A class of fractional order systems with not instantaneous impulses

open access: yesThe Journal of Nonlinear Sciences and Applications, 2017
Summary: This paper is concerned with a kind of fractional order systems with Caputo-Hadamard derivative (of order \(q\in\mathbb{C}\) and \(\mathfrak{R}(q)\in(1,2)\)) and not instantaneous impulses. The obtained result uncovers that there exists a general solution for these impulsive systems, which means that the state trajectory of these impulsive ...

Paraborg: Paramedic Cyborg Insects for In Situ Emergency Drug‐Delivery

open access: yesAdvanced Science, EarlyView.
This work introduces Paraborg, a human‐supervised paramedic cyborg‐insect platform that combines controllable locomotion, onboard imaging, and an auto‐injection mechanism for in situ drug‐delivery. By demonstrating reliable navigation, target stabilization, injector launch, and multi‐insect teamwork, the study extends cyborg insects from survivor ...

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

open access: yesAdvanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.

Heat‐to‐Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors

open access: yesAdvanced Science, EarlyView.
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for
