Due to the popularity of spectroscopy and reduced budgets for undergraduate laboratories, there is great interest in low-cost, Do-It-Yourself spectrophotometers. This paper presents an implementation devised with axiomatic design principles for an affordable (sub $1000) spectrometer. This design can ...
and the methyl group in toluene-d8solvent. The UV–vis absorption spectra were measured by Hitachi U-3010 UV–vis spectrophotometer. Malid-tof-ms: MALDI measurements were performed with MALDI-TOF MS Bruker Autoflex II. Device fabrication and characterization of the OSCs...
The reusability of Zn–Mg–Al/LDH is critical for practical applications. If the adsorbent material is recycled, the adsorption process may be more cost-effective and repurposed. In order to process Zn–Mg–Al/LDH, ethanol was used in a number of cycles for both adsorption and desorption, f...
was extracted according to the methods of Zhang et al. [20]. The integrity of the extracted DNA was checked using 1% agarose gel electrophoresis, and the DNA concentration and purity were determined with a NanoDrop 2000 ultraviolet–visible (UV-vis) spectrophotometer (Thermo Scientific, Wilmington...
The ultraviolet–visible (UV–vis) transmittance spectra were recorded by a spectrophotometer (U-4100, Hitachi, Japan). The TEM images were obtained using the Talos F200X. The X-ray photoelectron spectroscopy (XPS) spectra were recorded by the ESCALAB 250Xi XPS system. The Keysight 1505A ...
UV-VIS Spectrophotometer was used to determine the efficiency of the bioadsorbents in MBD adsorption. The highest removal percentage at the most concentrated MBD were 51% and 98% for eggshells and rice husks respectively. Meanwhile the characterization of rice husks pore size and volume proves that...
to find out the concentration of dye that is adsorbed using a UV-vis spectrophotometer. From the studies, it is observed that the adsorption efficiency of pumpkin peels (PP) is higher than that of bracts of plantain flower (BP) and found to be promising alternatives for the removal of dye...
UV-Vis measurements were conducted on a Shimadzu 2550 spectrophotometer. Field emis- sion scanning electron microscopy (FSEM) studies were performed on a FEI Nova 400 NanoSEM oper- ated at 20 keV. X-ray diffraction (XRD) patterns of the samples were recorded on a D8 Advance X-ray ...
Using a Hg(II) sensor based on the aggregation of gold nanoparticles as a model system, we evaluated the performance of two portable low-cost devices that monitor the wavelength-ratiometric resonance Rayleigh scattering signal of the chemical sensor upon white-LED illumination. The first device uses...
