    Atomic layer deposition of nanofilms on porous polymer substrates: Strategies for success Editor’s Pick

    Brian C Welch, Jeanne Casetta, Rajesh Pathak, Jeffrey W Elam, Céline Pochat-Bohatier, Philippe Miele, Tamar Segal-Peretz
    Abstract

    Atomic layer deposition (ALD) is a versatile technique for engineering the surfaces of porous polymers, imbuing the flexible, high-surface-area substrates with inorganic and hybrid material properties. Previously reported enhancements include fouling resistance, electrical conductance, thermal stability, photocatalytic activity, hydrophilicity, and oleophilicity. However

    Ion uptake and pairing in membranes: The pore model

    Abstract

    Ion uptake plays a critical role in membrane separations used for water purification and electro-membrane processes. Although models of ion uptake usually consider free dissociated ions, ion-pairing was suggested to play an important role as well and but its understanding in the context of membrane transport is still insufficient. The paper systematically develops the

    Using wetting and ultrasonic waves to extract oil from oil/water mixtures

    Yifan Li, Jesus M Marcos, Mark Fasano, Javier Diez, Linda Cummings, Lou Kondic, Ofer Manor
    Abstract

    Oil and water phases placed on top of a solid surface respond differently to a MHz-level surface acoustic wave (SAW) propagating in the solid due to their different surface tensions and the corresponding capillary stresses. We observe that, under SAW excitation, oil films are extracted continuously from sessile drops of silicone-oil/water/surfactant mixtures. The

    Chemical Tomography of Cancer Organoids and Cyto-Proteo-Genomic Development Stages Through Chemical Communication Signals

    Arnab Maity, Vivian Darsa Maidantchik, Keren Weidenfeld, Sarit Larisch, Dalit Barkan, Hossam Haick
    Abstract

    Organoids mimic human organ function, offering insights into development and disease. However, non-destructive, real-time monitoring is lacking, as traditional methods are often costly, destructive, and low-throughput. In this article, a non-destructive chemical tomographic strategy is presented for decoding cyto-proteo-genomics of organoid using volatile signaling

    Pressure-dependent kinetic analysis of the N2H3 potential energy surface

    Abstract

    The pressure-dependent reactions on the N2H3 potential energy surface (PES) have been investigated using CCSD(T)-F12/aug-cc-pVTZ-F12//B2PLYP-D3/aug-cc-pVTZ. This study expands the N2H3 PES beyond the previous literature by incorporating a newly identified isomer, NH3N, along with additional bimolecular reaction channels associated with this isomer, namely NNH + H2 and

    Abstract

    Cardiovascular diseases, which cause ≈10 million deaths annually, underscored the importance of effective blood pressure (BP) monitoring. Traditional devices, however, faced limitations that hindered the adoption of continuous monitoring technologies. Flexible triboelectric nanogenerator (TENG) sensors, known for their rapid response, high sensitivity, and cost-effectiveness

    Mechanical-Transport Coupling in Membranes: Generalized Model and Non-Equivalence of Molecular Simulations and Experiments

    Abstract

    The solution-diffusion (SD) model has faithfully served membrane research for decades, however, recently reported discrepancies between molecular dynamics and experiments reignited a debate on its validity. This study places on a solid foundation the picture of SD as mechanical-transport coupling put forward recently. The full set of coupled relations is rigorously

    Kinetics of Macroion Adsorption on Silica: Complementary Theoretical and Experimental Investigations for Poly-l-arginine

    Maria Morga, Dominik Kosior, Małgorzata Nattich-Rak, Izabella Leszczyńska, Piotr Batys, Zbigniew Adamczyk, Alexander Leshansky
    Abstract

    A comprehensive approach enabling a quantitative interpretation of poly-l-arginine (PARG) adsorption kinetics at solid/electrolyte interfaces was developed. The first step involved all-atom molecular dynamics (MD) modeling of physicochemical characteristics yielding PARG molecule conformations, its contour length, and the cross-section area. It was also shown that PARG

    Intensification of Palladium Membrane Separators and Reactors by Applied Electric Field: A Multi-Scale Modeling Study

    Abstract

    Pd-based membranes have a great potential for efficient production of pure hydrogen, enabling effective small-scale hydrogen production. Co-adsorption of gas phase species, mainly CO, is known to significantly limit the hydrogen flux through these expensive membranes. In this study, we employ a multi-scale modeling approach to investigate the impact of an applied electric

    Identifying and Quantifying Loss Sources in Anion-Exchange Membrane Water Electrolyzers

    Abstract

    Anion-exchange membrane (AEM) water electrolyzers (AEMWEs) have gained significant attention for their ability to utilize precious-metal-free catalysts and environmentally friendly fluorine-free hydrocarbon polymeric membranes. In this study, we identify and quantify the sources of performance losses in operando AEMWEs using an innovative approach based on electrochemical
