Abstract Metal ions from natural and anthropogenic sources cause pollution to society and the environment is major concern in the present scenario. The deposition and contamination of metal ions in soil and water affect the biogeochemical cycles. Thus, it threatens the everyday life of living and non-living organisms. Reviews on the detection of metal ions through several techniques (Analytical methods, electrochemical techniques, and sensors) and materials (Nanoparticles, carbon dots (quantum dots), polymers, chiral molecules, metal-organic framework, carbon nanotubes, etc.) are addressed separately in the present literature. This review reveals the advantages and disadvantages of the techniques and materials for metal ion sensing with crucial factors. Furthermore, it focus on the capability of conjugated polymers (CPs) as metal ion sensors able to detect/sense hazardous metal ions from environmental samples. Six different routes can synthesize this type of CPs to get specific properties and better metal ion detecting capability in vast research areas. The metal ion detection by CP is time-independent, simple, and low cost compared to other materials/techniques. This review outlines recent literature on the conjugated polymer for cation, anion, and dual ion sensors. Over the last half decades published articles on the conjugated polymer are discussed and compared.

Abstract Transition metal complexes (TMCs) with strong and long-lived excited state absorption (ESA) usually exhibit high-performance optical power limiting (OPL) response. Several techniques, such as transmission vs. incident fluence curves and Z-scan have been widely used to assess the OPL performance of typical TMCs. The OPL performance of TMCs is highly molecular structure-dependent. Special emphasis is placed on the structure-OPL response relationships of Pt(II), Ir(III), Ru(II), and other metal complexes. This review concludes with perspectives on the current status of OPL field, as well as opportunities that lie just beyond its frontier.

Abstract This paper aims to review recent advances on synthesis, crystal structures, thermal, spectroscopic, phase transitions, optical, dielectric, and catalysis properties of hydrate and anhydrous alkylenediammonium halogenometallates materials (Metal: Bi, Sb, Halogen: Cl, Br, I). These hybrid materials present rich structural diversities based on octahedra forming infinite zero dimensional, 1-dimensional chains, 2-dimensional layers, discrete bioctahedra, and discrete tetramer units. The effect, contribution and importance of hydrogen bonding N–H … X (X: Cl, Br, I) are reviewed in terms of solid state relationship. Particularly, a comparative study is made on hydrate and anyhdrous aliphatic chlorobismuthates with alkylenediammonium +NH3(CH2) n NH3+ based on structural data and V/Z variation with (CH2) n chains (n = 2–8, 12), and variation of BiCl63− Raman frequencies modes versus (CH2) n chains (n = 3–8). Hydrate salts with (n = 3, 12) consist of isolated BiCl63− anions and two water molecules, against others ones with isolated anionic chains [BiCl52−] n or Bi2Cl104− dimers, formed by distorted octahedra BiCl63− sharing corners, vices or edges. The reviewed optical and electronic band gaps suggested interesting compounds with band gaps (1.85–2.4 eV), as suitable materials in optoelectronic properties, photoactive layer in solution-processed photovoltaics, and bio-imaging or photovoltaic applications. It was concluded that iodobismuthate salts have generally the lowest bands gap, compared to that of bromo and chlorobismuthate slats. Catalysis proprieties are reviewed n fast (RhB) degradation under dark conditions for (C4N2H7)4Bi2Cl10, (C5H9N2)BiI4, and {(H-BPA)4·[(BiI6)I13]·2I3} n , and in organic salts synthesis under solvent-free conditions. Herein NH3(CH2) n NH3BiCl5 (n = 5–7) salts were used as highly efficient catalysts, which is a novel tendency in chlorobismuthate researchs in the green chemistry field.
摘要本文综述了水合物和无水亚烷基卤代二铵材料(金属:Bi,Sb,卤素:Cl,Br,I)的合成、晶体结构、热、光谱、相变、光学、介电和催化性能的最新进展。这些杂化材料基于八面体呈现出丰富的结构多样性,八面体形成无限的零维、一维链、二维层、离散的生物八面体和离散的四聚体单元。从固态关系的角度综述了氢键N–H…X(X:Cl,Br,I)的作用、贡献和重要性。特别是,基于结构数据和(CH2)n链的V/Z变化(n=2–8,12),以及BiCl63−拉曼频率模式与(CH2。具有(n=3,12)的水合物盐由分离的BiCl63−阴离子和两个水分子组成,而其他分子则具有分离的阴离子链[BiCl52−]n或Bi2Cl104−二聚体,由扭曲的八面体BiCl63–共享角、副或边缘形成。综述的光学和电子带隙表明,具有带隙(1.85–2.4 eV)的有趣化合物是光电子性能、溶液处理光伏中的光活性层以及生物成像或光伏应用中的合适材料。得出的结论是,与溴和氯铋酸盐相比,碘铋酸盐通常具有最低的带隙。综述了(C4N2H7)4Bi2Cl10、(C5H9N2)BiI4和{(H-BPA)4·[(BiI6)I13]·2I3}n在黑暗条件下的快速(RhB)降解以及在无溶剂条件下的有机盐合成中的催化特性。本文使用NH3(CH2)n-NH3BiCl5(n=5–7)盐作为高效催化剂,这是绿色化学领域氯铋酸盐研究的一个新趋势。

