    Abstract Membrane bioreactors (MBRs) are frequently used to treat municipal wastewater, but membrane fouling is still the main weakness of this technology. Additionally, the low carbon-nitrogen (C/N) ratio influent has been shown to not only increase the membrane fouling, but also introduce challenges to meet the effluent discharge standard for nitrogen removal. Herein, the authors addressed the challenges by adding cost-effective biochar. The results suggested that the biochar addition can enable membrane fouling alleviation and nitrogen removal improvement. The reduced membrane fouling can be ascribed to the biochar adsorption capacity, which facilitates to form bigger flocs with carbon skeleton in biochar as a core. As a result, the biochar addition significantly altered the mixed liquor suspension with soluble microbial product (SMP) concentration reduction of approximately 14%, lower SMP protein/polysaccharide ratio from 0.28 ± 0.02 to 0.22 ± 0.03, smaller SMP molecular weight and bigger sludge particle size from 67.68 ± 6.9 μm to 113.47 ± 4.8 μm. The nitrogen removal is also dramatically improved after biochar addition, which can be due to the initial carbon source release from biochar, and formation of aerobic-anaerobic microstructures. Microbial diversity analysis results suggested more accumulation of denitrification microbes including

    Abstract Cobalt oxide and porous carbon materials are desirable catalysts for peroxymonosulfate (PMS) advanced oxidation reaction in the degradation of organic pollutants. Herein, carbon-coated Co₃O₄ (Co₃O₄/C) mounted biochar (BC) composites (Co₃O₄/C-BC) with a three-dimensional spongy-like network were constructed by driving a dual-precursors of zeolitic imidazolate framework (ZIF-67) and Eichhornia crassipes. Considering the unique structures and compositions, the Co₃O₄/C-BC composites enhanced the dispersion of Co₃O₄/C nanoparticles, minimized the Co leaching, mediated the size of Co₃O₄/C nanoparticles, and enhanced the overall catalytic activity. Co₃O₄/C-BC effectively activated PMS for bisphenol A (BPA) degradation along with satisfactory reusability in advanced oxidation reaction. Electron paramagnetic resonance and radical quenching tests revealed that the generation and effect of sulfate and hydroxyl radicals in reaction process. This work not only provided a promising catalyst for the degradation of organic pollutants but also expanded BPA degradation pathway and PMS activation mechanism.

    Abstract This study investigated the interactions between volatile and char during biomass pyrolysis at 400 °C, employing a β–5 lignin dimer and amino-modified graphitized carbon nanotube (CNT–NH₂) as their models, respectively. The results demonstrated that both –NH₂ and its carrier (CNT) facilitated the conversion of the β–5 dimer, which significantly increased from 9.7% (blank run), to 61.6% (with CNT), and to 96.6% (with CNT–NH₂). CNT mainly favored the breakage of C–O bond in the feedstock to produce dimers with a yield of 55.5%, while CNT–NH₂ promoted the cleavage of both C–O and C–C bonds to yield monomers with a yield up to 63.4%. Such significant changes in the pyrolysis behaviors of the β–5 lignin dimer after the introduction of CNT–NH₂ were considered to be mainly caused by hydrogen-bond formations between –NH₂ and the dimeric feedstock/products, in addition to the π–π stacking between CNT and aromatic rings.

    Abstract Biochar was utilized to intensify constructed wetland (CW) for further organic and nitrogen removal from secondary wastewater. Four sets of non-aerated biochar amended vertical flow CW (VFCW) were developed to investigate the synergistic effects of biochar and microbes on pollutant removal. Results showed that the average COD and nitrogen removal efficiencies of VFCW1 (with 1% w/w biochar with microbe and plants) achieved 89.1 ± 5.6% and 90.2 ± 3.1% respectively, and their corresponding removal rates of 10.2 ± 0.8 mg-COD/(m

    Abstract Purpose: The purpose of the study was to appraise the methodological quality of the highest impact blepharoplasty research and to describe prevalent research themes.
    Methods: The 100 most highly cited research papers relevant to blepharoplasty were obtained from Web of Science, with no journal or date limitations applied. Data extraction included the study design, main research topic and specialty, outcome measures, and citation count. Each paper's level of evidence was independently evaluated by 2 authors according to the Oxford Centre for Evidence-Based Medicine system.
    Results: Overall, the 100 most cited blepharoplasty research papers were cited by 4,194 papers. The mean number of citations for each paper was 73 (range: 42-239). Most of the papers presented level 4 (n = 51) or level 5 (n = 35) evidence, which is consistent with the predominance of case series (n = 47) and expert opinions (n = 18) amongst study designs. No papers achieved level 1 (highest) evidence. Six papers presented level 2 evidence and 8 papers presented level 3. Significant research foci included innovative surgical techniques (n = 65) and anatomical considerations (n = 10), with reconstructive and cosmetic implications. Senior authors were mainly affiliated with centers of plastic (n = 53) or ophthalmic/oculoplastic (n = 34) surgery. Only 3 papers used validated subjective or objective cosmetic outcome measures.
    Conclusions: Despite a significant impact on current practice, the level of evidence of the highly cited blepharoplasty research was predominantly low. Robust research methodology, through well-designed studies and standardized outcome measures, is necessary to facilitate evidence synthesis and guide clinical practice.
