Small, EarlyView.Surface‐enhanced infrared absorption (SEIRA) and Raman scattering (SERS) are complementary, highly sensitive molecular detection methods. A reusable metamaterial substrate capable of combined SEIRA and SERS is used here for real‐time sensing, tracking interfacial dynamics in an electrochemical reaction and detecting symmetry‐breaking behavior at the ...

Effective rheology of immiscible two-phase flow in porous media
, 2012 We demonstrate through numerical simulations and a mean-field calculation that immiscible two-phase flow in a porous medium behaves effectively as a Bingham viscoplastic fluid.

Three‐Dimensional Piezoelectric Fibrous Constructs for Muscle Regeneration
Small, EarlyView.This study fabricates 3D piezoelectric PHBV scaffolds to enhance muscle regeneration by systematically tuning electrospinning parameters. Introducing porosity yields a 25‐fold enhancement in the effective piezoelectric coefficient (d33). A highly effective d33 signal, activated by cellular tension and fiber deformation, significantly improves myogenic ...

Fast and Selective Photochemical Doping of Spiro‐OMeTAD
Small Methods, EarlyView.Sixty seconds of UV light converts spiro‐OMeTAD into its clean +1/+2 oxidized states while >98% of lithium is extracted into an aqueous phase by 12‐crown‐4. Proton‐tunable hydroxyl‐radical chemistry generates oxidants whose reduction potentials bracket the spiro2+/spiro3+ couple, providing thermodynamic oxidation‐state selectivity, as quantified by DFT.

Effect of Implementing Three-Phase Flow Characteristics and Capillary Pressure in Simulation of Immiscible WAG [PDF]
, 2008 The effect of including a three-phase representation of the flow parameters and capillary pressure has been investigated using a black oil simulator. The simulation approaches include the complexity of three-phase flow, relative permeability hysteresis ...

steel research international, EarlyView.Bubble transport in continuous casting is controlled by the interaction of bubble size, flow dynamics, and operating conditions. Critical regions governing bubble escape and entrapment are identified, revealing the mechanisms responsible for defect formation and providing practical guidance for process optimization. Argon injection is often used in the

The Chemical Record, EarlyView.Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...
