Heat exchanger and method of making [PDF]

open access: yes, 1980
A heat exchange of increased effectiveness is disclosed. A porous metal matrix is disposed in a metal chamber or between walls through which a heat-transfer fluid is directed.

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Transfer of metal ions in the soil-root interface: influence of copper(II) on the stability of the fibrils [PDF]

open access: yes, 1990
A network of Ca-polygalacturonate arranged in fibrils similar to those of plant roots (Gessa C. and Deiana S., (1990); C.Gessa and Deiana S., (1990)) constitutes a very useful model far the study of the ionic transfer both in the soil-root interface ...

Enabling Digital Continuity in Virtual Manufacturing for Eco‐Efficiency Assessment of Lightweight Structures by Means of a Domain‐Specific Structural Mechanics Language: Requirements, Idea and Proof of Concept

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents a solver‐agnostic domain‐specific language (DSL) for computational structural mechanics that strengthens interoperability in virtual product development. Using a hierarchical data model, the DSL enables seamless exchange between diverse simulation tools and numerical methods.

Small extracellular vesicles contain metals and transfer metal intercellularly

open access: yesJournal of Extracellular Biology
AbstractCells have developed a highly regulated system for the uptake, transport, utilization, storage, and export of metals, ensuring the maintenance of cellular homeostasis. Small extracellular vesicles (sEVs) function as a mechanism through which a cell can export its cargo and transfer it to recipient cells.

Investigating the Effects of Build Height on Mechanical Behavior of Large‐Scale Laser Wire Directed Energy Deposited Nickel Titanium Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
Laser wire directed energy deposition process was leveraged to fabricate large scale NiTi alloy wall. Evaluation of build‐height‐dependent tribo‐mechanical properties revealed significant differences in location specific sample characteristics. The middle region achieved optimal performance (superior wear resistance, balanced strength‐ductility ...
