Summary: A nanostructured CuO coating was fabricated as a selective solar absorber (SSA) using electrochemical deposition and thermal oxidation techniques. The coating exhibited nanowall-like structures and increased surface roughness with deposition time. The CuO coating had a well-crystalline monoclinic structure and high-purity composition. It showed high solar absorptance and infrared emissivity, as well as a lower optical band gap energy due to higher solar absorption.

Summary: The importance of detecting biochemical performance and health parameters using wearable sensors has increased. A lactic acid (LA) sensor was developed using a simple method for electrochemical detection in artificial sweat. The non-enzymatic LA sensing characteristics were evaluated using cyclic voltammetry and amperometry response with a three-electrode system. CuO nanoparticles were applied to a glassy carbon electrode (GCE) as a single-step modification using the Nafion matrix. Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV-Visible), and X-ray powder diffraction (XRD) were used to examine the CuO material used for modifying the glassy carbon electrode. The minimum detectable concentration for lactic acid was found to be 0.05 x 103 mol/l. This investigation provides an excellent approach for the specific detection of LA biomolecules for medical purposes through a non-enzymatic method.

Summary: In this study, a Tb3+-doped green-emitting phosphor AgLa(1-x)Tbx(PO3)(4) (x = 1, 3, 5, 10, 20, 30, 40, and 50 mol%) was synthesized using the flux method. Characterization analyses confirmed the monoclinic crystal structure with P2(1)/n space group. The green emission at 544 nm (D-5(4) -> F-7(5)) was observed, and the CIE chromaticity coordinates were obtained. Increasing the concentration of terbium changed the emission color of ALa((1-x))Tb(x)(PO3)(4) from blue to green. The decay curves of Tb3+ ion showed an exponential pattern regardless of the dopant concentration. The measured decay time increased from 0.97 to 1.15 ms as Tb3+ concentration increased from 3 to 30 mol%. These findings have potential applications in the field of phosphor materials and enable the development of a new generation of broadband green tunable fiber lasers, addressing the green gap.
