Synthesis of zeolite P1 from fly ash under solvent-free conditions for ammonium removal from water

Journal of Cleaner Production, 2018
In this work, zeolite P1 is synthesized from fluidized bed fly ash (FA) via a solvent-free process. The formation of zeolite P1 is investigated as a function of crystallization reaction time.

Solvent‐Free Luminous Molecular Liquids

Advanced Optical Materials, 2019
Solvent‐free luminous molecular liquids (LMLs) are a new generation of soft matter which exhibit uncharged, nonvolatile, and fluidic nature and emit intense and homogeneous luminescence in the condensed state.

Ion-Dipole-Interaction-Induced Encapsulation of Free Residual Solvent for Long-Cycle Solid-State Lithium Metal Batteries.

Journal of the American Chemical Society, 2023
Owing to high ionic conductivity and mechanical strength, poly(vinylidene fluoride) (PVDF) electrolytes have attracted increasing attention for solid-state lithium batteries, but highly reactive residual solvents severely plague cycling stability. Herein,

Solvent-free aziridination of α-nitroalkenes

Tetrahedron, 1998
Abstract NsONHCO 2 Et in the presence of CaO reacts without solvent with α-nitroalkenes to give 1-(ethoxycarbonyl)-2-nitroaziridines (62–84%). A possible involvement of an aza-Michael route is proposed on the basis of regio- and stereochemical reaction outcome, compared also with the results of thermolysis of ethyl azidoformate on the same α ...

Solvent-Free Routes to Clean Technology

Chemistry - A European Journal, 2001
A major aim for the chemical technology of the future is the avoidance of noxious and environmentally unacceptable organic solvents. In this concept article we discuss more environmentally friendly and highly selective alternatives which we have evolved for carrying out a number of important chemical conversions.

Solvent‐Free Luminescent Organic Liquids

Angewandte Chemie International Edition, 2012
Illuminating! Isolation of a π-core by covalently attached flexible hydrocarbon chains has been employed to synthesize blue-emitting oligo(p-phenylenevinylene) (OPV) liquids with tunable viscosity and optical properties. A solvent-free, stable, white-light emitting ink/paint, which can be applied onto various surfaces and even onto LEDs, was made by ...

Solvent-Free Functionalization of Carbon Nanotubes

Journal of the American Chemical Society, 2003
A fundamentally new single-walled and multiwalled carbon nanotube sidewall functionalization technique has been developed in which solvent is not required and the reaction times are greatly shortened (1 h at 60 degrees C). Exploiting the long linear dimension of the nanotube ropes by macroscopic mechanical deformation, reactive sites are generated ...

Solvent-free

Acta crystallographica. Section C, Crystal structure communications
The title compound, [Au(2)Cl(2)Fe(C(17)H(14)P)(2)], (I), contains the expected linear gold centres. The ferrocene moiety acts as a P, P'-bridging ligand, wherein the Fe atom lies on an inversion centre. The P-Au-Cl angle is 177.56 (8) degrees and bond distances Au-P and Au-Cl are 2.2261 (18) and 2.2781 (18) A, respectively.
