The maximal monotonicity of the subdifferential in locally convex spaces via upper envelopes [PDF]

arXiv, 2019
Abstract Equivalent conditions that make the convex subdifferential maximal monotone are investigated in the general settings of locally convex spaces.

Anti‐icing Performance of Superhydrophobic Surfaces with Periodic Micro‐nano Structures Directly Induced by Femtosecond Laser

Advanced Materials Interfaces, EarlyView.
This study provides a femtosecond laser etching method for preparing superhydrophobic anti‐icing surfaces, which directly induces periodic micro‐nano structures on the laser scanning path, eliminating the complicated steps of designing hydrophobic patterns.

Fast Prototyping and Ex Vivo Evaluation of Dissolvable Millineedle Patches Made by Solvent Casting from CO2 Laser Ablated Elastomer Molds

Advanced Materials Interfaces, EarlyView.
CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

On convex-cyclic operators [PDF]

arXiv, 2014
We give a Hahn-Banach Characterization for convex-cyclicity. We also obtain an example of a bounded linear operator $S$ on a Banach space with $\sigma_{p}(S^*)=\emptyset$ such that $S$ is convex-cyclic, but $S$ is not weakly hypercyclic and $S^2 $ is not convex-cyclic. This solved two questions of Rezaei in \cite{Rezaei} when $\sigma_p(S^*)=\varnothing$

Carbon Dot‐Doped Silica Xerogel Phosphors Excited by Blue LEDs and LDs for the Brilliant White Lighting of Endoscope Tips

Advanced Materials Interfaces, EarlyView.
Carbon dot‐doped silica xerogel phosphors derived by Sol–Gel method exhibit brilliant white light, making them promising candidates for next‐generation endoscopes. The approach offers a sustainable, scalable solution for the development of advanced endoscopic devices with enhanced imaging capabilities and reduced environmental impacts.

On Co-ordinated Quasi-Convex Functions [PDF]

arXiv, 2010
In this paper, we give some definitions on quasi-convex functions and we prove inequalities contain J-quasi-convex and W-quasi-convex functions. We give also some inclusions.

Wearable Electrohydraulic Actuation For Salient Full‐Fingertip Haptic Feedback

Advanced Materials Technologies, EarlyView.
This study introduces a wearable soft robotic system that combines a flat and conformable electrohydraulic pump, a mechanically transparent channel, and an ultra‐thin fingertip chamber to provide salient haptic feedback that imitates natural touch experiences.
