The pharmaceutical waste, processed or unprocessed, is being released into water systems. This contamination leads to the death of millions of people across the globe annually. Tailored treatment procedures are effectively employed to remove these compounds. However, many of these techniques suffer from high-cost apparatus, generation of secondary pollutants, and sludge etc. Conversely, adsorption combined with photocatalysis is an alternative, economical and efficient method for water remediation. This review delves deeper into the synthesis protocols of biochar derived photocatalysts and investigates their water purification applications. Specifically, studies focusing Fluoroquinolones, Tetracyclines, non-steroidal anti- inflammatory drugs (NSAIDs), Sulfa drugs, anti-bacterial, antiviral and anti-convulsant drugs have been explored. The degradation pathways of these drugs have been elucidated in detail along with the reaction parameters and kinetic studies. Notably, the highest removal efficiency reported to date for these drugs is 100 % with recyclability up to 8 cycles, maintaining minimal efficacy decline. Literature has explained that the use of bare biochar does not perform effectively. On the contrary, combining it with other materials including metal oxides, MOFs, CNTs significantly enhances its efficiency. The practical implementation of BC nanocomposites in the real-world water systems is in infancy and requires scalability. Moreover, the regeneration studies of the photocatalysts are restricted to fewer cycles and needs upgradation. This review aims to open avenues for future research in the domain of photocatalytic degradation of pharmaceutical waste in wastewater.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"26 ","pages":"Article 100721"},"PeriodicalIF":7.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143563744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface electric charge, measured via zeta potential, plays a pivotal role in the flotation separation of these electrode materials. The pH, roasting temperature, thermal treatment duration, and bubbles' presence can significantly influence these materials' surface properties. However, a comprehensive investigation addressing the combined effects of these factors on the zeta potential of electrode active materials is still lacking. This study aims to bridge this gap by systematically exploring the effects of pH (4.5, 7, and 10.5), roasting temperatures (0–500 °C), varied thermal treatment times (1 to 2 h), and the presence or absence of bubbles (nano and microbubbles) on the zeta potential of both anode and cathode materials. The study also examines the impact of conditioning with n-dodecane, a typical flotation collector. While zeta potential is largely pH-dependent, roasting temperature significantly influences surface charge, whereas thermal treatment duration has a minimal effect. Notably, the most considerable zeta potential difference (28.3 mV) between the anode (-18.63 mV) and cathode (9.67 mV) surfaces occurred in the absence of both collector and bubbles, at pH 7, 500 °C, and a thermal treatment time of 2 h. Under conditioning involving bubbles and collector, the highest difference observed was 2.21 mV at pH 7, 250 °C, and 1 h of thermal treatment. These findings contribute to a deeper understanding of surface charge behavior in LIB recycling processes, with implications for improving flotation separation efficiency through surface science and engineering.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"26 ","pages":"Article 100719"},"PeriodicalIF":7.5,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its unique physicochemical properties and cost-effectiveness are essential for wide utilization in biomedicine. However, the effect of morphology of TiN on the photothermal therapy (PTT) efficiency has not been studied yet. Here, TiN nanocrystals of two precisely defined morphologies - nanobars and nanospheres - were prepared by unique pseudomorphic conversion of TiO₂ nanowires and nanospheres via nitridation at 800 °C.
