Detailed morphological and structural characterization of high-aspect-ratio polyaniline nanofibers obtained using a small amount p-aminodiphenylamine (dimer) or p-phenylenediamine (diamine monomer) as an initiator into rapidly mixed reaction is presented. Structural characteristics have been investigated by FT-IR, UV−vis−NIR, solid-state 13C NMR, 15N while the morphology was examined scanning electron microscopy (SEM) transmission (TEM). Nanofibers with addition appear longer less entangled...
ABSTRACT Three‐dimensional (3D) printing brings exciting prospects to the realm of conjugated polymers (CPs) and organic electronics through vastly enhanced design flexibility, structural complexity, environmental sustainability. However, use 3D for CPs is still in its infancy remains full challenges. In this review, we highlight recent studies that demonstrate proof‐of‐concept strategies mitigate some these problems. Two general additive manufacturing approaches are featured: direct ink...
Complex 3D geometry and high conductivity have generally been mutually exclusive characteristics for conducting polymers. For instance, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a benchmark polymer, typically exhibits 1 to 2 orders of magnitude lower in 3D-printed forms compared 2D-processed thin films, due its sensitivity processing conditions. Here, we investigate the main causes this reduced conductivity, which are found be (1) ink formulation strategy (2)...
Rationally designed, 3D-printed architectures can effectively decouple the mechanical and electrical properties of conducting polymer hydrogels.
Cemented Sand, Gravel, and Rock (CSGR) dams have traditionally used either Conventional Vibrated Concrete (CVC) or Grout-Enriched Roller Compacted (GERCC) for protective seepage control layers in low- to medium-height dams. However, these methods are complex, prone interference, uneconomical due significant differences the expansion coefficient, elastic modulus, hydration heat parameters among CSGR, CVC, GERCC. This complexity complicates quality during construction, leading development of...
AIM: To assess the visual outcomes and corneal biomechanical properties of myopia patients between laser in situ keratomileusis (LASIK) LASIK combined with accelerated crosslinking (LASIK Xtra). METHODS: This prospective study analyzed 52 consecutive treated Xtra 45 LASIK. Only right eyes two groups were analyzed. The uncorrected distance acuity (UDVA), keratometry values, postoperative central thickness (CCT), demarcation line depth, compensated intraocular pressure (IOPcc),...
Abstract Magnetic levitation of the fusion target by coating a thin MgB 2 superconducting shell on its outer surface has recently been proposed in inertial confinement (ICF) to realize non-contact support at ~20 K boost implosion performance and yield. To avoid possible effect ablation, coated is anticipated be as while fulfilling requirements. Under this circumstance, fabrication with reduced thickness explored using hybrid physical-chemical vapour deposition method. By gradually decreasing...
Peripheral nerve blocks are an important part of postoperative analgesia for the extremities. Previously, we reported that a single shot 0.375% ropivacaine (20 mL) via ultrasound-guided popliteal sciatic and saphenous provided satisfactory after foot ankle surgery; however, toe weakness in early period became concern patients. Our preliminary data indicate 0.25% may be effective analgesia. Hence, hypothesized analgesic effect would noninferior to at same volume reduce degree weakness. In...
Abstract This study evaluated the performance of plusoptiX A12C in detecting amblyopia risk factors (ARFs) Chinese children aged 3-to-4-year. PlusoptiX examination was successfully conducted among 1,766 subjects without cycloplegia to detect refractive error, asymmetry and media opacity. Cycloplegic retinoscopy (CR) on 357 suspected having vision abnormalities. Statistical differences between CR device were confirmed using mean spherical value (+1.41 ± 0.87 D versus +1.14 0.81 D),...
AIM: To compare the effect of myopia and astigmatism correction postoperative change in higher-order aberration as results receiving small-incision lenticule extraction (SMILE) femtosecond laser-assisted situ keratomileusis (FS-LASIK). METHODS: A prospective non-randomized controlled study was conducted. The subjects are divided into two groups according to different operations received: 229 eyes 116 patients SMILE group 168 86 FS-LASIK group. All were followed up for 3mo by monitoring their...
Antibacterial plasticizers for medical PVC have been synthesized by the modification of bio-based engineering elastomers with a quaternary ammonium salt. blended such showed good antibacterial properties and biocompatibility.
