Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.

Propagation of Pressure Perturbations in a Porous Medium Saturated with Bubbly Liquid [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2015 Wave processes in a porous medium saturated with bubbly liquid are numerically investigated. The nonlinearity of gas constitutive and Rayleigh–Lamb equations for bubble oscillations is taken into account.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation
Advanced Functional Materials, EarlyView.This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Bingham Fluid Flow through a Tapered Tube with Permeable Wall
Journal of Applied Fluid Mechanics, 2013 Bingham fluid flow through a tapered tube with permeable wall studied. The flow takes place due to pressure gradient, and the porous medium is homogeneous with permeability k. The flow surrounded by the porous medium is governed by the Bingham model, and
