Advanced Energy Materials, EarlyView.An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Minimum and comparison principles for semilinear nonlocal reaction–diffusion equations
Boundary Value ProblemsWe consider second-order linear parabolic partial differential inequalities that include nonlocal zeroth-order quantities. For these, we establish minimum principles that highlight the interplay between the regularity of their coefficients, the growth ...

Abstract quasilinear parabolic equations with variable domains
Differential and Integral Equations, 1991 The Cauchy problem for the equation \(u'=A(u)u+f(u)\) is studied in a Banach space \(X\). The main supposition is the existence of a constant interpolation space between \(D(A)\) and \(X\), allowing the reduction to the case with constant domain.

Advanced Energy Materials, EarlyView.Flexible n‐type Bi2Te3 thin films require improved room‐temperature figure of merit (ZT) and mechanical stability. We show that synergistic Bi–Te antisite tuning and crystalline–amorphous hybridization optimizes carrier concentration, mobility, and phonon scattering.

In Situ Contact Angle Measurement for Autonomous Spin Coating in Self‐Driving Labs
Advanced Intelligent Discovery, EarlyView.A vision‐based add‐on transforms commercial spin coaters into autonomous modules of Self‐Driving Labs. Combining a width‐scaled U‐Net with classical geometric analysis, the system simultaneously measures contact angles and estimates substrate pose using a single camera.

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype
Advanced Intelligent Systems, EarlyView.A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Solutions in $L^p$ of abstract parabolic equations in Hilbert spaces
Kyoto Journal of Mathematics, 1993 Let \(H\) be a complex Hilbert space. The author considers the linear parabolic Cauchy problem \((C): u'(t)+ A(t)u(t)= f(t)\), \(t\in (0,T)\), \(u(0)= u_ 0\), where the operators \(-A(t)\) are infinitesimal generators of analytic semigroups in \(H\), with domains which may vary with \(t\).

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...
