New Exact Solutions for the (2+1)-Dimensional Broer-Kaup-Kupershmidt Equations
Abstract and Applied Analysis, 2010 We investigate the (2+1)-dimensional Broer-Kaup-Kupershmidt equations. Some explicit expressions of solutions for the equations are obtained by using the bifurcation method and qualitative theory of dynamical systems.

On Blow-up Sets for the Parabolic Equation dt ∂tβ(u) = ⊿u+f(u) in a Ball [PDF]
, 1991 Radially symmetric solutions of nonlinear degenerate parabolic equations are considered in a ball, under some blow-up conditions on β(ξ), f(ξ) and the initial date.

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures
Advanced Functional Materials, EarlyView.To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.

Blow up of solutions to semilinear wave equations
Electronic Journal of Differential Equations, 2003 This work shows the absence of global solutions to the equation $$ u_{tt} = Delta u + p^{-k}|u|^m, $$ in the Minkowski space $mathbb{M}_0=mathbb{R}imesmathbb{R}^N$, where $ m > 1$, $(N-1)m < N+1$, and $p $ is a conformal factor approaching 0 at infinity.

Periodic Wave Solutions and Their Limits for the Generalized KP-BBM Equation
Journal of Applied Mathematics, 2012 We use the bifurcation method of dynamical systems to study the periodic wave solutions and their limits for the generalized KP-BBM equation. A number of explicit periodic wave solutions are obtained.

Acetoacetates Derived From Vegetable Oils: A Platform for Tailor‐Made Vinylogous Urethane Foams
Advanced Functional Materials, EarlyView.A renewable vegetable oil is converted into acetoacetate‐functionalized precursors for the preparation of catalyst‐free vinylogous urethane foams. Room‐temperature foaming with n‐pentane generates lightweight cellular materials, while the choice of amine enables control over foam structure and mechanical properties.

Advanced Materials, EarlyView.A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...
