Advanced Science, EarlyView.An efficient N2 fixation photocatalyst, Ru‐WO3−x/CoOx, is prepared by integrating respective reduction and oxidation sites onto a plasmonic semiconductor. Owing to optimized reaction kinetics and promoted charge carrier separation by the synergistic effect between the two types of active sites, the involved reduction and oxidation half‐reactions are ...

Impulsive evolution inclusions with state-dependent delay and multivalued jumps
Electronic Journal of Qualitative Theory of Differential Equations, 2013 In this paper we prove the existence of a mild solution for a class of impulsive semilinear evolution differential inclusions with state-dependent delay and multivalued jumps in a Banach space.

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives
Advanced Electronic Materials, EarlyView.The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Non-smooth modelling of electrical systems using the flux approach [PDF]
, 2018 The non-smooth modelling of electrical systems, which allows for idealised switching components, is described using the flux approach. The formulations and assumptions used for non-smooth mechanical systems are adopted for electrical systems using the ...

Advanced Energy and Sustainability Research, EarlyView.Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Filippov's theorem for impulsive differential inclusions with fractional order
Electronic Journal of Qualitative Theory of Differential Equations, 2009 In this paper, we present an impulsive version of Filippov's Theorem for fractional differential inclusions of the form: $$ \begin{array}{rlll} D^{\alpha}_*y(t) &\in& F(t,y(t)), &\hbox{ a.e. } \, t\in J\backslash \{t_{1},\ldots,t_{m}\},\ \alpha\in(1,2]

Consistent Approximations to Impulsive Optimal Control Problems
, 2016 We analyse the theory of consistent approximations given by Polak and we use it in an impulsive optimal control problem. We reparametrize the original system and build consistent approximations for this new reparametrized problem.

Assessing the Impact of Promotions on Consumer Purchasing Behavior During Crises
Agribusiness, EarlyView.ABSTRACT Understanding how households modify their food expenditure decisions during times of crisis is essential because consumer purchasing behavior frequently changes during these times. This study looks at these behavioral shifts during the COVID‐19 pandemic, concentrating on how price sensitivity and response to sales promotions changed over the ...
