces in Cu–Cu joints

open access: yesScientific Reports, 2022
Cu–Cu joints have been adopted for ultra-high density of packaging for high-end devices. However, cracks may form and propagate along the bonding interfaces during fatigue tests.

Local Spin Analysis and Chemical Bonding

open access: yesChemistry – A European Journal, 2013
AbstractThe electronic structure of main‐group diatomic molecules is discussed in the light of local spin analysis. A deep investigation into the origin of local spins and their coupling is presented. It is shown that the presence of significant local spins in bonded molecules flags deviations from the classical bonding prototypes.

Continuing Bonds and Grief: A Prospective Analysis

open access: yesDeath Studies, 2006
Using data of 56 bereaved individuals, this study examined associations of various manifestations of continuing bonds, assessed at 7-12 months post-loss, with concurrent and prospective (9 months later) symptoms of grief and depression. Among other things it was found that, independent of initial symptom levels, manifestations of continuing bonds ...

Thermal Analysis of Si/GaAs Bonding Wafers and Mitigation Strategies of the Bonding Stresses

open access: yesAdvances in Materials Science and Engineering, 2017
In order to effectively reduce the thermal stresses of Si/GaAs bonding wafers during their annealing process, first of all, based on E. Suhir’s bimaterial thermal stress theory, the thermal stresses in the wafer bonding interfaces are analyzed and the ...
