TL;DR: This catalyst was found to bypass the presulfurization process, showing promise as an alternative to sulfided catalysts for green diesel production.

Abstract: To investigate the influence of different dispersed phases on polyamide (PA)/ZIF-8 membrane properties, three different fabrication methods for dispersing ZIF-8 nanoparticles were developed to prepare the PA/ZIF-8(A) membranes (in aqueous phases), PA/ZIF-8(O) membranes (in organic phases), and PA/ZIF-8(B) membrane (in both the aqueous and organic phases), respectively. These PA/ZIF-8 membranes were characterized in detail by XRD, DLS, XPS, FTIR, SEM, AFM, and contact angle measurements, the results showed that the structure properties of the PA/ZIF-8 membranes were significantly dependent on the dispersed phases and ZIF-8 concentrations. The nanofiltration performance of the PA/ZIF-8 membranes was investigated for application in removing dye (Congo red) from water. For the PA/ZIF-8(A) and PA/ZIF-8(O) membranes, the flux and rejection were both improved at 0.05–0.15% (w/v) ZIF-8 concentration in a single phase and the PA/ZIF-8(O) membranes exhibited slightly higher fluxes than the PA/ZIF-8(A) membranes due to the better dispersion of hydrophobic ZIF-8 in organic phases. The PA/ZIF-8(B) membrane prepared by 0.10% (w/v) ZIF-8 concentration in both the aqueous and organic phases showed the best membrane performance among all prepared PA/ZIF-8 membranes: the flux significantly increased to two times that of the pure PA membrane, and the rejection was nearly 100%. Compared with the PA/ZIF-8(A) and PA/ZIF-8(O) membranes, the improvement on membrane performance of the PA/ZIF-8(B) membrane was achieved by a combination of the high ZIF-8 loading, good ZIF-8 distribution, and fewer ZIF-8 aggregates in the PA/ZIF-8 selective layer.

TL;DR: In this paper, a controlled route for straightforward synthesizing novel microporous nanocomposites of ZIF-8 type metal-organic frameworks material incorporated with multiwalled carbon nanotubes (MWNTs) was reported.

TL;DR: The in vitro cytotoxicity and in vivo tumor growth inhibition studies in LLC-tumor bearing mice supported that the formulation developed in this work exhibited great potential as an effective tumor targeting delivery system for insoluble anticancer drugs.

TL;DR: In this paper, the thermal degradation of cellulose- graft -poly( l -lactic acid) at different heating rates in nitrogen was studied by thermogravimetric analysis (TGA) in the temperature range 20-550°C.
