On‐demand uranium extraction from seawater (UES) can mitigate growing sustainable energy needs, while high salinity and low concentration hinder its recovery. A novel anionic metal‐organic framework (iMOF‐1A) is demonstrated adorned with rare Lewis basic pyrazinic sites as uranyl‐specific nanotrap serving as robust ion exchange material for selecti...

Metal-organic frameworks (MOFs) have been a research hotspot for the last two decades, witnessing an extraordinary upsurge across various domains in materials chemistry. Ionic MOFs (both anionic and cationic MOFs) have emerged as next-generation ionic functional materials and are an important subclass of MOFs owing to their ability to generate stro...

The excessive use of anthropogenic wastes, such as emerging antibiotics and pesticides, has led to serious water pollution. Therefore, selective identification of those specific types of pollutants in wastewater is of significance owing to their direct detrimental impact upon human health. For practical requirements, a potential sensory material is...

Triboelectric nanogenerators (TENGs) are receiving significant attention lately as efficient mechanical energy harvesting devices. They are finding multiple uses in numerous low-power applications. Current TENG designs, although innovative, fall short on practical demands like performance tunability, modulatory, and stability. This invites further...

Ein anionenaustauschbares hybrides Aerogel‐Komposit wird von Sujit K. Ghosh und Mitarbeitern in ihrem Forschungsartikel vorgestellt (DOI: 10.1002/ange.202203385). Die Synthese gelang durch Implantierung eines kationischen metallorganischen Polyeders in ein hierarchisch poröses metallorganisches Gelmaterial. Das Material bindet verschiedene metallba...

Metal-based oxoanions are potentially toxic pollutants that can cause serious water pollution. Therefore, the segregation of such species has recently received significant research attention. Even though several adsorbents have been employed for effective management of chemicals, their limited microporous nature along with non-monolithic applicabil...

The role of the organic building units of MOFs towards selective detection of a targeted metal cation (Fe3+) has been demonstrated by systematic screening by varying the number of Lewis basic (pyridyl‐N atoms) sites in a series of isostructural metal–organic frameworks (MOFs). All three fluorescent MOFs are seen to present a quenching response towa...

The potential emergence of fluorescence‐based techniques has propelled research towards developing probes that can sense trace metal ions specifically. Although luminescent metal‐organic frameworks (MOFs) are well suited for this application, the role of building blocks towards detection is not fully understood. In this work, a systematic screening...

Large-scale uranium extraction from seawater (UES) is widely considered as reconciliation to increasing global energy demand and climate change crises. However, an ideal uranium sorbent combining features of high capacity,...

Thanks to a bottom-up Lego® design of metals and organic ligands, the library of metal-organic frameworks (MOFs) have seen a conspicuous growth. Post-synthetically modified MOFs comprise a relatively smaller subset of this library. Whereas the approach of post-synthetic modification was seminally introduced to MOFs in the early 90's, earliest examp...

Water pollution from heavy metals and their toxic oxo-anionic derivatives such as CrO42-, Cr2O72-, HAsO42-, and HAsO32- has become one of the most critical environmental issues. To address this, herein, we report a new hydrolytically stable luminescent Zn(ii) based cationic metal organic framework (MOF), iMOF-4C, which further successfully exhibite...

Hydrogen sulfide (H2S) is a highly poisonous gas that, when in a work place, must be identified immediately at concentrations greater than 10 ppm. Although there are numerous reports on sensing H2S gas using various techniques and approaches, there still exist a gap in terms of limit of detection (LOD) and feasibility. In this work, we demonstrate...

A triboelectric nanogenerator (TENG) based on natural seeds and electrospun PVDF fibres is reported. The nanofibers are specifically used to enhance the triboelectric effects. A mustard (flax) seed based TENG renders an impressively high electrical output with an average open circuit voltage of 84 V (126 V) and maximum power density 334 mW m-2 (324...

Metal–organic polyhedra (MOP) are a promising class of crystalline porous materials with multifarious potential applications. Although MOPs and metal–organic frameworks (MOFs) have similar potential in terms of their intrinsic porosities and physicochemical properties, the exploitation of carboxylate MOPs is still rudimentary because of the lack of...

The frontispiece shows a phenanthroline-functionalized CdII aminoterephthalate metal–organic framework with dual attributes of CO2-selective adsorption properties and differential photoluminescence signatures induced by phenolic guests of varying electronic nature. The inherently guest-free, rigid amine-rich framework exhibits substantial CO2-selec...

The inherently guest-free, rigid amine-rich framework exhibits substantial CO2-s...

The present study is focused on phytochemical screening of methanol leaf extracts of A. marmelos and the development of phytochemical parameters and to investigate the antifungal substances present in methanolic extract obtained from leaves of A. marmelos plant. Preliminary phytochemical screening of the extracts revealed the presence of flavonoids...
