An Analysis Regarding the Variation of Necessary Force by the Indirect Extrusion Processes

Procedia Technology, 2014
AbstractIn comparison with other working procedures of hollow parts, indirect extrusion is characterized by high precision and productivity. Efficiency of the process imposed intense theoretical and experimental research over the years, resulting in widening the range of products manufactured [2,4–6,16].

Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

Advanced Science, EarlyView.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...

Nucleation Kinetics Reveals a Distinct Biological Function Space of Biomolecular Condensates

Advanced Science, EarlyView.
This study utilizes microfluidics to quantify the nucleation rates of dense liquid phases within dilute solutions and of the reverse process, in which dilute voids nucleate inside condensates. The interfacial tension is identified as the key determinant of both processes.

Indirect Enhancement of ALD Thin-Film Properties Induced by the ECAP Modification of an As-Extruded Mg-Ca Alloy

Micromachines
The purpose of this study is to investigate the indirect effects on the properties of ZrO2 films deposited by atomic layer deposition (ALD) when an Mg-Ca alloy is modified through equal-channel angular pressing (ECAP) following extrusion.

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Solid‐Like yet Reconfigurable 3D‐Printed Liquid Tubular Wires From Nonconductive Molecules

Advanced Science, EarlyView.
This work shatters the current reliance of liquid electronics on intrinsically conductive materials by introducing a novel interfacial redox strategy that transforms non‐conductive molecules into high‐performance, 3D liquid tubular wires with solid‐like electrical properties and exceptional reconfigurability. It opens a vast design space for all‐liquid

Dual Physiological Barriers Bypassed by a Silk‐Based Supramolecular Protein Delivery Platform for Neuroinflammation Mitigation in Alzheimer's Disease

Advanced Science, EarlyView.
A supramolecular nanocomplex based on phenolic‐modified silk sericin is developed to deliver antioxidant enzymes across the blood–brain barrier and escape lysosomal degradation. This dual‐barrier‐crossing system reduces neuroinflammation and improves cognitive performance in Alzheimer's disease mouse model, offering a promising strategy for protein ...
