The history of carbon nanotubes is not entirely clear even for those in the science therefore giving proper credit to the person that invented the carbon nanotube has been the subject of several high tech debates among the scientific communities. The initial history of nanotubes started in the 1970s. A preparation of the planned carbon filaments was completed by Morinobu Endo who was earning his Ph.D. at the University of Orleans, France. This was still a highly important development in the history of carbon nanotubes, but it just wasn't the right time to be considered the first recognized...

The Rice Morphogenetic Field comprises highly complex biological, genetic, and structural mechanisms that govern the growth, form, and development of the rice plant. It encompasses the regulation of tissue organization, cell division, and environmental responses that shape plant architecture throughout both vegetative and reproductive stages.In this book, we first describe the phasic development of the rice plant, followed by a detailed analysis of the developmental pathways of major organs-leaves, roots, and spikelets-as well as specific organs and tissues. For each organ, we propose a...

This study is focused on the synthesis of two bisphosphonate derivatives, 1-hydroxy-2-(3-pyridyl) ethylidene bisphosphonic acid monosodium (sod. risedronate) and 1-hydroxy-2-(2-pyridyl) ethylidene bisphosphonic acid monosodium (HPEBP) from corresponding nitrile. The labeling of two compounds was studied with technetium-99m using two different reducing agents (SnCl2.2H2O and NaBH4) where NaBH4 gave a stable complex and high radiochemical yield more than SnCl2.2H2O. The radiochemical yield of 99mTc-risedronate and 99mTc-HPEBP were 99.2 ± 0.6 and 95.5 ± 3.5%, respectively, which more than that...
