Abstract Because of their peculiar two‐dimensional layered microstructure, the existence of numerous functionalities on the surface and excellent electrical, thermal and optical features, MXenes are regarded as promising candidates for solving energy and environment related problems. It is noted that energy conversion and storge capability of MXenes could be raised by altering their dimensions, structure, surface chemistry and chemical composition. Therefore, it is critical to recognize how one can boost the relationship between structure and property from applied viewpoint. In the present study, we reviewed the synthesis, properties and potential applications of MXenes. Furthermore, several properties of MXenes including structural, chemical, optical, mechanical and thermal have been explored. In addition, the potential applications of MXenes in various areas such as photocatalysis, gas sensing, supercapacitors, electrocatalysis and environmental remediation have also been discussed. Based on reported works, it can clearly be noticed that features and potential applications of MXenes may be further improved by applying many alteration and functionalization strategies. This study also focuses on the current progresses and future prospective relating to MXene based composites, which will surely assist the scientists who are doing work in areas of academia and material sciences.

Hip and knee joint arthroplasty is a common procedure. The true incidence and predictors of postoperative falls remain uncertain. The aim of this systematic review and meta-analysis is to (1) determine the overall incidence of falls post hip and knee joint arthroplasty, (2) identify risk factors associated with these falls, and (3) evaluate the effectiveness of fall prevention strategies and interventions in reducing fall incidence. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was registered in PROSPERO. This research was conducted using PubMed, Google Scholar, Web of Science, ScienceDirect, and Wiley Online Library. Two independent reviewers screened studies by title, abstract, and full text. The quality of the included articles was assessed using the Methodological Index for Non-Randomized Studies (MINORS). A total of 1,282 publications were identified, leading to the review of 988 patients aged between 60 and 88 years, reviewed for this systematic review from seven full-text articles. Fall incidence post total knee arthroplasty (TKA) varied, with five reporting increased rates (36%, 32.9%, 38.2%, 22.1%, and 32%) and two indicating a decrease (50% and 26.4% reduction). All studies emphasized the role of postoperative limitations and psychological factors on fall risk. Additionally, patients living alone had higher odds of falling, highlighting the need for targeted postoperative care. While fall incidence post hip and knee arthroplasty varies, improvements in quality of life and functional outcomes following surgery are reported. Future research should focus on larger sample sizes, control groups, objective assessments, extended follow-up periods, and various joint replacements.

Proof-of-concept: A polyoxometalate cluster has been used as a highly effective peroxidase mimetic to catalyze H2O2 oxidation of various peroxidase substrates to give colored solutions, leading to a simple, fast, sensitive, and selective assay for H2O2 with a linear range and detection limit of 1–20 and 0.4 μM. This assay was also used for glucose detection both in buffer solution and diluted serum with a linear range and detection limit of 1–10 and 0.5 μM.

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

Polybenzimidazole based composite membranes (65 TSAD, 50 TSAD and 35 TSAD) were prepared by incorporating different amounts (wt %) of inorganic hetero poly acids (IHAD) into polybenzimidazole (PBI) matrix. IHAD was synthesized by reacting silicotungstic acid with tetraethyl orthosilicate (TEOS) in the presence of acid. Structural, morphological and thermal characteristics of all the composite membranes were studied by FT-IR, XRD, SEM and TGA and further investigated functional relationships between the materials structure and metal ion uptake using Hg(II), Pb(II), Y(III), and Cd(II). It was found that composite membranes were more selective toward Y(III), and further uptake capacity of composite membranes is highly reliant on the amount of IHAD contents. The composite membrane containing high IHAD contents (35 TSAD) exhibited high thermal stability and high uptake capacity toward Y(III), which was experimentally determined to be 2.48 mgg−1.
