DEVELOPMENT OF PROTOCOL FOR ANALYSIS OF ACID NITRATING MIXTURE [PDF]
Technological control of nitration of organic compounds needs data about a composition of acid nitrating mixture before and after nitration. Content of water is a crucial factor for efficiency and safety of the nitration process.

Water rotational jump driven large amplitude molecular motions of nitrate ions in aqueous potassium nitrate solution [PDF]
Molecular dynamics simulations of aqueous potassium nitrate solution reveal a highly complex rotational dynamics of nitrate ions where, superimposed on the expected continuous Brownian motion, are large amplitude angular jumps that are coupled to and at least partly driven by similar large amplitude jump motions in water molecules which are associated ...

The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...

Discontinuous two step flow synthesis of m-aminoacetophenone
The continuous flow nitration of acetophenone followed by reduction of the meta isomer has been demonstrated using simple tubular reactors. Because of ease of separation of the desired isomer from the first step, both steps are made continuous, but ...

Properties of Confined Ammonium Nitrate Ionic Liquids [PDF]
Ethylammonium nitrate (EAN) and propylammonium nitrate ionic liquids confined between polar glass plates and exposed to a strong magnetic field demonstrate gradually slowing diffusivity, a process that can be reversed by removing the sample from the magnetic field.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

Nucleation kinetics in drying sodium nitrate aerosols [PDF]
A quantitative understanding of the evaporative drying kinetics and nucleation rates of aqueous based aerosol droplets is important for a wide range of applications, from atmospheric aerosols to industrial processes such as spray drying. Here, we introduce a numerical model for interpreting measurements of the evaporation rate and phase change of ...

Gd‐Induced Oxygen Vacancy Creation Activates Lattice Oxygen Oxidation for Water Electrolysis
DFT calculations shows that Gd incorporation into Fe‐doped NiO raises the O 2p band center, lowers oxygen vacancy formation energy, and thus promotes the LOM mechanism for OER. Gd and Fe co‐doped NiO nanosheets synthesized via spray combustion exhibits a low overpotential of 227 mV and maintains stable AEMWE performance for over 120 h, demonstrating ...
