Zeolite nanosheets can be used for the fabrication of low-defect-density, thin, and oriented zeolite separation membranes. However, methods manipulating their morphology are limited, hindering progress toward improved performance. We report direct synthesis (i.e., without using exfoliation, etching, or other top-down processing) flat MFI demonstrate use as high-performance membranes xylene isomer separations. Our were synthesized nanosheet fragments seeds instead previously nanoparticles....
Zeolitic imidazolate framework (ZIF-8) is a promising material for gas separation applications. It also serves as prototype numerous ZIFs, including amorphous ones, with broader range of possible applications, sensors, catalysis, and lithography. consists zinc coordinated 2-methylimidazolate (2mIm) has been synthesized methods ranging from liquid-phase to solvent-free synthesis, which aim control its crystal size shape, film thickness microstructure, incorporation into nanocomposites....
Layered double hydroxide (LDH) nanoparticles are effective sorbents for selenium oxoanions but must be fabricated in a suitable fashion implementation water treatment applications using packed columns. In this work, we demonstrate the preparation of nanocomposite beads prepared from Mg–Al–CO3 LDH and chitosan, sustainable biodegradable biopolymer. The synthesis is achieved by direct mixing or situ into chitosan matrix. effect route on structure, maximum loading composite, removal kinetics,...
Selenium is an essential trace element but increasingly becoming a contaminant of concern in the electric power industry due to challenges removing solubilized selenate anions, particularly presence sulfate. In this work, we evaluate granulated layered double hydroxide (LDH) materials as sorbents for selenium removal from wastewaters obtained natural gas plant with aim elucidate effect competing ions on sorption capacities removal. We first present jar test data, followed by small-scale...
Abstract Motivated by the drawbacks of solution phase processing, an all‐dry resist formation process is presented that utilizes amorphous zinc‐imidazolate (aZnMIm) films deposited atomic/molecular layer deposition (ALD/MLD), patterned with electron beam lithography (EBL), and developed novel low temperature (120 °C) gas etching using 1,1,1,5,5,5‐hexafluoroacetylacetone (hfacH) to achieve well‐resolved 22 nm lines a pitch 30 nm. The effects irradiation on chemical structure hfacH etch...

With the adoption of extreme ultraviolet lithography (EUVL) to decrease microelectronic device dimensions, recent photoresist research has focused on development next generation metal-organic resist materials. To enhance lithographic capabilities and mitigate common drawbacks seen from traditional solvent based processes like spin coating solution phase development, interest shifted towards solvent-free "dry" deposition development. These dry techniques can obviate extra processing steps,...
