In recent time, green synthesis of metal nanoparticles is the latest developing technology and received prodigious interest because it is easy, environmentally pristine, non-fouling, antitoxic, and lowcost approach. Green route of biogenic synthesis of metal nanoparticles via microbes such as bacteria, fungi, virus, yeast and algae has the potential to deliver sustainable and enviro safe protocol. Green synthesized metal nano Read More

Extensive attempts have been made to decipher the problem associated with the solubility of drugs for maximizing bioavailability at targeted sites. More than 40% NCEs (new chemical entities) emerged through modern technology like high throughput screening, combinatorial chemistry, computer-aided drug design etc. and the drug discovery process has been dramatically accelerated. Fabrication of materials into the na Read More

Background: In recent years, the Design of Experiments (DOE) is used for removing pollutant from wastewater by nano-adsorbent. Some methods are Taguchi, Response Surface Methodology (RSM) and factorial design. The aim of this paper is to review different used methods of DOE in removing pollutant to suggest some notations to scholars. Methods: The reviewed papers were searched in Google Scholar, Scopus, and Read More

Alzheimer’s Disease (AD) is one of the most common forms of dementia affecting over 46 million people, according to AD International. Over the past few decades, there has been considerable interest in developing nanomedicines. Using nanocarriers, the therapeutic compound could be delivered to the site of action where it gets accumulated. This accumulation, therefore, reduces the required doses for therapy. Alternati Read More

Rapid growth of nanotechnology in various fields like medicine, diagnostics, biotechnology, electronics has gifted the world with products having extraordinary benefits. With increasing use of nanotechnology based products, there is a growing concern about toxicity associated with nanoparticles. Nano-size attributes unique properties to the material due to the increased surface area. But toxic effects associated with Read More

Magnetic nanofluids are defined as fluids exhibiting magnetic properties. These fluids are generated by suspending nanoparticles of magnetic nature in any base fluids. Magnetic nanofluids have been a topic of interest for researchers because of their highly useful and manipulatable properties. With the use of these fluids, heat transfer and flow characteristics can be controlled by applying external magnetic fields. Thi Read More

Background: On decreasing size down to nanoscale, the optical and electronics properties of semiconductors become tunable instead of being constant. Methods: Based on classical and quantum approach, a simple integrated theoretical model is presented without any adjustable parameter to study the size and shape effect on the refractive index, dielectric constant and bang gap of the semiconducting nanowire.

Background: The Adder is one of the most prominent building blocks in VLSI circuits and systems. Performance of such systems depends mostly on the performance of the adder cell. The scaling down of devices has been the driving force in technological advances. However, in CMOS technology performance of adder cell decreases as technology node scaled down to deep micron regime. Objective: With the growth of research, n Read More

Background: Gelatin electrospun fibers incorporated with extracted cardamom Essential Oil (EO) were developed and characterized. Materials & Methods: The gelatin solutions were evaluated in terms of conductivity, morphology, fourier transform infrared spectroscopy, and the effect of cardamom EO on the gelatin fibers. Cardamom EO showed significant antioxidant activity with IC50 value of 5 μg/mL. The extract contai Read More

Background: Atenolol is a commonly used antihypertensive drug of class III BCS category. It suffers from the problem of poor intestinal absorption or permeability thus low bioavailability. The objective of the present study was to enhance the permeability of atenolol by using a suitable technique, which is economical and devoid of using any organic solvent. Methods: The nanocrystal technology by high-pressure homoge Read More

Background: In this project, the growth and volatile metabolites profiles of Escherichia coli (E. coli ) and Staphylococcus aureus were monitored under the influence of silver base chemical, nanoparticle and ultra-highly diluted compounds. Materials and Methods: The treatments were done for 12000 life cycles using silver nanoparticles (AgNPs) as well as ultra-highly diluted Argentum nitricum (Arg-n). Volatile organic metabolites Read More

Introduction: Copolymer PBB-T with benzo[1,2-d:4,5-d']bis(thiazole) (BBT) as the accepting unit and benzodithiophene (BDT) as the donor unit is a promising candidate for highperformance non-fullerene polymer solar cells (PSCs). So far optical and dielectric constants of the PBB-T are not fully known. Method: PBB-T was synthesized and thin films of PBB-T were prepared. By using the Kramers-Kronig relations and the transmissi Read More

Background: The knowledge of parameter estimation for interatomic potentials is useful in the computation of the vibrational structure of van der Waals molecules. Methods: On the estimation of the Generalized Morse and Classical Lennard-Jones potential energy functions, complex conjugates eigenvalues may be obtained.

A bottom-up-then-up-down route is proposed to construct graphene-ZnS nanoplates (GZnS NP). Graphene-ZnS with hierarchical structure (G-ZnS HS) is first prepared by a “bottom-up” route, and then is transferred to ZnS nanoplates through an “up-down” route by annealing at low temperature. Photocatalytic activity is investigated and the formation mechanism of G-ZnS NP is proposed. This work provides an effecti Read More
