Thermodynamic Analysis of Low GWP Refrigerant Mixtures in a Refrigerator as Replacement to R-134A

Journal of Mechanical Engineering, 2019
Chlorofluorocarbons and hydro chlorofluorocarbons (HCFCs) are replaced by hydroflourocarbons (HFCs) which is not harmful to the ozone layer. However, few of HFCs have a relatively high global warming potential (GWP) and are subject to further examination

Modulating Covalent Organic Framework Nanochannel Microenvironments for Sustainable Hydrogen Peroxide Photosynthesis

Angewandte Chemie, EarlyView.
Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

GWP* of U.S. beef and dairy systems

, 2023
Global warming potential (GWP) is used to quantify the impact that greenhouse gases (GHG) have on the warming of the Earth's atmosphere relative to carbon dioxide (CO2). GWP* is a metric that is used to better quantify short-lived climate pollutants (SLCP) such as methane, hydrofluorocarbons, and sulfur dioxide. GWP* allows SLCP to be more consistently

Low-GWP refrigerants for medium and high-pressure applications [PDF]

International Journal of Refrigeration, 2017
The merits of an alternative refrigerant are established based on many attributes including environmental acceptance, chemical stability in the refrigeration system, low toxicity, flammability, efficiency and volumetric capacity. In an earlier work, these criteria were used to screen a comprehensive database to search for refrigerants with low global ...

Delineating groundwater potential recharge zones using remote sensing and GIS through the analytical hierarchy process (AHP) in northern Namibia’s landscapes

Geology, Ecology, and Landscapes
Water is a critical resource for human and ecological sustainability, particularly in semi-arid regions such as Namibia, where surface water is limited and evaporation rates are high.

Ecological life cycle analysis (LCA) on the example of materials used in warehouse buildings [PDF]

Archives of Civil Engineering
Construction cannot be called as an environment friendly process, hence many solutions are being developed to define the negative interactions of the buildings, determine the extent of environmental impact and find alternatives to improve design ...
