Through comparing the battery management system (BMS) in existence, it concludes that every BMS has its own features, such as, interface, communication, data hand method, and so on. There is no uniform standard in the...

In this research, carbon fiber (CF) was taken as reinforcing filler, nano calcium carbonate (CaCO3) was taken as toughener, maleic anhydride grafted polyethylene (PE-g-MAH) was taken as compatibilizer for high density polyethylene (HDPE) modification. Through orthogonal test, the influence of different amount of ingredient CF, CaCO3 and PE-g-MAH on the mechanical properties of the HDPE composites was researched. The optimal composition of the quaternary composites with the good toughness and high strength was obtained.

Bionics is a relatively young science, which was founded by the late 50's and 60's of the 19th Century. This branch of science is the study of natural organisms, materials and structures. These findings are trying to convert to technology. Life on earth has existed for more than 4 billion years. Throughout the organisms on the planet had to adapt to hostile conditions prevailing here. These adaptations brought most of the natural structures and materials to perfection. In this article it was studied a primitive animal, at first sight, that bother many people. The aim of the study is the housefly. How this little annoying insects could inspired us? Housefly is a very good flier, which can very well plough through the vertical smooth glass surface and has a very short reaction time on the stimulus. By scanning electron microscope, we entered into the secret of how to plough through the smooth vertical walls. We were inspired by the structure located at the end of feet of housefly. After a detailed study it was made a model of the feet of housefly in a macro scale. This model was subsequently tested for the functionality in a macro scale.
The focus of this technical manuscript is a record of the specific role of microstructure and test specimen orientation on cyclic stress response, cyclic strain resistance, and cyclic stress versus strain response, de...

Thermally responsive hydrogels have drawn significant research attention recently because of their simple use as drug carrier at human body temperature. Here we design a hybrid hydrogel that incorporates a hydrophilic polymer, polyethyleneimine (PEI), into the thermally responsive hydrogel poly( N ‐isopropylacrylamide) (PNIPAm), as a general drug carrier model for controlled drug release. In this work, on one hand, PEI modifies the structure and the size of the pores in the PNIPAm hydrogel. On the other hand, PEI plays an important role in tuning the water content in the hydrogel and controls the water release rate of the hydrogel below the lower critical solution temperature (LCST), resulting in a tunable release rate of the drugs at human body temperature (37 °C). Different release rates are shown as different amounts of PEI are incorporated. PEI controls the release rate, dependent on the charge characteristics of the drugs. The hydrogel blends described in this work extend the concept of a general drug carrier for loading both positively and negatively charged drugs, as well as the controlled release effect.

Measurements of physical properties, including transport and magnetic properties, specific heat, and thermal conductivity, have been performed on high-quality samples of LaNiO3 and LaCuO3 synthesized under high pressure. Some measurements, such as thermoelectric power and magnetic susceptibility, have been made under high pressure. The availability of a complete set of data enables a side-by-side comparison between these two narrowband systems. We have demonstrated unambiguously the mass enhancement due to electron-electron correlations in both systems relative to the recent density functional theory results. Correlations in these narrowband systems also enhance the magnetic susceptibility. Ferromagnetic spin fluctuations give rise to a strong Stoner enhancement in the magnetic susceptibility in the quarter-filled LaNiO3. Although we are able to tune the bandwidth by either chemical substitutions or by applying hydrostatic pressure on LaNiO3, the Stoner enhancement does not lead to the Stoner instability.
The temperature distribution in the vicinity of the laser used in direct metal deposition (DMD) plays a critical role in determining the final microstructure and mechanical properties of the deposit and the heat-affec...
