Mechanical and Thermal Characteristics of Films from Glycerol Mixed Emulsified Carnauba Wax/Polyvinyl Alcohol.

Poly(vinyl alcohol) (PVA)-based films have drawn significant attention owing to their potential applications in various industries. The application of wax to PVA films enhanced their resistance to dissolution and water infiltration. Nevertheless, waxed PVA films often exhibit inadequate mechanical properties owing to crack formation.

Trends in Biological Ammonia Production.

Food production heavily depends on ammonia-containing fertilizers to improve crop yield and profitability. However, ammonia production is challenged by huge energy demands and the release of ~2% of global CO. To mitigate this challenge, many research efforts have been made to develop bioprocessing technologies to make biological ammonia.

Understanding gaseous reduction in swine manure resulting from nanoparticle treatments under anaerobic storage conditions.

Manure is an impending source of carbon (C), sulfur (S) and water (HO). Consequently, microbial populations utilize these constituents to produce methane (CH), carbon dioxide (CO), greenhouse gases (GHGs), and hydrogen sulfide (HS). Application of nanoparticles (NPs) to stored manure is an emerging GHG mitigation technique.

Nanoparticles in mitigating gaseous emissions from liquid dairy manure stored under anaerobic condition.

A number of mitigation techniques exist to reduce the emissions of pollutant gases and greenhouse gases (GHGs) from anaerobic storage of livestock manure. Nanoparticle (NP) application is a promising mitigating treatment option for pollutant gases, but limited research is available on the mode of NP application and their effectiveness in gaseous emission reduction. In this study, zinc silica nanogel (ZnSNL), copper silica nanogel (CuSNL), and N-acetyl cysteine (NACL) coated zinc oxide quantum dot (Qdot) NPs were compared to a control lacking NPs.

In vitro evaluation of nano zinc oxide (nZnO) on mitigation of gaseous emissions.

Background: Enteric methane (CH) accounts for about 70% of total CH emissions from the ruminant animals. Researchers are exploring ways to mitigate enteric CH emissions from ruminants. Recently, nano zinc oxide (nZnO) has shown potential in reducing CH and hydrogen sulfide (HS) production from the liquid manure under anaerobic storage conditions.
