Aqueous-based film coating has become routine in the pharmaceutical industry. This process eliminates the use of organic solvents and thus avoids economic, environmental, and toxicological issues related to residual solvents and solvent recovery. Aqueous-based coating, however, is complex and many variables may impact the final product and its performance.

The 2-methyl-4-nitroaniline (NA) was converted into the raw material N-benzyl-2-methyl-4-nitroaniline (BNA), and the solubility of BNA in various organic solvents was calculated gravimetrically. BNA’s solubility and crystal structure make it an excellent solvent for the low-temperature solution growth method used to create single crystals of BNA with orthorhombic structure studied through single crystal analysis.

This study presents the functionalization of liquid natural rubber (LNR) by iron-mediated radical chloro-nitration over the LNR backbone, resulting in a chloro-nitro compound of liquid natural rubber (Cl-N-LNR). The chloro-nitration was prepared by a reaction of LNR with iron(III) nitrate nonahydrate and iron(III) chloride in an organic solvent. T

In this work, a bimetallic Ni-Cu-BDC metal-organic framework system was developed via solvent thermal approach with using an organic ligand recycled from waste plastic. The physical properties of Cu-BDC and bimetallic Ni-Cu-BDC were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and N2 isotherms adsorption-desorption (BET).

A major challenge for outdoor uses of methylammonium lead halide (MAPbX3) solar cells is the poor durability of the perovskite film under humidity. This instability is due to limitations of the dipping or spin coating process in producing MAPbX3 films through a direct reaction between PbI2 and methylammonium iodide (MAI) in an organic solvent. In this study, we devised an eco-friendly and cost-effective method to fabricate MAPbX3 films using an aqueous solution of Pb(NO3)2 and MAI vapour. I

Ebook "On-surface synthesis II: Proceedings of the International workshop on-surface synthesis, San Sebastián, 27–30 June 2016" is appearing as an extremely promising strategy to create organic nanoarchitectures with atomic precision. Molecular building blocks holding adequate functional groups are dosed onto surfaces that support or even drive their covalent linkage. The surface confinement and the frequent lack of solvents (most commonly being performed under vacuum conditions) create a completely new scenario fully complementary to conventional chemistry.

Ebook "Solid base catalysis (Springer series in Chemical physics, Volume 101)" is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems.
