To study the degradation of thermosetting polymers, we apply a novel method to simultaneously study the chemical structural changes and network topology: evolved gas analysis-mass spectrometry combine...
Triboelectric nanogenerators (TENG) convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, rese...
This paper describes the modification of an existing gas chromatographic (GC) method to incorporate simultaneous mass spectrometric (MSD) and flame ionization detection (FID) into the analysis of toba...
The feasibility of metabolomic fingerprinting approach based on ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UHPLC-QTOFMS) was studied to assess its abilit...
Since 1980s, several methods for the determination of lignans in food samples have been developed depending on the types of lignans and foods analysed, but mostly on flaxseed as a reference food. In t...
Database searching is the technique of choice for shotgun proteomics, and to date much research effort has been spent on improving its effectiveness. However, database searching faces a serious challe...
An accurate and rapid method, was devised for the identification and quantitation of dimethyl yellow dye in curry, based on liquid chromatography-tandem mass spectrometry interfaced with electrospray....
The structural characteristics of the components of several vacuum residues from different geological sources (Taching, Sumatra light, Iranian heavy, Arabian mix, and Murban vacuum residues) were inv...
We prepared and characterized manganese oxide magnetic nanoparticles (d =5.6 nm) and developed nanoparticle-assited laser desorption/ionization (nano-PALDI) mass spectrometry. The nanoparticles had Mn...
A high performance liquid chromatograph coupled with a tandem mass (MS/MS) detector was used for the analysis of 4-dimethylaminoazobenzene-4-sulfonyl chloride (dabsyl-Cl) derivated amino acids. Apart ...
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOFMS) is a powerful and robust tool for protein identification. We proposed a novel MALDI method (UV/FEL MALDI) bas...
A use of a free-electron laser (FEL) as the source of selective vibrational excitation was examined for infrared matrix-assisted laser desorption/ionization time of flight mass spectrometry (IR-MALDI-...
This commentary article provides short accounts of matrix-assisted laser desorption/ionization (MALDI) and time of flight mass spectrometry (TOFMS), particularly perspective views of MALDI using an in...
Matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) represents a well-accepted and reliable method for the characterization of proteins. The method has great advantages in terms...
