The Study of Classification Analysis on Oil Exploration Research Trends and Digging Technology Based on Properties of Biochemical Materials (2012-2013)

The study aimed at analyzing the keywords of the oil exploration research papers abstracts in 2012 and 2013 and using the random forests model to make the classification analysis in order to find the importance and similarities of 2012 and 2013 research trends. The contribution of the study included the following two points. First, the study used the text mining method in order to explore the content of oil exploration research paper abstracts. Second, the study applied the AdaBoost classification analysis to explore the relationship of the keywords between the two years’ keywords.

Research of Surfactants Effect on Methane Hydrate Formation with Properties of Biochemical Materials

This paper deals with the effects of a surfactant additive on the formation of methane hydrate in water system with and without sodium dodecyl sulfate (SDS). The properties of sodium dodecyl sulfate are listed. The results manifested that the presence of SDS could not only accelerate the hydrate formation process, but also increase the partition coefficient of methane between hydrate and vapor drastically. The paper then describes our experimental observations of the hydrate formation from methane, to show how the hydrate formation behaviors are affected by the additives of chamber partially filled with a quiescent pool of water (pure water or an aqueous SDS solution) to compensate for the gas consumption due to the hydrate formation, thereby maintaining a constant pressure inside the chamber. The results revealed that the addition of SDS not only on the liquid-pool surface but also on the chamber walls above the level of the pool surface, leaving the bulk of the liquid pool free from hydrate crystals. An excessive addition of SDS beyond the solubility was found to cause a decrease in the rate of hydrate formation but an increase in the final level of the water-to-hydrate conversion.

Optimization of Formulations of 1% Abamectin Microcapsule Suspensions with Properties of Biochemical Materials

By orthogonal experiments, optimal formulation of 1% abamectin microcapsule suspensions was determined as follow: the proportion of abamectin microcapsule is 1%, NNO 5.0%, sodium dodecyl sulfate 3.0%, xanthan gum 0.3%, ethylene glycol 3%, and the remainder is water. The indicators of the formulation are all excellent: good dispersibility, suspension rate greater than 90%, cold storage and hot storage syneresis rates under 5%. The properties of biochemical materials were used in optimization. The optimal formulation provides an experimental basis for industrial production of abamectin microcapsule suspensions.

Research on Pollution Control Technologies of Oil Spill in River Water with Properties of Biochemical Materials

Abstract: In recent years, oil spill happens in river frequently, which has serious impact on the ecological environment and human health. So it is very important to conduct research on the pollution control technologies of oil spill in the river water. This paper analyzes the domestic and overseas existing oil spill pollution control technologies and puts forward the method combining oil recycling machine and oil dispersant to deal with the pollution caused by oil spill in Changqing Oilfield. Through the comparison, the turntable oil recycling machine and the SC-Y17 oil dispersant are finally selected. According to the experiment, we find that temperature has a great influence on the effect of oil dispersant and measures should be taken to improve the property to make it can adapt to the requirements of the low temperature environment.

Study on Kinetics and Biocompatibility Evaluation of Multiple Polymer Layer with Biochemical Material Properties in Drug-Eluting Stent

The Paclitaxel-eluting stents (PTX) with three-layered polymer coating were studied in this work. The PLGA (polylactic acid-co-glycolic acid) with 15 percent PEG (poly ethylene glycol) concentration in blend have been applied for preparing multiple layer drug carrier and fabricated on the surface of 316L stainless steel stents by ultrasonic atomization spraying method. The Paclitaxel was explored in doses: (~255μg) for single layer coated PTX (30 wt%), and (~275μg) for multiple layer coated PTX in accordance. Pre- and post-expansion surface morphologies of multiple layer stent were examined by scanning electron microscopy (SEM). The Paclitaxel release kinetics was studied by comparative method of release profiles of single layer PTX with 3-layered polymer coated PTX. The biocompatibility by hemolysis ratio and dynamic clotting time with platelet adhesion measurements also was investigated.

Selective Determination of Dopamine at Poly Sulfosalicylic Acid/Graphene Modified Electrode with Composite Properties of Biochemical Materials

A new type of poly (sulfosalicylic acid)/graphene modified electrode (PSA/GH/GCE) was fabricated by dispensing graphene (GH) on glassy carbon electrode (GCE) and then electro-polymerized sulfosalicylic acid onto GH/GCE with cyclic voltammtry method. It can be used with composite properties of biochemical materials for highly selective and sensitive detection of dopamine (DA) even in the presence of mass ascorbic acid (AA). The linear response range for DA was 70 nM to 700 μM, and the detection limit was 20 nM (S/N = 3).

Polymerized Structure and Improved Physical and Biochemical Material Properties of Carboxymethyl Dextran-Conjugated Collagen

Pepsin-solubilized collagen (PSC) was conjugated with carboxymethyl dextran (CMD) using cyanogen bromide to obtain a PSC-CMD film having improved physical properties, physiological properties, and cell affinity. The conjugation was confirmed by the loss of the alpha- and beta-subunit chains and the polymerized band on SDS-PAGE, and by a decrease in the isoelectric point to 3.2. PSC-CMD had a large polymerized structure with the 6 PSC and 228 CMD molecules. PSC-CMD was readily soluble in water, reconstructed a matrix with a less-ordered structure and a characteristic morphological shape, and lost platelet aggregation-inducing ability. The PSC-CMD film, cross-linked by ultraviolet irradiation, exhibited reduced solubility, moderate water vapor permeability, and increased flexibility. PSC-CMD coatings exhibited good cell attachment and growth for fibroblasts and vein endothrical cells.
