Superconducting properties and non-isothermal crystallization kinetics of a BiSrCaCuO (Bi2212) superconductor prepared by the Pechini sol-gel method.

Bi2212 superconductors with crystallization treatments at different temperatures were prepared by the Pechini sol-gel method, and their structural, thermal and transport properties were investigated. The X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) results revealed the high purity and sheet crystal structures of the prepared samples. The non-isothermal crystallization kinetics and process of the Bi2212 superconductor were characterized and analyzed by differential scanning calorimetry (DSC) and Jeziorny and Mo methods, respectively.

Study on synthesis and application of tetrabasic lead sulfate as the positive active material additive for lead-acid batteries.

Tetrabasic lead sulfate (4BS) was used as a positive active material additive for lead-acid batteries, which affirmatively affected the performance of the battery. Herein, tetrabasic lead sulfate was synthesized from scrap lead paste that was formed through the production process of the lead-acid batteries. This solves the disposing problem of the scrap lead paste that is challenging in the production of the lead-acid batteries.

Numerical simulation on the generation of ultrasound and formation of water fog in the ultrasonic gas atomizer.

The water spraying itself is a dynamic course, and it is affected not only by structural style of ultrasonic gas atomizer and compressed air pressure, but also by movement of compressed air flow and so on in the atomizer. Here, the main principle of fine droplet formation in the ultrasonic gas atomizer is that the liquid sheet is disrupted into droplets by the energy of the high velocity air. If the ultrasonic energy is supplied, finer droplets with high sphericity and uniform size distribution can be achieved.

A comparative study on influences of static electric field and power frequency electric field on cognition in mice.

Recently, electromagnetic fields around ultra-high voltage transmission lines have received considerable attentions for their potential biological effects. This study aimed to investigate the effects of static electric field (SEF) and power frequency electric field (PFEF) on cognition. Mice were exposed to SEF and PFEF with the same strength (35 kV/m) for 49 days, respectively.

Terminal Deoxynucleotidyl Transferase and T7 Exonuclease-Aided Amplification Strategy for Ultrasensitive Detection of Uracil-DNA Glycosylase.

As one of the key initiators of the base excision repair process, uracil-DNA glycosylase (UDG) plays an important role in maintaining genomic integrity. It has been found that aberrant expression of UDG is associated with a variety of diseases. Thus, accurate and sensitive detection of UDG activity is of critical significance for biomedical research and early clinical diagnosis.

A novel lung cancer detection algorithm for CADs based on SSP and Level Set.

The fuzzy degree of lung nodule boundary is the most important cue to judge the lung cancer in CT images. Based on this feature, the paper proposes a novel lung cancer detection method for CT images based on the super-pixels and the level set segmentation methods. In the proposed methods, the super-pixels method is used to segment the lung region and the suspected lung cancer lesion region in the CT image.
