"Penlitian ini membahas tentang eliminasi componen metallic dan saturasi componen olefin bersama dengan eliminasi componen lain yang juga tidak di inginkan yang akan mempengaruhi laju reaksi dan kualitas produk. Solusi dari masalah ini adalah dengan mendesain sebuah trickle bed reactor berisikan Cobalt Molybdenum sebagai katalis yang dilengkapi dengan pelindung alumina dan mengandung HCL anhidrat. Reaktor ini mempunyai tinggi 3.33 m dan lebar diameter 1.5 berisikan 3080 kg katalis. Reactor yang mempunyai volume 5.874 m3 ini di desain untuk memproses 1 kg/s naphtha yang mengandung 0.03wt% sulfur, 40 ppb lead, dan 2vol% olefin.

This research discusses on removal of metallic compound and saturation of olefin with addition to other impurities removal from selected naphtha composition since it affects overall reaction rate and product quality. The solution is to design a trickle bed reactor loaded with Cobalt Molybdenum catalyst supported with alumina guard and potentially impregnated with anhydrous HCL. The reactor dimension is found to be 3.33 m in height and 1.5 in diameter packed with 3080 kg of catalyst. This 5.874 m3 reactor is designed to treat 1 kg/s naphtha which contains 0.03wt% sulphur, 40 ppb of lead and 2vol% of olefin.

"Dewasa ini, nanopartikel magnetit MNP menarik perhatian banyak peneliti dikarenakan sifatnya yang unik. Pada penelitian ini, partikel magnetit berskala nano telah berhasil disintesis dan difungsionalisasikan secara simultan melalui metode yang ramah lingkungan menggunakan ekstrak daun Graptophyllum pictum L. Griff. Pada pembentukan MNP, ekstrak daun berperan sebagai sumber basa dan capping agent. Alkaloid dalam ekstrak terhidrolisis di dalam air dan menghidroksilasi ion prekursor membentuk serbuk nanopartikel Fe3O4. Ekstrak daun juga berperan sebagai penyedia gugus fungsi hidroksil, karboksil, dan amina kepada MNP sehingga terbentuk MNP-EKDH ekstrak kasar daun dan MNP-FDH fraksi air daun .MNP-FDH dan MNP-EKDH yang terbentuk dianalisis menggunakan spektrofotometer UV-Vis, X-Ray diffraction XRD , spektroskopi Fourier transform infra red FTIR , particle size analyzer PSA , potential zeta charge PZC , scanning electron microscopy SEM , energy dispersive X-ray EDX , transmission electron microscopy TEM , dan vibrating sample magnetometry VSM .Hasil karakterisasi mengkonfirmasi terbentuknya MNP-EKDH dan MNP-FDH yang ditunjukkan melalui surface plasmon resonance pada ?max 291 dan 293 nm. Ukuran rata-rata partikel yaitu 117,7 nm dan 124,6 nm untuk MNP-EKDH dan MNP-FDH. MNP-EKDH bersifat paramagnetik sedangkan MNP-FDH bersifat superparamagnetik sehingga MNP-FDH berpotensi sebagai anticancer drug carrier.MNP-FDH dipelajari interaksinya dengan obat kanker epirubicin EPI dan didapatkan kapasitas muat yang optimum pada pH 8,0 dengan rasio berat MNP-FDH dan EPI yaitu 2:1. Interaksi MNP-FDH-EPI terjadi secara adsorpsi dan memenuhi isoterm Langmuir. Pengujian pelepasan menghasilkan kesimpulan bahwa EPI terlepas dengan baik dari MNP-FDH-EPI pada 4,5 sebesar 28,48 .

Nowaday, magnetite nanoparticles MNP attract many researchers because of their unique nature. In this study, nanoscale magnetite particles have been successfully synthesized and functionalized simultaneously through environmentally friendly methods using Graptophyllum pictum L. Griff leaf extract. In the formation of MNP, leaf extract acts as a base source and capping agent. The alkaloids in the extract are hydrolyzed in water and hydroxylate the precursor ions to form the powder of Fe3O4 nanoparticles. Leaf extract also acts as a provider of functional groups of hydroxyl, carboxyl and amine to MNP to form MNP EKDH leaf rough extract and MNP FDH leaf water fraction .MNP FDH and MNP EKDH were analyzed using UV Vis spectrometer, X Ray diffraction XRD , Fourier transform infrared FTIR spectroscopy, Particle Size Analyzer PSA , Potential Zeta Charge PZC , scanning electron microscopy SEM , energy dispersive X ray EDX , transmission electron microscopy TEM , and vibrating sample magnetometry VSM The characterization results confirm the formation of MNP EKDH and MNP FDH shown through surface plasmon resonance at max 291 and 293 nm. The mean particle size was 117.7 nm and 124.6 nm for MNP EKDH and MNP FDH. MNP EKDH is paramagnetic meanwhile MNP FDH is superparamagnetic. MNP FDH has potential as an anticancer drug carrier.The interaction between MNP FDH and epirubicin cancer drug EPI was studied. The optimum loading capacity was obtained at pH 8.0 with a weight ratio of MNP FDH and EPI of 2 1. The MNP FDH EPI interaction occurs due to adsorption and fits to Langmuir isoterm. The release test concludes that EPI is well released from MNP FDH EPI at pH 4.5 for 28.48 "

"Adi Haber's thesis summarises the use of a new entity, the corrole, to combat one of the major cardiovascular diseases, atherosclerosis. She examines the effects of three rationally designed corrole-metal complexes on some of the many variables which contribute to the development of atherosclerosis. There is a focus on both the "bad" and "good" cholesterol carriers, LDL and HDL. Adi Haber proceeds from basic findings in pure chemistry through biochemical and cell culture tests to in vivo examinations. The work in this thesis shows that corroles are highly efficient both for early and late treatment of atherosclerosis in animals. These results will pave the way for ongoing regulated preclinical studies focussed on the development of metallocorroles as potential drugs for treating cardiovascular diseases."
