BIOSYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE NANOPARTICLE USING FICUS RELI...Arvind Singh Heer
The objective of this study is to synthesize zinc oxide nanostructures
with the most practical ways by using Ficus Religiosa leaves extract
and characterize the nanostructures. ZnO nanoparticles were
synthesized using Zinc Nitrate (Zn(NO3)2) as a precursor and Ficus
Religiosa leaves extract solvent and distilled water were used as
medium. ZnO nanoparticles were characterized by using XRD, UVVisible
spectroscopy, EDX and SEM, FTIR. Result of EDX
characterization shows that the ZnO nanoparticles has good purity with
(Zinc content of- 72.48% and; Oxygen content of- 27.52%). XRD
result spectrum displays mainly oxygen and zinc peaks, which indicate
the crystallinity in nature as exhibited. SEM micrographs shows that
synthesized ZnO have a cubical structure. The obtained ZnO
nanoparticles are homogenous and consistent in size which corresponds to the XRD result
that exhibit good crystallinity.
This presentation is a simple explain of Bionanoimaging which introduce this area completely. You can use this PPTx File to present in your class and seminars as well. I prepare this file to present in Tabriz University of Medical Sciences when I was a MSc Medical Nanotechnology student. It will be useful for you too.
Transmission electron microscope, high resolution tem and selected area elect...Nano Encryption
The transmission electron microscope is a very powerful tool for material science. A high energy beam of electrons is shone through a very thin sample, and the interactions between the electrons and the atoms can be used to observe features such as the crystal structure and features in the structure like dislocations and grain boundaries. Chemical analysis can also be performed. TEM can be used to study the growth of layers, their composition and defects in semiconductors. High resolution can be used to analyze the quality, shape, size and density of quantum wells, wires and dots.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
