Mechanical properties of polymer biocomposites are influenced by the interaction between matrix and filler surface. In this work, composites based on poly(butylene-adipate-terephthalate) (PBAT) filled with micrometric particles zein-TiO2 complex (ZTC) were realized via solvent casting technique at different concentrations, equal to 0, 5, 10, 20 wt%. After pelletization, resulting materials inje...

CO2 capture using alkali metal salt (AMS)-promoted MgO-based sorbents at intermediate temperatures (300–500 °C) has gained increased interest recently. The prospects of such materials for were assessed in this work. We investigated the most reactive that have been reported literature (i.e., MgO promoted with a combination various AMS (including NaNO3, LiNO3, K2CO3, and Na2CO3)), examined how pa...

Ferrochrome (FeCr) is the main source of virgin chromium (Cr) units used in modern-day containing alloys. The vast majority produced Cr during production stainless steel, which owes its corrosion resistance mainly to presence Cr. In turn, steel from Cr-containing scrap metal and FeCr, a relatively crude alloy between iron (Fe) FeCr an energy material-intensive process, wide variety by-products,...

The metal–organic frameworks CuBTC and UiO-66 were pressed at 1000 and 10,000 psi as a first step to engineering particles for use in toxic chemical removal applications. Materials characterization was conducted on each material using powder X-ray diffraction, attenuated total reflectance – Fourier transform infrared spectroscopy, and nitrogen porosimetry. Neither material showed signs of struc...

Torrefaction of biomass can be described as a mild form of pyrolysis at temperatures typically ranging between 200 and 300°C in an inert and reduced environment. Common biomass reactions during torrefaction include devolatilization, depolymerization, and carbonization of hemicellulose, lignin, and cellulose. The torrefaction process produces a brown to black uniform solid product, as well as co...

Introduction and Methods Cohesive sediments in marine and coastal environments are responsible for degrading water quality, influencing the cycling and availability of particle bound contaminants, and infilling navigable waterways. In spite of their significance to coastal environments, there are still major gaps in our understanding of many of the fundamental processes governing cohesive sedim...
