A new method using fluorescence was developed to detect Hg 2+ ions in water. This relied on the reaction between NH 2 ‐MIL‐53(Al) and 5‐bromo‐2‐hydroxyacetophenone. The carefully fine‐tuned for optimal conditions analytical parameters like pH levels, nanosensor quantity, detection limits. It showed great linearity detecting range of 0.0–3.0 ppm (0.0–1.50 × 10 −5 M), with a very low limit 1.65 −2 (8.23 −8 M). We tested how well can distinguish different substances by investigating whether...

Nowadays majority industries are shifting towards green manufacturing with application lean tools such as implementation Takt Time. The proposed study carried...

Metal-organic frameworks (MOFs) are particularly interesting within the adsorption of organic contaminants.This research investigated acid red 57 (AR57) and methylene blue (MB) in aqueous medium using NH 2 -MIL-101(Cr) as adsorbent.MOF were described by X-ray diffraction (XRD), N adsorption-desorption (BET), Scanning Electron Microscopy (SEM) Fourier transform infrared spectroscopy (FTIR).The fabricated MOF has 1467.75 m /g huge surface area pore volume 2.15 cm 3 which classified...

&lt;p&gt; A Reconfigurable Intelligent Surface (RIS) panel comprises many independent Reflective Elements (REs). One possible way to implement an RIS is use a binary passive load impedance connected antenna element achieve the modulation of reflected radio waves. Each RE reflects incoming waves (incident signal) by using on/off between two loads and adjusting its phase Phase Shifter (PS). However, this process reduces amplitude output signal less than unity. Therefore, recent works have...
