Transparent conductive film on plastic substrate is a critical component in low-cost, flexible, and lightweight optoelectronics. Industrial-scale manufacturing of high-performance transparent flexible needed to enable wide-ranging applications. Here, we demonstrate continuous roll-to-roll (R2R) production based metal nanowire network fully encapsulated between graphene monolayer substrate. Large-area grown Cu foil via R2R chemical vapor deposition process was hot-laminated onto nanowires...
A novel roll-to-roll, etching-free, clean transfer of CVD-grown graphene from copper to plastic using surface-energy-assisted delamination in hot deionized water is reported. The process realized by penetration between the hydrophobic and a hydrophilic native oxide layer on foil.The transferred used as high-output flexible transparent triboelectric nanogenerator.
Abstract A simple, eco-friendly, and biomimetic approach using Thymus vulgaris ( T . ) leaf extract was developed for the formation of ZnO-Ag nanocomposites (NCs) without employing any stabilizer a chemical surfactant. used first time, in novel approach, green fabrication NCs as size based reducing agent via hydrothermal method single step. Presence phenols has served both capping agents that play critical role production NCs. The effect silver nitrate concentration studied. in-vitro...
Morphology management for tailoring the properties of monolayer transition-metal dichalcogenides (TMDCs), that is, molybdenum disulfide (MoS2), has attracted great interest promising applications such as in electrocatalysis and optoelectronics. Nevertheless, little progress been made engineering shape MoS2. Herein, we introduce a modified chemical vapor deposition method to grow MoS2 dendrites by pretreating substrates with adhesive tapes. The as-grown crystals are featured hexagonal...
Zinc oxide (ZnO) nanoflowers have huge potential for various applications. However, the growth mechanism of ZnO is still under debate despite mechanisms having been proposed. The aim this study to investigate different morphologies in a single sample; hopefully, might help understand exact nanoflowers. Herein, two models are proposed: (I) (shapes) and (II) sized flowers sample. present work also investigates how morphology assists tuning properties nanomaterials, which unclear date. New...
MOFs derived ZnCo–Fe nanocages are synthesized by a self-templated approach showing the remarkable performance for OER catalysts.
Monolayer MoS2 crystals with tailored morphologies have been shown to exhibit shape-dependent properties and thus potential applications in building nanodevices. However, a deep understanding of the relationship between shape defect structures monolayer is yet elusive. polygonal shapes, including triangle, tetragon, pentagon, hexagon, are grown using chemical vapor deposition technique. Compared other hexagon crystal contains more electron-donor defects that mainly due sulfur vacancies. In...
This paper presents a new high-output, flexible and transparent nanogenerator using chemical vapor deposition grown graphene as one of the friction layer. Graphene on copper is transferred onto polyethylene terephthalate by wet transfer method makes graphene-based triboelectric (TENG) have electrical conductivity high optical transmittance. We fabricated plasma treated thin layer polydimethylsiloxane structure another to improve output performance nanogenerator. Using this TENG, maximum...
Abstract The performance of 1D nano/microbeam‐based devices greatly relies on heat dissipation to substrates. surface roughness plays a key role in interfacial transport while this issue is seldom investigated due the difficulty quantitative determination thermal contact resistance (TCR) at nanoscale. Here, impact solid–solid interface by taking VO 2 microbeam Si substrate (VO /Si) as prototype investigated. With increased from atomic fluctuation ≈100 nm, it found that an unusual uncertainty...
The influence of Phthalic acid and TritonX-100 (TX-100) modified carbon paste electrode (MCPE) on the electrochemical behavior dopamine was investigated. response confirming from remarkable oxidation reduction peak current enhancement. process examined then all experimental parameters which affect dopamine, such as pH, scan rate, concentration immobilization surfactant were studied. Finally a sensitive simple voltammetric method developed for determination dopamine.
Transfer method of chemically vapor deposition graphene is an appealing issue to realize its application as flexible and transparent electrodes. A universal stamping transfer grown from copper onto different polymers (FTPs) reported here ensures simple, robust, rapid, clean low-cost. This relies on coating ethylene vinyl acetate (EVA) the graphene, binding EVA coated graphene/Cu with FTPs delamination by hydrogen bubbling process, which analogous used process where ink carries imprint object...
A carbon paste electrode (CPE) modified with poly (tannic acid) was used for the sensitive voltammetric determination of dopamine (DA) and epinephrine (EP).

Heat‐assisted blade‐coating (HABC) technique can be applied for scalable production of perovskite solar cells (PSCs). With the current setups, HABC is not applicable in ambient atmosphere due to adverse impact humidity on films. Here, a modified method reported achieve high quality films under harsh conditions. By using lead acetate trihydrate (PbAc 2 · 3H O) as source, rapid low‐temperature, short time annealing treatment discovered. It found that small amount hydrate water PbAC O source...
