In the last 15 years, more than 50,000 papers with zinc oxide (ZnO) in title are listed within ISI database. The outstanding popularity of ZnO has many reasons; most important one appears to be its multi-functionality, resulting applications physics, chemistry, electrical engineering, material science, energy, textile, rubber, additive manufacturing, cosmetics, and pharmaceutical or medicine, as well ease grow all kinds nano- microstructures. A key structure is tetrapod-shaped (T-ZnO), which...
Growth of freestanding nano- and microstructures with complex morphologies is a highly desired aspect for real applications nanoscale materials in various technologies. Zinc oxide tetrapods (ZnO-T), which exhibit three-dimensional (3D) shapes, are major importance from technological point view, thus efficient techniques growth different varieties tetrapod-based networks demanded. Here, we demonstrate the versatile single-step synthesis ZnO-T arm by simple flame transport (FTS) approach,...
Two flame-based synthesis methods are presented for fabricating ZnO-nanostructure-based UV photodetectors: burner flame transport (B-FTS)and crucible (C-FTS). B-FTS allows rapid growth of ZnO nanotetrapods and in situ bridging them into electrical contacts. The photo detector made from interconnected nanotetrapod networks exhibits fast response/recovery times a high current ratio under illumination.
An ultra lightweight carbon microtube material called Aerographite is synthesized by a novel single-step chemical vapor deposition synthesis based on ZnO networks, which presently the lightest known with density smaller than μg/cm(3). Despite its low density, hierarchical design leads to remarkable mechanical, electrical, and optical properties. The first experiments electrodes confirm applicability.
Flexible, electrically conducting, high temperature stable ceramics with very porosities are fabricated from interpenetrated metal oxide nano-microstructures in a versatile manner novel flame transport synthesis approach. The Young's modulus of these networks can be tuned wool type to rubber like based on the density, and interconnections building blocks. Semiconducting behavior allows multifunctional applications electrical readout mechanical history. As service our authors readers, this...
Marine biofouling is a well-known massive problem: within the shortest time, ship hulls and other man-made submerged surfaces are inevitably populated by various marine organisms. causes severe economic environmental problems. Thus, effective control on of utmost importance. Since middle 20th century, scientists engineers have developed antifouling coatings mainly based continuous release toxic metal ions accompanying booster biocides to repel or kill organisms approaching surface. However,...
Abstract Periodontitis is a prevalent chronic, destructive inflammatory disease affecting tooth‐supporting tissues in humans. Guided tissue regeneration strategies are widely utilized for periodontal generally by using membrane. The main role of these membranes to establish mechanical barrier that prevents the apical migration gingival epithelium and hence allowing growth ligament bone selectively repopulate root surface. Currently available have limited bioactivity potential. To address...

Abstract The visible-light-induced photocatalytic performance of a three-dimensional (3D) hybrid composite based on carbon nano-onion (CNO)-functionalized zinc-oxide tetrapods (T-ZnO) was investigated to study the degradation 2,4-dinitrophenol (DNP). CNO-functionalized T-ZnO 3D successfully developed via facile one-step process. CNOs, synthesized green route from flaxseed oil, were decorated surface chemical mixing. Such allows for complete optimization T-ZnO/CNO interface enhance...
Advanced wound scaffolds that integrate active substances to treat chronic wounds have gained significant recent attention. While and advanced functionalities previously been incorporated into one medical device, the wirelessly triggered release of has remained focus many research endeavors. To combine multiple functions including light-triggered activation, anti-septic, angiogenic, moisturizing properties, we developed a 3D printed hydrogel patch encapsulating vascular endothelial growth...
Abstract Current lithium (Li)‐metal anodes are not sustainable for the mass production of future energy storage devices because they inherently unsafe, expensive, and environmentally unfriendly. The anode‐free concept, in which a current collector (CC) is directly used as host to plate Li‐metal, by using only Li content coming from positive electrode, could unlock development highly energy‐dense low‐cost rechargeable batteries. Unfortunately, dead Li‐metal forms during cycling, leading...

Even though no additional crosslinking exists between nanotubes, high reinforcement effect compression tensile characteristics...
Abstract Virtually all efforts to generate an effective protection against the life-long, recurrent genital infections caused by HSV-2 have failed. Apart from sexual transmission, virus can also be transmitted mothers neonates, and it is a key facilitator of HIV coacquisition. In this article, we uncover nanoimmunotherapy using specially designed zinc oxide tetrapod nanoparticles (ZOTEN) with engineered oxygen vacancies. We demonstrate that ZOTEN, when used intravaginally as microbicide,...
