The equilibrium constants have been calculated using the computer program ...

Tris-1,1,1-(hydroxymethyl)ethane 1 was converted to a series of mono- and disubstituted derivatives. An indirect protocol for the differentiation of the alcohol groups was employed for the synthesis of partially and fully differentiated 1 containing a protected aldehyde unit. Complete differenti...

Paramagnetic, pentacoordinated 2,9-dimethyl- 1,10-phenanthroline adducts of bis(O, O-alkylene dithiophosphates) of nickel(II) with the general formula (where G(OH)2 = 2,3-dimethylbutane-2,3-diol, 2- methylpentane-2,4-diol and butane-2,3-diol) have been prepared by the reactions of O, O-alkylene...

Reactions of glutathione (GSH) with O,O-diorganyl dithiophosphoric acids (DTPA) were studied to develop bioactive derivatives of GSH. Effective coupling reaction of GSH with DTPA was proposed to produce the ammonium dithiophosphates (GSH–DTPA) between the NH2 group in γ-glutamyl residue of GSH...

Organogermanium derivatives of dithiophosphoric acid of general formula R4−nGe[SP(S)(OR′)2]n, where n = 1–3, R, = Me, Ph and R′ = Me, Et, have been prepared and characterized by means of 1H, 13C NMR and vibrational spectroscopy and mass spectrometry. The spectroscopic results indicate that th...

In this study, we performed a numerical simulation of the low-temperature thin-film growth of TiN layers in a plasma-assisted MOCVD reaction chamber for the purpose of eventual scale-up. Tetrakis(dimethylamino)titanium (TDMAT) or tetrakis(diethylamino)titanium (TDEAT) is commonly employed as a p...

The formation and structure of a thin film deposited using tetrakis-(dimethylamino)-titanium [Ti(N(CH3)2)4, TDMAT] as a precursor onto a Si(100)-2×1 substrate at ultrahigh vacuum (UHV) conditions was investigated by a combination of surface analytical techniques. The effects of surface temperat...

SummaryElectrochemical reduction of carbon dioxide (CO2RR) to formate provides an avenue to the synthesis of value-added carbon-based fuels and feedstocks powered using renewable electricity. Here, we hypothesized that the presence of sulfur atoms in the catalyst surface could promote undercoord...

In this work, we have studied the atomic layer deposition (ALD) of ZrO2 under various O3 dosing conditions and systematically investigated the interfacial properties of ZrO2/TiN during ALD fabrication using the CpZr(N(CH3)2)3 and O3 reactant combination. In a typical ZrO2 ALD process, the oxidat...

The attributes and limitations of chemically vapor-deposited titanium nitride films from the reaction of tetrakis-diethylamino-titanium with ammmonia and tetrakis-dimethylamino-titanium wiht ammonia are discussed. Deposited films were characterized by growth rate, resistivity, surface morphology...

The atomic layer deposition (ALD) of TiO2 from tetrakis(dimethylamino)titanium (TDMAT) and water was studied in the substrate temperature (TS) range of 120 °C to 330 °C.The effect of deposition temperatures on the resulting layer microstructure is investigated. Based on the experimental result...

Titanium nitride (TiN) can be deposited using the organometallic precursor tetrakis(dimethylamino)titanium (Ti[N(CH3)2]4) (TDMAT). Deviations from conformal TiN film growth have been observed in trench structures using TDMAT. This nonconformal deposition may be associated with readsorption and s...
