Center of planar quintic quasi--homogeneous polynomial differential systems
Discrete & Continuous Dynamical Systems - A, 2015 The authors describe all planar polynomial systems of degree five which are quasi-homogeneous of type \((i,j)\), where \(i,j\) are coprime numbers satisfying \(6\geq i>j\geq 1\). There are 15 such systems, among them the only system with a (global) center is \[ \dot{x}=-3bxy^2-y^5,\;\dot{y}=by^3+x,\;\;b ...

Advanced Materials, EarlyView.Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

Electronic Journal of Differential Equations, 2015 We study the number of limit cycles that bifurcate from the periodic solutions surrounding a uniform isochronous center located at the origin of the quartic polynomial differential system $$ \dot{x}=-y+xy(x^2+y^2),\quad \dot{y}=x+y^2(x^2+y^2 ...

AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing
Advanced Materials, EarlyView.This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Limit cycles for piecewise smooth perturbations of a cubic polynomial differential center
Electronic Journal of Differential Equations, 2015 In this article, we study the planar cubic polynomial differential system $$\displaylines{ \dot{x}=-yR(x,y)\cr \dot{y}=xR(x,y) }$$ where $R(x,y)=0$ is a conic and $R(0,0)\neq 0$.

Additive Manufacture of Diamond:Titanium Hybrid Quantum Sensors
Advanced Materials Interfaces, EarlyView.ABSTRACT Additive manufacture represents one of the most advanced techniques for the creation of complex parts for applications as diverse as aerospace and implant surgery. However, a challenge with bespoke manufacture of metal parts is the incorporation of sensor elements in a fashion compatible with the 3D printing process.
