Photovoltaic modules are impacted by overheating, which degrades their conversion efficiency and shortens lifespan. This work attempts to study the cooling potential for a hybrid photovoltaic/thermal (PV/T) system employing CuO Fe2O3 nanofluids with 0.2% 0.3% volume fractions (φ), circulated in heat exchanger attached at rear side of PV module lower temperature cells improve its energy exergy efficiencies. Consequently, 2D numerical model was analysed given balance across PV/T layers, is...
Nanotube assemblies constrained to predetermined geometric patterns form the topic of research presented here (see also cover). It is demonstrated that microcontact printing can be used pattern silicon wafers with catalysts upon which multiwalled carbon nanotubes are selectively grown. The Figure a scanning electron microscopy image surface thus patterned nanotubes.
The feasibility of the application Photo-Fenton process in treatment aqueous solution contaminated by Tylosin antibiotic was evaluated. Response Surface Methodology (RSM) based on Central Composite Design (CCD) used to evaluate and optimize effect hydrogen peroxide, ferrous ion concentration initial pH as independent variables total organic carbon (TOC) removal response function. interaction effects optimal parameters were obtained using MODDE software. significance their interactions tested...
Recently, photovoltaic technology applications have occupied a wide range in electric generation. The temperature rising higher than the operating permissible is weak point facing this technology, which significantly influences performance of cells. Using nanofluids as coolant (PV) modules an effective method, circulating heat exchanger attached to backside PV module absorb excess and enhance module. current work investigates using zirconium oxide (ZrO 2) nanofluid at different volume...
Overheating of photovoltaic (PV) cell is one the most common issues that cause degradation their function and reduce conversion efficiency.

In the context of recycling and reusing textile wastewater, quest for a membrane possessing superior efficiency has garnered considerable attention. This research endeavors to advance this objective by introducing novel asymmetric ultrafiltration constructed from PVDF (Polyvinylidene Fluoride) modified with MXene through bulk modification, thereby augmenting its resistance fouling wastewater treatment applications. The investigation employed comprehensive array characterization techniques....
Photoelectrochemical reduction of CO<sub>2</sub>to form useful chemicals is an increasingly studied avenue for harnessing and storing solar energy.
The temperature rising of the photovoltaic (PV) modules is a major issue leading to reduction in their conversion efficiency and low output power. Therefore, removing heat from PV module necessary permanently work improve electrical power output.

It was found that PPSU membrane fabricated from 0.1...
Single wall carbon nanotubes (SWNT) were functionalized via addition of radicals, which generated by thermal decomposition diacyl and dibenzoyl peroxides. Reaction products investigated with TEM, Raman scattering, TGA, UV−Visible spectroscopy, FTIR, 1H NMR. In spectra SWNT materials one the radial breathing modes a maximum at 260 cm-1 diminished completely. At same time, intensity ratio between G- D-bands decreased in comparison to that spectrum raw material. From TGA measurements we...
