Implantable Self‐Powered Systems for Electrical Stimulation Medical Devices

Advanced Science, EarlyView.
In this paper, the design strategy and clinical application of ISS are discussed in depth from four aspects: the design and optimization of the energy collection module, the selection and preparation of adaptive electrode materials, the innovation of system design strategy, and the biological effect of electrical stimulation of ISS.

Sustainable Efficiency of Far-from-equilibrium Systems [PDF]

Interdisciplinary Description of Complex Systems, 2012
The Carnot efficiency of usual thermal motors compares the work produced by the motor to the heat received from the hot source, neglecting the perturbation of the cold source: thus, even if it may be appropriate for industrial purposes, it is not ...

Single and Double Generator Bracket Formulations of Geophysical Fluids with Irreversible Processes [PDF]

arXiv, 2018
The equations of reversible (inviscid, adiabatic) fluid dynamics have a well-known variational formulation based on Hamilton's principle and the Lagrangian, to which is associated a Hamiltonian formulation that involves a Poisson bracket structure. These variational and bracket structures underlie many of the most basic principles that we know about ...

Impact of the Sulfurized Polyacrylonitrile Cathode Microstructure on the Electrochemical Performance of Lithium–Sulfur Batteries

Advanced Science, EarlyView.
SPAN is a promising alternative sulfur cathode material for next‐generation batteries. However, the impact of the cathode microstructure on the electrochemical performance is not fully understood yet. Herein, the cathode microstructure is varied applying calendering.

A Lagrangian formalism for nonequilibrium thermodynamics [PDF]

arXiv, 2015
In this paper, we present a Lagrangian formalism for nonequilibrium thermodynamics. This formalism is an extension of the Hamilton principle in classical mechanics that allows the inclusion of irreversible phenomena in both discrete and continuum systems (i.e., systems with finite and infinite degrees of freedom).

The effects of nonlocality on the evolution of higher order fluxes in non-equilibrium thermodynamics

, 2004
The role of gradient dependent constitutive spaces is investigated on the example of Extended Thermodynamics of rigid heat conductors. Different levels of nonlocality are developed and the different versions of extended thermodynamics are classified. The

Cobalt Single‐Atom Intercalation in Molybdenum Disulfide Enhances Piezocatalytic and Enzyodynamic Activities for Advanced Cancer Therapeutics

Advanced Science, EarlyView.
The single‐atom doped molybdenum disulfide piezocatalyst markedly enhances both piezoelectric and enzyme‐mimicking activities, accelerating glutathione depletion. It induces mitochondrial dysfunction and cell cycle arrest, ultimately driving apoptosis while inactivating glutathione peroxidase 4 to initiate ferroptosis.

Thermodynamic restrictions on linear reversible and irreversible thermo-electro-magneto-mechanical processes

Heliyon, 2016
A unified thermodynamic framework for the characterization of functional materials is developed. This framework encompasses linear reversible and irreversible processes with thermal, electrical, magnetic, and/or mechanical effects coupled.

Li+ Diffusion in LinCoNb2O6 (0 < n ≤ 6) Anode with High Capacity Density: Fast Kinetics and Mechanistic Insights

Advanced Science, EarlyView.
CoNb2O6 with 6 Li+/e⁻ reaction and high theoretical capacity density of 472 mA g−1, exhibited exceptional rate capability and cycling stability, which is attributed to dual Li+ solid diffusion mechanisms, namely direct‐hopping mechanism in LinCoNb2O6 (0 ≤ n ≤ 3) and knock‐off mechanism in LinCoNb2O6 (3 < n ≤ 6).
