“…Although only several PS spheres are partially located on the HKUST-1 crystal surface, most are embedded in the MOF crystals (Fig. 1h,i) 4 ] À , Au NPs and ferritin are fully encapsulated in the HKUST-1 host and do not escape during HKUST-1 crystal growth. PS spheres and SWCNTs are sufficiently large to be visible in SEM images ( Fig.…”

“…M etal-organic frameworks (MOFs) 1,2 , which are selfassembled from organic ligands and metal ions, are highly promising porous crystalline materials with the strong potential for gas separation [3][4][5][6][7][8][9][10][11][12][13][14] , chemical sensors [15][16][17][18] , catalysts [19][20][21][22] and optical devices 23 because of their large and accessible specific surface areas, uniform and tunable pore sizes, and diverse properties. However, to further enrich or expand the functionalization of MOFs, in an approach similar to zeolites [24][25][26] , new synergistic properties have been achieved by incorporating functional species into MOFs to form composite materials that cannot be obtained from the parent MOF counterparts 27 .…”

Porous metal-organic frameworks (MOFs) demonstrate great potential for numerous applications. Although hetero-functional components have been encapsulated within MOF crystalline particles, the uniform incorporation of functional species with different sizes, shapes and functions in MOF thin films with dual properties, especially at room temperature and without the degradation of the MOF framework, remains a significant challenge towards further enriching their functions for various purposes. Here we report a general method that can rapidly encapsulate diverse functional components, including small ions, micrometresized particles, inorganic nanoparticles and bioactive proteins, in MOF thin films at room temperature via a metal-hydroxide-nanostrand-assisted confinement technique. These functional component-encapsulated MOF composite thin films exhibit synergistic and size-selective catalytic, bio-electrochemical, conductive and flexible functionalities that are desirable for thin film devices, including catalytic membrane reactors, biosensors and flexible electronic devices.

Ich wyjątkowe cechy: dowolność doboru elementów składowych umożliwiająca uzyskanie biozgodnych struktur oraz dobrze rozwinięta powierzchnia właściwa sprawiają, że MOF-y są obiecującymi nośnikami substancji leczniczych. MOF-y mogą być wykorzystane również w tzw. terapii celowanej, dzięki dołączonym do powierzchni nośnika ligandom lub przeciwciałom. Poprzez wbudowanie w strukturę kationów o właściwościach paramagnetycznych będzie możliwe użycie ich jako kontrastu w tomografii magnetyczno-rezonansowej (MRI). Połączenie zdolności przenoszenia cząsteczek substancji leczniczych i obrazowania w jednym nośniku wskazuje na potencjalne zastosowanie MOF-ów jako teranostyków i może dawać możliwość monitorowania substancji leczniczej w czasie rzeczywistym po wprowadzeniu do organizmu. Celem niniejszej pracy jest charakterystyka nowej grupy związków i prezentacja potencjalnych możliwości ich zastosowania jako substancji pomocniczych w technologii postaci leku (Polim. Med. 2015, 45, 2, 81-93).Słowa kluczowe: polimery koordynacyjne, układy mezoporowate, teranostyki, sieci metaloorganiczne. AbstractMetal-organic frameworks (MOFs) belong to the new class of mesoporous, hybrid materials composed of metal ions and organic binding ligands. Their unique features: wide range of chemical building components, which enables obtaining biocompatible materials, and high surface area and loading capacity, make them promising drug delivery vehicles for therapeutic agents. The ability to tune their structures and porosities provides better adjustment for adsorbed drug molecule. Moreover, MOFs functionalized with ligands or antibodies can be used in cancer targeted therapy. Through the incorporation of paramagnetic metal ions into the structure, MOFs are suited to serve as magnetic resonance imaging (MRI) contrast agents. Combining drug delivery ability with imaging properties of MOFs indicates their potential use as theranostic agents and makes possible monitoring drug delivery within the body after administration in the real time. The aim of the present study is to characterize a new class of compounds and to present potential possibilities of their use as excipients in pharmaceutical technology (Polim. Med. 2015, 45, 2, 81-93).Key words: mesoporous materials, coordination polymers, theranostics, metal-organic frameworks. Sieci metaloorganiczne (MOF -metal organic frameworks) to zupełnie nowa grupa materiałów porowatych, która pojawiła się pod koniec lat 90. XX w. Są to związki o budowie hybrydowej organiczno-nieorganicznej, określane również jako porowate sieciowe polimery koordynacyjne PCP (porous coordination polymers). Strukturę MOF stanowi sieć składająca się z dwóch głównych elementów: kationów lub...

This work evaluates the use of aluminum contained in the aluminum-polyethylene films as anodic electrodes using the electrocoagulation technique to reduce the pollutant contents of industrial wastewater quickly and effectively. Thermal treatment at 500°C produces pure aluminum (according to TGA and SEM/EDS analysis) which is used to construct aluminum disks (applying 6 tons/cm 2 of pressure). Aluminum disks are used as cathodes and anodes in an electrochemical cell. The current density applied in the recovered Al electrodes was 12 mA cm -2 , and the maximum COD reduction of wastewater was 77 % at 25 min of treatment. The color and turbidity reductions are 87 and 90 %, respectively. The resulting sludge of wastewater treatment was thermally treated and a second aluminum recovery was reached; since the organic material present in the sludge was removed by the high temperature, the obtained aluminum was pure enough for its reuse. The use of aluminumpolyethylene films as electrodes in the electrocoagulation process contributes to the pollutant removal without the addition of chemical reagents or changing the pH, so it is both effective and environmentally friendly.
