On a curvature flow model for embryonic epidermal wound healing
, 2018 The paper studies a curvature flow linked to the physical phenomenon of wound closure. Under the flow we show that a closed, initially convex or close-to-convex curve shrinks to a round point in finite time.

Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

About a generalized class of close-to-convex functions defined by q-difference operator [PDF]
Scientific Bulletin of the ''Petru Maior" University of Tîrgu Mureș, 2016 In this paper we generalize the class of close-to-convex functions by the q-difference operator, for functions with negative coefficients and we study some properties of this generalized class. An analogue of the Pólya-Schoenberg conjecture is proved.

10 Years Development of Potassium‐Ion Batteries
Advanced Materials, EarlyView.Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of

Robust Full‐Surface Bonding of Substrate and Electrode for Ultra‐Flexible Sensor Integration
Advanced Materials, EarlyView.A direct hybrid bonding method that enables both gold and parylene bonding without adhesives is developed. This technique achieves full‐surface direct bonding of electrodes and substrates in flexible electronic connections. The method offers high flexibility, stable mechanical durability, and high‐resolution interconnections, accommodating varying ...

The Coefficients of Multivalent Close-to-Convex Functions [PDF]
Proceedings of the American Mathematical Society, 1969 Inequality (1.1) reduces to the well-known Bieberbach conjecture when p =1. The conjecture was proven by Goodman and Robertson [3] for a function in S(p), in case all its coefficients are real and by Robertson [7], in case a, = a2 = ... = a,2 =0, the remaining coefficients being complex.

Advanced Materials, EarlyView.Mechanochromic hydroxypropyl cellulose (HPC) integrated with microfluidic devices creates scalable, eco‐friendly reflective color displays. We demonstrate mechanochromic displays with 500 µm pixel size and 5Hz switching rates with room for optimisation. The proposed mechanochromic HPC displays are an initial step toward more environmentally responsible

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.

Bounds on third Hankel determinant for close-to-convex functions
Acta Universitatis Sapientiae: Mathematica, 2015 In this paper, we have obtained upper bound on third Hankel determinant for the functions belonging to the class of close-to-convex functions.
