1 102.Cnf-1096 Resistance Switching in Chalcogenides Memory Cell Ag/Ag-Ge-S structures Memeristive based memory is explored to be the future memory cell devices that can replace the identical MOS memory and to overcome the major problems of these memory devices. Nonvolatile (NV) memory cell can be fabricated depending on the phenomena of phase change memory (PCM) of chalcogenide materials. In this research an Ag-Ge-S/Ag structure memory cell was fabricated as a nonvolatile memory cell using vacuum thermal evaporation technique. The properties of these memory chalcogenides materials has been modified by controlling the evaporation parameters such as pressure, thickness and temperature or other external parameters, namely the applied voltage polarity. It is found the on state resistance of about 18 KΩ and an off state resistance of about 18.1011 Ω. The cell has very small write current of about (45 pA) which shows a great promise for using as extremely low power. GMC-ElecEng 2020 Claim
2 47.Cnf-1135 Image based microfluidic mixing evaluation technique Micromixers are considered an integral part in biomedical microfluidic applications because of important chemical and biological processes that require rapid and efficient mixing. In this work, flow regimes in throttle-T and square wave type micromixers are studied. The dependence of mixing efficiency on the geometry design is examined. Passive mixing methods with different flow rates at the inlets are studied experimentally using an imaging based technique. Moreover, a finite element model is used in order to study the mixing process of species in 500 µm and 400 µm - wide throttle and square wave microchannels, respectively. The results illustrated the effects of both flow rate and channel geometry on the mixing efficiency. Experimental studies at different flow rates are reported showing the same mixing tendency.

3 51.Cnf-1117 Streamline development of propellent-free topical pharmaceutical foam: Efficient quality by design strategy of a potential sunscreen foam Catching up with a recent interest in developing green pharmaceutical products, a key challenge is encountering formulation scientists to find proper ingredients, approach or dispensing tools in a reasonable time due to manufacturing variability. Therefore, this work is established to produce green propellent-free topical pharmaceutical preparation and thus environmentally friendly, through utilization of the concept of quality by design (QbD) to eliminate or reduce the source of variability. A foam dosage form with ingredients suitable for potential sunscreen application was developed. Formulation ingredients were based on local Jordanian virgin olive oil. Twenty formulae were screened under the theme of QbD. One formulation successfully combined in relatively stable water in oil emulsion, whereby foam generation was achieved through specialized dispensing tool. Textural characteristics were evaluated by human panel (30) and found favourably acceptable for this formulation. Physicochemical characteristics of the investigated and optimized formulae were confirmed through light microscopy, viscosity and spectrophotochemical measurements. Sun protection factor (SPF) was determined as 12.1±0.6 (n=3); indicating potential sunscreen applications for almost two hours in the daytime. Critical quality attributes were determined throughout the development process and risk assessment measurements were estimated thereof. Such an outcome that will help to create preliminary predictive model for scalable industrial screening production of this green pharmaceutical topical preparation with local sourcing of generally regarded safe materials (GRAS).
