A composite material consisting of carbon nanofibers (CNFs) grown on sintered metal fiber filters was modified by H2O2 or plasma-generated O3. Coupling temperature programmed desorption (TPD) and X-ray photoelectron spectroscopy (XPS) techniques in the sam ...
Enantioselective rhodium(I)-catalyzed reactions of tert-cyclobutanols, e.g. I, lead to indanones with quaternary stereogenic centers, e.g. II, via consecutive C-C/C-H/C-C bond activations. ...
Master sintering curve (MSC) was used as a practical approach to analyse the sintering behavior of an ultrafine alumina powder. Non-isothermal sintering was carried out at three heating rates. The concept of the MSC has been used to investigate the effect ...
The behavior of As in the subsurface environment was examined along a transect of groundwater monitoring wells at a Superfund site, where enhanced reductive dechlorination (ERD) is being used for the remediation of groundwater contaminated with chlorinated ...
In order to mitigate climate change, the countries that ratified the Kyoto protocol agreed to lower their greenhouse gas emissions during the period 2008-2012 of 5% on average compared to their emissions of 1990. Carbon separation and storage (CSS) process ...
This study addresses the design of riprap aprons as a scour countermeasure near abutments under clear-water conditions. It deals with the lateral extent of riprap aprons and the geometry of the scour hole prevailing at the apron edge. The study applies to ...
This study investigates the droplet formation characteristics of secondary organic aerosol (SOA) formed during the ozonolysis of sesquiterpene β-caryophyllene (with and without hydroxyl radicals present). Emphasis is placed on understanding the role of sem ...
The interfaces: K/Cu(115) and CO/Cu(115) have been characterized using surface sensitive techniques, including low energy electron diffraction and photoelectron spectroscopy. K adatoms show tendency to occupy the sites close to the step edges. At low tempe ...
The aim of our experiments was the production of helically coiled carbon nanotubes selectively. The influence of catalytic particles prepared by ball milling (dry and wet method) was investigated on the growth. of coiled carbon nanotubes under conditions. ...
We previously reported the synthesis and the antimycobacterial activity of 4-(7,7-dimethyl-7H-furo[3,2-f]chromen-2-yl)pyridine. From this result, we sought to design simple synthetic accesses to related structures allowing the preparation of a diverse set ...
