    Design Methodology and Concept Demonstration of Preassembled Additively Manufactured Turbomachinery Systems: Case Study of Turbocharger Based Medical Ventilators

    Abstract

    Abstract. Present research focuses on analyzing feasibility of manufacturing complex turbomachinery geometries in a preassembled manner through an uninterrupted additive manufacturing process, absent of internal support structures or post-processing. In the context of the present COVID19 pandemic, the concept is illustrated by printable turbine-driven blower-type medical

    Insights into the chemistry of vapor phase infiltration for imaging non-fullerene acceptors

    Abstract

    Vapor phase infiltration (VPI) processes offer a unique method to form hybrid materials by growing inorganic species inside polymer matrices from gaseous precursors. The VPI process follows three main stages: sorption of the gas phase precursors to the polymer matrix, their diffusion and entrapment in the matrix, and the chemical reaction. The distinct entrapment

    Abstract

    Mixed ionic–electronic conductive polymers are gaining high momentum for several electronic and bioelectronic applications. These polymers are composed of a synthetic conjugated polymer for electronic conduction and a synthetic ionomer for the ionic one. To make these materials more environmentally sustainable, much effort is being put in replacing synthetic polymers

    Agglomeration in Composite Propellants Containing Different Nano-Aluminum Powders

    Abstract

    In order to improve nano-aluminized solid propellant properties and performance, different materials are being investigated for coating nano-aluminum particles. Two of the powders which are considered are V-ALEX, a fluoropolymer (Viton) coated nano-aluminum, and L-ALEX, a stearic acid coated nano-aluminum. It is believed that a thin layer of coating should protect the

    A Review on Design Considerations in Polymer and Polymer Composite Solid-State Electrolytes for Solid Li Batteries

    Abstract

    The current all-solid-state battery (ASSB) technology must stride through meticulous research work to reap the much-sought benefits of high energy density, stable cycling life and economical fabrication of ASSBs for large scale applications. Among all the prevailing scientific challenges, low room temperature ionic conductivity and interfacial impedance are the major

    Abstract

    Agricultural development, extensive industrialization, and rapid growth of the global population have inadvertently been accompanied by environmental pollution. Water pollution is exacerbated by the decreasing ability of traditional treatment methods to comply with tightening environmental standards. This review provides a comprehensive description of the principles

    Improving Alkaline Hydrogen Oxidation Activity of Palladium through Interactions with Transition-Metal Oxides

    Maria V Pagliaro, Cuilian Wen, Baisheng Sa, Baoyu Liu, Marco Bellini, Francesco Bartoli, Sanjubala Sahoo, Ramesh Kumar Singh, S Pamir Alpay, Hamish A Miller, Dario R Dekel
    Abstract

    Anion-exchange membrane fuel cells (AEMFCs) are a promising electrochemical power generation technology that will most likely find applications in stationary power supply and mobile applications such as electric vehicles in the future. One of the main technological challenges with AEMFCs is developing catalysts with improved activities to reduce the current overpotential

    A desert green alga that thrives at extreme high-light intensities using a unique photoin-hibition protection mechanism

    Guy Levin, Michael Yasmin, Marc C Simanowitz, Ayala Meir, Yaakov Tadmor, Joseph Hirschberg, Noam Adir, Gadi Schuster
    Abstract

    While light is the driving force of photosynthesis, excessive light can be harmful. Photoinhibi-tion, or light-induced photo-damage, is one of the key processes limiting photosynthesis. When the absorbed light exceeds the amount that can be dissipated by photosynthetic elec-tron flow and other processes, damaging radicals are formed that mostly inactivate photosys-tem

    Self-Assembled Fatty Acid Crystalline Coatings Display Non-Toxic Superhydrophobic Antimicrobial Properties

    Abstract

    Superhydrophobcity is a well-known wetting phenomenon found in numerous plants and insects. It is achieved by the combination of the surfaces 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

    Abstract

    This study focuses on H2-O2 operando AEMFC performance based on several platinum group metal (PGM) and PGM-free catalysts. Specifically, we evaluate the AEMFC performance of commercial PtRu/C, as-synthesized PtRu/C, and Pd-CeO2/C catalysts as anodes and commercial Pt/C and as-synthesized N-doped carbon catalysts as cathodes. The evolution of cell performance with varying
