Since the advent of thin-film composite polyamide membranes brought forth a breakthrough in desalination and water purification nearly half century ago, recent years have only witnessed marginal improvements water-salt selectivity these membranes. The slow progression is partly attributable to limited understanding membrane synthesis–structure–performance relationships. A centralized archive reverse osmosis (RO) characterization data may lead shared features that maximize RO performance...
An advanced synthesis protocol for the preparation of Thin-Film Nanocomposite (TFN) membranes is presented.
Abstract Metal–organic frameworks (MOFs) enable the design of host–guest systems with specific properties. In this work, we show how confinement anthracene in a well‐chosen MOF host leads to reversible yellow‐to‐purple photoswitching fluorescence emission. This behavior has not been observed before for anthracene, either pure form or adsorbed other porous hosts. The photoresponse system is caused by photodimerization which greatly facilitated pore geometry, connectivity, and volume as well...
A simple solvent- and catalyst-free method is presented for the synthesis of large-pore metal–organic framework (MOF) MAF-6 (RHO-Zn(eIm)2) based on reaction ZnO with 2-ethylimidazole vapor at temperatures ≤100 °C. By translating this to a chemical deposition (CVD) protocol, crystalline films material could be deposited first time entirely from phase. combination positron annihilation lifetime spectroscopy (PALS) Kr physisorption measurements confirmed porosity these MOF-CVD size supercages...
Following current strong demands from, among others, paper, food and mining industries, a novel type of nanofiltration membrane was developed, which displays excellent performance in terms selectivity/flux with unique combination chemical stability over the full (0-14) pH-range thermal up to 120 °C. The consists polyvinylidene fluoride grafted polystyrene sulfonic acid. optimum showed water permeances 2.4 L h-1 m-2 bar-1 while retaining NaCl, MgSO4 Rhodamine B (479 Da) for respectively ≈60%,...
Robust and scalable thin-film deposition methods are key to realize the potential of metal-organic frameworks (MOFs) in electronic devices. Here, we report first integration chemical vapor (CVD) MOF coatings a custom reactor within cleanroom setting. As test case, MOF-CVD conditions for zeolitic imidazolate framework-8 optimized enable smooth, pinhole-free, uniform thin films on full 200 mm wafers under mild conditions. The single-chamber process impact parameters elucidated via combination...
We introduce a newly developed instrument for 22Na-based positron-annihilation lifetime spectroscopy (PALS) with in-situ temperature, pressure and atmosphere control. The system is designed PALS measurements of samples in changing atmospheric conditions, from vacuum (∼10−5 mbar) up to gas 20 MPa. Furthermore, we can select the composition applied gas, such as N2, Ar, Ar/H2, CO2 well CH4 adjust sample temperature room 200 °C. To test measurement principle, carried out on semi-crystalline...
The landscape of possible polymorphs for some metal–organic frameworks (MOFs) can pose a challenge controlling the outcome their syntheses. Demonstrated here is use template to control in vapor-assisted formation zeolitic imidazolate framework (ZIF) powders and thin films. Introducing small amount either ethanol or dimethylformamide vapor during reaction between ZnO 4,5-dichloroimidazole results porous ZIF-71 phase, whereas other conditions lead dense ZIF-72 phase amorphous materials....
The drive to expand the implementation of membrane separation technology towards harsher environments prompted development chemically robust epoxide-based TFC membranes. This work delves into formation poly(epoxyether) (PEE) thin films via interfacial initiation polymerization (IIP) and an additional cross-linking step (XL-PEE) on top porous support layers, seeking better understand influence performance properties. A systematic study was conducted using a series supports with pore sizes...
