In this study, MnO² with different nanostructures (nanorods, nanospheres, nanoflowers, nanolychee) were obtained using a facile chemical method by adding different amounts of sulfuric acid for application in supercapacitors. Structure, morphology and composition were examined by X-ray diffractometer, Brunauer-Emmett-Teller, Fourier transform infrared, etc. Electrochemistry performances were tested by Autolab and LANHE CT2001A test system. Results indicated that the nanoflower MnO² (F-MnO²) exhibited largest specific surface area, which was 83.17 m² g-1. Electrode materials were tested in different electrolytes, including 6.0 M KOH, 1.0 M LiNO₃ and 1.0 M LiOH. The F-MnO² electrode material displayed the best electrochemical properties, and its specific capacitance was 171 F g-1 at 1 A g-1. Moreover, F-MnO² electrode material showed splendid cycling durability was 130.9% of original value after 1000 cycles. These results demonstrated that the F-MnO² electrode material should be a promising candidate for application in supercapacitors.This study aims to examine the mechanical behavior of disintegrated carbonaceous mudstone modified with nanosilica and cement (DCMNC). Many DCMNC specimens with various nanosilica contents were prepared. The X-ray diffraction (XRD) analyses and scanning electron microscopy (SEM) observations were performed on some of the specimens. Afterwards, triaxial tests were carried out on the remaining specimens to determine the mechanical behavior of DCMNC. The results showed that the cohesion exhibited a positive correlation with nanosilica content while the angle of internal friction presented a negative correlation with nanosilica content. N-Acetyl-DL-methionine in vitro The peak deviatoric stress, residual deviatoric stress and brittle modulus of DCMNC showed an increase followed by a decrease as nanosilica content varied from 0 to 8%, and all of them reached corresponding maximums at a nanosilica content of 2%. Thus, 2% was considered to be the optimum nanosilica content. The modification mechanism of DCMNC could be explained by the pozzolanic reaction related to nanosilica and the filling effect of nanosilica.We performed MD simulations to examine dimethyl sulfoxide (DMSO) nanocluster structures in NaCl aqueous solution with different concentrations (0.45 g/100 mL, 0.9 g/100 mL, 1.8 g/100 mL, 2.7 g/100 mL, and 3.6 g/100 mL). Results showed that interaction between Na+ and DMSO at the first solvation shells was weakened due to acceleration rotational influence of ion driven by NaCl concentration. We investigated the tetrahedral order parameter and average H-B number of water molecules. These results indicated that NaCl influenced the solvation structure of water cluster, but that of DMSO was not affected by NaCl. We also found that Na+ was prior solvated by water solution in these mixture systems, and Cl- only existed in the water cluster in our simulation systems. Consequently, we herein proposed a decentralized model that depicts microphysical structure images of DMSO in NaCl aqueous solution systems.This paper presents a novel symmetric current-conveyor transimpedance amplifier (SCC-TIA) implemented in a 0.13-μm CMOS technology for the applications of LiDAR systems, where a modifiedcascode configuration is newly proposed for input current buffer to deliver the photo-currents to the following voltage-mode inverter TIA without signal loss. Measured results of the proposed SCC-TIA demonstrate 69-dBΩ transimpedance gain, 410-MHz bandwidth, 13-pA/sqrt (Hz) average noise current spectral density, and 20-mW power dissipation from a single 1.2-V supply. Chip core occupies the area of 280×130 μm².We computed molecular properties of a long-tail amidine surfactant (N’-dodecyl-N,N-dimethylacetamidinium bicarbonate, DDAB) through quantum mechanics (QM) method. We then used molecular dynamics (MD) computations to obtain the properties of DDAB when displaced from the center to the boundary surface. The QM calculation results indicated that the mono-dentate type of bindings between polar head group and HCO-₃ ion was more likely to be adopted. The MD results indicated that the HCO-₃ ions could pass the energy barrier surrounding the head groups to form stable ion pairs. Meanwhile, the surfactant molecules aggregated very quickly, and absorbed in a direction pointed from the bulk center to the boundary. These results indicated that hydrophobic correlations of alkyl chains are the driving force for boundary adsorption of DDAB.To improve corrosion performance of coatings on AZ31B magnesium alloy, the nano-CeO² additives were included in Na²SiO³ based electrolyte during process of pulse micro arc oxidation (MAO). The MAO-CeO² coating was successfully prepared to characterize its structure, micro morphology and composition. The XRD results indicated that MAO-CeO² coatings were consisted of Mg²SiO⁴, MgSiO³, MgF² and CeO². The intensity of CeO² peaks increases with increasing nano-CeO² particles in electrolyte. The number of cracks on MAO-CeO² coatings exhibited a V-shaped trend with increase in nano-CeO² content. Meanwhile, the influence of nano-CeO² on corrosion behavior of MAO-CeO² coatings is investigated by salt spray test and electrochemical measurement. The corrosion current density of coatings presented same trend and corrosion potential is further studied. The MAO-CeO² coatings formed in electrolyte with 10 g/L nano-CeO² showed best corrosion performance which has the lowest corrosion current density of 0.58 nA/cm² and the highest corrosion potential of – 1269 mVSCE.A simplified OLED SPICE model with two resistors and two capacitors that have constant or voltagedependent (VD) values is proposed. Our model includes physical characteristics such as voltage and frequency dependency and agrees well with measurements. In this paper, we analyze the OLED frequency dependency effects and RC delay properties by controlling model parameters for DC, AC, and transient conditions. Importantly, we found that a model with constant parameters is simple and is accurate enough. Based on our simulation results, we suggest a new guideline for an OLED SPICE circuit model and simulation target.
