Thermally activated delayed fluorescence exciplex sensitizers with fast reverse intersystem crossing for improving efficiency stability of organic light‐emitting diodes based on multi‐resonance emitters

open access: yesFlexMat, EarlyView.
Two exciplex emitters are constructed based on a host‐guest doping strategy, and their exciton dynamics processes are investigated in depth. High‐performance OLEDs are fabricated by employing these exciplexes as emitters or sensitizers, providing excellent electroluminescence efficiencies and low efficiency roll‐offs.

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

open access: yesFood Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic

On the synthesis of furans and furan fatty acids [PDF]

open access: yes
This thesis describes the use of silver nitrate and iodine to promote 5-endo-dig cyclisations in the synthesis of furans. The oxidation of furylethanols will be discussed as will methods to synthesise furylacetic acids. The total synthesis of a natural product, Plakorsin B will be described along with the total synthesis of the furan fatty acids F5 and

Integrated pretreatment and fermentation strategies for L‐lactic acid production from brewers' spent grain using native Streptococcus infantarius and Bacillus coagulans

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Brewers' spent grain (BSG) is an abundant lignocellulosic byproduct of the brewing industry with strong potential as a renewable substrate for biotechnological production of lactic acid (LA). This study evaluated integrated pretreatment, enzymatic hydrolysis, and fermentation strategies to enable efficient production of optically ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Single‐Cell Transcriptomics and Deep Learning Link N‐(2‐Furoyl) Glycine to GLRX3 in Gastric Cancer

open access: yesMed Research, EarlyView.
ABSTRACT Gastric cancer remains a health burden, and its metabolic drivers are poorly defined. N‐(2‐furoyl) glycine, a circulating metabolite, has been implicated in tumor biology. We investigated its causal role in gastric cancer and the underlying mechanism.
