Nanotechnology is the most innovative field of the twenty-first century. Worldwide, intensive research is being done to commercialize nano products. Due to their unique or improved physical and chemical properties relative to bulk material, nanomaterials, especially nanoparticles have seen an enormous interest over the past few decades. As environmentally benign alternative nanoparticles are currently being produced “biologically” by means of plant or microorganism-mediated synthesis. Due to its outstanding biocompatibility, affordability, and low toxicity, and cost-effectiveness, ZnO NPs have emerged as one of the most widely used metal oxide nanoparticles in various applications. Interestingly, due to its multiple medical, health, environmental, and economic advantages, the green technique of synthesis employing plant materials has been discovered to be suitable for the production of ZnO nanoparticles. A variety of characterization methods have been used to assess the characteristics of ZnO NPs produced with green strategies, including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), and UV–Vis spectroscopy and others. The value of these techniques reveals important information about the structural, morphological, and optical characteristics of ZnO NPs. In order to support future biomedical and other research, this review provides an overview of recent developments in the green synthesis of ZnO NPs with a focus on natural sources such as plants, bacteria, fungi, and algae as well as their characterizations, and various applications, including, antimicrobial, anticancer, antioxidant, photocatalytic, anti-inflammatory, anti-diabetics, and anti-aging applications.

Polyoxometalates (POMS) are a class of mineral clusters of transition metals or rare-earth elements linked together by Oxo ligands. POMs have been identified as antibacterial, antiviral, and anticancer agents after decades of research since the onset of the 20th century. Furthermore, in recent years POMs have been studied for their applications in diagnosis, photodynamic therapy, photothermal therapy, and theragnostic. However, these last-mentioned POM applications have rarely been reviewed. Considering the potential characteristic features of POMs, comprising their easy, inexpensive, and scalable synthesis, and with special attention to the challenges of their application, POMs would be great alternatives to many conventional medical tools in the field of cancer treatment and diagnosis. In this review, we report recent updated research around utilizing POMs in cancer diagnosis and theragnostic. Publications are on basic topics including POMs in magnetic resonance imaging (MRI), POMs in computed tomography (CT), POMs in cancer photoluminescence (PL) imaging, POMs in multimodality, POMs in radiation therapy applications, POMs as radiosensitizer and promotor of drug release, and POMs in theragnostic applications. It is hoped that this review paper will be useful for those researchers who are interested in expanding the applications of polyoxometalates in the field of cancer treatment and diagnosis.

Photocatalysis is an effective way to alleviate the energy crisis and environmental pollution. Bismuth Chloride Oxide (BiOCl) is one of the most widely studied metal oxides due to its unique surface and electronic structure. However, the wide band gap of BiOCl and the high complexation rate of photogenerated electron–hole pairs limit its photocatalytic efficiency. Increasingly, efforts are being made to improve the performance of this range of photocatalysts. The article reviews the progress of research to enhance the photocatalytic activity of BiOCl nanomaterials. Strategies to improve the photocatalytic performance of single-phase BiOCl include morphological control, component adjustment, crystal facet control, and defects construction. Strategies to improve the photocatalytic activity of BiOCl-based composites include surface modification, immobilization of photocatalysts, impurity doping, and the construction of heterojunctions. In addition, the challenges and trends of BiOCl photocatalysts are discussed and summarized. Hopefully, this review will be helpful for the research and application of BiOCl photocatalysts.

Abstract Recently, strontium oxide nanoparticles (SrO NPs) have become the center of attention due to potential features and promising applications. The physicochemical approaches possess many limitations including extreme experimental conditions, highly complex instruments and use of hazardous chemicals. An eco-friendly and sustainable approach from biogenic sources for formation of SrO NPs is an emerging trend nowadays to effectively replace conventional approaches. This review study all those aspects that facilitate the reader for understanding all biogenic approaches of SrO NPs for their use in different applications with less toxicity issues. In this study, firstly we discuss in detail about plant and other biogenic assemblies based on the synthesis of SrO NPs after which parameters affecting the synthesis of SrO NPs are discussed and finally excellent biomedical applications of SrO NPs along with mechanism are summarized. The literature also showed that green synthesized SrO NPs are highly biocompatible in nature and showed excellent anti-bacterial, anti-oxidant and anti-fungal potential. Hence, this study will provide an understanding to researchers about recent trends for the formation of SrO NPs through different biogenic assemblies and their potential biomedical applications.

Abstract Covalent Organic Frameworks (COFs) represents a class of remarkable porous materials composed of organic building blocks that are covalently linked in a periodic manner to form crystalline structures. High surface area, high porosity, tunable pore size, and high stability are their exceptional properties, which make them attractive candidates for various applications in the fields of catalysis, energy storage devices, biomedical applications, gas separation and storage applications. In fact, the great interest shown in COFs gave us a stimulus to review the output of the recent substantial efforts in this area. Meanwhile, the development of portable and sophisticated systems based on these particles is believed to create deeper insights for the scientists to embark on new investigations to pave the way for discovering new fundamental characteristics of COFs, modifications. Furthermore, the effect of modifications/fractionalizations on the performance of COFs will be thoroughly explained and challenging problems are mentioned. Moreover, the paper covers an inclusive collection of referenced recent research articles, providing readers with a comprehensive understanding of the subject matter and an extensive bibliography for further exploration. Through this comprehensive overview, the paper alleviates the noteworthy contributions of COFs in driving innovation and progress in a range of key scientific disciplines.

