background: antibiotic resistant bacteria can be considered as a main problem in infection management. zinc oxide nanoparticles (zno nps), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. methods: in this study, zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

Tetrakis(permethyl-beta-cyclodextrin)-modified zinc(II) porphyrin (1) and tetra(beta-cyclodextrin)-modified zinc(II) porphyrin (2) were synthesized via "click chemistry". Intermolecular inclusion complexation of these structurally similar 1 and 2 with tetrasodium tetraphenylporphyrintetrasulfonate (3) led to formation of two distinctly different nanoarchitectures with alternate porphyrin and cy...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...

Incorporation of vertically aligned nanorod/nanowire arrays of metal oxide (oxide-NAs) with a polymer can produce efficient hybrid solar cells with an ideal bulk-heterojunction architecture. However, polymer/oxide-NAs solar cells still suffer from a rather low (normally, < 0.4 V) open-circuit voltage (Voc). Here we demonstrate, for the first time, a novel strategy to improve the Voc in polymer/...

UNLABELLED Ordered ZnO nanorod array/p-GaN heterojunction light-emitting diodes (LEDs) have been fabricated by introducing graphene as the current spreading layer, which exhibit improved electroluminescence performance by comparison to the LED using a conventional structure (indium-tin-oxide as the current spreading layer). In addition, by adjusting the diameter of ZnO nanorod array in use, the...

A large-scale growth of zinc oxide (ZnO) nanorod arrays on graphene sheets was fabricated by a hydrothermal technique, and the Fowler–Nordheim theory used to build model describe properties arrays’ field emission. The results indicated that morphological characteristics ZnO nanorods grown can be easily tuned varying reaction time concentrations solution. regular ordered were obtained under appr...

This letter proposes and experimentally demonstrates that oxygen, through action as a surfactant, enables the growth of aluminum nanorods using physical vapor deposition. Based on the mechanism through which oxygen acts, the authors show that the diameter of aluminum nanorods can be controlled from 50 to 500 nm by varying the amount of oxygen present, through modulating the vacuum level, and by...

Zinc oxide is known as a promising material for sensing devices due to its piezoelectric properties. In particular, the alignment of ZnO nanostructures into ordered nanoarrays is expected to improve the device sensitivity due to the large surface area which can be utilized to capture significant quantities of gas particles. However, ZnO nanorods are difficult to grow on the quartz substrate wit...

We reported well-integrated zinc oxide (ZnO) nanorod arrays (NRAs) on conductive textiles (CTs) and their structural and optical properties. The integrated ZnO NRAs were synthesized by cathodic electrochemical deposition on the ZnO seed layer-coated CT substrate in ultrasonic bath. The ZnO NRAs were regularly and densely grown as well as vertically aligned on the overall surface of CT substrate...
