In this study, series of CeZrMnO/r-AlO catalysts were prepared by impregnation method and explored to co-purification of NO and Hg at low temperature. The physical and chemical properties of the catalysts were investigated by XRD, BET, FTIR, NH-TPD, H-TPR, and XPS. The experimental results showed that 10% CeZrMnO/r-AlO yielded higher conversion on co-purification of NO and Hg than the other prepared catalysts at low temperature, especially at 200-300 °C. 91% and 97% convert rate of NO and Hg were obtained, respectively, when 10% CeZrMnO/r-AlO catalyst was used at 250 °C. Moreover, the presence of HO slightly decreased the removal of NO and Hg owing to the competitive adsorption of HO and Hg. When SO was added, the removal of Hg first increased slightly and then presented a decrease due to the generation of SO and (NH)SO. The results of NH-TPD indicated that the strong acid of 10% CeZrMnO/r-AlO improved its high-temperature activity. XPS and H-TPR results showed there were high-valence Mn and Ce species in 10% CeZrMnO/r-AlO, which could effectively promote the removal of NO and Hg. Therefore, the mechanisms of Hg and NO removal were proposed as Hg (ad) + [O] → HgO (ad), and 2NH/NH (ad) + NO (ad) + NO (g) → 2 N + 3HO/2H, respectively. Graphical abstract ᅟ.

Mismatched electron and proton transport rates impede the manifestation of effective performance of the electrocatalytic oxygen evolution reaction (OER), thereby limiting its industrial applications. Inspired by the natural protein cluster in PS-II, different organic-inorganic hybrid electrocatalysts were synthesized via a hydrothermal method. -Toluidine (PT), benzoic acid (BA), and -aminobenzoic acid (PABA) were successfully intercalated into NiFe-LDH.

Background: Colorectal cancer (CRC) is the third most common cancer in the United Kingdom and the second largest cause of cancer death.
Aim: To develop and validate a model using available information at the time of faecal immunochemical testing (FIT) in primary care to improve selection of symptomatic patients for CRC investigations.
Methods: We included all adults (≥ 18 years) referred to Nottingham University Hospitals NHS Trust between 2018 and 2022 with symptoms of suspected CRC who had a FIT.

Titanium disulfide quantum dots (TiSQDs) has garnered significant research interest due to its distinctive electronic and optical properties. However, the effectiveness of TiSQDs in electromagnetic interference (EMI) shielding is influenced by various factors, including their size, morphology, monodispersity, tunable bandgap, Stokes shift and interfacial effects. In this study, we propose a systematic approach for the synthesis of TiSQDs with small size (3.

The recovery of valuable materials from spent lithium-ion batteries (LIBs) has experienced increasing demand in recent years. Current recycling technologies are typically energy-intensive and are often plagued by high operation costs, low processing efficiency, and environmental pollution concerns. In this study, an efficient and environmentally friendly dielectrophoresis (DEP)-based approach is proposed to separate the main components of "black mass" mixtures from LIBs, specifically lithium iron phosphate (LFP) and graphite, based on their polarizability differences.

Annually, thousands of individuals suffer from skin injuries resulting from trauma, surgeries, or diabetes. Inadequate wound treatment can delay healing and increase the risk of severe infections. In this context, a promising synthetic polymer with potent antimicrobial properties, Poly{2-[(methacryloyloxy)ethyl]trimethylammonium chloride} (PMETAC), is synthesized and crosslinked with N,N'-Methylenebis(acrylamide) (BIS) in the presence of Chitosan (CH), a natural, biocompatible polysaccharide that promotes cell regeneration and provides additional beneficial properties.
