一般描述
硝酸常用作有机分子硝化和氧化的主要试剂。在有机合成中，它还被用作执行氧化转化的强氧化剂。此外，硝酸还用于生产聚氨酯和聚酰胺的中间体。
应用
硝酸可用作：
- 氧化剂，使用硫酸将羧酸基接枝到CNT（碳纳米管）上，从而产生CNT-COOH。
- 在燃烧法，将溶液的pH值调整为7。它是制备混合磁铁矿-赤铁矿纳米颗粒的步骤之一。
- 作为硝化剂，与硫酸合成8-硝基-7-羟基-4-甲基香豆素和6-硝基-7-羟基-4-甲基香豆素。

Uncontrolled reactions in biological media are a main obstacle for clinical translation of V-based anti-diabetic or anti-cancer pro-drugs. We investigated the use of controlled-release pharmaceutical formulations to ameliorate this issue with a series of V(V) and (IV) complexes of anionic

The fate of NO(x) (=NO + NO(2)) is important to understand because NO(x) is a significant player in air quality determination through its role in O(3) formation. Here we show that renoxification of the urban atmosphere may occur through the

The unique physical and chemical properties of nanomaterials have led to their increased use in many industrial applications, including as a paint additive. For example, titanium dioxide (TiO2) engineered nanoparticles (ENPs) have well-established anti-UV, self-cleaning, and air purification effects. Silver

Zinc transporter-3 (ZnT3) protein is responsible for loading zinc into presynaptic vesicles and consequently controls the availability of zinc at the glutamatergic synapse. ZnT3 has been shown to decline with age and in Alzheimer's disease (AD) and is crucially involved

A poorly understood feature of the tauopathies is their very different clinical presentations. The frontotemporal lobar degeneration (FTLD) spectrum is dominated by motor and emotional/psychiatric abnormalities, whereas cognitive and memory deficits are prominent in the early stages of Alzheimer's disease
