The infiltration depth and water vapor transmission rate (WVTR) were explored in a variety of Al2O3-polymer hybrid layers as thin gas barrier films by filling the free volumes polymers subsurface region with Al2O3 using atomic layer (ALI) method. Among all, prepared Al2O3-polyethylene terephthalate (PET), Al2O3-polyimide, Al2O3-Nylon 6 nanometer ranges showed extremely low WVTR values (<10-6 g m-2 day-1) Ca dot corrosion test. Furthermore, we observed selective among two [perfluoroalkoxy...
Abstract Single‐crystal perovskite thin films were prepared by a scalable, one‐step, geometrically confined lateral crystal growth (GC‐LCG) method on patterned rolling mold and used for photovoltaic study. A record solar cell efficiency of 9.50 % under 0.1 sun with an electrode spacing 1.5 μm is attained in single‐crystal materials. Moreover, successful integration high‐source‐power‐generation interdigitated units series (1×4), parallel (4×1), combination (4 series×4 parallel) configurations...
This paper explicates the design of an ultra-thin beam splitter based on phase gradient metasurfaces using amorphous silicon hydrogenated (a-Si:H) nano cylinders for visible frequency 474 THz.The a-Si:H exhibit low losses in regime compared to standard a-Si, and small size due reduced aspect ratio other highly efficient materials such as TiO 2 GaN.In proposed design, incident wave at a single operating THz is split into two different directions according generalized Snell's law...
A bridge is a vital component of the transportation system and its piers abutments need to be properly designed for scouring avoid damage.The optimal design needs proper analysis using experimental approach as well modelling.Without having research-based knowledge such analysis, it becomes extremely difficult accurately predict effects ultimately leading severe pier damages.This research work focused on located Kabul River near Peshawar, Pakistan.The was carried out experimentally, results...
Tin antimony sulphide thin films have been synthesized as an absorber layer for solar cells. These are deposited by vacuum thermal evaporation on glass substrate at a pressure of 10-5 torr. The then annealed different temperatures in argon atmosphere. XRD analysis reveals that both and found to be polycrystalline phase. crystallinity the is significantly enhanced with increasing annealing temperatures. quantum efficiency higher visible near infrared region whereas film comparatively lower....
In this research work a high quality factor cylindrical dielectric resonator is used to determine the properties of powder mixtures. The setup based on resonant perturbation theory and it has potential quickly accurately characterize samples in quantities as small tens milligrams. loaded proposed 19,217, which operated TM01δ mode at 10.57 GHz. measured results are compared with calculated values obtained from different mixing models. worst case constant error 9.4% 9.95% been observed for...

This paper reports the synthesis of thermoresponsive colloidal nanocomposites based on CdS and poly(N‐isopropylacrylamide) (pNIPAAm). nanocrystals are prepared at room temperature from cadmium chloride sodium sulfide salts in presence an organic ligand (3‐mercaptopropionic acid) (MPA). As prepared, MPA bound stable over a month show good optical properties. The effect different ratios MPA/Cd2+ H2O/DMF resulting particle size investigated by UV‐Vis absorption measurements. Transmission...

The present study demonstrates the fabrication of a conjugated porous polymer (CPP-P2) through Pd-catalyzed Suzuki–Miyaura poly-condensation reaction. 13C cross-polarization solid-state NMR and Fourier transform infrared (FTIR) spectroscopy were used to characterize CPP-P2. Pristine nitrogen-containing CPP was explored as catalyst for oxygen reduction reaction in 0.1 M KOH aqueous alkaline media. In case CPP-P2,the occurs via four-electron transfer mechanism. An understanding at molecular...
