Advanced Science, EarlyView.At alkaline conditions (pH = 13), for FePPc and Pz‐FeTPr at low potential (less than 0.5 V), the ORR mechanism is the *O2 mechanism (O2→∗O2→∗OOH→∗O→∗OH→H2O${{\rm{O}}_2} \to ^*{O_2} \to ^*OOH \to ^*O \to ^*OH \to {H_2}O$), Fe is the active site; for Pz‐FeTPr at high potential (larger than 0.5 V), the Fe site is covered by O2−$O_2^ - $, the nearby C site

Journal of Functional Analysis, 2005 AbstractIn this paper, the Saddle-point theorems are generalized to a new version by showing that there exists a “sign-changing” saddle point besides zero. The abstract result is applied to the semilinear elliptic boundary value problem-Δu=f(x,u)inΩ,u=0on∂Ωand the Schrödinger equation -Δu+Vλ(x)u=f(x,u),x∈RN,u(x)→0as|x|→∞,where Ω⊂RN is a bounded domain ...

Resistance Drift of Phase Change Materials Beyond the Power Law
Advanced Electronic Materials, EarlyView.The timedependent resistance of phase change materials is important for their application as electronic memory. Here, resistance measurements of melt‐quenched germanium telluride from nanoseconds to minutes are presented. By going far beyond the usually considered measurement regime, deviations from the ubiquitous power law behavior are observed, that ...

Advanced Electronic Materials, EarlyView.Atomistic analysis of ruthenium (Ru) and oxygen vacancy (OV) diffusion in Ta₂O₅‐based memristors is performed. DFT calculations demonstrate interstitial Ru in Ta₂O₅ has lower diffusion barriers and formation energies than OVs, enhancing mobility and stability.

Advanced Energy Materials, EarlyView.The novel kinetic Monte Carlo model presented here incorporates spatially‐ and time‐dependent electrical potential, which enables the precise study of the solid electrolyte interphase formation in Na‐ion batteries. The effects of electrolyte composition and charging conditions on the growth and behavior of the solid electrolyte interphase during the ...

Angewandte Chemie, EarlyView.A series of unusual low HOMO‐LUMO gap polyacetylenes bearing ring‐fused tellurophene and vinyl side chains were prepared by combining metallacycle transfer (Hf/p‐block element exchange) with ring‐opening metathesis polymerization (ROMP) into a single modular and efficient protocol.

Morse Thoery of Saddle Point Reduction with Applications
AxiomsIn this paper, we demonstrate that when saddle point reduction is applicable, there is a clear relationship between the Morse index and the critical groups before and after the reduction.

Angewandte Chemie, EarlyView.Phase transition from melt to most complex liquid crystal (LC) phases is weak 1st order but is preceded by a large heat capacity maximum. In addition, a chiral liquid forms through another transition before that to the LC, despite the compounds being achiral.
