    Base-free transfer hydrogenation of aldehydes and ketones catalyzed by imidazolin-2-iminato actinide complexes

    Hemanta Deka, Natalia Fridman, Marvin Koneczny, Matthias Tamm, Moris S Eisen
    Abstract

    A series of thorium(IV) (3, 4, 9, 10) and uranium(IV) (5, 6, 11, 12) complexes decorated with the unsymmetrical imidazolin-2-iminato ligands L1 and L2 were synthesized and found to be effective as catalysts in the transfer hydrogenation of aldehydes and ketones with 2-propanol to form the corresponding alcohols with good yields, representing a rare example for actinides

    Evaluating life cycle environmental impacts of coal fly ash utilization in embankment versus sand and landfilling

    Abstract

    Coal fly ash (CFA) disposal is controversial because constituents of potential concern such as heavy metals in the ash can be released to the ground and reach aquifers, which poses risks to communities and the environment. Whereas thoughtful utilization of CFA may result in economic and environmental benefits. Geotechnical use of CFA as fill material in embankments

    Coherent Nanointerface between Light-harvesting and Catalytic Transition Metal Sulfides for Efficient Photochemical Conversion

    Yuexing Chen, Ming Ma, Jun Hu, Zhong Chen, Peng Jiang, Lilac Amirav, Shihe Yang, Zheng Xing
    Abstract

    Creating atomically coherent interfaces can sharpen the physiochemical properties and functionalities of nanomaterials for efficient energy conversion via manipulating the charge flow. While coherent interfaces can be built between transition metal dichalcogenides with structural similarities and weak interlayer van der Waals interactions, it remains challenging to

    Energy storage for mitigating grid congestion caused by electric vehicles: A techno-economic analysis using a computationally efficient graph-based methodology

    Aviad Navon, Ran Nitskansky, Eshel Lipman, Juri Belikov, Nurit Gal, Ariel Orda, Yoash Levron
    Abstract

    This paper studies the impact of electric vehicle charging on congestion in low-voltage networks and the economic feasibility of energy storage as an alternative to conventional network upgrades. To this end, we propose a computationally efficient graph-based methodology and employ it on a GIS data set of over 6,500 low-voltage networks. We provide insights regarding

    Electronic Coupling and Electrocatalysis in Redox Active Fused Iron Corroles

    Amir Mizrahi, Susovan Bhowmik, Arun K Manna, Woormileela Sinha, Amit Kumar, Magal Saphier, Atif Mahammed, Moumita Patra, Natalia Fridman, Israel Zilbermann, Leeor Kronik, Zeev Gross
    Abstract

    Conjugated arrays composed of corrole macrocycles are increasingly more common, but their chemistry still lags behind that of their porphyrin counterparts. Here, we report on the insertion of iron(III) into a β,β-fused corrole dimer and on the electronic effects that this redox active metal center has on the already rich coordination chemistry of [H3tpfc] COT, where

    PF-FEDG: An open-source data generator for frequency disturbance event detection with deep-learning reference classifiers

    Zhenglong Sun, Ram Machlev, Chao Jiang, Qianchao Wang, Michael Perl, Juri Belikov, Yoash Levron
    Abstract

    Accurate and fast classification of FDEs is crucial to power systems situation awareness and stability control. However, various database used in recent studies makes it hard to directly compare different classification methods. To relieve the lack of a standardized database that can be used as a benchmark, this work proposes an open-source package which generates

    Self-assembled fatty acid crystalline coatings display superhydrophobic antimicrobial properties

    Abstract

    Superhydrophobicity is a well-known wetting phenomenon found in numerous plants and insects. It is achieved by the combination of the surface's chemical properties and its surface roughness. Inspired by nature, numerous synthetic superhydrophobic surfaces have been developed for various applications. Designated surface coating is one of the fabrication routes to achieve

    A workflow for automatic generation and efficient refinement of individual pressure-dependent networks

    Matthew S Johnson, Alon Grinberg Dana, William H Green
    Abstract

    Manual chemical kinetic model construction often requires modelists to at least implicitly guess all possible decay pathways and their relative fluxes for all important species. We present a workflow and associated tool for automatic generation and refinement of pressure-dependent networks (multiwell potential energy surfaces) that should enable modelists to efficiently

    Nano Schottky?

    Lilac Amirav, Maria Wächtler
    Abstract

    The existence of a reduced Schottky barrier at the nanoscale junction between semiconductor and metal domains has yet to be acknowledged among the photocatalysis community, despite its critical role in dictating the quality and functionality of the hybrid photocatalytic system.

    Self-Enclosed Bio-Photoelectrochemical Cell in Succulent Plants

    Abstract

    Harvesting an electrical current from biological photosynthetic systems (live cells or isolated complexes) is typically achieved by immersion of the system into an electrolyte solution. In this study, we show that the aqueous solution found in the tissues of succulent plants can be used directly as a natural bio-photo electrochemical cell. Here, the thick water-preserving
