“…In the biohybrids, TOCNF has a large amount of CCOH groups that facilitated Cu(II) adsorption, while NanoGO acted as nodes and joints, vastly enhancing the BBM membranes' exibility, mechanical strength, hydrolytic stability and water ux. 279 By constructing an ultrathin GO barrier layer on a cellulose nanober (CNF) membrane without the use of any crosslinker, high-ux water purication membranes may be made with a water ux rate of 18 124 L m −2 h −1 bar −1 and a dye inltration rate of 90 L m −2 h −1 bar −1 . 280,281 Meanwhile, 2methyltetrahydrofuran and glycerol derivatives were used to create asymmetric CA full-bio-based NF membranes via non-solvent induced phase separation.…”

“…Aerobic granular sludge (AGS) is an excellent alternative technology for treating both low-strength and high-strength wastewater. Up to now, various biological wastewater treatment processes have been implemented at full scale in the field and at lab scale for industrial and municipal wastewater treatment [1][2][3][4][5] . The activated sludge process (ASP) is considered one of the best conventional biological treatment approaches as it utilizes microorganisms to eliminate biodegradable contaminants found in different types of wastewaters.…”

Objective: The objective of the present work was to reduce the start-up time of aerobic granular sludge (AGS) formation using medium-strength sewage and to find the most effective anaerobic, aerobic (oxic), and anoxic (A/O/A) cyclic time distribution over the 6-hour cycle time for the removal of nutrients. Methods: A rectangular sequencing batch reactor (SBR) operated systematically in A/O/A cycle was designed for AGS formation. In order to achieve complete nutrient removal, the anoxic phase (5% of the total cycle duration) was introduced in the SBR cycle. Results: Growth in the biomass profile was observed after 20 days of operation, and complete granulation was achieved within 35 days of operational studies. Regular-shaped, compact granules with visible outlines and clear boundaries predominate inside the system, with an average particle size of 220.19 µm. The A/O/A system achieved average removal efficiencies of 70.02 ± 5.98%, 78.21 ± 18.66%, 60.62 ± 9.69%, and 53.49 ± 8.14% for COD, NH4+-N, TN, and PO43--P, respectively. The reasons for poor COD and PO43--P removal performance were the short anaerobic phase (25% of total cycle duration of 6 hours) and higher biomass concentration. However, the long aerobic phase (60% of total cycle duration of 6 hours) with the anoxic phase achieved outstanding (100%) NH4+-N removal efficiency after the system reached a steady state. SEM results inferred that rod-shaped bacteria, cocci, and filamentous fungi were the dominant microorganisms found within the cultivated granules. Conclusions: Sewage with a high COD loading rate accelerates AGS formation and development within an A/O/A cycle SBR reactor. The rapid granulation and simultaneous removal of organics and nutrients by the A/O/A mode SBR without any support materials provide an alternative for wastewater treatment.

Heterogeneous catalysis currently stands as a foundational area in materials synthesis and applied chemistry. In this context, emphasizing the significance of heterogeneous catalysis in expediting chemical reactions and controlling the formation of desired products using porous materials represents an intriguing approach in the current technological landscape. This work delves into the synthesis and design of a variety of porous materials, encompassing microporous, mesoporous and macroporous materials (e.g. carbonaceous materials, metal oxides, MOFs, zeolites and functionalized analogues), alongside their properties and characteristics pivotal in heterogeneous catalysis. among others, and their subsequent modification, underscoring the significance of tailoring porous materials for specific catalytic applications.
