A series of novel bioproducts obtained from natural sources (marine, animal, vegetal) have been discovered and characterized for the prevention and treatment of Neuro Degenerative Disorders (NDDs) and vascular pathology. Lipofuscins (LFs) are a new class of lipoproteins derived from the muscle of different fish species. Examples of LPs obtained from biomarine sources by means of nondenaturing b...

we have performed a density functional theory investigation on the structural and electronic properties of pristine and nitrogen-doped tio2 anatase nanoparticles as the adsorbents for removal and degradation of hydrazine molecules in the environment. we have presented the most stable adsorption configurations and examined the interaction of hydrazine molecule with these doped and undoped nanopa...

The mechanical behavior of TiO2 nanoparticle-reinforced resin-based dental composites was characterized in this work using a three-dimensional nanoscale representative volume element. The impacts of nanoparticle volume fraction, aspect ratio, stiffness, and interphase zone between the resin matrix and nanoparticle on the bulk properties of the composite were characterized. Results clearly demon...

The increasing use of nanomaterials raises concerns about the long-term effects of chronic nanoparticle exposure on human health. However, nanoparticle exposure is difficult to evaluate non-invasively using current measurement techniques. Here we show that the skin is an important site of nanoparticle accumulation following systemic administration. Mice injected with high doses of gold nanopart...

An eco-friendly green mediated synthesis of inorganic nanoparticle is a fast growing research in the limb of nanotechnology. This study reports the synthesis of silver Nanoparticle by using commercially available spice Elettaria cardamomom without the use of toxic chemicals. Visually, the formation of silver Nanoparticle was confirmed by observing the colour changes from pale yellow to dark bro...

This study has demonstrated, for the first time, a simple, fast and flexible microwave processing method simultaneous preparation of bio-products (bio-oil, bio-gas biochar) using methodology that avoids any form catalyst or chemical activation. The dielectric properties biomass physicochemical characterisation such as TGA, elemental proximate analysis, XRD, SEM/EDX textural properties, showed 8...

The utilization of synthetic additives (vitamins, proteins, and pigments) in broiler chicks’ feeds may cause problems the future, such as competitive availability, extra productive induced costs, human health risks relayed on sole ingredients commonly used animal food feeds. A total 320-day-old chicks were randomly assigned to eight experimental groups (a four × two factorial design), receiving...

The convergence of biofabrication with nanotechnology is largely unexplored but enables geometrical control of cell-biomaterial arrangement combined with controlled drug delivery and release. As a step towards integration of these two fields of research, this study demonstrates that modulation of electrostatic nanoparticle-polymer and nanoparticle-nanoparticle interactions can be used for tunin...

This paper proposes a high precision method for nanoparticle counting and sizing using a microring resonator-waveguide system that contains a flow-through nanopore. Theoretical analysis is carried out based on the coupled-mode theory, showing that when the nanoparticle passes the nanopore a temporal pulse signal can be detected and that the peak amplitude depends linearly on the nanoparticle vo...
