Adamantine derivatives

A range of experimental methods, XES, XPS and AES were employed to examine the electron states of an adamantine derivative (CiqH CFUU), pyrene... 

Diamondoids show unique properties due to their exceptional atomic arrangements. Adamantane consists of cyclohexane rings in chair conformation. The name adamantine is derived from the Greek word for diamond since its chemical structure is like the three-dimensional diamond subunit, as shown in Fig. 5.

Tin is a relatively scarce element with an average abundance in the Earth s crust of about two parts per million (ppm) compared with 94 ppm for zinc, 63 ppm for copper, and 12 ppm for lead. Tin is produced from lode (hard-rock) deposits and placer deposits derived from the lodes. The tin mineral cassiterite (Sn02) is the source of most tin production. A notable exception is the complex tin sulfide minerals in the subvolcanic or tin-silver lode deposits in Bolivia. Cassiterite has a high specific gravity (6.8 to 7.1), a Moh s scale hardness of 6 to 7, and is usually a dark brown or black color with an adamantine luster.

Solid hydrophobic substances are represented mostly by high molecular organic substances. They include such organic substance decomposition products as peat, humus, sapropel, and also asphalt-resinous substances and their derivatives, which along with solid hydrocarbons (octadecane, naphthalene, biphenyl, phenantrene, perylene, adamantine, etc.) compose bitumens. 

Inorganic ions, drugs, nucleic acids, proteins, and even cells are successful examples of imprinting. In this way, affinity sensors, receptor sensors, and catalytic sensors based on MIPs have been explored. For affinity sensors, immunosensor-like devices were prepared by a 2D MIP technique with molecular imprinting on chemisorbed alkanethiol SAMs then after necessary procedures, vitamins Ki, K2, E, cholesterol, and adamantine could be detected by the strong electrochemical signals yielded. The sensors for nucleic acids, cholesterol, and catechol derivatives can be fabricated first by their adsorption as a template on the ITO surface and then by the treatment of the electrode with adsorbed template using trimethyl chlorosilane from the gas phase.
