Characterisation data for electrocharged facepiece respirator fabrics using common materials
<p>Face masks in general, and N95 filtering facepiece respirators (FRs) that protect against SARS-Cov-2 virion in particular, have become scarce during the ongoing COVID-19 global pandemic. We developed a technique for fabrication of electrocharged filtration layers employed in N95 FRs using commonly available materials and easily replicable methods. Our input polymer was polypropylene or polystyrene, and could include discarded plastic containers of these materials, and the fabrication setup was based on the cotton candy (CC) principle. We translate the primary parameters underlying the CC principle to simple design rules that allow anyone to construct their own fabrication system from common parts, or employ a commercial cotton candy machine with minimal modifications. Finally, we present basic characterization results for structural and filtration properties of electrocharged fabrics made using the CC principle. The data uploaded here belongs to our characterization studies for use by any interested party.</p>
Data from: Facile fabrication of microfluidic surface-enhanced raman scattering devices via lift-up lithography
We describe a facile and low-cost approach for flexible integration surface-enhanced Raman scattering (SERS) substrate in microfluidic chips. Briefly, a SERS substrate was fabricated by electrostatic assembly of gold nanoparticles, and shaped into designed patterns by the subsequent lift-up soft lithography. The SERS micropattern could be further integrated within microfluidic channels conveniently. The resulting microfluidic SERS chip allows one to ultrasensitively in-situ SERS monitor from the transparent glass window. With its advantages in simplicity, functionality, and cost-effectivity, this method can be readily expanded in optical microfluidic fabrication for biochemical applications.
Data from: Electrospinning repellents in polyvinyl alcohol-nanofibers for obtaining mosquito repelling fabrics
Recently, the use of repellents for preventing the transmission of mosquito-borne diseases is getting increasingly more attention. However, most of the current repellents are volatile in nature and must be frequently re-applied as their efficacy is only limited to a short period of time. Therefore, a slow release and abrasion resistant mechanism is needed for prolonging the protection time of these repellents. This study direct micro-encapsulation of repellents from an emulsion or integrating already encapsulated repellents into nanofibers via electrospinning. Different repellents were electrospun in polyvinyl alcohol (PVA) nanofibrous structures, namely p-menthane-3,8-diol (PMD) microcapsules, permethrin, chili and catnip oil. The repellents were successfully incorporated in the nanofibers and the tensile properties of the resulting samples did not have a significant change. This means that the newly created textiles will be identical to current PVA nanofibrous textiles with the added benefit of being mosquito repellent. Principally, all incorporated repellents in the nanofibrous structures showed a significantly reduced number of mosquito landings compared to the control. Consequently, the currently described method resulted in a new and very effective repelling textile material that can be used in the prevention against mosquito associated diseases.
Data from: Performance improvement of miniaturized ZnO nanowire accelerometer fabricated by refresh hydrothermal synthesis
Miniaturized accelerometers are necessary for evaluating the performance of small devices such as haptics, robotics and simulators. In this study, we fabricated miniaturized accelerometers using well aligned ZnO nanowires. The layer of ZnO nanowires is used for active piezoelectric layer of the accelerometer and copper was chosen as a head mass. Seedless and refresh hydrothermal synthesis methods were conducted to grow ZnO nanowires on the copper substrate and effect of ZnO nanowire length on the accelerometer performance was investigated. The refresh hydrothermal synthesis exhibits longer ZnO nanowires, 12 μm, than the seedless hydrothermal synthesis, 6 μm. Performance of the fabricated accelerometers was verified by comparing with a commercial accelerometer. The sensitivity of the fabricated accelerometer by the refresh hydrothermal synthesis is shown to be 37.7 pA/g, which is about 30 times larger than the previous result.
