A thiophene-based donor-acceptor phenothiazine dye has been functionalized with a peripheral glucose unit (PTZ-GLU) to bust its affinity water and enhance dye-sensitized photogeneration of hydrogen. Compared the corresponding alkyl derivative (PTZ-ALK), as well common hydrophilic triethylene glycol substitution (PTZ-TEG), sugar shows lower contact angle; PTZ-GLU performed twice more efficient than PTZ-TEG in hydrogen terms evolved gas turnover number.
Photocatalytic reactions could enhance the share of chemicals produced through renewable sources. The efficiency photocatalysts drastically depends on light absorption, surface energy crystals, and properties nanobuilding blocks assembled in devices. Here, we show that photoelectrochemical water oxidation brookite TiO2 nanorods is greatly enhanced by engineering location Au nanoparticles deposition. Brookite photoanodes a very low onset potential for to H2O2 −0.2 VRHE due energetics exposed...
Dibranched donor-(π-acceptor)2 dyes, where phenothiazine is the donor core, cyanoacrylic acid acceptor/anchoring group, and π represented by mono- poly-cyclic simple fused thiophene derivatives, were tested as photosensitizers in photocatalytic production of H2 , combination with a Pt/TiO2 catalyst. The optical electrochemical properties dyes investigated, showing that careful design thiophene-based spacer afforded enhanced properties. In over 20 h, new sensitizers revealed improved...
This study analyzed the use of cork-derived biochar, obtained through pyrolysis, as a more sustainable additive than traditional carbon materials. In addition, present explored its application in polymer matrix manufacturing via stereolithography. To best our knowledge, this approach has not been reported scientific literature. The cork biochar retained morphology original and integrated well into photocurable polymer, demonstrated by scanning electron microscopy. integration can contribute...
Background: Air pollution has become an important issue worldwide due to its adverse health effects.Among the different air contaminants, volatile organic compounds (VOCs) are liquids or solids with a high vapor pressure at room temperature that extremely dangerous for human health.Removal of these can be achieved using nanomaterials tailored properties such as carbon nanotubes.Methods: Vertically-aligned multiwall nanotubes (CNTs) were successfully grown on quartz filters by means plasma...
Polymer nanocomposites (PNCs) attract the attention of researchers and industry because their potential properties in widespread fields. Specifically, electrically conductive semiconductor PNCs are gaining interest as promising materials for biomedical, optoelectronic sensing applications, among others. Here, metallic nanoparticles (NPs) extensively used nanoadditives to increase electrical conductivity mere acrylic resin. As situ formation NPs within matrix is hindered by solubility NP...
Abstract This work reports on the design and preparation of composites based a high impact acrylonitrile‐butadiene‐styrene polymer matrix filled either with aluminium microparticles or graphite nanoplatelets. A surfactant tin were further added to improve dispersion adhesion fillers in an attempt conductivity materials. The obtained via twin‐screw extrusion their performance fused filament fabrication was successfully tested compared other conventional ways manufacturing plastic parts....
Stereolithography is an additive manufacturing technology commonly used to build either prototypes or final parts. Nevertheless, the manufacture of structural parts has been ruled out owing poor mechanical properties conventional UV-curable resins. Moreover, inventory available commercial resins still limited and they exhibit low thermal electrical conductivity values. In this work, some composite materials were designed using Al microparticles dispersed within SLA resin matrix. These...
