Summary: This study demonstrates that the microporosity of three-dimensionally ordered micromesoporous carbon (3DOmm) can be increased by physical activation, leading to improved CO2 capture performance. The activated 3DOmm carbon exhibits a highly porous amorphous structure with increased micropore and mesopore volumes and a higher specific surface area. Furthermore, the activated 3DOmm carbon shows excellent CO2 adsorption performance over a wide pressure range, with fast kinetics and high selectivity for CO2 over N2.

Summary: This study examines the adsorption kinetics of activated carbon (AC) adsorbent materials produced from a by-product of African palm processing. The textural characteristics of the adsorbent solids were determined through N-2 physisorption, revealing BET areas between 721 and 1334 m(2)g(-1) and micropore volumes between 0.33 and 0.55 cm(3)g(-1). FTIR was used for chemical characterization, and CO2 adsorption was measured, showing values between 175 and 274 mg·g(-1). The kinetic study suggests that the intraparticle diffusion model best describes the physisorption process.

Summary: The study focused on the co-pyrolysis of single-use face masks and food waste for energy and resource valorization. Pyrolysis of the face masks produced fuel-range chemicals and primarily non-condensable hydrocarbons. Adding food waste led to char formation without affecting the properties of the char, increasing H2 production and decreasing hydrocarbon yields during co-feeding pyrolysis.

Summary: This research investigates the adsorption of organic and inorganic pollutants on carbonaceous adsorbents prepared from expired or broken food products. The activation process was conducted using potassium carbonate and orthophosphoric acid as activating agents. The activated carbons were characterized and their suitability as adsorbents for methylene blue and iodine removal from aqueous solutions was evaluated. The materials activated with H3PO4 showed higher effectiveness in both pollutant adsorptions. The Langmuir isotherm model provided a better fit for the experimental adsorption data for all carbonaceous materials compared to the Freundlich model.

Summary: This study investigates the use of activated carbon materials derived from CO2 activation of Maize Cob Waste (MCW) as adsorbents for biogas upgrading. The carbon resulting from 3 hours of activation (MCW(PA)3 h) demonstrates better properties and selectivity towards CO2 compared to the one resulting from 2 hours of activation (MCW(PA)2 h). It shows higher CO2 uptake in the typical partial pressure range for biogas upgrading units and demonstrates good agreement between experimental results and the prediction using the axial dispersed plug-flow and Linear Driving Force (LDF) approximation for mass transfer modeling. This work lays the foundation for future modeling of a Pressure Swing Adsorption (PSA) cycle using MCW(PA)3 h as an adsorbent material and highlights the potential of this novel material for biogas upgrading processes.

Summary: Mould fungi pose serious threats to humans and animals, and may be the main cause of COVID-19-associated pulmonary aspergillosis. Common disinfection methods are not effective against fungi due to their high resistance. Photocatalysis has attracted attention for its antimicrobial properties, and titania photocatalysts have been used in various applications. This study presents the efficiency of photocatalytic methods in removing fungi and bacteria, which are risk factors for SARS-CoV-2 co-infection, and suggests that photocatalysis may help prevent the severity of the COVID-19 pandemic.

Summary: This study investigates the epoxidation of 1,5,9-cyclododecatriene (CDT) to 1,2-epoxy-5,9-cyclododecadiene (ECDD) using hydrogen peroxide on unmodified and silanized Ti-SBA-15 catalyst (Ti-SBA-15-TMS). Silanization improves the selectivity of the reaction by decreasing the rate of epoxidation but increasing the transformation of CDT and H2O2 to ECDD. The use of 90 wt% acetone as the solvent yields the highest selectivity.

Summary: Activated carbons with highly microporous structure were successfully prepared from avocado stones through NaOH activation and subsequent carbonization. The obtained activated carbons showed specific surface areas in the range of 817-1172 m²/g, total pore volumes of 0.538-0.691 cm³/g, and micropore volumes of 0.259-0.375 cm³/g. These activated carbons exhibited excellent CO2 adsorption capacity of 5.9 mmol/g at 0℃ and 1 bar, as well as selectivity over nitrogen for flue gas simulation. The novelty of this work lies in the production of high-performance activated carbons from avocado stones using NaOH activation, which has not been reported before.

Summary: Carbon-supported nickel catalysts with different Ni content were tested in the oxidation of alpha-pinene under solvent-free conditions. The catalysts were prepared using activated carbon from spent coffee grounds and nickel compounds, and characterized using various instrumental techniques. The catalytic tests revealed that the catalysts with 5 wt% and 1 wt% of Ni content showed the highest activity in the oxidation reaction, producing alpha-pinene oxide, verbenol, and verbenone. The hydrothermal method of catalyst preparation was found to be more advantageous, likely due to the higher selectivity of epoxide compound in the pores.

Summary: Activated carbons with different physicochemical characteristics were studied to determine their interactions with hydrocarbons. The enthalpy of immersion was determined to evaluate the influence of adsorbents and adsorbates, as well as the addition of another adsorbate. The results showed that the interaction increased with thermal treatment and decreased with chemical modification, both in pure solvents and mixtures. The CO2 adsorption of activated carbons ranged from 3.43 to 3.79 mmol g(-1).

Summary: A library of furan-based block copolymers was synthesized via a two-step polycondensation reaction using Candida antarctica lipase B as biocatalyst. The resulting copolymers were analyzed using NMR, FTIR, and GPC. XRD, DHM, and DSC were used to study the crystallization behavior and thermal properties, while OTR was measured to verify the oxygen permeability of the furan-based copolyesters. The chain length of α,ω-aliphatic linear diols used in the synthesis had a significant effect on the material properties.
