The paper presents the results of microwave synthesis a Zn-B-P-oxide catalyst, which actively absorbs energy radiation, applied to surface an aluminum-reinforced Al/γ-Al2O3 carrier, in order further intensify process acylation diethylamine with m-toluic acid diethylamide (DETA) under conditions exposure field. ob-tained demonstrate possibility realizing thermal regime, is formed reaction zone d...
nanoparticles of the zno and tio2 were synthesized and the physicochemical properties of the compounds were characterized by ir, x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem). the xrd patterns of the zno and tio2 nanoparticles could be indexed to hexagonal and rutile phase, respectively. aggregated nanoparticles of zno and tio2 with spher...
The characterization and catalytic performance of Zn/ZSM-5 Zn-B/ZSM-5 catalysts in the n-hexane aromatization was reported. Catalysts were prepared by post-synthesis ion exchange thoroughly characterized means XRD, Py-FTIR, N2 adsorption, 27Al 11B MAS NMR spectroscopy electron microscopy techniques. incorporation zinc reduces Brønsted acid site density increases Lewis acidic sites final ZSM-5 b...
Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...
Purpose – The paper’s aim is to show the development of materials and methods which allow freeform fabrication of macroscopic Zn-air electrochemical batteries. Freedom of geometric design may allow for new possibilities in performance optimization. Design/methodology/approach – The authors have formulated battery materials which are compatible with solid freeform fabrication (SFF) while retaini...
BACKGROUND Redox-active iron, a catalyst in the production of hydroxyl radicals via the Fenton reaction, is one of the key participants in ROS-induced tissue injury and general inflammation. According to our recent findings, an excess of tissue iron is involved in several airway-related pathologies such as nasal polyposis and asthma. OBJECTIVE To examine the anti-inflammatory properties of a ...
