[유기화학실험] Triphenylmethanol from Benzophenone & Completion of Grignard Reaction(영문)
atoms, which have the capacity to accept two electron pairs from donor molecules to achieve a four-coordinated state, are solvated by the unshared pairs of electrons on diethyl ether : The Grignard reagent is both a strong base and a strong nucleophile. As a base it will react with all protons that are more acidic than those found on alkenes and alkanes. Thus, Grignard reagents react readily wit

[물리화학] EELS(Electron energy loss spectroscopy)
EELS (Electron energy loss spectroscopy)☞introThese days, it is important to study about the surface of the semiconductor and analyze its structure and composition. An EELS (electron energy loss spectroscopy) is one of the powerful tools for study the sample. One method to analyze the TEM data. It is the study of the vibrational motion of atoms and molecules on and near the surface by the ana

to the invention of the radio, and he predicted the use of atomic energy. Henry Ford once suggested that the period of Edisons life should be called the Age of Edison, because of the inventors many great contributions.29. Which of the following is the best title?① The life of Edison ② A variety of Edisons inventions ③ The Age of Edison ④ Edison as the greatest inventor30. Which of

to produce a strong glow, they need a catalyst to accelerate the process. The catalyst in this case is the iron in hemoglobin . If hemoglobin and the luminol mixture come in contact, the iron in the hemoglobin accelerates a reaction between the hydrogen peroxide and the luminol. In this oxidation reaction, the luminol loses nitrogen and hydrogen atoms and gains oxygen atoms, resulting in a compou

AFM(Atomic Force microscopy)Atomic Force Microscopy or Scanning Force MicroscopyAFM is one of many techniques which fall under the Scanned Probe Microscopy (SPM) family of instruments. In all of these SPM techniques a small probe (10-100 nm radius of curvature) is scanned by a piezoelectric device over a sample to produce an image of the sample surface.The first of the SPM techniques was the S

[광소재] 광자 유체 소자 Optofluidic device
to this, photons must overcome the photonic band gap energy to generate the color.Then, if we know the specific color band gap, we can make that color by control the atomic structures. Also, we can use this in ‘Information and communications technology’ by controls of total internal reflection. OptofluidicIn the micrometer scales of water, add the nano scales of coloid. Then, the coloid
