Eco-Sustainable Silk Fibroin/Pomegranate Peel Extract Film as an Innovative Green Material for Skin Repair

Skin disorders are widespread around the world, affecting people of all ages, and oxidative stress represents one of the main causes of alteration in the normal physiological parameters of skin cells. In this work, we combined a natural protein, fibroin, with antioxidant compounds extracted in water from pomegranate waste. We demonstrate the effective and facile fabrication of bioactive and eco-sustainable films of potential interest for skin repair. The blended films are visually transparent (around 90%); flexible; stable in physiological conditions and in the presence of trypsin for 12 days; able to release the bioactive compounds in a controlled manner; based on Fickian diffusion; and biocompatible towards the main skin cells, keratinocytes and fibroblasts. Furthermore, reactive oxygen species (ROS) production tests demonstrated the high capacity of our films to reduce the oxidative stress induced in cells, which is responsible for various skin diseases.

纳米CaCO3/柞蚕丝素复合膜的制备及结构表征

制备了一种含有纳米CaCO3的新型柞蚕丝素蛋白膜,通过SEM、DSC、TG、XRD和IR研究了纳米CaCO3的加入对这种丝素蛋白膜性能的影响。SEM测试表明,纳米CaCO3粒子能均匀分散在丝素膜中不团聚;DSC测试表明,适量加入纳米CaCO3复合膜的Tm有所提高,但随着纳米CaCO3含量增加,Tm又有所降低;TG测试结果表明,随着纳米CaCO3加入量增加,复合膜的热稳定性得到提高;XRD测试结果表明,丝素结晶结构从silk I向silk II转化,结晶度得到提高。IR测试结果佐证了前面的推断。

活化方法对废旧涤/棉混纺织物回收利用的影响

为了更好的溶解废旧涤棉混纺织物中的含棉成分,论文采用四种活化方法对废旧涤棉混纺织物进行活化并在四种活化方法中寻找最适合的活化方法,其原则是应尽量减少对涤纶各方面的影响和增加棉纤维素的溶解度。通过研究四种活化方法对废旧涤棉混纺织物中涤纶的质量、拉伸性能、化学结构的影响,发现氢氧化钠和氢氧化钠+超声波对涤纶各方面的的影响较小,可用于活化废旧涤棉混纺织物;然后研究此两种活化方法对棉纤维素结构和溶解性的影响,发现氢氧化钠+超声波活化方法最适合用来活化废旧涤棉混纺织物。     

Electromagnetic interference shielding,mechanical properties and water absorption of copper/bamboo fabric (Cu/BF) composites

Copper/bamboo fabric (Cu/BF) composites were prepared by electroless deposition via a tin-free process. The process involved 3-aminopropyltrimethoxysilane modification, noble metal (Au or Pd) activation and electroless copper planting of BF. The copper deposition rate via Pd catalytic process was 1.01 mg/cm² h, higher than that by Au catalytic process (0.85 mg/cm² h). The microstructure of Cu/BF composites was analyzed by scanning electron microscopy (SEM), and the copper coatings were composed of ball-shaped copper particles. The composition and chemical state of copper layers were measured by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) spectra, Cu⁰ was detected but copper dioxide was not found in both spectra. The electromagnetic interference, water absorption, mechanical tension, conductivity and adhesion properties of Cu/BF samples (weight ratio of Cu/BF: 0.36 ± 0.01) were measured to obtain the qualities of the composites.     

Plenary Session: The Operator's Reliability and Safety in Industry L'Homme Agent d'infiabilite et de Fiabilite du Processus Industriel

When we look at the course of development of world civilization, we can recognize that the speed of development is becoming faster and faster. The author tries to examine the possible danger of this accelerated speed or change and to explain Japan's high pitch development after the opening of her door to the western world about 100 years ago. Ho also explains how human factors studies have been developing in Japan and their significance with regard to social change. Concerning this rapidly changing world civilization, he discusses the mission of human factors research in the future and the ways to maintain humanity.
