AI Article Synopsis

  • - A new chromatographic stationary phase made of silica-bound -butylpyrogallol[4]arene was created and analyzed using techniques like thermogravimetric analysis and scanning electron microscopy.
  • - The effectiveness of this new phase was tested with C60 and C70 fullerenes in reverse phase chromatography, showing it outperformed traditional methods in separating these molecules.
  • - The study also found that including toluene in the mobile phase helps improve the symmetry of peaks during flash column chromatography.

Article Abstract

A silica-bound -butylpyrogallol[4]arene chromatographic stationary phase was prepared and characterised by thermogravimetric analysis, scanning electron microscopy, NMR and mass spectrometry. The chromatographic performance was investigated by using C and C fullerenes in reverse phase mode via flash column and high-pressure liquid chromatography (HPLC). The resulting new stationary phase was observed to demonstrate size-selective molecular recognition as postulated from our in-silico studies. The silica-bound -butylpyrogallol[4]arene flash and HPLC stationary phases were able to separate a C- and C-fullerene mixture more effectively than an RP-C stationary phase. The presence of toluene in the mobile phase plays a significant role in achieving symmetrical peaks in flash column chromatography.

Flash column chromatographic fractionation of tree of heaven () stem and trunk bark extracts, guided by thin-layer chromatography (TLC)- assay and TLC-heated electrospray high-resolution tandem mass spectrometry (HESI-HRMS/MS), lead to the isolation of six known compounds: (9,11)-13-hydroxy-9,11-octadecadienoic acid (13-HODE, ), (10,12)-9-hydroxy-10,12-octadecadienoic acid (9-HODE, ), hexadecanedioic acid (thapsic acid, ), 16-hydroxyhexadecanoic acid (juniperic acid, ), 16-feruloyloxypalmitic acid (alpinagalanate, ), and canthin-6-one (). Their structures were elucidated by HESI-HRMS/MS and one- and two-dimensional nuclear magnetic resonance (NMR) spectroscopy. This is the first study identifying - in tree.

Linear aliphatic oligoesters derived from ε-caprolactone (CL) were synthesized by ring-opening polymerization (ROP) using terpene alcohols that have antibacterial activity as initiators (nerol, geraniol, β-citronellol and farnesol). Ammonium decamolybdate (NH)[MoO] was used as a catalyst. From previous oligoesters, monodisperse species of monomers, dimers, and trimers were isolated by flash column chromatography (FCC).

Objective: Event-related potentials (ERPs) reflect electropotential changes within specific cortical regions in response to specific events or stimuli during cognitive processes. The P300 speller is an important application of ERP-based brain-computer interfaces (BCIs), offering potential assistance to individuals with severe motor disabilities by decoding their electroencephalography (EEG) to communicate.

Methods: This study introduced a novel speller paradigm using a dynamically growing bubble (GB) visualization as the stimulus, departing from the conventional flash stimulus (TF).

Antibacterial peptides from black soldier fly larvae extract were prepared using Flash column chromatography. Three out of five fractions (F, F and F) showed antibacterial activity against Listeria monocytogenes DMST 17303 with a minimum inhibitory concentration (MIC) of 1 mM, followed by Salmonella enterica Enteritidis DMST 15679 and Escherichia coli O157:H7 DMST 12743 with a MIC ranging from 4 to 8 mM. Due to the higher yield, F and F were further analyzed on their mode of action against L.
