Identification & Suggestion of Energy Efficient Alternative for Selected Building Materials

The total life cycle analysis can be divided as Operational Energy and Embodied Energy in case of the construction industry. The operational energy which is necessary for the whole life of the building starting from its genesis to ravage which includes energy required for heating and cooling are which is constructed already, processing of instruments, heat water and light rooms. The embodied energy can be explained as which enswathe and sustain the construction sites, for example, with a concrete panel, the energy need to manufacture cement, sand, aggregates, transport them to the site, mix them in a appropriate proportion, casing of them in a particular thickness. The energy required to ruin and recycle it can be taken in to account for best practice. Embodied energy is the addition of all the energy required to make a material from its manufacture to shipping. Embodied energy is comprises of the energy required for processing and manufacturing, transport, maintenance and demolition but it is very hard to calculate the energy required for the maintenance, demolition and transportation so because of this while calculating the embodied energy for the materials many researcher considered only processing and manufacturing energy

Development of a simple electroless method for depositing metallic Pt-Pd nanoparticles over wire gauge support for removal of hydrogen in a nuclear reactor

Electroless noble metal deposition on the conducting substrate is widely used to obtain the desired film or coating on the substrate of interest. Wire-gauge-based Pt/Pd/Pt-Pd (individually, sequentially, and simultaneously deposited) catalysts have been developed using formaldehyde and sodium formate as reducing agents. Various surface pretreatment methods like SnCl2 + PdCl2 seeding, oxalic acid etching, and HCl activation (etching) have been employed to obtain the desired noble metal coating. Minimum time duration was observed for simultaneously deposited catalysts using formaldehyde as a reducing agent. Prepared catalysts were characterized for noble metal deposition, coating kinetics, surface morphology, and binding energy. The catalyst was found to be active for H2 and O2 recombination reactions for hydrogen mitigation applications in nuclear reactors

Injecting Sustainability into Epoxy-Based Composite Materials by Using Bio-Binder from Hydrothermal Liquefaction Processing of Microalgae

We report a transformative epoxy system with a microalgae-derived bio-binder from hydrothermal liquefaction processing (HTL). The obtained bio-binder not only served as a curing agent for conventional epoxy resin (e.g., EPON 862), but also acted as a modifying agent to enhance the thermal and mechanical properties of the conventional epoxy resin. This game-changing epoxy/bio-binder system outperformed the conventional epoxy/hardener system in thermal stability and mechanical properties. Compared to the commercial EPON 862/EPIKURE W epoxy product, our epoxy/bio-binder system (35 wt.% bio-binder addition with respect to the epoxy) increased the temperature of 60% weight loss from 394 °C to 428 °C and the temperature of maximum decomposition rate from 382 °C to 413 °C, while the tensile, flexural, and impact performance of the cured epoxy improved in all cases by up to 64%. Our research could significantly impact the USD 38.2 billion global market of the epoxy-related industry by not only providing better thermal and mechanical performance of epoxy-based composite materials, but also simultaneously reducing the carbon footprint from the epoxy industry and relieving waste epoxy pollution
