We studied the growth of self-assembling monolayers of C(11)Eg(6)OMe on gold under aqueous conditions. With the help of polarisation modulation infrared reflection absorption spectroscopy (PMIRRAS) we monitored the evolution of characteristic absorption modes in the fingerprint region (1050-1500 cm(-1)) during the later stages of the growth of the SAM. We observed a change from rather amorphous...

This paper reports on a dynamic technique for measuring penetration of radiolabeled substances topically applied to the cornea! surface of anesthetized dogs. The agent was collected for analysis by perfusion of the aqueous chamber with isotonic saline as it traversed the corneal tissue. During collection of the perfusate over a period of 80 to 100 minutes, nearly physiologic conditions were mai...

We studied the growth of self-assembling monolayers of C11Eg6OMe on gold under aqueous conditions. With the help of polarisation modulation infrared reflection absorption spectroscopy (PMIRRAS) we monitored the evolution of characteristic absorption modes in the fingerprint region (1050–1500 cm ) during the later stages of the growth of the SAM. We observed a change from rather amorphous struct...

Nanostructured Mn oxide clusters supported on mesoporous silica KIT-6 efficiently evolve O(2) in aqueous solution under mild conditions.

An efficient gold-catalyzed amide synthesis from aldehydes and amines in aqueous medium under mild reaction conditions has been developed.

a simple, rapid and economic procedure was presented to remove lead(ii) from aqueous solution under the optimized conditions. it is based on the sorption of pb2+ ions from aqueous solutions onto limestone fines (ls), which is an inexpensive and widespread over the globe, followed by flotation with oleic acid (hol) surfactant. the different parameters (namely: solution ph, sorbent, surfactant an...

Seven aromatic aldehydes dissolved in aqueous acetic acid were oxidized in quantitative to good yields by sodium perborate in presence of traces of IrCl3. Conditions were obtained for getting the highest yields under the experimental conditions.

In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

Nanostructured RuO2 powders were synthesized via a hydrothermal method at 180 °C for 12 h using 1 and 2 M NaOH aqueous solutions. The structure of the obtained nanomaterials was investigated by powder X-ray diffraction (PXRD) technique. The morphology the obtained materials were studied by field emission scanning electron microscope (FESEM). The technique showed that with changing the reaction ...

Recent studies have shown that rates of bacterial dispersion in soils are controlled by hydration conditions that define size and connectivity of the retained aqueous phase. Despite the ecological implications of such constraints, microscale observations of this phenomenon remain scarce. Here, we quantified aqueous film characteristics and bacterial flagellated motility in response to systemati...
