2017年7月1日 · The reagents used were of analar grade. NaNO2 is a yellowish-white crystalline solid with 68.995 g/mol molecular weight. The two-dimensional structure of NaNO2 is shown in Figure 2. To determine the role of NaNO2 concentration in the inhibition behaviour, concentrations of 0.2, 0.6 and 1 g/l were used for the corrosion tests.

2023年10月15日 · In this work, we propose a novel and highly-efficient electrolyte-assisted cathode prelithiation strategy. A small amount of soluble NaNO 2 additive (0.04 M) in carbonate-based electrolyte is demonstrated to be capable of reducing the decomposition voltage of Li 2 O 2 to as low as 4.3 V.

2009年7月20日 · Heat capacity plus respective enthalpies of fusion and of the two solid–solid transitions were measured by using the DSC Pyris 1 in the temperature range 273.15–583.15 K. Melting temperatures of pure metals (Hg, Ga, In, Sn, Pb) and enthalpy of fusion of In were used to calibrate the calorimeter.

2019年10月17日 · Sodium nitrite (NaNO2) is a cheap inorganic reagent that has wide applications in synthetic organic chemistry. The Sandmeyer reaction for transforming…

2022年9月1日 · To highlight a recent surge in new drug deaths resulting from sodium nitrite (NaNO2) toxicity in which the post mortem blood nitrite (NO2-) and nitrate (NO3) concentrations were measured. The University Hospitals of Leicester (UHL) NHS Trust post-mortem toxicology service receives samples from 27% of Her Majesty's Coroners in England and Wales ...

2-exo-Carbomethoxy-6-exo-methylbicyclo [3.3.0]oct-3-en-7-exo-yl acetate (47)Method A. Sodium nitrite (4 g) was added in small portions over 1.5 h to the amide (46) (560 mg) in acetic acid (2.5 ml) and acetic anhydride (12 ml) at 0° and the mixture kept at 0–3° for 16 hr. Cold saturated aqueous sodium acetate solution (20 ml) was added to the precipitated solid and the mixture …

Solar thermal power generation is an important method for the utilization of clean energy [1].A large amount of thermal storage material is used in concentrated solar power (CSP) systems to prolong the power generation duration [[2], [3], [4], [5]].

2009年7月20日 · Fig. 8(b) shows NEE vs power for the sintering processes, which was discussed in this study. The data for NEE calculation were extracted from BaTiO3 [136], ZrO2 [137], KH2PO4 [132,133], NaNO2 [138], MgO[139], V2O5 [140] and Bi4Ti3O13 [92,93,141]. Based on the above equation, lower NEE is an indicator of a more energy efficient technique.
