Principles of Soldering serves as a problem-solving guide for engineers who work with soldering processes and soldered components and assemblies. It begins with a review of key process parameters, including surface energy and tension, wetting and contact angle, fluid flow, filler spreading characteristics, dissolution of parent materials, and intermetallic growth. It then examines the factors that influence the functional integrity of soldered joints and the practicality of the process employed. It discusses the metallurgy of solder alloy systems, the effect of metallic impurities, and the use of phase diagrams to better understand and control the soldering process. It explains how joining atmospheres influence chemical reactions and how fluxes help remove surface oxides and other films. It describes the benefits of fluxless soldering and the role of materials in defining process constraints. It also covers lead-free solders, bump bonding, amalgams, and diffusion soldering as well as mechanical property testing, joint characterization and modeling techniques, and solderability standards.

Molecular hydrogen is widely considered as a potential carbon-free and renewable energy carrier for a sustainable energy strategy. Carbon nanotubes are widely promoted as metal-free catalysts – however, we show that the metallic impurities drive hydrogen production.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
