Sorption of Eu(III) on Attapulgite Studied by Batch, XPS and EXAFS Techniques.
The effects of pH, ionic strength and temperature on sorption of Eu(III) on attapulgite were investigated in the presence and absence of fulvic acid (FA) and humic acid (HA). The results indicated that the sorption of Eu(III) on attapulgite was strongly dependent on pH and ionic strength, and independent of temperature. In the presence of FA/HA, Eu(III) sorption was enhanced at pH 7. The X-ray photoelectron spectroscopy (XPS) analysis suggested that the sorption of Eu(III) might be expressed as β‘X3Eu0 β‘SwOHEu3+ and β‘SOEu-OOC-/HA in the ternary Eu/HA/attapulgite system. The extended X-ray absorption fine structure (EXAFS) analysis of Eu-HA complexes indicated that the distances of d(Eu-O) decreased from 2.451 to 2.360 Γ
with increasing pH from 1.76 to 9.50, whereas the coordination number (N) decreased from ~9.94 to ~8.56. Different complexation species were also found for the different addition sequences of HA and Eu(III) to attapulgite suspension. The results are important to understand the influence of humic substances on Eu(III) behavior in the natural environment
Analysis of Fracture Behavior of Thin Polycrystalline Diamond Films
The effect of the substrate temperature and CHβ
concentrations on the fracture behavior of thin
polycrystalline diamond films was systematically
investigated by X-ray diffraction and scanning
electron microscopy. The results show that the
fracture behavior of thin polycrystalline diamond
films synthesized by direct current plasma jet
chemical vapor deposition is closely related to
the substrate temperature and CHβ concentrations.
A high substrate temperature, due to difference
in the thermal expansion coefficients of the
substrate and the diamond film, causes thin
polycrystalline diamond films to generate high
residual stresses, which usually exceed fracture
strength of thin diamond film and even that of diamond.
The fracture toughness is found to drop
with the increasing ratio of CHβ concentration.
In case of high CHβ concentrations, various defects
and impurities, such as cracks, microscopic
holes, graphite, and amorphous carbon
were observed in the films. Thus, the substrate
temperature and CHβ concentrations should be
strictly controlled within an appropriate
range.Π‘ ΠΏΠΎΠΌΠΎΡΡΡ ΡΠ΅Π½ΡΠ³Π΅Π½ΠΎΠ²ΡΠΊΠΎΠΉ Π΄ΠΈΡΡΠ°ΠΊΡΠΈΠΈ ΠΈ ΡΠΊΠ°Π½ΠΈΡΡΡΡΠ΅ΠΉ ΡΠ»Π΅ΠΊΡΡΠΎΠ½Π½ΠΎΠΉ ΠΌΠΈΠΊΡΠΎΡΠΊΠΎΠΏΠΈΠΈ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΎ Π²Π»ΠΈΡΠ½ΠΈΠ΅ ΡΠ΅ΠΌΠΏΠ΅ΡΠ°ΡΡΡΡ ΠΏΠΎΠ΄Π»ΠΎΠΆΠΊΠΈ ΠΈ ΠΏΠΎΠΊΠ°Π·Π°ΡΠ΅Π»Ρ ΠΊΠΎΠ½ΡΠ΅Π½ΡΡΠ°ΡΠΈΠΈ CHβ Π½Π° ΠΏΠΎΠ²Π΅Π΄Π΅Π½ΠΈΠ΅ ΡΠΎΠ½ΠΊΠΈΡ

Simple Memristive SPICE Macro-Models and Reconfigurability in Filter and Antenna
Simple current- and voltage-controlled memristive circuit macro-models using SPICE are proposed to capture the nonlinear hysteresis loop behaviors in this paper. Different current-voltage characteristics are investigated by applying sinusoidal-wave, triangular-wave and square-wave source, respectively. Furthermore, using finite-difference time-domain (FDTD) emulator incorporated with a SPICE circuit solver, the current- or voltage-controlled memristive SPICE model is embedded into a planar microwave bandstop filter (BSF) and an ultra-wideband (UWB) monopole antenna, which connects two ends of the half-wavelength open-loop resonator and two sides of the U-slot in the radiating patch, respectively. The reconfigurability of the BSF and antenna notched band can be achieved by switching the states of the memristor
Study on Thermal Stress of Honeycomb Ceramic Regenerators with Different Parameters
In thermal flow-reversal reactor operations, honeycomb
ceramic regenerators are exposed to
thermal shock load. In this study, numerical simulations
of the temperature and thermal stress
distributions of honeycomb ceramic regenerators
are carried out using the CFX software.
