Results of LIB leaching with PP using RSM

The RSM method was employed to optimize the leaching parameters of the LIB cathode, in the presence of PP, to enhance the recovery of Ni, Co, Mn, and Li. Table 3 presents the recovery of Ni, Co, Mn, and…

Fourier transform Infrared spectra (FTIR) of modification AFW

Figure 1 shows the Fourier Transform Infrared (FTIR) spectra of spectrum of all unmodified AFW as well as the modified AFW. The distinct peak at 2241 cm⁻¹ corresponds to the nitrile…

Characterization of ASDs

FT-IR, XRD, and UV spectroscopies were utilized to analyze the physical and chemical characteristics of the prepared ASDs of ERL. This study preferred a 10:90 (drug: polymer) weight ratio depending upon the stability and…

Characterization of the catalysts

X-ray diffraction (XRD)

The catalyst samples were examined using X-ray diffraction (XRD) within the range 5°>2 > θ90° to determine their crystalline structure, as shown in Fig. 1.

The X-ray diffractogram of…

Characterization

Figure 1 shows the SEM surface images for S1 (a) and S2 (b). Both surfaces can be termed rough random-corrugated, however, the S2 surface is rougher which comes from alkaline treatment where some deprivation of cellulose,…

Toxic gas emissions during electrical discharge machining (EDM) significantly affect operator health and the environment, making their reduction a critical engineering objective. This study investigates the primary toxic gases emitted during EDM…

All melting points are uncorrected and were determined using a Griffin and George melting point apparatus (Griffin & George Ltd., Wembley, Middlesex, UK). Infrared (IR) spectra were recorded at the Faculty of Science, Ain Shams University, using…

Have you ever been asked to deliver a presentation at a conference or to colleagues, but turned the opportunity down as you were nervous about it? These opportunities seem daunting but they are a fantastic way to boost your profile and to…

Following the devastating missile attack on the Weizmann Institute of Science in Israel by Iran on 15 June that destroyed around 45 labs, the dean of the faculty of chemistry is adamant that they will build it back better than ever.

The UK’s Advanced Research and Invention Agency (Aria) is looking for a new leader after current chief executive, Ilan Gur, announced his intention to step down. Gur has led the agency since it was launched three years ago.

Aria is…
