Exploring 3D Printing and Electrospinning Technologies for Advanced Porous Membrane Fabrication: A Review

open access: yesAdvanced Materials Technologies, EarlyView.
This paper contrasts electrospinning and 3D printing for porous membrane fabrication, evaluating their evolution, cost, resolution, mechanical traits, and scalability. While 3D printing excels in material diversity and industrial adaptability, electrospinning achieves finer resolution and thermal resilience.

Self‐Sterilizing Face Mask Employing Enzymatic Power Generation

open access: yesAdvanced Materials Technologies, EarlyView.
Electric face mask with flexible biofuel cell integration for on‐the‐go sterilization is developed utilizing ethanol oxidation via alcohol dehydrogenase, and oxygen reduction via bilirubin oxidase. Modified face mask exhibited bacterial death rates of 40–60% at only 20 µA of electric current, easily generated by the biofuel cell continuously over hours

The Blow-Up of the Local Energy Solution to the Wave Equation with a Nontrivial Boundary Condition

open access: yesMathematics
In this study, we examine the wave equation with a nontrivial boundary condition. The main target of this study is to prove the local-in-time existence and the blow-up in finite time of the energy solution.

Computation of blowing up centers

open access: yesJournal of Pure and Applied Algebra, 2003
AbstractGiven a birational projective morphism of quasi-projective varieties f:Z→X. We want to find the ideal sheaf I over X such that the blowing up of X along I corresponds to f. In this paper we approach the problem from two directions, solving two subcases.

Modified Chemical Bath Deposition of Tin Oxide for All‐Scalable Perovskite Solar Modules

open access: yesAdvanced Optical Materials, EarlyView.
A stable and scalable chemical bath deposition method for SnOx electron transport layer is developed using PbCl2 to control hydroxide levels. The resulting films enable smooth morphology and excellent optoelectronic properties. Perovskite solar cells fabricated on these T‐SnOx layers achieve 24.5% efficiency and 1000 h operational stability.
