A Body Conformal Ultrasound Receiver for Efficient and Stable Wireless Power Transfer in Deep Percutaneous Charging

Advanced Materials, EarlyView.
Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency

Remarks on the $Γ$-regularization of Non-convex and Non-semi-continuous Functions on Topological Vector Spaces [PDF]

Journal of Convex Analysis 19(2):467-483 (2012), 2016
We show that the minimization problem of any non-convex and non-lower semi-continuous function on a compact convex subset of a locally convex real topological vector space can be studied via an associated convex and lower semi-continuous function $\Gamma \left( h\right) $. This observation uses the notion of $\Gamma $-regularization as a key ingredient.

Toward Intrinsically Stretchable OLEDs with High Efficiency

Advanced Materials, EarlyView.
This perspective provides a systematic discussion on the challenges and solutions in designing materials for intrinsically stretchable organic light‐emitting diodes (ISOLEDs). It also highlights prospective challenges and offers insights into the development of highly efficient and stable ISOLEDs for practical applications.

Convex analysis and ideal tensegrities

Comptes Rendus. Mécanique, 2011
Abstract A theoretical framework based on convex analysis is formulated and developed to study tensegrity structures under steady-state loads. Many classical results for ideal tensegrities are rationally deduced from subdifferentiable models in a novel mechanical perspective. Novel energy-based criteria for rigidity and pre-stressability are provided,

New integral inequalities via $(α,m)$-convexity and quasi-convexity [PDF]

arXiv, 2012
In this paper, we establish some new integral inequalities for $(\alpha, m)-$convex functions and quasi-convex functions, respectively. Our results in special cases recapture known results.

Binary Electrolyte Additive‐Reinforced Interfacial Molecule Adsorption Layer for Ultra‐Stable Zinc Metal Anodes

Advanced Materials, EarlyView.
A natural binary electrolyte additive is designed to achieve an enhanced interfacial molecule adsorption layer for Zn protection via reshaping the electric double‐layer structure. Consequently, the hydrogen evolution reaction is suppressed and a robust inorganic solid electrolyte interphase is constructed for dendrite‐free Zn plating.

Cephalometrically analysis of the convexity angle

Stomatoloski glasnik Srbije, 2003
The convexity angle of facial bone structures ( N-A: A-Pg) expresses the sagittal protrusion of the maxillary part of the face compared to facial profile (the convex or concave face).The convexity angle is defined as the angle colligated by the lines N-A and A-Pg.

Impermeable and Elastic Polydimethylsiloxane Film by Parylene‐Caulking for Inflatable Soft Devices

Advanced Materials Interfaces, EarlyView.
This study investigates poly‐para‐xylylene (parylene)‐caulking of polydimethylsiloxane (PDMS) without loss of its elasticity for use in inflatable soft devices such as a pneumatic balloon actuator (PBA). This study reports updated results using time‐of‐flight secondary ion mass spectrometry and the dependence of characteristics on prepolymer ratio ...
