Achieving Highly Efficient Atmospheric CO 2 Uptake by Artificial Upwelling

Sustainability (2018)

Yiwen Pan Long You Yi-Fan Li Wei Fan Chen‐Tung Arthur Chen

Artificial upwelling (AU) is considered a potential means of reducing the accumulation of anthropogenic CO 2 . It has been suggested that AU has significant effects on regional carbon sink or source characteristics, and these effects are strongly influenced by certain technical parameters, the applied region, and the season. In this study, we simulated the power needed to raise the level of deep ocean water (DOW) to designated plume trapping depths in order to evaluate the effect of changing the source DOW depth and the plume trapping depth on carbon sequestration ability and efficiency. A carbon sequestration efficiency index (CSEI) was defined to indicate the carbon sequestration efficiency per unit of power consumption. The results suggested that the CSEI and the carbon sequestration ability exhibit opposite patterns when the DOW depth is increased, indicating that, although raising a lower DOW level can enhance the regional carbon sequestration ability, it is not energy-efficient. Large variations in the CSEI were shown to be associated with different regions, seasons, and AU technical parameters. According to the simulated CSEI values, the northeast past of the Sea of Japan is most suitable for AU, and some regions in the South China Sea are not suitable for increasing carbon sink.

Fatigue behavior of the 3D orthogonal carbon/glass fibers hybrid composite under three-point bending load

Materials & Design (2019)

Wei Fan Wensheng Dang Tao Liu Juanzi Li Lili Xue

Hybrid composites containing more than one type of high performance fibers show better mechanical properties than traditional composites reinforced with one kind of fibers. This paper investigated the static and fatigue flexural properties of a newly designed 3D orthogonal carbon/glass fibers hybrid composite. The flexural properties of the 3D orthogonal carbon fibers composites and the laminated carbon/glass fibers hybrid composite were discussed to reveal the advantages of the static flexural properties of the 3D orthogonal carbon/glass fibers hybrid composite. 50%, 55%, and 60% of the maximum stress of the 3D orthogonal and laminated carbon/glass fibers hybrid composites were respectively selected for the three-point bending fatigue test. The failure propagation of the composites and their fracture morphologies were captured in detail using the 3D microscope. The results found that the 3D integrated structure and hybrid effects resulted in the 3D orthogonal carbon/glass fibers hybrid composite showing the best static flexural strength. The fatigue performance of the 3D orthogonal carbon/glass fibers hybrid composite was superior to the laminated carbon/glass fibers hybrid composite since Z-direction yarns were beneficial to resist the interface failure. The stress levels contributed to the variations of the failure modes of the composites under three-point bending fatigue loading.

An Antisweat Interference and Highly Sensitive Temperature Sensor Based on Poly(3,4-ethylenedioxythiophene)–Poly(styrenesulfonate) Fiber Coated with Polyurethane/Graphene for Real-Time Monitoring of Body Temperature

ACS Nano (2023)

Wei Fan Tong Liu Fan Wu Shujuan Wang Shengbo Ge

Body temperature is an important indicator of human health. The traditional mercury and medical electronic thermometers have a slow response (≥1 min) and can not be worn for long to achieve continuous temperature monitoring due to their rigidity. In this work, we prepared a skin-core structure polyurethane (PU)/graphene encapsulated poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) temperature-sensitive fiber in one step by combining wet spinning technology with impregnation technology. The composite fiber has high sensitivity (-1.72%/°C), super-resolution (0.1 °C), fast time response (17 s), antisweat interference, and high linearity (R2 = 0.98) in the temperature sensing range of 30-50 °C. The fiber is strong enough to be braided into the temperature-sensitive fabric with commercial cotton yarns. The fabric with good comfort and durability can be arranged in the armpit position of the cloth to realize real-time body temperature monitoring without interruption during daily activities. Through Bluetooth wireless transmission, body temperature can be monitored in real-time and displayed on mobile phones to the parents or guardians. Overall, the fiber-based temperature sensor will significantly improve the practical applications of wearable temperature sensors in intelligent medical treatment due to its sensing stability, comfort, and durability.

