Abstract:

Biogenically synthesized silver and gold nanoparticles were evaluated for antifungal activity against Rhizoctonia solani causing sheath blight of rice. Both the nanoparticles were tested at 1, 5, 10, 50, 100 and 200 ppm along with chemical check against the pathogen. Silver nanoparticle (Ag NP) at 200 ppm showed the highest inhibition (73.39%) in the radial growth of R. solani, while gold nanoparticle (Au NP) at the same concentration inhibited the growth of the pathogen up to 60.83%. Study on mode of action of nanoparticle by electron microscopy showed that Ag NP accumulate inside the fungal

Abstract:

In recent years, several studies focused on the synthesis of lignin-based nanoparticle in aqueous solution and its potential applications of the drug carrier were investigated. In this study, soda lignin (SL) nanoparticles (i.d. 128–560 nm) were synthesized by the nanoprecipitation process at three different concentrations (1, 2, and 4 mg/mL THF) with various molecular sizes of soda lignin (NP-F1, NP-F2, and NP-F3) obtained from sequential solvent extraction. The average molecular weights of SL, F1, F2, F3, F4, and F5 were 3130, 1190, 2550, 3680, 5310, and 14,650, respectively. The average siz

The nanoparticles are densely grafted with polymer chains of chemically dissimilar composition from the matrix polymer, which induces phase separation upon thermal annealing into concentrated nanoparticle domains.

Abstract:

The properties of polymer–nanoparticle (NP) mixtures significantly depend on the dispersion of the NPs. Using molecular dynamics simulations, we demonstrate that, in the presence of polymer–NP attraction, the dispersion of NPs in semidilute and concentrated polymers can be stabilized by increasing the polymer concentration. A lower polymer concentration facilitates the aggregation of NPs bridged by polymer chains, as well as a further increase of the polymer–NP attraction. Evaluating the binding of NPs through shared polymer segments in an adsorption blob, we derive a linear relationship betwe

Protein replacement therapy is to-date one of the main clinical approaches to treat a wide number of diseases that are correlated to a protein dysfunction or absence.

Pharmaceutical technology strategies such as the encapsulation into a nanovector could overcome the limits of protein administration, since nanovectors can protect the payload from degradation and rapid clearance, and they can be f

Abstract:

Thermal interface material (TIM) is a major hurdle in heat flow for typical chip/heat sink assemblies. In many electronic devices, hot spots occur in areas of high activity during the device operation. These hot spots can lead to high thermal gradients, which in turn result in performance and reliability hindrances. The elevated, non-uniform power density confronted with conventional TIMs that contain a uniform layer of high thermal conductivity material for the entire chip can be extremely insufficient in many applications. In this paper, a custom engineered, Ag-nanoparticle (Ag-NP) TIM that

Abstract:

The adsorption of CO and NH₃ gases on the cubic ZrO2 (110) surface was investigated by two–dimensionally periodic slab model DFT method. The relative adsorption energies of these gases on the cubic ZrO₂ (110) surface is in order: NH₃ > CO. The adsorption energies of NH3 on the cubic ZrO₂ (110) surface are –27.62 and –25.51 kcal/mol, obtained using the PBE0 and B3LYP methods, respectively. The CO adsorption on the cubic ZrO2 (110) surface –11.39 and –9.81 kcal/mol, obtained using the PBE0 with rigid and flexible models, respectively. The geometry optimizations of zirconia nanoparticle (ZrO₂–

Abstract:

The overall goal of this project was to elucidate the role of dissolved organic matter (DOM) in soil retention, bioavailability and plant uptake of silver and cerium oxide NPs. The environmental risks of manufactured nanoparticles (NPs) are attracting increasing attention from both industrial and scientific communities. These NPs have shown to be taken-up, translocated and bio- accumulated in plant edible parts. However, very little is known about the behavior of NPs in soil-plant system as affected by dissolved organic matter (DOM). Thus DOM effect on NPs behavior is critical to assessing the
