Tuberose (Polianthes tuberosa L.) is an important commercial cut flower that has a short vase life. An experiment was carried out by using five different levels of humic acid (HA) (0, 25, 50, 75, and 100 mg L-1) and seven different levels of silver nano-particles (SNP) (0, 0.5, 1, 2, 3, 4 and 5 mg L-1) mixed with 1.5% sucrose on cut tuberosa cv. Single flower. The loss of fresh weight on third ...

Current lithography techniques, which employ photon, electron, or ion beams to induce chemical or physical reactions for micro/nano-fabrication, have remained challenging in patterning chemically synthesized colloidal particles, which are emerging as building blocks for functional devices. Herein, we develop a new technique - bubble-pen lithography (BPL) - to pattern colloidal particles on subs...

As an important interconnection material in electronics, conductive silver paste has attracted much research interest chip packaging and printed circuit board due to its predominant properties like high conductivity flexible interconnection. In this paper, the nanoparticles, sphere particles, flake powders are fabricated by various methods. Different proportions of powder selected prepare micro...

This research is concerned with the fungicidal properties of nano-size silver colloidal solution used as an agent for antifungal treatment of various plant pathogens. We used WA-CV-WA13B, WA-AT-WB13R, and WA-PR-WB13R silver nanoparticles (AgNPs) at concentrations of 10, 25, 50, and 100 ppm. Eighteen different plant pathogenic fungi were treated with these AgNPs on potato dextrose agar (PDA), ma...

The aim of this project was to compare cerium oxide and silver particles of different sizes for their potential for uptake by aquatic species, human exposure via ingestion of contaminated food sources and to assess their resultant toxicity. The results demonstrate the potential for uptake of nano and larger particles by fish via the gastrointestinal tract, and by human intestinal epithelial cel...

An in vitro study was conducted to know the veridical properties of silver nanoparticles synthesized from   locally available white button mushrooms (Agaricus bisporus). The characterized colloidal silver nanoparticles exhibited as an excellent virucidal property on viral strain Bacteriophage. The viral inactivation process was increased with increasing the concentration of colloidal s...

Taking advantage of the aromatic and cross-linking tendency of lignin macromolecules extracted from plants, we present a novel method for their assembly into supracolloidal structures. Specifically, spherical particles with controllable size (∼90 nm to 1 μm) were obtained from water-in-oil (W/O) microemulsions formulated with a mixture of nonionic surfactants and a colloidal dispersion of a low...

Epitaxial growth, a bottom-up self-assembly process for creating surface nano- and microstructures, has been extensively studied in the context of atoms. This process, however, is also a promising route to self-assembly of nanometer- and micrometer-scale particles into microstructures that have numerous technological applications. To determine whether atomic epitaxial growth laws are applicable...
