Calorimetry

AC conductivity: Figure 4.19(a) shows the frequency dependent electrical conductivity of PCL5 electrolyte. The result shows that AC conductivity changes with temperature. The AC conductivity of the PEO/CoCl2 electrolyte increases with temperature is given in Table 4.4, which is the common characteristic of disordered materials. An increase in ac conductivity with frequency and temperature indicates charge transported by hopping through the defect sites along the polymer chain [70]. Also the…

Introduction The purpose of this lab is to test for the most efficient way to transfer heat energy from the chip to the water beaker. The heat transfer was coming from burning a baked lay and through our calorimeter heat energy was pushed out. Our experiment was taken one step further to continue to modify and build a better calorimeter. Overall the purpose was to find the best way for energy to be captured. Literature Review Anything around us is generally matter. Everything we touch,…

process, in the presence of Sodium hydroxide catalyst and methanol batch transesterfication is applied to sunflower oil for the production of biodiesel. The biodiesel was characterized and then conducted using Nuclear Magnetic Resonance (NMR), bomb calorimetry, sulphur content tests and Gas Chromatography (GC) and acidity and flash point…

1. I successfully completed N-glycan, site specific-glycopeptides, and SEC (size-exclusion chromatography) analysis on several big batches of M710 RPP and process development samples in a timely manner. I am very dedicated to the tests I performed. The process of each analysis is complicated and often requires several days of lab-intensive work, and it is common to receive multiple tests at the same time. In order to meet the tight timeline, I rationally prioritize my tests, and plan my time to…

endothermic, which have a negative change in enthalpy. Since the energy released is usually heat, keeping track of the heat flow in reactions will help determine the change in enthalpy of a reaction. Observing the measurement of heat changes is known as calorimetry; hence, in this lab a calorimeter was used to measure the changes in enthalpy. A calorimeter is well-designed when it is well insulated from the environment so there could be minimal to no heat change between the system and…

The thermal value is the amount of heat generated by completely burning of one kilogram of waste and is measured by experimental calorimetry or calorimetric bombs, and is used in calculation of energy recovery systems. The thermal value of municipal waste is a function of the waste components and decreases when moisture is present. The thermal value of municipal waste is between 800…

4A.3 Results and discussion 4A.3.1 Selection of Excipients Drug loaded Solid Lipid Nanoparticles(D-SLN)were successfully formulated using two different lipidsand surfactants and physicochemical parameters of the same have been assessed. Tamoxifen citrate is proven adjuvant therapy of choice for postmenopausal women, primary therapy for breast cancer in elderly women as well as preventive therapy for most vulnerable women. The extensive administration of Tamoxifen citrate daily for a period of…

ABSTRACT Dex-Ibuprofen–polyethylene glycol (PEG) conjugates (PEG-dex-Ibu) were organized and their prospective as a prolonged release method was investigated. PEG-Dex-Ibuprofen conjugates were synthesized as of Ibuprofen and PEG with 4000 Da molecular weights by esterification in the incidence of DCC and DMAP. The PEG-dex-Ibu conjugates were characterized by FT-IR, 1H NMR, and DSC analysis. The solubility revise in aqueous system showed an improvement within the solubility of conjugates. The…

PRE FORMULATION STUDY: Pre formulation testing was an investigation of physical and chemical properties of a drug substance alone and when combined with excipients. It was the first step in the rational development of dosage forms. Class: -Pre formulation study can divide into two subclasses: API characterization, Compatibility study Active pharmaceutical ingredient (API) characterization:- Organoleptic evaluation:-These are preliminary characteristics of any substance which is useful in…

Fig: Schematic representation of LHC and it's detectors The primary objective of LHC is to answer the following questions: 1. Why some particles are heavier than others? If the Higgs mechanism is valid? 2. If the super-symmetry theory is valid? If yes then if super-symmetric particles exist? 3. If the concept of dark matter and dark energy correct? 4. Why our universe is made up of matter only? 5. What was the state of matter in the early universe? 6. What will be the properties…
