  • 4-Np Synthesis Lab Report

    Abstract A spontaneous, one-pot strategy for the room temperature biosynthesis of gold nanoparticles (AuNPs) using Cocos Nucifera Linn (coconut palm) coir extract is described. The formation of AuNPs was observed within 30s of reaction time between the metal precursor and coir extract. The bioextract acted as both reducing agent and a stabilizer. The influence of various experimental parameters such as % volume fraction of coir extract, concentration of metal precursor, contact time and solution…

  • Drug Encapsulation Essay

    3.3.9. Encapsulation efficiency of drug loaded NPs The encapsulation efficiency (EE) was determined by weighing the amount of unloaded drug recovered from lyophilization of the supernatant obtained after centrifugation of NPs. The drug encapsulation efficiency was calculated according to the following equation: Encapsulation efficiency (%) = (Winitial/Wfree)/Winitial *100%. Where, Winitial and Wfree are the weight of initial drug and the weight of free drug determined in the supernatant after…

  • Extraction Of Alkali From Banana Peels Lab Report

    Extraction of alkali from banana peels is known to depend on such parameters as ashing temperature, ashing time, soaking time and particle size of the ashed sample, soil type and variety. Alkali was extracted from three Nigerian grown banana peels namely: Saaro, Oloosun and Paranta for the purpose of determining the concentration of the extracted alkali. The concentration of the extracted alkali ranged from 0.02 to 0.10mol/dm3. The three varieties of the banana peels gave a maximum concentration…

  • Heckel Equation Of The Densification Of Faction

    a) Heckel equation In 1961, Heckel proposed the most widely used equation describing pharmaceutical powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],.…

  • Hazelnut Kernel Oil Case Study

    Metin GUMUS et al.,[1]. In this study, hazelnut (Corylus avellana L.) kernel oil was tested and studied as an alternative fuel in diesel engines. The hazelnut kernel oil is made to undergo transesterfication process for reducing the viscosity of the oil. The processed hazelnut kernel oil possesses all the properties of biodiesel used in the diesel engine. The suitable transesterification reaction conditions for hazelnut kernel oil are volumetric ratio of the reactants in the ratio 1:5, reaction…

  • Case Study: Preparation Of Microemulsion

    3. Preparation of microemulsion:- Microemulsion was prepared by dispersing required quantity of Aripiprazole (15 mg/ml) in appropriate quantity of oil. The mixture was homogenized and to it, accurately weighed quantity of surfactant: cosurfactant blends was added in small portion with stirring. The blends were mixed thoroughly using magnetic stirrer and to it add dropwise double distilled water with continuous stirring around 10 min. compositions of ARP microemulsion shows in Table 1. 4.…

  • Peanut Shell Case Study

    Witek-Krowiak et al., (2010) researched on the use of peanut shell to remove heavy metals from water solution. Cu (II) and Cr (III) ions were the heavy metals in this research, using Langmuir, Freundlich, Redlich–Peterson and Sips models to examine data gotten from the tests. The preparation of the bio sorbent material (peanut shell) was prepared by washing with pipe and refined water for about 1-2hrs to remove dirt and colour, the washed peanut shells were dried in an oven for a day then mashed…

  • XRD Analysis Of Cumnox

    The SEM result was also in good agreement of XRD analysis. The average particle size of CuMnRC1, CuMnRC2 and CuMnRC3 catalyst was 0.675µm, 3.127µm and 7.435µm respectively. The particles of CuMnRC1 catalyst was least agglomerated, highly porous, high surface area and uniformly distributed. The choice of different precipitant in the CuMnOx catalysts leads to the change of the surface distribution of Cu, Mn and O elements, which might be related to the CO oxidation catalytic performance of the…