Abstract Bismuth chloride oxide (BiOCl) is a typical V-VI-VII ternary oxide material, which is one of the widely studied metal oxides due to its unique surface, electronic and photocatalytic properties. However, the broad bandgap and the large number of photogenerated electron-hole pair complexes of BiOCl limit its photocatalytic efficiency. Since the photocatalytic performance of BiOCl is highly dependent on its exposed crystallographic facets, research attention has increasingly focused on the different structures and properties possessed by different crystallographic facets of BiOCl. This article reviews the basic principles of using different crystalline surfaces of BiOCl materials to enhance photocatalytic activity, summarizes the applications of BiOCl single-crystal catalysts and composite catalysts in the environmental field, and provides an outlook on the challenges and new research directions for future development in this emerging frontier area. It is hoped that the crystalline surface-related photocatalysis of BiOCl can be used to provide new guidance for the rational design of novel catalysts for various energy and environment-related applications.
摘要氯化铋氧化物(BiOCl)是一种典型的V-VI-VII三元氧化物材料,由于其独特的表面、电子和光催化性能,是被广泛研究的金属氧化物之一。然而,BiOCl的宽带隙和大量的光生电子-空穴对复合物限制了其光催化效率。由于BiOCl的光催化性能高度依赖于其暴露的晶面,研究注意力越来越集中在BiOCl不同晶面所具有的不同结构和性能上。本文综述了利用不同晶面的BiOCl材料提高光催化活性的基本原理,总结了BiOCl单晶催化剂和复合催化剂在环境领域的应用,并展望了这一新兴前沿领域的挑战和新的研究方向。希望BiOCl的晶体表面相关光催化能为合理设计各种能源和环境相关应用的新型催化剂提供新的指导。

Abstract Metal-Organic Frameworks (MOFs) are a class of crystalline materials that, thanks to their large surface area and high porosity, allow them to be used in various areas of knowledge. This diversity of applications is due to the metal ions and the organic binders that compose them, but it is also important to highlight the ability of MOFs to function as hosts for a great variety of molecules of very different sizes and chemical properties. The first existing approaches for incorporating biomolecules in MOFs are discussed: pore encapsulation, surface binding, covalent binding, and in-situ encapsulation. Next, we discuss the obstacles of designing MOFs for effective gene delivery and how to enhance the gene delivery using different strategies.

Abstract Modern cements are complex materials with well-defined compositions that reach to high and consistent results. Automated techniques such as Rietveld analysis lead to provide an understanding of the composition and polymorphism of cement phases that could lead to control of the clinkering conditions to optimize characteristics and consequently quality product. For the characterization of cements used in the construction sector, Rietveld method has significant benefits over other analytical techniques. The precise information about phase assemblage and polymorphism lets monitoring the hydration behavior of binder materials. The objective of this paper is to report the quantitative Rietveld phase analyzes for three industrial clinkers, to review the most recent quantitative X-ray powder diffraction studies on anhydrous cement and to discuss the influence of the different parameters elaborated in the Rietveld method.

Abstract Ruthenium complexes are considered as the most favorable alternatives to traditional platinum-based cancer drugs owing to their acceptable toxicity level, selectivity, variant oxidation states and ability to treat platinum-resistant cancer cells. They have similar ligand exchange kinetics as platinum drugs but can be tailored according to our desire by ligands influence. In the current study, we illustrate the in-vitro anticancer profile of some ruthenium complexes (2016–2021) against human hepatocellular carcinoma (HepG2). The anticancer activity of ruthenium complexes is determined by comparing their IC50 values with one another and positive controls. Fortunately, some ruthenium complexes including 3, 4, 6, 14, 15, 20, 42, and 48 exhibit surpassed in-vitro anticancer profile than that of positive controls promising as potential candidates against liver cancer.

摘要钌配合物被认为是传统的基于铂的癌症药物的最有利的替代品,因为它们具有可接受的毒性水平、选择性、可变氧化态和治疗铂耐药性癌症细胞的能力。它们具有与铂类药物相似的配体交换动力学,但可以根据我们的愿望通过配体的影响进行定制。在目前的研究中,我们阐明了一些钌配合物(2016-2021)对人类肝细胞癌(HepG2)的体外抗癌作用。钌配合物的抗癌活性是通过将它们的IC50值彼此和阳性对照进行比较来确定的。幸运的是,一些钌配合物,包括3、4、6、14、15、20、42和48,表现出超过阳性对照的体外抗癌特性,有望成为癌症的潜在候选物。我们还探讨了结构-活性关系(SAR),这是合理设计和合成钌新药的关键因素。它涵盖了影响抗癌活性的因素,包括亲脂性、平面性、面积和体积、不同配体的空间影响、配体诱导的电子效应、稳定性、水溶性和对靶位点的生物利用度。本文报道的数据将在未来几天为钌抗癌药物的合理设计和合成提供有力支持。

Abstract Graphene-based layered materials have got significant interest in membrane technology for water desalination, gas separation, organic nanofiltration, pervaporation, proton exchange applications, etc. and show remarkable results. Up to date, various methods have been developed for fabrication of high performance membrane. Most of them are only suitable for research purposes, but not appropriate for mass transport barrier and membrane applications that require large-area synthesis. In this comprehensive review, we summarized the current synthesis and fabrication methods of graphene-based membranes. Emphasis will be given on fabrication of both graphene-based nanoporous and lamellar membranes. Finally, we discuss the current engineering hurdles and future research directions yet to be explored for fabrication of such membranes.
石墨烯基层状材料在膜技术中在海水淡化、气体分离、有机纳滤、渗透蒸发、质子交换等方面的应用得到了极大的关注,并取得了显著的成果。迄今为止,人们已经开发出各种制备高性能膜的方法。其中大多数仅适用于研究目的,而不适用于需要大面积合成的传质屏障和膜应用。本文综述了目前石墨烯基膜的合成和制备方法。重点是石墨烯基纳米孔膜和层状膜的制备。最后,我们讨论了目前的工程障碍和未来的研究方向有待探索的制造这种膜。