Temperature variations with time are calculated
first for honeycomb ceramic regenerators with
holes of different shapes. Then, thermal stress
distributions of regenerators are analyzed with
different structural and operational parameters.
The analyses show that the thermal stress of honeycomb
ceramic regenerator depends on the
shape of holes, porosity and wall thicknesses.
This study provides a theoretical basis for optimization
of honeycomb ceramic regenerators.ΠΡΠΈ ΡΠ°Π±ΠΎΡΠ΅ ΡΠ΄Π΅ΡΠ½ΠΎΠ³ΠΎ ΡΠ΅Π²Π΅ΡΡ-ΠΏΠΎΡΠΎΡΠ½ΠΎΠ³ΠΎ ΡΠ΅Π°ΠΊΡΠΎΡΠ° ΠΊΠ΅ΡΠ°ΠΌΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΡΠΎΡΠΎΠ²ΡΠ΅ ΡΠ΅Π³Π΅Π½Π΅ΡΠ°ΡΠΎΡΡ ΠΏΠΎΠ΄Π²Π΅ΡΠ³Π°ΡΡΡΡ Π΄Π΅ΠΉΡΡΠ²ΠΈΡ ΡΠ΅ΡΠΌΠΎΡΠ΄Π°ΡΠ½ΠΎΠΉ Π½Π°Π³ΡΡΠ·ΠΊΠΈ. Π‘ ΠΏΠΎΠΌΠΎΡΡΡ ΠΏΡΠΎΠ³ΡΠ°ΠΌΠΌΠ½ΠΎΠ³ΠΎ ΠΎΠ±Π΅ΡΠΏΠ΅ΡΠ΅Π½ΠΈΡ CFX

Effect of alirocumab on major adverse cardiovascular events according to renal function in patients with a recent acute coronary syndrome: Prespecified analysis from the ODYSSEY OUTCOMES randomized clinical trial
Aims Statins reduce cardiovascular risk in patients with acute coronary syndrome (ACS) and normal-to-moderately impaired renal function. It is not known whether proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors provide similar benefit across a range of renal function. We determined whether effects of the PCSK9 inhibitor alirocumab to reduce cardiovascular events and death after ACS are influenced by renal function. ................................................................................................................................................................................................... Methods ODYSSEY OUTCOMES compared alirocumab with placebo in patients with recent ACS and dyslipidaemia despite and results intensive statin treatment. Estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m was exclusionary. In 18 918 patients, baseline eGFR was 82.8 Β± 17.6 mL/min/1.73 m , and low-density lipoprotein cholesterol (LDL-C) was 92 Β± 31 mg/dL. At 36 months, alirocumab decreased LDL-C by 48.5% vs. placebo but did not affect eGFR (P = 0.65). Overall, alirocumab reduced risk of the primary outcome (coronary heart disease death, non-fatal myocardial infarction, ischaemic stroke, or unstable angina requiring hospitalization) with fewer deaths. There was no interaction between continuous eGFR and treatment on the primary outcome or death (P = 0.14 and 0.59, respectively). Alirocumab reduced primary outcomes in patients with eGFR >_90 mL/min/1.73 m (n = 7470; hazard ratio 0.784, 95% confidence interval 0.670β0.919; P = 0.003) and 60 to <90 (n = 9326; 0.833, 0.731β0.949; P = 0.006), but not in those with eGFR < 60 (n = 2122; 0.974, 0.805β1.178; P = 0.784). Adverse events other than local injection-site reactions were similar in both groups across all categories of eGFR. ................................................................................................................................................................................................... Conclusions In patients with recent ACS, alirocumab was associated with fewer cardiovascular events and deaths across the range of renal function studied, with larger relative risk reductions in those with eGFR > 60 mL/min/1.73 m 2 2 2 2The trial was funded by Sanofi and Regeneron Pharmaceuticals, Inc
Scaling Behavior of Anomalous Hall Effect and Longitudinal Nonlinear Response in High-Tc Superconductors
Based on existing theoretical model and by considering our longitudinal
nonlinear response function, we derive a nonliear equation in which the mixed
state Hall resistivity can be expressed as an analytical function of magnetic
field, temperature and applied current. This equation enables one to compare
quantitatively the experimental data with theoretical model. We also find some
new scaling relations of the temperature and field dependency of Hall
resistivity. The comparison between our theoretical curves and experimental
data shows a fair agreement.Comment: 4 pages, 3 figure
