A novel strategy for the construction of silk fibroin–SiO composite aerogel with enhanced mechanical

《化学科学与工程前沿(英文)》 2023年 第17卷 第3期   页码 288-297 doi: 10.1007/s11705-022-2222-7

摘要: The practical application of silica aerogels is an enormous challenge due to the difficulties in improving both mechanical property and thermal insulation performance. In this work, silk fibroin was used as scaffold to improve the mechanical property and thermal insulation performance of silica aerogels. The ungelled SiO2 precursor solution was impregnated into silk fibroin to prepare silk fibroin–SiO2 composite aerogels via sol−gel method followed by freeze-drying. By virtue of the interfacial hydrogen-bonding interactions and chemical reactions between silk fibroin and silica nanoparticles, SiO2 was well-dispersed in the silk fibroin aerogel and composite aerogels exhibited enhanced mechanical property. By increasing the loading of silk fibroin from 15 wt % to 21 wt %, the maximum compressive stress was enhanced from 0.266 to 0.508 MPa when the strain reached 50%. The thermal insulation performance of the composite aerogels was improved compared with pure silica aerogel, as evidenced that the thermal conductivity was decreased from 0.0668 to 0.0341 W∙m‒1∙K‒1. Moreover, the composite aerogels exhibited better hydrophobicity and fire retardancy compared to pure silica aerogel. Our work provides a novel approach to preparing silk fibroin–SiO2 composite aerogels with enhanced mechanical property and thermal insulation performance, which has potential application as thermal insulation material.

Durable and recyclable BiOBr/silk fibroin-cellulose acetate composite film for efficient photodegradation

《化学科学与工程前沿(英文)》 2023年 第17卷 第11期   页码 1765-1775 doi: 10.1007/s11705-023-2323-y

摘要: A stable and recyclable of BiOBr/silk fibroin-cellulose acetate composite film was prepared by blending-wet phase transformation and in situ precipitate technology. The cellulose acetate film modified by silk fibroin formed a finger-shaped porous structure, which provided a large space for the uniform growth of BiOBr nanosheets and facilitated the shuttle flow of dyes in film. The morphology, phase structure, and optical properties of the composite films were characterized using various techniques, and their photocatalytic performance for dye wastewater was evaluated under visible light irradiation. Results showed that the BiOBr/SF-CA composite film exhibited efficient photocatalytic activity with 99.9% of rhodamine B degradation rate. Moreover, the composite film maintained high catalytic stability because Bi as the active species deposited on the film showed almost no loss. Finally, the possible photocatalytic mechanisms in the BiOBr/SF-CA composite film were speculated through radical-trapping experiments and electron spin resonance testing.

Construction of sustainable, colored and multifunctional protein silk fabric using biomass riboflavin

《化学科学与工程前沿(英文)》 2023年 第17卷 第8期   页码 1131-1139 doi: 10.1007/s11705-023-2321-0

摘要: Riboflavin sodium phosphate has been confirmed as a promising biomass product derived from natural plants. In this paper, a novel method of dyeing and multifunctional modification of silk fabric by impregnation with riboflavin sodium phosphate was proposed, such that protein silk fabric can be endowed with bright yellow color and multi-functionality. The results of this paper confirmed that the pH and concentration of riboflavin sodium phosphate solution are critical factors for dyeing and multifunctional modification. Attractively, the photochromic performance was one of the most distinctive features of the modified silk fabric, and the dyed silk fabric turned into fluorescent green from original yellow under 365 nm ultraviolet lamp. Furthermore, the modified silk fabric exhibited good antibacterial properties with a high inhibition rate of 92% for Escherichia coli. Besides, the flame retardancy of silk fabric was significantly improved after modification. The damaged length of modified silk fabric with 40% owf riboflavin sodium phosphate was lower than 10.4 cm and passed the B1 classification. As revealed by the result of this paper, riboflavin sodium phosphate is sufficiently effective in serving as an eco-friendly multifunctional agent for strengthening the add-value of silk textiles.

摘要: This work synthesizes the structures of the foot-operated silk-reeling mechanism, which was vaguely depicted in many literatures in ancient China. Based on the analysis of the mechanism, the structural characteristics and design constraints of the mechanism with indeterminate links and joints are concluded. Then, according to the concepts of generalization and specialization subject to the concluded design constraints, all feasible structures of the mechanism that met the technological standards of the subject’s time period are reconstructed. This reconstruction process provides a logical foundation to better understanding, clarification, and suggestions for the issue of ancient mechanical drawings with indeterminate links and joints.

Determination of energy dissipation of a spider silk structure under impulsive loading

摘要:

Various researches and studies have demonstrated that spider silk is much stronger and more deformable than a steel string of the same diameter from a mechanical approach. These excellent properties have caused many scientific disciplines to get involved, such as bio-mechanics, bio-materials and bio-mimetics, in order to create a material of similar properties and characteristics. It should be noted that the researches and studies have been oriented mainly as a quasi-static model. For this research, the analysis has taken a dynamic approach and determined the dissipation energy of a structure which is made of spider silk “Dragline” and produced by the Argiope-Argentata spider, through an analytical-experimental way, when being subjected to impulsive loading. Both experimental and analytical results, the latter obtained by using adjusted models, have given high levels of dissipation energy during the first cycle of vibration, which are consistent with the values suggested by other authors.

摘要: Infrastructure facilitates the movement of people, the production and distribution of goods and services, and underpins development. Infrastructure is expensive and long-lasting, and needs long-term policy, planning and management, in terms of design, construction, operation and maintenance. Infrastructure relates particularly to engineering and technology. All technological change brings economic, social, cultural and environmental change, planned and unpredicted. Mega levels of technology bring mega levels of change, effects and impacts. Mega infrastructure such as the Silk Road Economic Belt and 21st Century Maritime Silk Road, the “One Belt, One Road” (OBOR) initiative, announced by President Xi Jinping in 2013, will require equally mega policy, planning and management. This paper will discuss policy, planning and management issues relating to mega infrastructure and the OBOR initiative, with particular reference to energy, communications, transportation, health, emergency preparedness and response, and less predictable areas of change, for example in disease prevention and control, within the overall need for economic, environmental and ecological sustainability. The paper will discuss associated needs for education, training and capacity building in engineering. The paper will also refer to lessons learnt from the original Silk Road in the context of the development of civilizations and intercultural dialogue through the transfer of goods, services, technologies, ideas, knowledge, customs, cultures and philosophies, less predictable and unwanted transfers, for example of disease, and the need for awareness, policy, planning and management of such wider issues.

摘要:

21世纪海上丝绸之路战略支点是指承载我国与沿线国家经贸、科技、文化合作功能的空间区域。近年来,我国与沿线国家在经贸合作园区、交通基础设施建设等方面开展了广泛合作,取得了良好效果,但也存在顶层设计不清晰、空间布局不合理、合作方式较单一、合作层次不丰富等问题。本研究以围绕“五通”加强战略支点建设为研究目标,在我国对外贸易数据分析为基础,利用层次分析法和德尔菲法,提出了战略支点建设的重点区域和建设模式,并从推进经贸合作区建设、加强科技文化交流、深化地区与行业合作等方面提出了政策建议。
