The microstructure of ternary L12-Al3(Sc1 yREy) intermetallics, where RE is one of the rare-earth elements selected from five light (La, Ce, Nd, Sm or Eu) or two heavy lanthanoids (Yb or Lu), was investigated as a function of RE concentration for 0.02 y 0.75. Alloys with light RE show two phases: L12-Al3(Sc,RE) and D019-Al3(RE,Sc) (or C11b-Al4(Eu,Sc)). Alloys with heavy RE exhibit a single L12A...

We developed a technique controlling contaminant Al3+ level using a combination of kinetics and thermodynamics at a pre-column derivatizing step in HPLC. The technique involves modifying a conventional HPLC of 8-quinolinol (Ox) complex with Al3+. The contaminant suppressing reagents, dihydroxyazobenzene (DHAB) and 1,2,3-trihydroxybenzene (pyrogallol) were added to the Ox and pH buffer solutions...

In Southeast Asia, swamp eels (Synbranchidae: Monopterus spp.) are a common source of human gnathostomiasis, a foodborne zoonosis caused by advanced third-stage larvae (AL3) of Gnathostoma spp. nematodes. Live Asian swamp eels are imported to US ethnic food markets, and wild populations exist in several states. To determine whether these eels are infected, we examined 47 eels from markets and 6...

Fe3+-immobilized mesoporous molecular sieves MCM-41 with particle size of ca. 600 nm and pore size of ca. 3 nm is synthesized and applied to selectively trap and separate phosphopeptides from tryptic digest of proteins. For the capture of phosphopeptides, typically 10 microL of tryptic digest solution was first diluted to 1 mL by solution of ACN/0.1% TFA (50:50, v/v) and incubated with 10 micro...

The biodegradable and non-toxic Bioflocculants have attracted considerable interest as alternative to non-biodegradable chemical flocculants. However, the cost of fermentation media for bioflocculant production low flocculation efficiency is a major challenge. In this study, we grow Bacillus spp isolated from sediment local clay pot on spoilt orange juice produce bioflocculant. culture supernat...

As an unnecessary element for human body, aluminum can cause a variety of diseases when ingested in excess, so it is great significance Al3+ detection. A new rhodamine probe with excellent photochromic properties based on Al3+- induced ring-opening mechanism the spirolactam was proposed. Upon binding Al3+, generated 1:1 P1-Al3+ complex, confirmed by Job’s plot titrations analysis. Could exhibit...

Mesoporous silica functionalized with a 2-hydroxy-naphthyl moiety has been synthesized and characterized by standard techniques like powder X-ray diffraction, N2 adsorption/desorption studies, transmission electron microscopy and spectral studies like FT-IR, UV-visible, fluorescence and 13C and 29Si solid state NMR. The functionalized silica material showed significant enhancement in its emissi...

Flower color not only determines the quality and commercial value of ornamental plants, but it also plays a vital role in ecological processes such as pollinator attraction. This study aimed to investigate relationship between flower cellular physicochemical factors Bletilla striata. The space values 21 samples were initially determined, followed by selection five with significant differences f...

A single injection of ferric nitrilotriacetate (Fe3+-NTA) caused a transitory increase in plasma immunoreactive insulin (IRI) and plasma immunoreactive glucagon (IRG) in rats. They reached maximum levels at 2 days after injection and returned to the normal range at 10 days. At 2 days after Fe3+-NTA injection, blood glucose level was normal but the glucose tolerance test (GTT) was impaired. Ther...
