The building sector is targeting net-zero emissions through the integration of renewable energy technologies, especially for space cooling and heating applications. In this regard, use solar thermal concentrating collectors vital importance. performance these increases by using an efficient fluid such as a nanofluid due to their high conductivity. This research addresses preparation, stability ...

The global demand of the heating and cooling applications gives a larger potential to study thermal energy storage system. Phase change materials (PCM) that are used charge, store, discharge heat inferior in transfer characteristics. properties PCM can be improved by adding nanoparticles, changing orientation enclosure or both. Two-dimensional transient numerical analysis on effect Grashoff num...

BACKGROUND Multi-walled carbon nanotubes (MWCNTs) pose a possible human health risk for lung disease as a result of inhalation exposure. Mice exposed to MWCNTs develop pulmonary fibrosis. Lung macrophages engulf MWCNTs and produce pro-fibrogenic cytokines including interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and osteopontin (OPN). Atomic layer deposition (ALD) is a novel process u...

Nanoakışkanlar ile ilgili son yıllarda yapılan çalışmalar incelendiğinde termofiziksel özelliklerinin iyileştirilmesi için hibrit nanoakışkanların kullanıldığı görülmektedir. Hibrit tekli nanoakışkanlar ve temel akışkanlar (su, yağ, etilen glikol vb.) kıyaslanabilmesi en önemli adım belirlenmesidir. Bu çalışmanın amacı Al2O3-MWCNT/Saf Su nanoakışkanlarının ısıl iletkenlik, viskozite değerlerini...

We have utilized a range of manufactured or commercial nanoparticulate materials, including surrogate carbon nano-PM along with combustion-generated carbonaceous (soot) nano-PM characteristic of environmental nano- PM (both indoor and outdoor) to investigate and compare their cytotoxic response in vitro with an immortalized human epithelial (lung model) cell line (A549). These have included nan...

in this study, thermal performance of a cylindrical heat pipe is investigated numerically. three different types of water based nanofluids, namely (al2o3+water), (diamond+water) and (multi-wall carbon nano tube (mwcnt) +water) have been used. the influence of using the simple nanofluids and mwcnt nanofluid on the heat pipe characteristics such as liquid velocity, pressure profile, temperature p...

Objective: Periodontal disease is an essential phenomenon in human health. Oral pathogens can cause severe break which may show the way to serious issues like chronic obstructive pulmonary and cardiovascular diseases. Therefore, aim of this study evaluate antibacterial effect a series nanoparticles on oral pathogens.Methods: In study, activity such as MWCNT, CuO2, CaCO3, SiO2, Al2O3, MgO ZrO2 a...

Although carbon fiber-reinforced polymer (CFRP) composites have excellent intrinsic mechanical properties, they are vulnerable to impact loads because of their weak inter-laminar fracture toughness, which results in delamination damage. This study presents a novel hybrid nanofiller combination multi-walled nanotubes (MWCNT) and alumina nanoparticles (Al2O3) determine improvements the resistance...
