This paper presents the <i>first</i> parameterized, SPICE-compatible compact model of a Graphene Nano-Ribbon Field-Effect Transistor (GNRFET) with doped reservoirs that also supports process variation. The current and charge models closely match numerical TCAD simulations. In addition, process variation in transistor dimension, edge roughness, and doping(More)
The content of main flavonoids from Rhododendron adamsii R. leaves and stems was determined quantitatively using HPLC. It was found that myricetin and quercetin dominated the identified compounds (myricetin, quercetin, dihydroquercetin, rutin) in leaves; dihydroquercetin, in stems (1.1, 1.0, and 2.5 mass% of raw material, respectively). Dihydroquercetin and(More)
This paper presents the first parameterized, SPICEcompatible compact model of a Graphene Nano-Ribbon FieldEffect Transistor (GNRFET) with doped reservoirs, also known as MOS-type GNRFET. The current and charge models closely match numerical TCAD simulations. In addition, process variation in transistor dimension, line edge roughness, and doping level in the(More)
A series of secondary amines combining monoterpenoid and aminoadamantane moieties have been synthesized. Their cytotoxic activity against human cancer cells CEM-13, MT-4, and U-937 has been studied for the first time. Most of the obtained compounds exhibited a significant cytotoxic activity with the median cytotoxic dose (CTD50) ranging from 6 to 84 µM. The(More)
2-(3(4)-Hydroxy-4(3)-methoxyphenyl)-4,7-dimethyl-3,4,4a,5,8,8a-hexahydro-2H-chromene-4,8-diols were found recently to possess high analgesic activity and low acute toxicity. Stereoisomers of these compounds with high optical purity were synthesized from (+)- and (−)-α-pinenes for the first time in this work. The structure of (4S)-4b isomer was confirmed by(More)
Cardioprotective effect of resveratrol and resveratroloside was determined in ischemia-reperfusion experiments on rats. It was found that single intraperitoneal administration of any compound (10 mg/kg) followed by 30-min ischemia and 120-min reperfusion resulted in statistically significant decrease of myocardial infarct area (55.0±4.0% for control group;(More)
A fast, selective and sensitive procedure for quantitation of the camphor-based anti-influenza agent camphecene in whole rat blood was developed and validated using dried blood spots and LC-MS/MS. The method was validated according to recommendations of the FDA and EMA in terms of selectivity, linearity, accuracy, precision, recovery, matrix factor,(More)
Siberian pine (Pinus sibirica), also known as Siberian cedar pine and Siberian cedar, is an important plant that has been long used as a source of natural compounds and materials (wood, needles, soft resin, turpentine, colophony). Its chemical composition has been studied well enough; however, to our surprise, no articles that compile the phytochemical data(More)
Chemical compositions of essential oils (EO) from leaves and stems of Rhododendron adamsii, R. aureum, and R. dauricum were studied by GC/MS. The analysis demonstrated that the EO of these plants contained mainly mono-and diterpene hydrocarbons. A large amount of alkanes was also found in the EO of R. aureum.
