The mechanical properties of a 6061-T6 aluminum alloy reinforced with 20 vol.% fraction alumina particles and an unreinforced are studied over range strain rates (10-4to 6 x 105s-1) using quasistatic compression, compression torsion Kolsky Bars, high rate pressure-shear plate impact. At given the composite displays increased strength but essentially same hardening as matrix. However, stronger rate-sensitivity than does at deformation (>103s-1). is shown to be largely result imposed rather...
Perovskite and dye-sensitized solar cells are PV technologies which hold promise for application. Arguably, the biggest issue facing these is stability. The vast majority of studies have been limited to small area laboratory cells. Moisture, oxygen, UV light, thermal electrical stresses leading degradation causes. There remains a shortage stability investigations on large devices, in particular modules. At module level there exist challenges can be different from those at cell such as...
A hydrothermally synthesized mesoporous CoFe 2 O 4 (CF)/rGO nanohybrid enhances electroactive surfaces and promotes rapid electron transfer at bioelectrode–electrolyte interfaces, boosting electrocatalytic activity for adrenaline sensing.
In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising candidate for low cost energy production due cost-effective materials and fabrication processes. Arguably, DSC stability is biggest challenge making this appealing industrial exploitation. This work provides further insight into of DSCs by considering specific dye-electrolyte systems characterized Raman impedance spectroscopy analysis. particular, two ruthenium-based dyes, Z907 Ru505,...
A propitious biosensor for adrenaline (AD) detection in bovine serum albumin (BSA) real samples, which can be used diagnosis and treatment of neurodegenerative disorders, is reported here. The consists a La/ZF/rGO/ITO bioelectrode, fabricated by electrophoretic deposition zinc ferrite/reduced graphene oxide (ZF/rGO) nanohybrid followed drop casting laccase (La) enzymes. material characterization electrochemical studies revealed that the ZF/rGO enhanced electroactive surface facilitated...
Xanthine oxidase (XOx) has been physisorbed onto nanostructured nickel oxide (n-NiO, ∼41 nm), electrophoretically deposited indium-tin-oxide (ITO) glass substrate using poly-ethylene glycol via co-precipitation. The electrochemical response studies of the XOx/n-NiO/ITO bioelectrode show linear in xanthine concentration range as 10–200 μM (R2 = 0.9989), sensitivity 0.6214 μA/μM cm2, detection limit 2.989 μM, standard deviation 0.6192 μA, time 15 s with stability 100 days. observed low value...
The paper presents the measurement of optics parameters in Indus-2 synchrotron radiation source, which include betatron tune, beta function, dispersion natural chromaticity, corrected central RF frequency, momentum compaction factor, and linear coupling. Two methods were used for function measurement; a conventional quadrupole scan method using fitting orbit response matrix. A robust Levenberg-Marquardt algorithm was nonlinear least square In this paper, detailed parameter measurements are...
The mechanical behavior of polycrystalline hafnium has been investigated over a wide range strain rates (10−4–105 s−1) and temperatures (298–1023 K). Hafnium specimens were tested in compression shear using servohydraulic machines, the Kolsky bar, pressure-shear plate impact. show an unusual strain-hardening behavior, with strong but constant hardening for strains <10%, then very increasing up to ≈25%, finally decreasing until stress reaches maximum (in compression). compressive...

PDY-132 and its blends with different concentrations of poly(9,9-dioctylfluorenyl- co -3 bithiophene) F8T2 were employed as an emissive matrix for organic light-emitting devices (OLEDs).
α ‐MnO 2 /epoxy nanocomposite shows great potential for structural and tribological applications. The properties of epoxy nanocomposites depended on weight percent (wt.%) loading reinforcement material curing temperature. Therefore, the current study examines how neat epoxy’s density microhardness were affected by (0.5, 0.75, 1.0 wt. %) nano temperatures (24°C, 50°C, 80°C, 100°C, 140°C). samples created using a procedure called solution mixing method. Phase surface morphology analyzed X‐ray...
Graphical abstractAbstractWe report a sensitive, fixed-wavelength, lock-in-based optical detector built from light-emitting diode, two colour filters, photodetector, small number of discrete analogue components, and low-cost microcontroller development board.
