Journal of Polymer Science, EarlyView.Compatibilization markedly improves the top‐load compression performance and structural integrity of HDPE/PP blow‐molded bottles. Neat HDPE, PP, and HDPE/PP bottles exhibit premature neck cracking at relatively low strains, whereas the compatibilized HDPE/PP/C blend sustains substantially higher loads and greater deformation without cracking ...

Thermodynamics-like Formalism for Immiscible and Incompressible Two-Phase Flow in Porous Media
EntropyIt is possible to formulate an immiscible and incompressible two-phase flow in porous media in a mathematical framework resembling thermodynamics based on the Jaynes generalization of statistical mechanics. We review this approach and discuss the meaning

Digital acoustofluidics enables contactless and programmable liquid handling
Nature Communications, 2018 Contamination is an obstacle to the functioning of microfluidic devices. Here the authors exploit acoustic streaming to manipulate droplets which float on a layer of immiscible oil. This prevents contamination and enables rewritability by which different

ChemEngineering, 2019 We investigate the interaction of two immiscible fluids in a head-on device geometry, where both fluids are streaming opposite to each other. The simulations are based on the two-dimensional (2D) lattice Boltzmann method (LBM) using the Rothman and ...

Vibrational Exfoliation of 2D Materials
Small, EarlyView.Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Small, EarlyView.This study presents a new category of polymer adhesives applicable to poly(p‐phenylene sulfide) (PPS) and metal substrates, without requiring any physical/chemical surface treatment. The key concept lies in the amphiphilic block copolymer structures, which comprise exceptionally miscible PPS derivative segments and metal‐adhesive catechol segments ...

Rheology of High-Capillary Number Two-Phase Flow in Porous Media
Frontiers in Physics, 2019 Flow of immiscible fluids in porous media at high capillary numbers may be characterized by an effective viscosity. We demonstrate that the effective viscosity is well-described by the Lichtenecker-Rother equation.

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.

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