Comparisons of influence of random defects on the impact compressive behavior of three different textile structural composites

Materials & Design (2019)

Tao Liu Wei Fan Xianyan Wu

Carbon fiber breakage as one kind of defects that inevitably exists in composites has a distinct effect on the mechanical properties of textile structural composites. This paper investigated the influence mechanisms of random defects on compressive properties of plain woven composites, angle interlock woven composites and braided composites with the numerical simulation method. Based on the actual geometrical architecture of the plain woven, angle interlock woven and braided preforms, three microstructural models were built separately to simulate the impact compressive behavior of each composite. Random defects with different volume fractions ranging from 2% to 10% were introduced into the fiber tows in each microstructural model using the Monte Carlo method. The results reveal that random defects in fiber tows give rise to various reductions of the compressive strength and modulus due to the different fiber orientations and fracture mechanisms. Compared with the ideal model, the proposed finite element analysis (FEA) model introducing random defects can more accurately predict the compressive strength, compressive modulus and damage pattern of textile structural composites.

Enhancement of Piezoelectric Properties of Flexible Nanofibrous Membranes by Hierarchical Structures and Nanoparticles

Polymers (2022)

Feng Wang Hao Dou Cheng You Jin Yang Wei Fan

Piezoelectric nanogenerators (PENGs) show superiority in self-powered energy converters and wearable electronics. However, the low power output and ineffective transformation of mechanical energy into electric energy l limit the role of PENGs in energy conversion and storage devices, especially in fiber-based wearable electronics. Here, a PAN-PVDF/ZnO PENG with a hierarchical structure was designed through electrospinning and a hydrothermal reaction. Compared with other polymer nanofibers, the PAN-PVDF/ZnO nanocomposites not only showed two distinctive diameter distributions of uniform nanofibers, but also the complete coverage and embedment of ZnO nanorods, which brought about major improvements in both mechanical and piezoelectric properties. Additionally, a simple but effective method to integrate the inorganic nanoparticles into different polymers and regulate the hierarchical structure by altering the types of polymers, concentrations of spinning solutions, and growth conditions of nanoparticles is presented. Further, the designed P-PVDF/ZnO PENG was demonstrated as an energy generator to successfully power nine commercial LEDs. Thus, this approach reveals the critical role of hierarchical structures and processing technology in the development of high-performance piezoelectric nanomaterials.

The effect of reinforced structure on thermo-oxidative stability of polymer-matrix composites

Journal of Industrial Textiles (2015)

Wei Fan Jialu Li Yuanyuan Zheng Dandan Guo

A new concept in improving the thermo-oxidative stability of carbon fiber polymer-matrix composites (CFPMCs) by adopting integral reinforced structure was investigated. Specimens of three-dimensional and four-directional braided carbon fiber/epoxy composites (BC) and laminated plain woven carbon fiber/epoxy composites (LC) were subjected to isothermal aging at 90℃, 120℃, and 150℃ in air circulating ovens for various durations up to 13 days. The process resulted in progressive deterioration of the matrix reins and fiber/matrix interfaces, in the form of chain scissions, weight loss, and fiber/matrix debonding, which significantly led to the decrease of the flexural strength. Besides, the flexural properties’ retention rates of BC were higher than those of LC at the same aging conditions due to the difference of the reinforced structures. On the one hand, LC lost more weight than that of BC because the percentage of fiber ends area exposure to air in LC specimen was three times more than that in BC specimen. On the other hand, the BC specimens can resist the flexural load as an integral structure although the resin was damaged and the adhesive force between fiber bundles and resin decreased after thermo-oxidative aging, and no delamination happened like the LC specimens. Therefore, adopting three-dimensional and four-directional braided preform as the reinforcement of CFPMCs is an effective way to improve their thermo-oxidative stability.

Investigation of magnetization dynamics damping in Ni80Fe20/Nd-Cu bilayer at room temperature

AIP Advances (2018)

Wei Fan Qiang Fu Qian Qian Qian Chen Wan‐Ling Liu

Focusing on the Ni80Fe20 (Py)/Nd-Cu bilayers, the magnetization dynamic damping from spin pumping effect is investigated systematically by doping itinerant Cu in rear earth metal Nd. Various Ta/Py/Nd1-xCux/Ta/Si films with x = 0%, 16%, 38%, 46% and 58% are prepared by magnetron sputtering. For every content of Cu, the thickness of Nd-Cu layer is changed from 1 nm to 32 nm. The damping coefficient increases with increasing the thickness of Nd-Cu layer, which shows the trend of the spin pumping behavior. Also, with increasing Cu concentration in the Nd-Cu layer, the damping coefficient decreases, implying that the spin-orbit coupling in Nd-Cu layer is indeed cut down by high itinerant of Cu dopants. It is interesting that the spin diffusion length (λSD) in the Nd-Cu layer for different Cu dopants is not found to increase monotonously.
