Heater plates or sheets that are visibly transparent have many interesting applications in optoelectronic devices such as displays, well defrosting, defogging, gas sensing and point-of-care disposable devices. In recent years, there been advances this area with the advent of next generation conducting electrodes (TCE) based on a wide range materials oxide nanoparticles, CNTs, graphene, metal nanowires, meshes their hybrids. The challenge has to obtain uniform stable temperature distribution...
Transparent conducting electrodes (TCEs) have been made on flat, flexible, and curved surfaces, following a crack template method in which desired surface was uniformly spray-coated with crackle precursor (CP) metal (Ag) deposited by vacuum evaporation. An acrylic resin (CP1) SiO2 nanoparticle-based dispersion (CP2) derived from commercial products served as CPs to produce U-shaped cracks highly interconnected networks. The width the density could be controlled varying spray conditions,...
Transparent supercapacitors hold great promise for futuristic electronics. This review discusses about the choice of electrode materials achieving desirable transparency in without sacrificing energy storage capacity.
Virtually unlimited and highly interconnected Cu wire networks have been fabricated on polyethylene terephthalate (PET) substrates with sheet resistance of <5 Ω □−1 transmittance ∼75%, as alternatives to the commonly used tin doped indium oxide (ITO) based electrodes. This is a four step process involving deposition commercially available colloidal dispersions onto PET, drying induce crackle network formation, nucleating Au or Pd seed nanoparticles inside regions, washing away sacrificial...

The electrodes consist Au wire networks obtained by crackle template method...
Theoretical and experimental studies are performed to establish the importance of a thin overlayer on metal mesh as an ITO-alternative transparent conducting electrode for liquid crystal smart windows where uniform electric field is essential.
In the present work, gold (Au), silver (Ag), and copper (Cu) based mono- bimetallic NPs are prepared using a cost-effective facile wet chemical route. The pH for synthesis is optimized in accordance with optical spectra supported by finite difference time domain simulation studies. FESEM TEM micrographs used to analyze morphology of nanoparticles. images nanoparticles (BMPs) verified their nature. XRD studies confirmed formation fcc-structured NPs. Photoluminescence as-synthesized good...
A metal (Au) wire network, nearly invisible to the naked eye, has been realized on common substrates such as glass, serve a transparent conducting electrode (TCE). The process involves coating TiO2 nanoparticle dispersion film thickness of ~10 μm, which following solvent evaporation, spontaneously forms crackle network; is then used sacrificial template for deposition. TCE thus formed exhibited visible transmittance ~82% and sheet resistance 3–6 Ω/square fill factor 7.5%. With polyethylene...
This study presents the fabrication of highly conducting Au fabric electrodes using a layer-by-layer (LBL) approach and its application toward energy storage. Through ligand-exchange mechanism, alternating layers tris(2-aminoethyl)amine (TREN) gold nanoparticles (Au NPs) encapsulated with tetraoctylammonium bromide (TOABr) ligands (Au-TOABr) were deposited onto to achieve (0.12 Ω/□) at room temperature in just two LBL cycles. In contrast several existing techniques, current realizes (7-15...

Chatbot, a computer program that simulates human conversation, or chat, through artificial intelligence an chat bot will be used to give information answers any question asked by user related bank. It is more like virtual assistant, people feel they are talking with real person. They speak the same language we do, can answer questions. In banks, at care centres and enquiry desks, insufficient usually takes long time process single request which results in wastage of also reduce quality...
