The behavior of an enediyne photoswitch is modulated with halogen bonding, coordinative bonding and hydrogen bonding.

This work addresses important post-packaging issues for microsystems and recommends specific research directions by localized heating and bonding. Micropackaging has become a major subject for both scientific research and industrial applications in the emerging filed of microelectromechanical systems (MEMS). Establishing a versatile post-packaging process not only advances the field but also sp...

In this letter, we present a sapphire direct bonding method using plasma surface activation, hydrophilic pre-bonding, and high temperature annealing. Through the combination of sapphire inductively coupled plasma etching and the direct bonding process, a vacuum-sealed cavity employable for high temperature applications is achieved. Cross-sectional scanning electron microscopy (SEM) research of ...

Wire bonding is a process that is used to form solid-state bonds to interconnect metals such as gold wires to metalized pads deposited on silicon integrated circuits. Typically, there are 3 main wire bonding techniques; Thermo-compression, Ultrasonic and Thermosonic. This experiment utilizes thermosonic bonding which applies heat, ultrasonic energy and force on an Au-Al system. Sixteen groups o...

Mono- and diplatinum plumbylene complexes are prepared in which the bonding comprises synergic σ donation between the Pt and Pb atoms. The bonding distinguishes the complexes from both the classical Fischer carbene bonding model and M→Pb dative-only bonding. The Pt-Pb bond of the monoplatinum complex is stable, while the diplatinum complex reversibly loses one Pt fragment.

An accurate measurement of the bonding energy an interface is important in many areas applied research. We present a novel method for measuring energy, which based on principle non-planar direct bonding, i.e., originally planar wafers onto substrates. discuss detail advantages and disadvantages compared to commonly used double cantilever beam method. To demonstrate practical relevance, by using...
