High Energy Density in Combination with High Cycling Stability in Hybrid Supercapacitors [PDF]

ACS Applied Materials & Interfaces, 2022
Hybrid supercapacitors are considered the next-generation energy storage equipment due to their superior performance. In hybrid supercapacitors, battery electrodes need to have large absolute capacities while displaying high cycling stability.

Perspective on cycling stability of lithium‐iron manganese phosphate for lithium‐ion batteries [PDF]

Rare Metals, 2022
Lithium-iron manganese phosphates (LiFexMn1−xPO4, 0.1 < x < 0.9) have the merits of high safety and high working voltage. However, they also face the challenges of insufficient conductivity and poor cycling stability.

Thermal cycling stability of ultrafine-grained TiNi shape memory alloys processed by equal channel angular pressing [PDF]

Scripta Materialia, 2012
The thermal cycling stability of martensitic transformation in two different TiNi alloys processed by equal channel angular pressing (ECAP) was investigated.

Conditions on cycles for the stability of networks

2015 54th IEEE Conference on Decision and Control (CDC), 2015
We present a new local method for checking the stability of a matrix when the matrix is viewed as a weighted directed graph. The method involves checking only the cycles of the graph, and can be applied to the companion matrix of a network to check stability of the network.

On the local stability of limit cycles

Chaos: An Interdisciplinary Journal of Nonlinear Science, 1999
Orbital stability of limit cycles is the result of the competing local tendencies of perturbations from the cycle to decay (during phases of local stability) and to grow (during phases of local instability), averaged over a cycle. We examine this coexistence of attractive and repulsive phases on limit cycles, including the local rates of expansion and ...

On the stability of double homoclinic and heteroclinic cycles

Nonlinear Analysis: Theory, Methods & Applications, 2003
The authors study the stability of a polycycle \(L\) with two regular sides, \(L_1\) and \(L_2,\) and two hyperbolic corners, \(s_1\) and \(s_2\) (which eventually may coincide), of a \(C^5\) planar vector field \(X.\) It is not restrictive to assume that it is oriented clockwise and that the omega limit set of the side \(L_1\) is \(s_2.\) Denote by \(\

Stability and Positivity of Cycles

2019
We use Bridgeland stability conditions to study restrictions of stable vector bundles on projective varieties. We also study positivity properties of classical moduli spaces of sheaves, particularly Hilbert schemes of points. Positivity of cycles on blow-ups of Grassmannians is discussed in the second half.

Nonconnected heterodimensional cycles: bifurcation and stability

Nonlinearity, 1992
Consider one-parameter families of diffeomorphisms of a smooth closed \(n\)-manifold for \(n\geq 3\). Two hyperbolic periodic points \(P_ t\), \(Q_ t\) are followed through the parameter interval where the 2-dimensional unstable manifold \(W^ u(Q_ t)\) intersects the \((n-1)\)-dimensional stable manifold \(W^ s(P_ t)\). If \(W^ s(Q_ b)\cap W^ u(P_ b)\)
