A new metalloporphyrin-based conjugated microporous polymer, NiP-CMP, was constructed via a homo-coupling polymerization reaction. NiP-CMP possesses a high BET surface area of over 2600 m(2) g(-1), a large pore volume of 2.288 cm(3) g(-1), good stability, and displays excellent guest uptake of 202 wt% in iodine vapour…
In this paper, we experimentally demonstrated the reprocessing, recycling and repairing abilities of pulverized thermoset polymer with exchangeable bonds.
ions are in situ reduced into metallic silver nanoparticles by the "bridge" of the polydopamine coating, and the formed Ag nanoparticles are home positioned. As polydopamine is an environmentally friendly reagent with abilities as a universal adhesive to any surface and as a mild reductant for noble metal salts, becau…
ZnCo 2 O 4 NWCAs on Ni foam as electrodes for high-performance asymmetric supercapacitors.
Colloidal gold is very attractive for several applications in biotechnology because of its unique physical and chemical properties. Many different synthesis methods have been developed to generate gold nanoparticles (AuNPs). Here, we will introduce these methods and discuss the differences between fabrication techniqu…
Magical spell have the ability to turn everything touched into gold, in real time scenario one such spell is “Nanotechnology” which has the mysterical power to revolutionize every field touched by it. Nanotechnology is now invading the food industry and establishing great potential.Nanotechnology applications in food…
Activated carbon and fiberglass are widely used in air filtration industry. Nanotechnology field is booming in an exceptionally impressive manner. Nanofibers are one of the unique materials which have one order of magnitude smaller than conventional fibers. The high surface-to-volume ratio, low resistance and enhanced…
A phosphor with remarkable long persistent luminescence features, Zn3Ga2Sn1O8:0.5 Cr3+, suitable for deep and reproducible tissue imaging has been rationally designed and successfully fabricated. This phosphor shows bright and long persistent luminescence over 300 h in the near-infrared region, and permits an enabling…
This paper reports on the structural, optical and photometric characterization of an Eu(3+)/Dy(3+) doped yttrium oxysulfide phosphor (Y2O2S:Eu(3+)/Dy(3+)) for near white emission in solid state lighting. A series of Y2O2S phosphors doped with Eu(3+)/Dy(3+) were prepared by the hydrothermal method. The microstructures…
AIMS: To synthesize, characterize, and analyze antimicrobial activity of AgNPs of Escherichia hermannii (SHE), Citrobacter sedlakii (S11P), and Pseudomonas putida (S5). METHODS: The synthesized AgNPs were examined using ultraviolet-visible spectroscopy (UV-vis) and, zeta potential, and the size and the morphology obta…
Graphene has been widely studied for its many extraordinary properties, and other two-dimensional layered materials are now gaining increased interest. These excellent properties make thin layer materials very attractive for integration into a wide variety of technologies, particularly in flexible optoelectronic devic…
Graphene oxide (GO) and reduced graphene oxide (rGO) sheets have usually been synthesized through Hummers' method by using highly pure graphite (HPG) as the main starting material. However, HPG can be relatively expensive for mass production of high-quality graphene. In this work, a general method for synthesis of hig…
Synergistic combination of metal nanoparticles and graphene modulates electronic properties of graphene, leading to enhancement in gas sensitivity and selectivity.
The distinctive architecture of the PANI/3D graphene electrode enhances its supercapacitive performance (1024 F g ¬1 ), the lightweight and porous conducting foam provides “freeways” for fast charge transport.
Graphene oxide (GO) is an emerging material for surface-enhanced Raman scattering (SERS) due to its strong chemical enhancement. Studying the SERS performance of plasmonic nanoparticle/GO hybrid materials at the single particle level is crucial for direct probing of the chemical effect of GO on plasmonic nanoparticles…
Silver and gold nanoparticles were synthesized using an aqueous extract of the seaweed Turbinaria conoides and their antibiofilm activity against marine biofilm forming bacteria is reported here. The UV-Vis spectra showed the characteristics SPR absorption band for Ag NPs at 421 and for Au NPs at 538 nm. Further, the…
