Subclasses of close-to-convex functions
Tamkang Journal of Mathematics, 2013 We introduce some subclasses of close-to-convex functions and obtain sharp results for coefficients, distortion theorems and argument theorems from which results of several authors follows as special cases.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries
Advanced Functional Materials, EarlyView.Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...

Torsion and ground state maxima: close but not the same
, 2015 Could the location of the maximum point for a positive solution of a semilinear Poisson equation on a convex domain be independent of the form of the nonlinearity? Cima and Derrick found certain evidence for this surprising conjecture.

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Advanced Functional Materials, EarlyView.Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

On Subclass of 𝑘-Uniformly Convex Functions of Complex Order Involving Multiplier Transformations
Abstract and Applied Analysis, 2012 We introduce a subclass of 𝑘-uniformly convex functions of order 𝛼 with negative coefficients by using the multiplier transformations in the open unit disk 𝑈={𝑧∈ℂ∶|𝑧|

Certain geometric properties of Mittag-Leffler functions
Journal of Inequalities and Applications, 2019 In this paper, some geometric properties of normalized Mittag-Leffler functions are investigated. We focus on starlikeness of order 2μ+η−1 $2\mu +\eta -1$ and convexity in the direction of imaginary axis.

Coefficient Inequalities for Strongly Close-to-Convex Functions
Journal of Mathematical Analysis and Applications, 1997 Let \(f(z)=z+a_2 z^2+a_3 z^3+ \cdots\) be a normalized, strongly close-to-convex function of order \(\alpha\) on the unit disk. This means that there exist a normalized convex univalent function \(\varphi\) and a real number \(\beta\) such that \(|\arg {f'(z) \over e^{i\beta} \varphi'(z)} |

Advanced Functional Materials, EarlyView.Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks
