Moreover,the green fluorescent emissions centering at 522 and 546nm and the red fluorescent emi-ssion at 658nm were obtained under the laser diode excitation at 977 nm,which respectively corresponded to the transitions 2H11/2→4I15/ 2,4S3/2→4I15/2 and 4F9/2→4I15/2 of Er3+.
rMargatoxin (0.1 nmol/L and 10 nmol/L) markedly reduced the contents of TC, FC and CE in macrophages and the ratios of CE/TC decreased to (42.8±11.6)% and (22.6±8.0)%, respectively (n=7, P<0.05). Meanwhile, the red lipid granules deposited in the cytoplasm of macrophages also decreased.
In the0.6mol/LHCl medium,the DCHPF reacts with tungsten(Ⅵ)from a red complex with stoichiometric ratio of2∶1,a maximum absorption at536nm and an apparent molar absorptivity of1.28×10 5 L·mol -1 ·cm -1 .Beer's lawwas obeyed in the range of0～0.4mg/L tungsten(Ⅵ).
In the presence of Tween-80,Pd(Ⅱ)reacted with TNBDAA to form a red complex with molor ratio of 1∶1 in a medium of pH8.0-9.5.Its apparent molor absorptivity was 1.0×105 L·mol-1·cm-1 at the maximum absorption of 553nm.
Compared with the basal diet group,meat red color degree in group of methionine selenium and yeast selenium were increased 20.84%(P<0.01), 10.76%(P<0.05),drip loss were decreased 21.32%(P<0.01) and 14.23%(P<0.05) respectively,and there was significant differences between organic Se and inorganic Se.
The Fundamental Experiments of Red Tide Chemical Forecast
Many food algae and red tide algae were cultivated in the f/2 medium, and the nitric oxide (NO) concentration of the medium and the cell density were determined.
The results indicate that red tide algae are far more sensitive to NO than are food algae.
The fundamental experimental outcome above may provide a new clue for red tide chemical forecast by inspecting the NO change.
The copolyimides were characterized by Infra-red (IR), Nuclear Magnetic Resonance (NMR), Gel Permeation Chromatography (GPC), Ultraviolet Visual (UV-Vis), Thermogravimetic Analysis (TGA) and Dynamic Mechanical Analysis (DMA).
Fourier transform infrared spectroscopy (FTIR) results displayed the red shifts of absorption bands of amide II and amide III (9 and 5 cm-1, respectively), which were related to the strong chemical interaction between HA and fibroin.
Production of agar and agarose from the red algaAhnfeltia tobuchiensis
A simple and inexpensive procedure of agar and agarose production from the red algaAhnfeltia tobuchiensis was developed, which needs no additional Chromatographic purification.
Properties of chitinolytic enzymes from the hepatopancreas of the red king crab (Paralithodes camtschaticus)
Our study confirms the presence of chitinolytic, chitosanolytic, and deacetylase activities in the hepatopancreas of the red king crab, related to the specific diet of this species.
A red shift was found in the spectrum of modified TiO2 films.
(Dend FP) is characterized by an irreversible lightdependent conversion to a red-emitting form.
Native cytochrome c (Cyt c) has a fluorescence maximum at 335 nm, where as the TCA-induced state of Cyt c has a red shift of 7 nm with enhanced fluorescence intensity.
It is established that the addition of niobium oxide Nb2O5 to lead phosphate glasses brings about a red shift of the UV transmission edge and a change in the crystallization ability of the glasses.
Both standard indifferent (a rhythmically flashing light and an acoustic tone) and functionally significant (a moving contrasting black-and-white strip, a red spot, the mother's voice, music, etc.) afferent stimuli were used.
After the decoloration of the red color of methyl orange, the residual bromine is titrated iodometrically to a starch endpoint.
The argillic component (clasts of chocolate clays) predominates in the clastic material and imparts the brownish red color to sands and sandstones of the Bugrovaya sequence.
Under low O2 conditions, PG activity was low and the fruits remained firm and green throughout storage, whereas, during storage in the air, PG activity increased and the fruits softened and developed their characteristic red color.
Vanillin reacted most rapidly to produce a red color.
But the relative intensity of red PL (620 nm) was much greater than that of green PL (590 nm) of the same sample, that's to say, the red color was the main luminescence.
