Kaolin sample from Illela local government of Sokoto state, Nigeria was used as adsorbent for removal of Copper II sulphate and to check for the effect of concentration. The collected kaolin sample was pretreated to remove debris, grinded and dried. The adsorption methods of the parameters onto the kaolin were investigated by maintaining constant amount of adsorbent, temperature and other factors except for concentration. The results from different concentrations shows that with increase in concentration of the copper solution, the more the kaolin adsorbed. From the findings, it was established that kaolin form Illela local government of Sokoto state, Nigeria can serve as an economic, safe and effective natural adsorbent for removal of copper II sulphate from wastewater.</p> H.

Therefore the application of membrane technology in the biodiesel production process can provide high-purity biodiesel quality. In this research, the process of separating and refining palm oil biodiesel does not use the washing process, but it uses membrane separation technology. The membrane used is the ceramic ultrafiltration membrane 0.02 µm. The purification process was carried out at temperature 70°C and pressure 12 Psi (0.86 bar), flow rate of 39.53 L/min, circulation time of 3 hours with a feed of 10 L. After purification, an obtained biodiesel has physical properties as follows: Purity level 97.63% mass (total ester content) and 97.02% mass (methyl ester content), kinematic viscosity at 40°C is 5.70 (cSt), density 0.86 (g/cm<sup>3</sup>), acid number 0.45 (mg KOH/g) and the saponification number 206.45 mg KOH/g. The values ​​of the physicochemical properties have met Indonesian National Standard (SNI).</p> Yoel Pasae, Yulius Salla, Lyse Bulo ##submission.copyrightStatement## Sat, 30 May 2020 00:00:00 +0000 Synthetic Strategies towards Therapeutically Relevant Tailored Macrocycles <p>The normally used synthetic approaches toward macrocyclization join full scale lactonization, macrolactamization, transition metal catalysed cross coupling, ring-closing metathesis, and click reaction, among others. Picked continuous examples of macrocyclic synthesis of natural products and druglike macrocycles with noteworthy natural significance are highlighted in each class and outline the general engineered systems for the synthesis of macrocycles. The synthesis of macrocyclic compounds incorporating natural products with differing complexities by ring closing metathesis is depicted. Twelve to huge rings that have been orchestrated in moderate to great yields and the synthesis of larger rings as a part of bi-cyclic or poly-cyclic frameworks are likewise depicted in this review.</p> Ashu Chaudhary, Subhash ., Pinki . ##submission.copyrightStatement## Sat, 30 May 2020 00:00:00 +0000
