Additive Manufacturing of Cemented Tungsten Carbide with a Cobalt-Free Alloy Binder by Selective Laser Melting for High-Hardness Applications

JOM, 2019
Cemented tungsten carbide (WC) is commonly used for wear-resistant applications, such as cutting tools and abrasives due to its extremely high hardness. This hardness leads to post-process machining of WC to be time- and cost-intensive.

Experimental Isolation of Single Impact, Cumulative Energy, Aging, and Liquid‐Assisted Grinding Effects in Mechanochemical Reactions

Angewandte Chemie, EarlyView.
An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.

IL‐4/STAT6‐signaling Influences Local Inflammation and Regeneration Processes During Acute Pancreatitis and Promotes Fibrosis by a Direct Activation of Pancreatic Fibroblasts During Chronic Pancreatitis

Advanced Science, EarlyView.
IL‐4/IL‐13/STAT6 signaling plays a crucial for the suppression of pro‐inflammation during acute pancreatitis and supports acinar cell regeneration but has only minor impact on fibrogenesis during chronic form of the disease. IL‐4/IL‐13 induce the expression of certain collagens directly in pancreatic fibroblasts via STAT6 activation, whereas ...
