Monolayer

Introduction and History of Langmuir Monolayers The study of Langmuir Monolayers (LMs) has greatly increased in the last few decades, which has furthered our understanding as well as appreciation for these simple yet valuable structures. This is partly due to LMs being recognized as extremely important tools in the study of complex subjects such as, but not limited to: biochemistry, biomedical research, and polymerization. Although each of these subjects is unique in its own discipline, they all

Purpose In this experiment, the different lengths of a steric acid molecules in a monolayer were measured to determine Avogadro’s number. The number of drops of stearic acid were calculated to see how much it will take to make a monolayer on the surface of water on the dish. (Goldwhite and Tikkanen) Theory The stearic acid is obtained from animal fats. The molecular formula is C17H35COOH and its composed of a hydrophilic acid group, COOH, and a hydrocarbon chain C17H35. The long hydrocarbon chain

Electronic properties of monolayer tungsten disulfide grown by chemical vapor deposition We demonstrate large monolayer tungsten disulfide (WS2) (> 200µm) by chemical vapor deposition. Photoluminescence (PL) and Raman spectroscopy provide insight into the structural and strain heterogeneity of the flakes. We observe exciton quenching at grain boundaries (GBs) that originate from the nucleation site at the center of WS2 flakes. Temperature variable transport measurements of top-gated WS2 transistors

of Submission Contact Angle Experiments on Self-Assembled Monolayers Aim The aim of this experiment was to measure the angle between a metal surface and a liquid droplet using a CCD camera and optics. This experiment also investigated how metal surfaces coated with single-molecule layers of functionalized alkanethiols and alkanethiols alter the wetting behavior and metal surface energy. Introduction Whenever a monolayer is attached to a metal surface, the wetting properties and

The trophozoite of N fowleri consists of an amoeba surrounded by a two-layer membrane. The cytoplasm contains free and bound ribosomes, as well as membrane-bound organelles. A smooth endoplasmic reticulum, a Golgi-like structure, mitochondria, vacuoles, and nucleus-containing nuclear envelope are present. Microfilaments create a supportive cytoskeleton. The N fowleri flagellate is pear-shaped. The cytoplasm has fewer vacuoles, and the components of a flagellar apparatus (flagellum, basal body, rootlet)

BC Au electrode OTFTs based on the process sequence of pentacene/OTS/AP plasma treatment/Au electrode (patterned)/APS/SiO2 was fabricated. The electrical characteristics of OTFTs with plasma treatment showed relatively high performances of devices with a low-contact resistance (Fig. 7). The current crowding effect seen in the output characteristics of the reference device can be responsible for the low performance of the device. [43,44]. In contrast, the fabricated device with 12 kV AP plasma treatment

The Lipid Bilayer is a membrane that contains protein. The lipid bilayer is a part of all cell membrane. The structural parts provide support that marks the boundaries of the cells. It is called a lipid bilayer because it has two layers of fat cells put in order on two sheets. Lipid Bilayer (Phospholipid bilayer) Assessments and Measures The Lipid Bilayer is simply a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that surround the cells as a barrier

cervical cancer. Undeniably, 2D monolayer cell culture method is one of the most popular models today in order to provide the first-hand information on the drug sensitivity on cell. In addition, this method is low costed and easy to be maintained [8]. But this culture method lacks the ability to mimic the tumour microenvironment such as the native extracellular matrix (ECM) of cancer cell [9]. In 2005, Zhang and his colleagues report that the cultured cells in monolayer can bring significantly difference

bandgap of TMD monolayers being in the visible range(400nm-700nm), they have a higher efficiency and are very promising for optoelectronic applications. MoS2 has been used to

The gentamicin resistance assay was an important tool used to investigate internalization of bacteria into eukaryotic cells. The ability to recovery intracellular bacteria and differentiate extracellular bacteria was essential for the bacteria invasion study. Gentamicin is an aminoglycoside antibiotics that was used to kill extracellular bacteria but recover viable intracellular organisms in the gentamicin resistance assay. In this assay, mammalian cells were cultured in cell culture plate under
