水触发材料因其操作简单、驱动柔和、成本低廉、环境友好等诸多优点受到越来越多的关注。但是,大多数此类材料通常具有较长的反应时间,并且需要严格的保存条件,这限制了它们在实践中的适应性。本研究提出并证明了一种基于Al-NaOH复合共晶镓-铟(eGaIn)合金的新型水触发材料,该材料具有快速响应性和可变形性。一旦加入水,制成的材料将在短短几秒钟内随着气体的产生而升温40 ℃,这表明它具有用作热驱动器和气动驱动器的巨大潜力。此外,研究还测试了新材料的可重复使用性和降解能力。并据此设计了双层结构的智能绷带,其内部填充了Al-NaOH复合eGaIn,而BiInSn则作为外部支撑材料。实验显示,厚度为2 mm的片状结构经过冷却处理后能够支撑1.8 kg的重物,这比常用的玻璃纤维高分子绷带的承重能力要好得多。同时,研究还使用Al-NaOH复合eGaIn制作了水触发球形机器人的原型,该原型在特定的外部刺激下实现了滚动和弹跳行为。这些发现表明,当前材料在开发未来的可穿戴设备、软驱动器和软机器人方面具有潜在价值。

A pneumatic cylinder driving polyhedron mobile mechanism

A novel pneumatic cylinder driving polyhedron mobile mechanism is proposed in this paper. The mechanism is comprised of 5 tetrahedrons which includes a pneumatic cylinder in each edge. It locomotes by rolling and the rolling principle refers to the center of mass (CM) of the mechanism moved out of the supporting area and let it tip over through the controlling of the motion sequence of these cylinders. Firstly, the mathematical model is built to analysis the relation between the configuration and the CM of the mechanism. Then, a binary control strategy is developed to simplify and improve the control of this mobile mechanism. After that, dynamic simulation is performed to testify the analytical validity and feasibility of the rolling gaits. At last, a prototype is fabricated to achieve the rolling successfully to demonstrate the proposed concept.

Development of soft kernel durum wheat

Kernel texture (grain hardness) is a fundamental and determining factor related to wheat ( spp.) milling, baking and flour utilization. There are three kernel texture classes in wheat: soft and hard hexaploid ( ), and very hard durum ( subsp. ). The genetic basis for these three classes lies with the Puroindoline genes. Phenotypically, the easiest means of quantifying kernel texture is with the Single Kernel Characterization System (SKCS), although other means are valid and can provide fundamental material properties. Typical SKCS values for soft wheat would be around 25 and for durum wheat≥80. Soft kernel durum wheat was created via homeologous recombination using the mutation, which facilitated the transfer of ca. 28 Mbp of 5DS that replaced ca. 21 Mbp of 5BS. The 5DS translocation contained a complete and intact locus and both puroindoline genes. Expression of the puroindoline genes in durum grain resulted in kernel texture and flour milling characteristics nearly identical to that of soft wheat, with high yields of break and straight-grade flours, which had small particle size and low starch damage. Dough water absorption was markedly reduced compared to durum flour and semolina. Dough was essentially unchanged and reflected the inherent gluten properties of the durum background. Pasta quality was essentially equal-to-or-better than pasta made from semolina. Agronomically, soft durum germplasm showed good potential with moderate grain yield and resistance to a number of fungal pathogens and insects. Future breeding efforts will no doubt further improve the quality and competitiveness of soft durum cultivars.
