Summary: This study investigated the effect of density on the survival rate, biomass production, profit, and morphological features of kelp. The results showed that survival rate was high and biomass production increased with increasing density. Profit also increased until a certain density threshold. The optimal density range for maximizing both profit and food quality was found to be 80-120 individuals per meter.

Summary: Stranded seaweed poses a serious threat to coastal areas when the tide recedes. This study investigated the potential use of Sargassum mitucum seaweed fiber in building construction. The results showed that a cob made with Sargassum muticum algae exhibited better thermal and hygroscopic properties compared to a cob made with flax fiber. The study also highlighted the global issue of sargassum algae expansion and suggested that utilizing stranded algae could improve the mechanical and hygrothermal performance of cob-based materials.

Summary: The aim of this study was to investigate the effects of environmental conditions, especially pH, and flour level on the rheological, structural, and antioxidant properties of model aqueous systems. The results showed that the level of flour mainly controlled the linear viscoelastic range of the suspensions, while the pH significantly affected the mechanical spectra. The power-law model satisfactorily fitted the flow behavior of the suspensions.

Summary: Seaweeds contain various bioactive compounds of interest to the food industry, such as phenolic compounds, polysaccharides, proteins, and vitamins. Green extraction technologies, such as pressurized hot water extraction, were used to obtain these compounds. The study found that the highest fucoidan content was recovered at 160°C, while the maximum phloroglucinol content and antioxidant activity were achieved at 220°C. Encapsulation of these bioactive fractions using mannitol was also investigated.

Summary: A series of protic N-heterocyclic carbene ligand precursors based on theophylline or adenine has been prepared and investigated for their reactivity and coordination chemistry towards iridium(III) centers. The formation of complexes appears to be highly influenced by the structure of the proligands. Notably, a particularly stable complex has been formed, allowing for fully reversible protonation/deprotonation of the coordinated NHC moiety. The acidity constant of the protonated complex was subsequently determined.

Summary: This study presents the in vitro and in vivo aroma release analysis of three espresso coffees using PTR-ToF-MS headspace and nosespace analysis. The study found that the roasting degree and varietal compounds were important factors in coffee discrimination. Despite the relatively low number of peaks detected in nosespace, coffee discrimination was still possible. There were significant qualitative and quantitative differences between headspace and nosespace profiles.

Summary: This study reports a series of sulfur-rich chelators capable of stably coordinating Hg-197m/g to a tumor-targeting vector. The ability of these ligands to effectively coordinate Hg2+ was demonstrated through theoretical calculations and experimental studies, including NMR and mass spectrometry. Radiolabeling and in vitro stability assays further confirmed the potential application of these ligands. The development of stable ligands for Hg-197m/g reported in this study lays the foundation for their personalized use in in vivo imaging and therapy.
