Low‐molecular‐weight (LMW) organic acids exist widely in soils and have been implicated in many soil processes. In the present paper, the effect of the anions of four LMW organic acids on the adsorption of potassium (K) by two variable charge soils was investigated. The results showed that the presence of organic anio…

Clay that contains kaolinite has been used extensively as a raw material for manufacturing of bricks and china at 900-1100 degrees C. This study used clay to stabilize the contaminant chromium(VI) [Cr(VI)] through a heating process at 500-1100 degrees C. X-ray absorption spectroscopic results indicated that the 500-90…

The effects of the fabrication process on the current–voltage ( I – V ) characteristics of carbon nanotube field effect transistors (CNT-FETs) were studied in detail. A large hysteresis observed in the I – V characteristics of the CNT-FETs having no passivation film became small by passivating the device surface with…

The coadsorption of molecular nitrogen and oxygen on small cationic silver clusters in the gas phase is experimentally studied. The presence of oxygen enhances the adsorption probabilities of N2. This indicates a partial charge transfer out of the finite free electron reservoir of the small silver particles into the c…

We present sidewall functionalization of carbon nanotubes via various dissolving metal reduction methods. Carbanion complexes of lithium were prepared in liquid ammonia and THF and reacted with a series of alkyl and aryl halogenides, as well as methanol resulting in the formations of alkylated, arylated, and hydrogena…

A window-type environmental cell that can be used over the temperature range from room temperature to approximately 1000 K was improved by incorporating a new window material that increases resolution and contrast in high voltage electron microscopy. With this improvement, the resolution was a few nanometers and the m…

When Pb(Mg 1/2 Nb 2/3 )O 3 –35PbTiO 3 (mol%) (PMN–35PT) is sintered at 1200°C after packing in PbZrO 3 powder, the grains show normal growth with time invariant normalized grain size distributions. If 0.5 wt% MgO is added to PMN–35PT, abnormal grain growth occurs with the large abnormal grains developing nearly cubic…

Ti‐6Al‐4V alloy has attracted increasing applications as a metallic biomaterial in recent years thanks to its good corrosion resistance and biocompatibility. However, the poor corrosion‐wear resistance of the alloy is thus a major concern to potential users. In this paper, the electrochemical noise technique is used a…

The iron sulfate FeOHSO 4 studied was obtained as a dehydration product of metahohmannite Fe 2 (H 2 O) 4 [O(SO 4 ) 2 ] during a synchrotron real-time powder diffraction experiment. As quoted in the literature, FeOHSO 4 has iron atoms octahedrally coordinated with two hydroxyl groups and four sulfate O atoms, while eac…

Abstract A series of azobenzene derivatives containing glycine, l-alanine, l-valine, l-leucine, and l-isoleucine were synthesized and their gelation properties were examined. Although the azobenzene derivatives containing glycine, l-alanine, and l-leucine exhibited very low gelation abilities, other compounds of l-iso…
