Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Ricci-Bourguignon solitons on sequential warped products

, 2023
We study Ricci-Bourguignon solitons on sequential warped products. The necessary conditions are obtained for a Ricci-Bourguignon soliton with the structure of a sequential warped product to be an Einstein manifold when we consider the potential field as ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

Advanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

A General Inequality for CR-Warped Products in Generalized Sasakian Space Form and Its Applications

Advances in Mathematical Physics, 2021
In the present paper, by considering the Gauss equation in place of the Codazzi equation, we derive new optimal inequality for the second fundamental form of CR-warped product submanifolds into a generalized Sasakian space form.

A Pinching Theorem for Compact Minimal Submanifolds in Warped Products $I{\times }_f{\mathbb{S}}^m\left(c\right)$

Mathematics, 2020
Let Sm(c) be a Euclidean sphere of curvature c>0 and R be a Euclidean line. We prove a pinching theorem for compact minimal submanifolds immersed in Riemannian warped products of the type I×fSm(c), where f:I→R+ is a smooth positive function on an open ...

Stable Minimal Surfaces in Riemannian Warped Products [PDF]

, 2017
We obtain several stability results forminimal two-sided surfaces immersed in a wide class of 3-dimensional Riemannian warped products, which includes the class of Riemannian products. As a consequence, some Bernstein-type results are provided. Moreover,
