Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

Advanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and

Uniform Dentability, Uniform Smoothability and Approximations to Convex Sets

Rocky Mountain Journal of Mathematics, 1992
The author defines the notions of uniform dentability and uniform smoothability for a Banach space \(X\) and also gives their weak\(^*\) versions. Proving several technically involved lemmas, it is shown that \(X\) is uniformly (resp. \(X^*\) is weak\(^*\) uniformly) dentable if and only if \(X^*\) is weak\(^*\) uniformly smoothable (resp.

Uniformly Convex Metric Spaces

Analysis and Geometry in Metric Spaces, 2014
In this paper the theory of uniformly convex metric spaces is developed. These spaces exhibit ageneralized convexity of the metric from a fixed point.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Perception of Border Ownership by Multiple Gestalt Factors

i-Perception, 2012
Gestalt factors such as convexity, closure, and size promote the perception of the direction of figure. Although recent studies have investigated the effects of the individual factors, it has not been clarified how these factors interact with each other,

Generative Models for Crystalline Materials

Advanced Materials, EarlyView.
Generative machine learning models are increasingly used in crystalline materials design. This review outlines major generative approaches and assesses their strengths and limitations. It also examines how generative models can be adapted to practical applications, discusses key experimental considerations for evaluating generated structures, and ...

Ultrafast Photocatalytic Wettability Switching in Substrate‐Interface Tailored Titanium Dioxide Thin Films

Advanced Materials Interfaces, EarlyView.
This study demonstrates ultrafast photocatalytic wettability switching in TiO2 thin films by tailoring substrate doping and interface oxides. Enhanced switching rates and hemiwicking effects are achieved through optimized material stacks and nanostructuring.

On a Numerical Radius Preserving Onto Isometry on L(X)

Journal of Function Spaces, 2016
We study a numerical radius preserving onto isometry on L(X). As a main result, when X is a complex Banach space having both uniform smoothness and uniform convexity, we show that an onto isometry T on L(X) is numerical radius preserving if and only if ...

Best quasi-convex uniform approximation

Journal of Mathematical Analysis and Applications, 1990
Let B be the linear space of all bounded real functions f on [0,1] with the norm \(\| f\|_{\infty}=\sup_{x\in [0,1]}| f(x)|.\) The function \(g\in B\) is quasi-convex if g(x)\(\leq \max \{g(s),g(t)\}\) for all \(0\leq s\leq x\leq t\leq 1\). Let \(K\subset B\) denote the set of all quasi-convex functions on [0,1]. \textit{V. A. Ubhaya} [J. Math.
