Rational Design of Photoanodes in Portable Devices to Enhance H2O2 Production for Microenvironment Control

open access: yesCarbon Energy, EarlyView.
Herein, a rational photoanode design enhances H2O2 production via H2O oxidation in a PEC system, with Mo‐doped BiVO4 films and planar Co‐py co‐catalysts achieving optimal performance at 8.4 μmol·h−1·cm−2. Mo6+ doping tailors Fermi level alignment while Co‐py stabilizes *OH intermediates and promotes H2O2 desorption, as confirmed by operando analyses ...

A system of nonlinear degenerate parabolic equations

open access: yes, 1986
Existence, uniqueness, regularity and asymptotic behavior results are proved for the coupled system of degenerate parabolic equations \[ u^ i_ t(t,x)=k_ iu^ i(t,x)K(P(t,x))P_{xx}(t,x), \] \[ P(t,x)=\sum^{N}_{1}u^ i(t,x),\quad u^ i(t,0)=u^ i(t,1)=0,\quad u^ i(0,x)=u^ i_ 0(x) \] with \(i=1,2,...,N\), and (t,x)\(\in [0,T]\times [0,1]\). K is assumed to be

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

A priori estimates and large population limits for some nonsymmetric Nash systems with semimonotonicity

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We address the problem of regularity of solutions ui(t,x1,…,xN)$u^i(t, x^1, \ldots, x^N)$ to a family of semilinear parabolic systems of N$N$ equations, which describe closed‐loop equilibria of some N$N$‐player differential games with Lagrangian having quadratic behaviour in the velocity variable, running costs fi(x)$f^i(x)$ and final costs gi(
