concave nanostructures may be developed to improve the specific mass activity of a catalyst for formic acid and methanol electro-oxidation. In this work, we report the elctrocatalytic oxidation of methanol and formic acid in acid medium over concave Pt-Cu-Fe ternary nanocubes（NCs）, obtained by the galvanic exchange of Pt and Fe on Cu NCs. The concave Pt-Cu-Fe NCs exhibited improved electrooxidation performance contrasted to Pt-Cu NCs and purchased commercial Pt/C as demonstrated by their improved durability, lower onset potential, and more preferable anti-poisoning properties. These properties are believed to originate from the tailored concave structure of the catalyst and possible synergetic effects among the components of the Pt-Cu-Fe NCs.

Infertility affects 10-15% of couples, male factors account for nearly half of all infertility cases. Although modern diagnostic and therapeutic methods are available, unfortunately, approximately 50% of infertility cases are still unexplained. Traditional Chinese Medicine (TCM) has a comprehensive theoretical framework on the essence of body health status among body parts and internal organ systems. This study was designed to explore the relationship between Electric resistances at 24 Jingluo starting points and male infertility. The preliminary results indicate that compared to the normal male population, the inferile men have obvious different electric resistances values in Fei Jing, Gan Jing, Pi Jing, Wei Jing, Dan Jing, Shen Jing, Pangguang Jing (P<0.05) et al, which may lay down the scientific foundation for the next generation of underclothes bioengineering design.

A series of novel type temperature and pH responsive hydrogels were synthesized by using hydroxypropylcellulose (HPC) as temperature sensitivity material, sodium alginate (SA) as pH sensitivity material. The effect of SA on lower critical solution temperature (LCST) has been studied and the influence mechanism is presented. In addition, the swelling ratio and control factors of swelling process are all researched in this paper. The main results obtained are as follows: the LCST of HPC/SA hydrogel decreased gradually as SA was added into HPC;this kind of hydrogel responded temperature and pH double-sensitive;the swelling ratio reached the maximum value at pH of 6.

The demand for advanced fiber biomaterials and medical devices has risen rapidly with the increasing of aging population in the world. To address this grand societal challenge, textile biomedical engineering(TBE) has been defined as a holistic and integrative approach of designing and engineering advanced fiber materials for fabricating textile structures and devices to achieve various functions such as drug delivery, tissue engineering and artificial implants, pressure therapy and thermal therapy,bioelectric/magnetic detection and stimulation for the medical treatment and rehabilitation of human body. TBE is multidisciplinary in nature and needs integration of cross disciplinary expertise in medical science, healthcare professionals, physiologists, scientists and engineers in chemistry, materials, mechanics, electronics, computing, textile and designers. Engineering fiber materials and designing textile devices for biomedical applications involve the integration of the fundamental research in physics, chemistry, mathematics, and computational science with the development of engineering principles and understanding on the relationship between textile materials/devices and human physiology, behaviour, medicine and health. Theoretical concepts have been advanced together with creating new knowledges created from molecules to cells, organs and body-textile systems, and developing advanced fiber materials, innovative textile devices and functional apparel products for healthcare,comfort, protection against harmful external environment, diseases prevention, diagnosis and treatment, as well as rehabilitations. A holistic, integrative and quantitative approach has been adopted for deriving the technical solutions of how to engineer fibers and textiles for the benefits of human health. This paper reviews the theoretical foundations for textile biomedical engineering and advances in the recent years.

A series of thermo-sensitive blending films were prepared from hydroxypropylcellulose and polyarcylonitrile. The effects of materials ratio, pH value and temperature on these blended films swelling velocity were characterized. As temperature was lower than LCST, different results are found while dipping blend films samples in acid or base condition respectively. Results from pH value was 1.4 which showed that swelling velocity of HPC/PAN blending films increased with the addition of HPC, film’s swelling was mainly controlled by polymer chain relaxation. But, it was controlled by water molecules diffusion under pH value of 7.4. Swelling velocity was also effected by both temperature and pH value.

目前智能可穿戴设备大多为智能手表、手环等,具有刚性大、舒适性差和需要频繁充电的问题,难以满足人体工效学和服装舒适性的要求,无法长久穿戴实现全天候的监测。基于纺织品的摩擦纳米发电机(textile triboelectric nanogenerator, T-TENG)可集成到鞋服中作为柔性电源和自供电传感器使用,是一种理想的人体主动健康监测和执行的可穿戴器件。然而,目前报道的柔性可穿戴织物基器件大多需要经过封装处理后再集成到服装上,造成服装透气性下降。此外,目前的研究大多数处于实验室阶段,没有充分考虑T-TENG在实际使用过程中耐久性、灵敏性和稳定性等性能。本文综述了T-TENG的基本工作模式、材料选择、制造方法、集成鞋服的方式及应用场景,重点讨论了纳米纤维膜和纺织复合材料的T-TENG、纤维/纱线基T-TENG和织物基T-TENG的制备方法,提出了未来舒适型T-TENG的研发与在服饰上的集成新策略,包括T-TENG的规模化制备、T-TENG与传统服饰的一体化集成、T-TENG的监测精度与舒适性的兼容以及T-TENG的耐用性和稳定性。
