Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

Advanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.

[Assessment of cytotoxicity and biosafety of polyphenolic extracts from olive pits].

Nutricion hospitalaria, 2015
The olive tree is a source of bioactive compounds, both its fruit and its by-products. Some of its compounds have shown health benefits, being objective of this work the evaluation of biosafety in-vitro and in vivo of extracts of olive stones rich in polyphenols.He has been evaluated for cytotoxicity by addition of lyophilized extract dissolved in PBS ...

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

The Effect of Polyphenol Extraction on Enzyme Degradation of Bordered Pit Tori

, 2007
Extraction of polyphenols from the heartwood of loblolly pine, Fraser fir, and red spruce, followed by pectinase and cellulase treatments, resulted in the removal of chemical constituents and the creation of openings in the torus of bordered-pit ...
