Advances in Materials Science and Engineering, 2018 Weld solidification crack prevention in the laser penetration welding process is essential for the strength of the welded component. The formation of solidification cracks can ultimately be attributed to welding residual stresses, and preventive measures

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
Advanced Functional Materials, EarlyView.A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

A Markov's theorem for extended welded braids and links [PDF]
arXiv, 2017 Extended welded links are a generalization of Fenn, Rim\'{a}nyi, and Rourke's welded links. Their braided counterpart are extended welded braids, which are closely related to ribbon braids and loop braids. In this paper we prove versions of Alexander and Markov's theorems for extended welded braids and links, following Kamada's approach to the case of ...

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis
Advanced Functional Materials, EarlyView.The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Historical overview on Vacuum suitable Welding and fatigue resistance in Research Devices [PDF]
arXiv, 2014 New inventions change the approach of vacuum suitable welding for research purpose. With orbital welding, laser welding and robot welding the possibilities increase to fabricate larger vessels more accurately. Despite this development there is still no perfect understanding on how to avoid virtual leaks and how to make such joints suitable for dynamic ...

Influence of Hysteresis on Magnetocaloric Performance at Cryogenic Temperatures: A Tb3Ni Case Study
Advanced Functional Materials, EarlyView.The existence of an inverse magnetocaloric effect in metamagnetic materials at cryogenic temperatures is investigated using multiple methods. Contrary to predictions from magnetization data, neither specific heat nor pulsed‐field measurements show such a cooling effect, instead indicating irreversible heating.
