Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

Advanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

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

Advanced 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.

Advanced load pull systems

IET Seminar on High Efficiency Power Amplifier Design for Next Generation Wireless Applications, 2006
Load-pull systems are very versatile characterization tools for RF power devices. The measurement results enable the quick design of highly efficient and linear power amplifiers without the need of a device model but also allow verification of developed device models under realistic stimuli.

Pulling effect in synchronized systems

Proceedings of the IEE - Part IV: Institution Monographs, 1954
Synchronization of a certain type of valve oscillator, having a low-pass filter in the synchronization loop, and also of self-starting synchronous motors is examined. Under some conditions the pulling effect takes place in these circuits, i.e. the pull-in range of synchronization is smaller than the pull-out range. The pulling function, i.e.

Active Load-Pull Systems

2013
Chapter 3 describes active load-pull techniques, their design issues, and important related characteristics. The descriptions involve two aspects: the theoretical postulations of various active load-pull methods; and, then their respective designs and features, and associated practical issues normally encountered in their practical realizations ...