Abstract Acyclic diaminocarbenes (ADCs)–Metal complex having strong donor ability and thermal stability led to extensive usability across every area of inorganic and organometallic chemistry. The unique properties of acyclic diaminocarbenes (ADCs) provide certain advantages over other carbene ligands and have the potential to make a great impact in catalysis. Further, the straightforward synthesis of M–ADCs (metal bound acyclic diaminocarbenes) complexes via metal-mediated reaction provides a wide range of well-defined metal carbene catalysts, which might inspire more researchers to devise unsymmetrically substituted, chiral, and novel acyclic carbene compounds. Although the above synthetic route is limited to a few late transition metals, but have great opportunities to expand the scope of this method. The application of M–ADCs complexes as a catalyst for several organic transformation reactions such as various cross-coupling reactions and asymmetric synthesis like hydroarylation, hydroazidation, hydroamination, cyclization and addition reactions which have shown comparable or even higher activities than the analogous M–NHCs based on all the reports presented. Recent findings of donor ability of several ADC ligands would be useful in fine-tuning the electronic properties, and then a catalyst with a certain combination of donicity and steric requirement could open new doors in catalytic reactivity. Thus, the objective of this review is to assess the recent growths that have been made in designing novel and chiral ADCs ligands and synthesizing ADCs–Metal complexes and to highlight catalytic activities of metal acyclic diaminocarbene complexes for cross-coupling reactions.

Abstract This review explores the role of 2-(2′-Pyridyl)imidazole (PyimH) as a coordinating ligand and also its role as a supramolecular agent through hydrogen bonding and π⋯π interaction. Two N coordination sites make 2-(2′-Pyridyl)imidazole an analogous ligand to 2,2′-bipyridine. The syn orientation of imidazole and pyridine sp 2 nitrogen makes it a bidentate chelating ligand. PyimH mainly produces discrete coordination complexes (0D), but in a few cases, 1D coordination polymers are observed due to bridging co-ligands like oxalate, dicyanamide, tricyanomethanide, croconate, thiocyanate, and iso-thiocyanate. These discrete coordination units and co-ligand bridged 1D coordination polymers are further augmented to higher dimensional supramolecular systems having linear, zig-zag, ladder-shaped, ribbon-like, and helical geometry. These supramolecular structures are stabilized by intermolecular hydrogen bonding interaction (N–H⋯N, N–H⋯O, O–H⋯N, O–H⋯O, and C–H⋯O) and π⋯π interaction capability of PyimH ligand. PyimH generally acts as an excellent chelating ligand for a range of metal ions and is also a capable supramolecular glueing agent due to hydrogen bonding and π-stacking ability.
本文综述了2-(2 ' -吡啶基)咪唑(PyimH)作为配位体的作用，以及它通过氢键和π⋯π相互作用作为超分子剂的作用。两个N配位使2-(2′-吡啶基)咪唑成为类似于2,2′-联吡啶的配体。咪唑和吡啶sp 2氮的同向取向使其成为双齿螯合配体。PyimH主要产生离散配位配合物(0D)，但在少数情况下，由于桥接的共配体，如草酸盐、二氰酰胺、三氰甲烷、croconate、硫氰酸盐和异硫氰酸盐，可以观察到一维配位聚合物。这些离散配位单元和共配体桥接的一维配位聚合物进一步扩展到具有线性、锯齿形、阶梯形、带状和螺旋几何形状的高维超分子体系。这些超分子结构通过分子间氢键相互作用(N - h⋯N, N - h⋯O, O - h⋯N, O - h⋯O和C-H⋯O)和PyimH配体的π⋯π相互作用能力来稳定。PyimH通常作为一系列金属离子的优秀螯合配体，由于氢键和π堆积能力，它也是一种功能强大的超分子胶合剂。

Abstract Volatile organic compounds (VOCs) are considered one of the significant contributors to air pollution because they are toxic, difficult to remove, come from a wide range of sources, and can easily cause damage to the environment and human health. There is an urgent need for effective means to reduce their emissions. The current treatment technologies for VOCs include catalytic oxidation, adsorption, condensation, and recovery. Catalytic oxidation technology stands out among the others thanks to its high catalytic efficiency, low energy requirement, and lack of secondary pollution. The difficulty of this technology lies in the development of efficient catalysts. The research on loaded noble metal catalysts and non-noble metal oxide catalysts in this area over the past few years is briefly described in this work. Firstly, the catalytic destruction mechanism of organic volatile compounds is introduced. Secondly, the effects of structural modulation during catalytic oxidation, such as the adjustment of noble metal particle size and morphology, metal doping, and defect engineering, on the conformational relationships are discussed. Finally, the challenges faced by thermal catalytic oxidation for the degradation of VOCs are discussed, and the prospects for its development are presented.
