Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

On the theory of ion transfer rates across the interface of two immiscible liquids [PDF]

open access: yes, 2000
Ion transfer across the interface of two immiscible liquids involves a mechanism for initiating desolvation from the first liquid, A, and concerted solvation by the second, B.

Progress in Surface‐Enhanced Raman Scattering‐Based Volatile Organic Compounds Detection: Materials, Application, and Prospects

open access: yesRare Metals, EarlyView.
ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

f‐Block Element‐Based MOF Thin Films: A Platform for Luminescence, Sensing, and Energy Applications

open access: yesSmall, EarlyView.
f‐Block element–based metal–organic framework (f‐MOF) thin films offer exceptional potential for luminescent, sensing, and energy‐related applications. This review surveys recent progress in their synthesis, characterization, and functional implementation, emphasizing the diversity of available thin‐film fabrication strategies. The convergence of these

Molecular dynamics study of 2-nitrophenyl octyl ether and nitrobenzene [PDF]

open access: yes, 2006
The pure organic liquids nitrobenzene (NB) and 2-nitrophenyl octyl ether (NPOE) have been studied by means of molecular dynamics simulations. Both solvents are extremely important in various interfacial processes, mainly connected with ion transfer ...

Functional polymer materials containing heavy group‐14 elements focusing on germanium and tin

open access: yesSmart Molecules, EarlyView.
The synthesis, functions, and applications of the polymers containing heavy group 14 elements focusing on germanium and tin are outlined. Owing to their large atomic radii and weak binding energies, the polymers show unique properties: chromism, luminescence, carrier mobility, and reactivity to produce radials and higher coordinated states.

Extraction of Alkali-Metal Picrates by Calixarene Esters in the Water–Nitrobenzene Solvent System. The Medium Effect on the Partition and Extraction Processes

open access: yesSupramolecular Chemistry, 2006
Based on distribution data involving alkali-metal (Na+, K+, Rb+ and Cs+) picrates in the presence and in the absence of calix[n]arene (n = 4, 6) esters, the extraction ability of these macrocycles in the water-nitrobenzene solvent system is established. Thus, partition and distribution constants in the mutually saturated solvents and ion-pair formation

Molecular basis of antibiotic sensing by the TetR family regulator CecR – a structural perspective

open access: yesThe FEBS Journal, EarlyView.
Escherichia coli CecR, a member of the TetR family regulators, senses selected antibiotics and activates the expression of a putative drug efflux pump. Although present in many pathogenic Enterobacteriales strains, CecR remains poorly characterized. We present the first CecR crystal structure, which reveals a unique tunnel‐like ligand‐binding cavity ...
