Raman spectroscopy

The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…

Parenteral formulation of an anticancer drug candidate – Tackling poor solubility 1 Introduction Cancer is the number one cause of death in Singapore , and has been on an increasing trend over the years . Hence, the search for anti-cancer drugs and better treatment regimens are widely studied but there are many challenges. One potential cancer treatment strategy is to induce apoptosis in cancer tissues by the modulation of nitric oxide production . Nitric oxide is a reactive, gaseous molecule…

the adducts formed upon the reaction of ferric HRP with nitrite by resonance Raman spectroscopy. In the absorbance spectroscopy, the spectrum of…

And Hydrogen storage in carbon nanotubes revisited written by Chang Liu,Yong Chen, Cheng-Zhang Wu,Shi-Tao Xu,Hui-Ming Cheng. These articles discusses the hydrogen storage aspect in single walled and multiwalled carbon nanotubes. The first article discusses the adsorption of hydrogen on SWCNT and MWCNT at certain…

authenticator must have. First, art authenticators must learn how to operate the lab equipment. As mentioned above, a few of the machines might include a spectrophotometer, the machines that preform the polarized light microscopy, the Raman spectroscopy, the infrared spectroscopy, and the scanning electron microscope. They…

The progress of nanotechnology has encouraged scientists to continuously pursue new electrode materials for constructing an enhanced electrochemical platform for sensing. In this study, hydrothermally-assisted reduced graphene oxide (TRGO) was synthesized using an environment friendly reducing agent in optimum time to easily exfoliate coating solution and substitute on the microelectrode. Series connected distributed sensing electrodes were fabricated and patterned with TRGO added platinum…

Abstract As one of the most popular analgesic and antipyretic, especially for pregnant women and children, acetaminophen is available over the counter in many forms. When consumed over long periods of time or in high dosages, acetaminophen has serious side effects including liver damage and other organ damages, therefore an effective quality control method of analysis. Here a method using cyclic voltammetry to analyze the concentration of acetaminophen in a liquid suspension Publix brand…

The Pistis Sophia links Mary and Jesus in a romantic way, but it also ties into the Gospel of Mary Magdalene where Peter is “hot-tempered”. The problem scholars have with this excerpt is that Mary the mother, Mary Magdalene, and Mary of Bethany were all mentioned in the Pistis Sophia and invited to these meetings with Jesus. Theorists consider Mary Magdalene and Mary of Bethany one and the same, yet there is no solid proof of that fact and the church acknowledges them as separate beings. So…

[19] and DNA typing [20], both aiming at the identification of crime victims or suspects/persons-of-interest. However, forensic science methods are beginning to far exceed such applications and often include various analytical methods, such as spectroscopy and electrochemical techniques, have seen tremendous developments. Modern developments are based on multi-disciplinary approaches involving not only physical techniques, but also computational methods. Collection and storage of samples into…

3.7.1. Effect of solvent and pH The influence of the solvent on Schiff base ligand L and its metal(II) complexes were studied. The results showed that the optimal solvent for Schiff base ligand L, Co(II), Ni(II) and Cu(II) complexes were CH3CN at λemi =320, 310, 316 and 330 nm, while the optimal solvent for Mn(II) complex was DMF λemi = 312 nm, as shown in Figure 7. The effect pH on the fluorescence intensity of Schiff base ligand L and its metal(II) complexes were investigated between…