Data from: High-performance single-walled carbon nanotube transparent conducting film fabricated by using low feeding rate of ethanol solution
We report floating catalyst chemical vapor deposition synthesis of single-walled carbon nanotubes (SWCNTs) for high performance transparent conducting films (TCFs) using low feeding rate of precursor solution. Herein, ethanol acts as carbon source, ferrocene and thiophene as catalyst precursor and growth promoter, respectively. By adopting a low feeding rate of 4 μl/min, the fabricated TCFs present one of the lowest sheet resistances of ca. 78 ohm/sq. at 90% transmittance. Optical characterizations demonstrate that the mean diameter of high quality SWCNTs is up to 2 nm. Additionally, electron microcopy observations provide the evidences that the mean length of SWCNT bundles is as long as 28.4 μm while the mean bundle diameter is only 5.3 nm. Moreover, very few CNT loops can be found in the film. Remarkably, the fraction of individual SWCNTs climbs up to 24.6%. All those morphology data account for the superior optoelectronic performance of our SWCNT TCFs.
High-efficient fabrication of core-shell-shell structured SiO2@GdPO4:Tb@SiO2 nanoparticles with improved luminescence
<p>SiO2@GdPO4:Tb@SiO2 nanoparticles with core-shell-shell structure were successfully synthesized by a cheap silane coupling agent grafting method at room temperature. This method not only homogeneously coated rare earth phosphate nanoparticles on the surface of silica spheres, but also saved the use of rare earth resources. The obtained nanoparticles are consisted of SiO2 core with a diameter of ~210 nm, GdPO4:Tb intermediate shell with thickness of ~7 nm, and SiO2 outer shell with thickness of ~20 nm. This unique core-shell-shell structured nanoparticles exhibited strong luminescence properties compared with GdPO4:Tb nanoparticles. The core-shell-shell structured nanoparticles can effectively quench the intrinsic fluorescence of bovine serum albumin (BSA) through a static quenching mode. The as-synthesized nanoparticles show great potential in biological cell imaging and cancer treatment.</p>
Data from: Convenient fabrication of conjugated polymer semiconductor nanotubes and their application in organic electronics
Organic heterojunction is indispensable in organic electronic devices, such as organic solar cells (OSCs), organic light-emitting diodes (OLEDs) and so on. Fabrication of core-shell nanostructure provides feasible and novel way to prepare organic heterojunction, which is beneficial for miniaturization and integration of organic electronic devices. Fabrication of nanotubes which constitute the core-shell structure in large quantity is the key for the realization of application. In this work, a simple and convenient method to prepare nanotubes utilizing conjugated copolymer of perylene diimide and dithienothiophene (P(PDI-DTT)) was demonstrated. The relationship between preparation condition (solvent atmosphere, solution concentration and pore diameter of templates) and morphology of nanostructure was studied systematically. P(PDI-DTT) nanotubes could be fabricated in regular shape and large quantity by preparing the solution with appropriate concentration and placing Anodic Aluminum Oxide (AAO) template with nanopore diameter of 200 nm in the solvent atmosphere. The tubular structure was confirmed by scanning electron microscope (SEM). P(PDI-DTT) nanotubes exhibited electron mobility of 0.02 cm2V-1s–1 in field effect transistors under ambient condition. Light emitting nanostructures were successfully fabricated by incorporating tetraphenyl ethylene (TPE) into polymer nanotubes.

LRI-fabricated composite demonstrators for an aircraft fuselage on the basis of a Building Block design approach
<p>A Liquid Resin Infusion (LRI) fabrication process is presented for manufacturing of composite aircraft demonstrators. A Building Block (BB) assessment approach is adopted, structured in coupon, element and subcomponent level. The quality of fabrication is quantified in terms of porosity and fiber volume fraction and the properties of the composite ply are determined by means of micromechanical models and coupon mechanical tests. At element and subcomponent level, an aft-fuselage bulkhead joint and a floor beam are modeled and tested in full scale. Results provide a measure of process capabilities and parts quality, indicating low void content and stiffness comparable to a similar prepreg.</p>
