🔵Invitation to participate in VIRTUAL CONFERENCE ON CHEMISTRY AND ITS APPLICATIONS;[ #VCCA_2020 ]
👉the computational chemistry group started a virtual conference (VCCC) on Computational Chemistry in 2013.
✅The annual VCCC has always been in the month of Aug to mark Erwin Schrödinger day (12th Aug).
💻Kindly refer to the attached PDF files.
✅The VCCC conference has become a flagship event of the CCUoM group.
👉We were preparing for VCCC-2020.
🟢However, in view of the current World situation due to Covid-19 and travel restrictions, we have decided to extend the virtual conference, exceptionally, to all topics of chemistry. Thus VCCC-2020 will now be Virtual Conference on Chemistry and its Applications (VCCA-2020) and the website is http://sites.uom.ac.mu/vcca2020
🟢We have also decided to reduce the registration fee from 90 USD to 50 USD for participants with abstract.
🔴One can participate for free if a certificate of participation is not required.
⭕We will have the book of abstracts and the book of proceedings of full papers will be published for free by De Gruyter.
⭕Three Nobel Laureates have already confirmed their participations and they are;
👉1 Prof Ada Yonath
👉2 Prof Robert Huber
👉3 Prof Roberts Rich
🔹Kindly refer to the attached PDF for “how the conference will take place”.
🔹🔹invited to submit your abstract and invite others to submit.
🔹🔹🔹I will need your help to promote this virtual conference in your Country and network.
🔹🔹🔹🔹Remember that one does not have to travel to Mauritius and one does not have to be online for the presentation.

ABSTRACT. The current study investigated the effect of dietary supplementation with probiotics and Yucca schidigera extract on physicochemical parameters, proximate composition, mineral content and fatty acid profile of broiler breast and thigh muscles. In total, 240 one-day old broilers were randomly allocated into two dietary treatments groups: 1) Control (basal diet), 2) experimental (basal diet with two probiotics Pediococcus acidilactici and Saccharomyces cerevisiae and Yucca schidigera extract). The results showed that the pH value was higher in the

In this approach, Zn-M+3 layered double hydroxides (LDHs) with M+3 = Fe, Cr, or Al were synthesized by the co-precipitation method from the aqueous solution at a constant solution pH. The as-synthesized samples were char-acterized by XRD analysis, FTIR spectra, BET techniques and simultaneous thermogravimetric-differential scan-ning calorimetry (TGA/DSC). XRD analysis showed that Zn-Fe-CO3 had the greatest lattices parameters. BET sur-face area of Zn-Fe-CO3 was calculated as 52.24 m2.g-1 and was higher than Zn-Cr-CO3 and Zn-Al-CO3 with 46.70 and 49.99 m2.g-1, respectively. The FTIR spectra clearly confirmed the presence of carbonate anions in the struc-ture of the LDHs. Adsorption experiments for Indigo Carmine (IC), as the main model organic pollutant in this study from aqueous solution onto synthetized samples were carried out in terms of solution pH, contact time and initial dye concentration. Experimental results indicate that the capacity of dye uptake augmented rapidly within the first 15, 40, and 55 minuts for Zn-Fe-CO3, Zn-Cr-CO3 and Zn-Al-CO3 respectively and then stayed practically the same regardless of the concentration. Adsorption kinetics studies revealed that the adsorption process followed pseudo-second order kinetics model instead of a pseudo-first-order model. The adsorption isotherm data follow the Langmuir equation in which parameters are calculated. The maximum Langmuir monolayer adsorption capacities were 94.87, 21.79, and 66.71 mg.g-1 for Zn-Fe-CO3, Zn-Cr-CO3, and Zn-Al-CO3, respectively. The adsorption capaci-ties were slightly influenced by the pH variations from 5 to 10, showing the advantage of using these materials in water treatments in a wide pH range. Finally, the IC removal is proven by the presence of IC functional groups in IR spectra and thermograms. TGA/DSC of Zn-Fe-CO3 obtained after removal of IC indicate that the LDHs stabiliz-es IC and delays the combustion of adsorbed molecules. Copyright © 2020 BCREC Group. All rights reserved
