It registered the highest water contact angle (approximate to 176 degrees) in the MOF domain, marking the first example of an ultrahydrophobic MOF. Various experimental and theoretical studies reinforce its distinc-tive water-repellent characteristics, and the conjugation of superoleophilicity and unparalleled hydrophobicity of a MOF material has been coherently exploited to achieve real-time oil/water separation in recyclable membrane form, with significant absorption capacity performance. This is also the first report of an oil/water separating fluorinated ultrahydrophobic MOF-based membrane material, with potential promise for tackling marine oil spillages.1 aMukherjee, Soumya1 aKansara, Ankit, M.1 aSaha, Debasis1 aGonnade, Rajesh1 aMullangi, Dinesh1 aManna, Biplab1 aDesai, Aamod, V.1 aThorat, Shridhar, H.1 aSingh, Puyam, S.1 aMukherjee, Arnab1 aGhosh, Sujit, K.  uhttps://library.ncl.res.in/content/ultrahydrophobic-fluorous-metal-organic-framework-derived-recyclable-composite-apromising01579nas a2200205   4500008004100000245008700041210006900128260000800197300001400205490000700219520088200226100001801108700002101126700002701147700001701174700001801191700002401209700002101233856011901254       2017                        eng d00aUltrahigh ionic conduction in water-stable close-packed metal-carbonate frameworks0 aUltrahigh ionic conduction in waterstable closepacked metalcarbo  cAUG  a9710-97150 v563 aUtilization of the robust metal-carbonate backbone in a series of water-stable, anionic frameworks has been harnessed for the function of highly efficient solid-state ion conduction. The compact organization of hydrophilic guest ions facilitates water-assisted ion-conduction in all the compounds. The dense packing of the compounds imparts high ion-conducting ability and minimizes the possibility of fuel crossover, making this approach promising for design and development of compounds as potential components of energy devices. This work presents the first report of evaluating ion-conduction in a purely metal-carbonate framework, which exhibits high ion-conductivity on the order of 10(-2) S cm(-1) along with very low activation energy, which is comparable to highly conducting well-known crystalline coordination polymers or commercialized organic polymers like Nafion.1 aManna, Biplab1 aDesai, Aamod, V.1 aIllathvalappil, Rajith1 aGupta, Kriti1 aSen, Arunabha1 aKurungot, Sreekumar1 aGhosh, Sujit, K.  uhttps://library.ncl.res.in/content/ultrahigh-ionic-conduction-water-stable-close-packed-metal-carbonate-frameworks02342nas a2200217   4500008004100000245010300041210006900144260000900213490000700222520157600229100001701805700002201822700001701844700002301861700001701884700001801901700002701919700002601946700002101972856013101993       2024                        eng d00aUltralight crystalline hybrid composite material for highly efficient sequestration of radioiodine0 aUltralight crystalline hybrid composite material for highly effi  cFEB 0 v153 a<p>
	Considering the importance of sustainable nuclear energy, effective management of radioactive nuclear waste, such as sequestration of radioiodine has inflicted a significant research attention in recent years. Despite the fact that materials have been reported for the adsorption of iodine, development of effective adsorbent with significantly improved segregation properties for widespread practical applications still remain exceedingly difficult due to lack of proper design strategies. Herein, utilizing unique hybridization synthetic strategy, a composite crystalline aerogel material has been fabricated by covalent stepping of an amino-functionalized stable cationic discrete metal-organic polyhedra with dual-pore containing imine-functionalized covalent organic framework. The ultralight hybrid composite exhibits large surface area with hierarchical macro-micro porosity and multifunctional binding sites, which collectively interact with iodine. The developed nano-adsorbent demonstrate ultrahigh vapor and aqueous-phase iodine adsorption capacities of 9.98 g.g-1 and 4.74 g.g-1, respectively, in static conditions with fast adsorption kinetics, high retention efficiency, reusability and recovery. The development of effective adsorbents of radioiodine nuclear waste remains difficult due to the lack of proper material design strategies. Here the authors report an ultralight hierarchically porous crystalline multifunctional hybrid nanocomposite for ultrafast entrapment of iodine and polyiodide species under both static and dynamic condition.</p>
