We report highly stable zero-dimensional (CH 3 NH 3 ) 3 Bi 2 I 9 photovoltaic cells which demonstrate a 33% increase in performance after 2 years when hybridized with silicon nanocrystals (SiNCs).
In this study, a conducting polymer PEDOT: PSS counter electrode is introduced in a typical DSSC (Dye Sensitized Solar Cell) with N719 dye adsorbed TiO2 nanoparticle coated FTO (Flourine doped Tin Oxide) glass as photo anode and an iodide-triiodide system as electrolyte. Counter electrode modification is done by intro…
Computational models are very important in understanding the nature of interactions in chemical systems from which important geometry parameters for various organic compounds can be extracted. This study explores computationally the geometry parameters of selected volatile organic compounds from the co-pyrolysis of Cr…
Stainless steel alloy SS-304 is widely used in many engineering applications primarily for its excellent corrosion resistance, ease of fabrication and aesthetic appeal. Many kitchen appliances are made from SS-304 alloy because of its durability, ease of cleaning and beautiful finish. However, over the years of contin…
Oxygen vacancies were selectively created on PrCe/SiO 2 for efficient transformation of a furfural–acetone adduct into a functionalized 1,3-diene.
The goal of the work is to study and analyze the main ballistic characteristics of a bullet and buckshot after a ricochet. A ballistic experiment on the formation of gunshot injuries when fired from a 12-gauge hunting gun with a subsequent ricochet of a bullet and buckshot was carried out. The distinctive features of…
We have successfully demonstrated a stretchable gas sensor with enhanced sensitivity to hydrogen based on crumpled graphene structures. Compared with the state-of-art technologies, three distinctive advancements have been achieved: (1) enhanced sensitivity to hydrogen based on the crumpled graphene at room temperature…
Transaminase activity was determined by time-lapse imaging using a colourimetric reaction and image analysis. A correlation between the benzaldehyde conversion and relative luminance was determined, allowing the identification of the most promising biocatalysts, the determination of kinetic parameters, and the assessm…
The plant cell wall is a complicated network that is mainly constituted of polysaccharides, such as cellulose, hemicellulose and pectin. Many noncellulosic polysaccharides are further acetylated, which confers these polymers flexible physicochemical properties. Due to the significance of cell wall in plant growth and…
This paper addresses the period-signal tracking problem for a class of nonparametric uncertain systems with several periodic time-varying disturbances, where there is no common multiple among the period lengths of reference signal and disturbances, or the common multiple is difficult to be obtained even if it exists.…
In this paper the combined effect of alumina and graphene reinforced with aluminum matrix by using stir casting methodology, was evaluated. Hybrid metal matrix composites gives combined results effect of different reinforced aspects when combined with ductile matrix appearance. Both alumina and graphene we are varied…
The high-content bipolar phosphor (ppy) 2 Ir(dipba) can dominate the EL process and the recombination zone is almost broadened as wide as the whole EML in D4, leading to remarkably higher efficiency level of D4 than that of D2 based on (ppy) 2 Ir(acac).
Enhanced-fluidity, reversed-phase liquid chromatography was developed using custom instrumentation for separation and characterization of intact KRas proteins and tryptic peptides. The KRas, HRas and NRas function as GDP-GTP regulated binary switches in many signalling pathways, and mutations in Ras proteins are frequ…
In this study, to synthesize various glasses for the system (20-x) Li 2 CO 3 -10 ZnO -5Al 2 O 3 -65H 3 BO 3 -xV 2 O 5 with (x = 0, 0.2, 0.4, 0.6 and 0.8 mol%) the melt-quenching technique was used. Fourier transform infrared (FT-IR), Electron paramagnetic resonance (EPR) and Ultraviolet-visible (UV-Vis) spectroscopy c…

The electrodeposition of invar Fe-Ni alloy with low thermal expansion was performed at 100-5000 A·m–2 and 105 C·m–2 in agitated Watt’s solution containing NiSO4, NiCl2, FeSO4, C3H4O4, C7H4NNaO3S and H3BO3 at 50ºC. With increasing the concentration of malonic acid, the Ni content in deposits decreased at higher current…
This paper tackles the problem of industrial waste heat recovery through an unexploited heat transfer mechanism: thermal radiation. Energy intensive industries have a considerable potential of unused radiant heat, which cannot be recovered through existing methods. That potential energy is quantified for the main iden…
In this study, a low-cost gas-sensing device that integrates a zinc-oxide (ZnO)-based gas sensor with a microplasma generation unit is presented. By the proper connection of different sets of electrodes to the desired power sources or the measurement circuit, the device can be operated in the microplasma mode (MPM) or…
Natural radionuclides content in granite from eight functional quarries in Osun State, Southwestern Nigeria was assessed. Eighty granite samples comprise ¾ inches. ½ inch and stone-dust were collected from Wolid, Slava, Ayofe, Espro, Ife/Modakeke, Krystal Vountein, Clario and Omidiran quarries in the State. Measuremen…
-CEA)) annealed at 60 °C were 3.75 V, 756.5 nA, and 716.9 nW, respectively. Thus, the composites showed 13.4% and 11.3% improvements in the maximum output power compared with that of PNG-2D & 3D(RT) dried at room temperature, respectively. These results indicated 27.4% and 7.8% improvements, respectively, compared wit…
