Collision dynamics of proton with formaldehyde: fragmentation and ionization.

The Journal of chemical physics

Wang J, Gao CZ, Calvayrac F, Zhang FS.
PMID: 24697440
J Chem Phys. 2014 Mar 28;140(12):124306. doi: 10.1063/1.4868985.

Using time-dependent density functional theory, applied to the valence electrons and coupled non-adiabatically to molecular dynamics of the ions, we study the ionization and fragmentation of formaldehyde in collision with a proton. Four different impact energies: 35 eV, 85...

Theoretical studies on gas-phase reactions of sulfuric acid catalyzed hydrolysis of formaldehyde and formaldehyde with sulfuric acid and H2SO4···H2O complex.

Appl Plant Sci. 2014 Apr 03;2(4). doi: 10.3732/apps.1400011. eCollection 2014 Apr.

PREMISE OF THE STUDY: A novel branched DNA detection technology, RNAscope in situ hybridization (ISH), originally developed for use on human clinical and animal tissues, was adapted for use in plant tissue in an attempt to overcome some of...

High-surface area mesoporous Pt/TiO₂ hollow chains for efficient formaldehyde decomposition at ambient temperature.

Journal of hazardous materials

Qi L, Cheng B, Yu J, Ho W.
PMID: 26414928
J Hazard Mater. 2016 Jan 15;301:522-30. doi: 10.1016/j.jhazmat.2015.09.026. Epub 2015 Sep 15.

Room-temperature catalytic decomposition of formaldehyde (HCHO) is considered as one of the most main methods for the removal of indoor HCHO due to its facile reaction conditions. Herein, high-surface area mesoporous Pt/TiO2 hollow chains were synthesized in high yield...

BACKGROUND: Occupational exposure to formaldehyde may decrease white blood cell counts and change blood concentration. In this study, the influences of occupational exposure to formaldehyde on the number of white blood cells and blood concentrations were studied.METHODS: This case-control...

Aqueous and Template-Free Synthesis of Meso-Macroporous Polymers for Highly Selective Capture and Conversion of Carbon Dioxide.

ChemSusChem

Huang K, Liu F, Jiang L, Dai S.
PMID: 28865092
ChemSusChem. 2017 Nov 09;10(21):4144-4149. doi: 10.1002/cssc.201701666. Epub 2017 Oct 13.

Meso-macroporous polymers possessing nitrogen functionality were innovatively synthesized through an aqueous and template-free route herein. Specifically, the polymerization of 1-(4-vinylbenzyl)-1,3,5,7-tetraazaadamantan-1-ium chloride in aqueous solution under high temperatures induces the decomposition of the hexamethylenetetramine unit into ammonia and formaldehyde molecules,...

SU-E-I-78: Neuromelanin in the Subthalamic Nucleus of Patients with Parkinson's Disease: An Electron Spin Resonance Spectroscopy Study.
