Chemical depolymerization has been identified as a promising approach towards recycling of plastic waste. However, complete may be energy intensive with complications in purification. In this work, we have demonstrated upcycling mixed waste comprising mixture polyester, polyamide, and polyurethane through reprocessable vitrimer the depolymerized oligomers. Using poly(ethylene terephthalate) (PET) model polymer, first partial controlled depolymerization, using glycerol cleaving agent, to...
Digital information, when converted into a DNA sequence, provides dense, stable, energy-efficient, and sustainable data storage. The most stable method for encapsulating has been in an inorganic matrix of silica, iron oxide, or both, but are limited by low uptake complex recovery techniques. This study investigated rationally designed thermally responsive functionally graded (TRFG) hydrogel as simple cost-effective storing DNA. TRFG shows high uptake, long-term protection, reusability due to...
Effective electron mobilities are obtained by transport measurements on InAs nanowire field-effect transistors at temperatures ranging from 10 to 200 K. The mobility increases with below ∼30–50 K, and then decreases above 50 consistent other reports. magnitude temperature dependence of the observed can be explained Coulomb scattering ionized surface states typical densities. behaviour K is ascribed thermally activated increase in number scatterers, although nanoscale confinement also plays a...
Abstract Stimuli‐responsive semi‐interpenetrating polymer network (semi‐IPN) hydrogels form an important class of polymers for their tunable properties via molecular design. They are widely investigated a diverse range applications including drug delivery, sensors, actuators, and osmotic agents. However, in‐depth studies on some the critical design principles affecting diffusion/leaching linear from semi‐IPN lacking. Herein, first time, by preparing series model based thermally responsive...
Chemical recycling of poly(ethylene terephthalate) (PET) by depolymerization into monomers to recreate virgin-grade plastics is desirable; however, the energy-inefficient separation and purification steps needed obtain high-purity result in poor overall economic feasibility at present. Herein, we present a one-step integrated process for partial upcycling PET oligomers directly high-value products without any need solvent recovery purification. The key strategy our approach using...
Hydrogel composites with skin layer that allows fast and selective rejection of molecules possess high potential for numerous applications, including sample preconcentration point-of-use detection analysis. The stimuli-responsive hydrogels are particularly promising due to facile regenerability. However, poor adhesion the swelling-degree difference during continuous swelling/deswelling hydrogel hinders its further development. In this work, a polyamide strong was fabricated via gel-liquid...
In this study three configurations, viz. conventional MEA, interstage absorber, and absorber with two stripper configuration have been techno-economically evaluated for the optimized result by carrying out simulations using ASPEN PLUS. An economic model defined carbon capture 30 wt% MEA to reduce CO2 in flue gas 0.5 mol% of 550 MWe coal fired power plant resulted increase COE 20.6, 17.4, 15.6 percents respectively. The CO2-avoided cost configurations are 65.94, 64.05, 63.09 ($ /tonne avoided),

Abstract Systematic synthesis of interpenetrating polymer networks (IPN) from poly(chromium acrylate) (PCrA) and zinc acrylate (ZnA) using divinyl benzene (DVB) as crosslinker has been carried out. Swelling studies scanning electron microscopy (SEM) were performed to examine the extent crosslinking phase behavior IPN. The decreases with increase linear concentration its molecular weight, respectively. On other hand, it increases agent monomer II, IPN was found be thermally stable up 300 °C.
Perfluorooctanoic acid (PFOA) is a high-value chemical which has been widely used in semiconductor industries. Currently, there are lot of work focusing on the low concentration PFOA removal due to its potential toxicity, while recovery high from wastewater via adsorption could be more valuable. This reported novel pH-stimulated poly(dimethyl amino)ethyl methacrylate (PDMAEMA) microgel for selective recovery. The results showed that calculated maximum capacity PDMAEMA as 3300 mg g-1 presence...
