Laser Welding and Syncristallization Techniques Comparison: In Vitro Study

International Journal of Dentistry, 2012
Background. Laser welding was first reported in 1967 and for many years it has been used in dental laboratories with several advantages versus the conventional technique. Authors described, in previous works, the possibility of using also chair-side Nd :

Self‐Soldering, Stretchable and Self‐Healing Liquid Metal Elastomer Interconnections for Soft Electronics Platforms

Advanced Materials Technologies, EarlyView.
A self‐healing and electrically conductive liquid metal elastomer enables robust self‐soldering of surface mount devices for soft electronics. Photothermally activated conductive pathways, strong pressure‐sensitive adhesion, and stable package‐integrated contacts provide high conductivity and extreme stretchability.

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors

Advanced Materials Technologies, EarlyView.
This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Laser-Based Glass Soldering

Journal of Welding and Joining, 2009
최근 산업계의 다양한 분야에서 유리 기판들을 적층하고 부착하는 기술을 활용하고 있으며, 특히 디스플레이 기기 및 염료감응형 태양전지 소자에 활용이 되기 시작하였다. 디스플레이 기기는 통신, 정보, 가전의 모든 전자산업의 약 10%이상의 위상을 차지하고 있는 분야이며 염료감응형 태양전지는 차세대 태양전지로서 건물의 창에 설치가 가능하여 BIPV 소재로서 주목을 받고 있다. 그러나 이들 소자에 있어서 유기물 기반의 재료 사용량이 점차 늘어남에 따라 새로운 유리의 접합접합에 관한 연구가 진행되고 있으며 특히 Frit을 이용한 유리의 접합공정이 각광을 받고 ...

Electric‐Current‐Induced Phase Transformation in Cu6Sn5 Below Its Equilibrium Transition Temperature

Advanced Science, EarlyView.
Electric current induces a monoclinic‐to‐hexagonal phase transformation in Cu6Sn5 at a measured bulk temperature of ∼120°C, below the equilibrium transition temperature. Ex situ synchrotron x‐ray diffraction, TEM, and matched thermal controls show that current stressing promotes the formation of a retained hexagonal η‐phase post‐stress state not ...
