Environmental Science and Pollution Research - In this work, a novel composite, ball-milled biochar (BMB) encapsulated in calcium-alginate (CA) beads (CA-BMB), was synthesized as an alternative... 相似文献
A bibliometric analysis based on the Science Citation Index Expanded (SCI-EXPANDED) from the Web of Science was carried out to provide insights into research activities and tendencies of the global biodiesel from 1991 to 2015. The document type and language, characteristics of publication outputs, Web of Science categories, journals, countries, institutions, author keyword and most cited articles were emphasized. The results indicated that annual output of the related scientific articles increased steadily. The top six categories focus on different aspects of biodiesel research. Bioresource Technology and Fuel were the two most frequent journals in the field of biodiesel research. The USA took a leading position and had the highest h-index (108) out of 122 countries/territories, followed by China and Brazil. Finally, author keywords and most cited articles were analyzed, indicating that microalgae, Jatropha curcas, vegetable oil and waste cooking oil are the most general raw materials for biodiesel production. 相似文献
In this reported study, a renewable and eco-friendly blood meal-based (BM) bio-adhesive was developed for the plywood fabrication. Polyvinyl alcohol (PVA), sodium dodecyl sulphate (SDS), and triglycidylamine (TGA) were respectively employed as emulsifier, denaturant and crosslinking agent to modify the BM adhesive. Three-ply plywood was manufactured and its wet shear strength was tested. The solid content, residual rate, functional groups, thermal degradation behavior, and cross section micromorphology of the resulting adhesives were characterized in detail. The experimental results showed that PVA prevented the BM agglomeration, SDS unfolded the structure of protein and then TGA reacted with the exposed active groups in the BM protein molecules, forming a cross-linked structure. As a result, the thermal stability of the modified BM adhesive was improved and the cross section of the cured adhesive was more homogeneous, which enhanced the performance of the adhesive. Consequently, the wet shear strength of the plywood bonded by modified BM adhesive markedly increased by 388% to 1.27 MPa. Compared with soy bean meal-based adhesive, a higher protein content and hydrophobic amino acids content of BM are benefit for fabricating high performance bio-based adhesive, which rendered the BM adhesive practical for plywood industrial application. 相似文献
Electrophoresis release test (ERT) was established by our lab to observe the re-released hemoglobin (Hb) from red blood cells (RBCs) and whole blood. In this study, ERT was performed to study the effects of different plasma components including plasma, serum, albumin, globulin, fibrinogen, glucose, amino acid, vitamin, insulin, hormone, and inorganic ions on re-released Hb from RBC and whole blood samples during ERT. The results showed that plasma, serum, albumin, globulin, compound amino acid, essential amino acid, vitamin C, insulin, hormone, NaCl, KCl, CaCl2, and NaHCO3? decreased re-released RBC Hb; while glucose, vitamin B1, vitamin B2, and vitamin B12 elevated re-released RBC Hb. The differing effects of various plasma components on re-released Hb of RBC may play a significant role in blood conservation. 相似文献
With the increasing of high saline waste sludge production, the treatment and utilization of saline waste sludge attracted more and more attention. In this study, the biological hydrogen production from saline waste sludge after heating pretreatment was studied. The substrate metabolism process at different salinity condition was analyzed by the changes of soluble chemical oxygen demand (SCOD), carbohydrate and protein in extracellular polymeric substances (EPS), and dissolved organic matters (DOM). The excitation-emission matrix (EEM) with fluorescence regional integration (FRI) was also used to investigate the effect of salinity on EPS and DOM composition during hydrogen fermentation. The highest hydrogen yield of 23.6 mL H2/g VSS and hydrogen content of 77.6% were obtained at 0.0% salinity condition. The salinity could influence the hydrogen production and substrate metabolism of waste sludge.
