Recent Innovations in Chemical Engineering (Formerly Recent Patents on Chemical Engineering) - Volume 9, Issue 1, 2016

Background: In the energy-storage systems, supercapacitors have a wide range of applications in such as consumer electronics and hybrid electric vehicles because they are able to store and deliver energy at high rate. Nanocarbons and their composites have large specific surface area, high electronic conductivity and excellent chemical stability, promising for the electrode materials of supercapacitors. Methods: We briefly re Read More

Background: According to the Guinness Book of Records, the earliest of allknown English patents for an invention was granted by King Henry VI in 1449 to Flemishborn John Utynam for making stained glass. The second patent was approved by King Edward VI and granted to Henry Smyth in 1552 for making Normandy glass. Objective: To show that most of the first published patents were related to the manufacture of glass o Read More

Background: As the major product in international tea market, black tea accounted 75% of global tea trade in the world. China is the headstream of black tea as well as the major production country in the world. In recent years, the trend in consuming black tea has been rising, which gives big opportunity for the fast promotion and effective development in the black tea industry. Objective: To make a comparative study on the q Read More

Background: Zeolites have been widely applied in adsorption, separation, sensors and catalysis fields due to their uniform micropore structures, high surface areas and many other properties. However, their small micropores frequently cause molecular diffusion limitations, which impede their applications in many chemical reactions. Objective: To synthesize mesoporous zeolites via a hard templating route. Methods: Silicali Read More

NiS/reduced graphene oxide nanocomposites were prepared by a hydrothermal method. Electron microscope observation revealed that the materials were of thin sheet-like structure and X-ray diffraction indicated the NiS of high-purity on the graphene nanosheets. Nitrogen adsorption on the samples at 77 K revealed the porous properties. Such materials were pseudo-active, exhibiting high specific capacitance of 978 F g- Read More

Objective: This work aims to use slow features extraction of time-varying signals to solve the unfavorable influences of traditional principal component analysis (PCA) method on feature extraction in Tennessee Eastman (TE) process. Methods: Slow feature principal component analysis (SFPCA) method can obtain the slow features information of the observed data while considering variance maximization. The monitoring Read More
