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

Mass 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).

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

Nordic Journal of Botany, EarlyView.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.

A review on biodiesel micromixers: Types of micromixers, configurations, and flow patterns

Heliyon
The production of biodiesel conventionally relies on batch reactors for the transesterification of oil and alcohol. However, the inherent limitations of batch-wise biodiesel production, including biphasic oil and alcohol, the establishment of equilibrium

Synthetic polymer nanocarrier enhances dsRNA stability but not RNAi efficacy in Brassicogethes aeneus

Pest Management Science, EarlyView.
Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Biodiesel production

, 2018
Bu çalışmada, ayçiçek yağı ve metanol kullanılarak çözücüsüz ortamda Lipozyme TL IM katalizli biyodizel üretme olasılığı araştırılmıştır. Aynı zamanda farklı reaksiyon koşullarının ayçiçek yağının enzimatik metanolizine etkileri de çalışılmıştır. Yağ miktarına göre kütlece %4.5, %9, %,13, %18 ve %27 enzim ile sırasıyla 2:1, 4:1, 6:1, 8:1, ve 10:1 molar
