It details how water can alter zeolite acidity by forming hydrogen bonding or hydronium ions through different modes of water in zeolite topologies. Moreover, it summarizes the risks of zeolite stability loss via hydrolysis of Si−O−T bonds to influence the stability, structure, and catalytic reactivity of zeolites. To address water interference, various strategies for water removal from zeolite frameworks are reviewed and proposed from the structural perspective of the zeolites. By combining advanced in-situ techniques, FTIR and solid-state NMR have proven effective in providing atomic-level insights, as they eliminate the masking effects of water to enable precise characterization of the zeolite framework. This work underscores the importance of these methods in minimizing the influence of water, enhancing the reliability of zeolite characterization for catalytic applications, and providing insights into recent advancements, challenges, and future directions in the related fields.","PeriodicalId":72562,"journal":{"name":"Chemistry methods : new approaches to solving problems in chemistry","volume":"5 4","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cmtd.202400076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793347","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}

In this work, we have presented the isolation of two nanoclusters (NCs) [Cu14H10(DMBT)3(PPh3)8][BF4] (Cu14) and [Cu41H21Cl8(DMBT)12(PPh3)6] (Cu41) [DMBT=2,4-dimethylbenzenethiol and PPh3=Triphenylphosphine] upon manipulating the concentration of thiol ligand. A correlation between thiolate ligand's concentration and product selectivity was noticed. Further, the presence of R and S isomerism was observed in Cu14 unit cell. Single Crystal X-ray Diffraction (SC-XRD) data revealed that Cu14 crystallized in the cubic space group Pa-3, while Cu41 in hexagonal space group P63/m. The crystal structure of Cu14 and Cu41 NCs were supported using high resolution electrospray mass spectrometry (ESI MS) and other spectroscopic approaches.

This novel alignment medium facilitates optimal isotropic and anisotropic conditions within a single sample preparation, controlled by sonication, thereby enabling the measurement of anisotropic NMR parameters- residual dipolar couplings (RDC) and residual chemical shift anisotropy (RCSA). GO-d-CP offers several advantages, including ease of synthesis, isolation of solid GO-d-CP as a stable non-hygroscopic material, and maintenance of the anisotropic state stability >30 days, allowing for prolonged and repetitive experiments. Notably, post the analysis it allows for easy recovery of valuable analytes as well as GO-d-CP for reuse, enabling the routine application of anisotropic NMR in structural analysis of small molecules. We demonstrate its efficacy by analyzing the relative stereochemistry of four compounds - estrone, santonin, griseofulvin, and cinmethylin - using anisotropic NMR data.","PeriodicalId":72562,"journal":{"name":"Chemistry methods : new approaches to solving problems in chemistry","volume":"5 4","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cmtd.202400039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793481","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}

In this Review we present and discuss in a critical way the best available physicochemical processes versus modern electrochemical approaches for metal recovery of elements which form part of spent catalysts or other sources such as wastewater, mining waste and spent batteries. These techniques include coagulation/flocculation, precipitation, electrocoagulation/electroflotation, membrane electrolysis, electrodeposition/electrowinning and gas-diffusion electrocrystallization (GDEx). Several key performance indicators (KPIs) are utilized to facilitate the critical analysis of the different recovery methods. Such indicators have to do, for example, with the efficiency, the cost, the complexity, and the environmental friendliness of the methods used. In some cases, the recovered metals can be further used for specific applications, including the fabrication of electrocatalysts for reactions of interest. When possible, the more novel electrified technologies are benchmarked versus the state-of-the art approaches. This manuscript helps to summarize all types of approaches in a comparative manner. When the targeted metal cannot be recovered by any of the technologies explored, its removal can also be considered as satisfactory in some extent, especially if the element under discussion poses a risk of toxicity for the environment or for human health. Recovery technologies are sometimes combined for an optimum effect, exploiting the advantages of each approach and mitigating their drawbacks. Our review provides also some examples for ‘removal-only’ possibilities of the studied methods, though its primary focus is the metal recovery aiming for metal reuse in the best possible scenarios.","PeriodicalId":72562,"journal":{"name":"Chemistry methods : new approaches to solving problems in chemistry","volume":"5 3","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cmtd.202400046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581481","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}

Due to their low toxicity, good solubility, and transport properties resulting from the structure forming the cage, they have gained popularity in imaging-oriented studies. In vitro studies have shown that one of the guests compatible with the CB[n] hosts are Xe atoms, leading to high-resolution 129Xe magnetic resonance signals in pulmonary medical imaging. This prompts the question of whether similar results could be achieved in vivo in other tissues and body fluids. Here, we demonstrate how the varying efficacy of Xe encapsulation by a CB[6] cage is governed by the Na+ : K+ molecular ratio in simulated body fluids. Moving from a high concentration of Na+ to an excess of K+ in the solution significantly increases Xe encapsulation by the macromolecules. This finding indicates chemoselectivity of cucurbit[6]uril host-guest interactions. Since Na+ and K+ are the most abundant ions in human body fluids, our results provide a theoretical foundation for future liquid-state in vivo Xe imaging in medical applications.","PeriodicalId":72562,"journal":{"name":"Chemistry methods : new approaches to solving problems in chemistry","volume":"5 3","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cmtd.202400033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582060","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}
