- Bamboo-derived cellulose fibers/RGO carbon aerogel composite was prepared by using a facile aerogel-based method, in which bamboo pulp fibers were dissolved and incorporated in an ionic liquid system, and RGO was introduced by thermal reduction approach. The obtained bamboo-derived cellulose fibers/RGO carbon aerogel composite shows a large specific surface area, and excellent electrochemical performance. When the GO content was 2.5 wt%, the obtained composite showed a high specific surface area of 1957 m(2)/g, and high specific capacitance of 351 F/g in 6 M KOH electrolyte solution even with a more than 90% capacitance retention at a high scan rate of 200 mV/s. The bamboo-derived cellulose fibers/RGO composite electrodes show the low equivalent series resistance of 5.0 Omega and small charge transfer resistance of 0.30 Omega which further demonstrate the excellent electrochemical behaviors.

- Cellulose acetate (CA) ultrafiltration membranes are attracting more attention in wastewater purification due to its biodegradability and eco-friendly. The application of CA membranes, however, is limited by high susceptibility to bacterial corrosion and lack of mechanical tolerance that results in loss of life. To solve the above problems, we first fabricated the CA-based composite membranes incorporated with bamboo-based lignocellulose nanofibrils (LCNFs) by a strategy of phase inversion. LCNFs was prepared by using a combined method of one-step chemical pretreatment and add hydrolysis coupled with high-pressure homogenization. The as-prepared CA/LCNFs composite membranes with 4 wt% lignin in the LCNFs exhibited high tensile strength of 7.08 MPa and strain-at-break of 12.21%, and high filtration permeability of 188.23 L. m(-2).h(-1) as ultrafiltration membranes for wastewater treatment, which could obviously inhibit the growth of Escherichia Coli.

- Advances in vehicle technology open up both opportunities and challenges for human-machine interface (HMI) design in intelligent vehicles. Design guidelines for icons in central consoles of vehicles have been discussed in human-computer interaction community, but more study and innovation are needed in icon design. In this paper, we investigated the displayed line thickness and size of icons in the intelligent vehicle’s central control screen, based on international design guidelines and standards. The experiment involved 17 participants performing simulated in-vehicle secondary task. The result from the experiments shows that the usability of icons increases and the driver’s workload decreases as the icons get larger. We also found a set of recommended values for size and line thickness of icons in this context. Future work will focus on providing design guidelines for other aspects of HMI design in intelligent vehicles.
