Grafted poly (methacrylic acid-g-ethylene glycol) [P(MAA-g-EG)] copolymers were synthesized and their pH sensitivity was investigated. P(MAA-g-EG) membranes showed pH sensitivity due to complex formation and dissociation. Uncomplexed equilibrium swelling ratios were 40 to 90 times higher than those of the complexed states and varied according to copolymer composition and poly(ethylene glycol) (...

Ethylene has long been considered the key regulator of ripening in climacteric fruit. Recent evidence showed that auxin also plays an important role during fruit ripening, but the nature of the interaction between the two hormones has remained unclear. To understand the differences in ethylene- and auxin-related behaviours that might reveal how the two hormones interact, we compared two plum (P...

It was previously shown that when rabbit skeletal myofibrils are titrated with Mg2+ AMPPNP under conditions that result in the dissociation of cross-bridges from the thin filaments (i.e. 50% ethylene glycol, 0 degrees C), Ca2+-sensitive, biphasic binding is observed. These titrations have been repeated using myofibrils from which the troponin C has been selectively removed. The disappearance of...

The electrochemical CO and CO2 reduction reactions (CORR CO2RR) using copper catalysts renewable electricity hold promise as a carbon-neutral route to produce commodity chemicals fuels. However, the exact mechanisms structure sensitivity of Cu electrodes toward C2 products are still under debate. Herein, we investigate ethylene oxide (EOR) proxy late stages CORR ethylene, results compared those...

We report on a detailed model of an improved three mirror off-axis integrated cavity output spectroscopy (OA-ICOS) setup, which re-injects the light reflected by the optical cavity. The model simulates the impact of design parameters on instrument sensitivity and can be used for any off-axis configuration. We demonstrate the application of this model for the real-time detection of ethylene with...

Summary Esterases have emerged as important biocatalysts for enzyme-based polyester recycling of poly(ethylene terephthalate) (PET) to terephthalic acid (TPA) and ethylene glycol (EG). Here, we present process modeling, techno-economic, life-cycle, socioeconomic impact analyses an enzymatic PET depolymerization-based process, which compare with virgin TPA manufacturing. We predict that...

The process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. In this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. Effective separation techniques are required for separation of ethylene from unreacted ethane. Here a new adsorbent approach...
