Size-dependent thermodynamic description of the binary Pb-Sn system [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2017 Recently, a new thermodynamic description of the binary Pb - Sn system was proposed and it seems to be interesting to extend this description on the system, where size of particles plays a key-role.

Segmentation of Images of Lead Free Solder [PDF]
, 2010 We present two approaches to segment metallic phases in images of lead free solder joints. We compare the results of a method without user interaction with another one extrapolating information from a relatively small set of user labeled pixels. The segmented images provide statistical data of spatial characteristics of phases to serve as input in ...

Advanced Engineering Materials, EarlyView.Gallium microalloying redirects interfacial reactions in low‐temperature Bi–Sn solders from Cu–Sn toward Cu–Ga intermetallic formation. The resulting Cu–Ga layer suppresses intermetallic growth during thermal aging, alters fracture pathways, and improves interfacial stability.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Effect of trace elements on the interface reactions between two lead-free solders and copper or nickel substrates [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2007 Traditional Sn-Pb solder alloys are being replaced, because of environmental and health concerns about lead toxicity. Among some alternative alloy systems, the Sn-Zn and Sn-Cu base alloy systems have been studied and reveal promising properties.

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride
Advanced Functional Materials, EarlyView.This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

A new thermodynamic description of the binary Sb-Zn system [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2014 The Sb-Zn alloys are important from technological point of view. Antimony - zinc alloys are not only part of lead-free solders but also thermoelectric materials.
