In this paper we assess the price reaction, performance and volatility timing of European investment funds during the outbreak of Covid-19. We analyze the time period between January and June 2020 and demonstrate that while most of the investment funds exhibit stressed performance, social entrepreneurship funds endured resilience. This performance remained robust during the various stages of evolution of this contagion. The social funds also demonstrated volatility timing that was absent for most of their counterparts. We attribute the overall stability of these funds to their niche investments in social enterprises that specialize in providing innovative solutions for social issues.

Within coating formulations, microcapsules serve as vehicles for delivering compounds like catalysts and self-healing agents. Designing microcapsules with precise mechanical characteristics is crucial to ensure their contents' timely release and minimize residual shell fragments, thereby avoiding adverse impacts on the coating quality. With these constraints in mind, we explored the use of 1 cSt PDMS oil as a diluent (porogen) in trimethylolpropane trimethacrylate (TMPTMA)-based to fabricate microcapsules with customized mechanical properties and submicrometer debris size after shell breakup that can encapsulate a wide range of compounds.

The biomass of native microorganisms in food waste (FW) suitable for accelerated composting is initially low and requires time for adaptation. Adding of efficient hydrolytic microorganisms should be able to enhance compost-specific microbial activity, adjust microbial community structure, and potentially hasten FW biodegradation. This study aimed to identify bacterial and fungal strains with growth characteristics suitable for accelerating FW composting.

Accurately assessing potential side effects following botulinum neurotoxin (BoNT) injection remains a formidable challenge. To address this issue, an innovative approach is developed that combines a wearable temperature sensor with a sophisticated volatilomics technique, aimed at facilitating the rapid and convenient prediction of potential physical discomfort related to latrogenic botulism. The investigation identifies five volatile organic compounds (VOCs)-acetone, styrene, ethanol, 2-pentanone, and n-butano-as promising markers indicative of BoNT poisoning.

To investigate the microbial diversities and dynamic quality properties of kombucha, the successional changes with different periods from four regions were comprehensively characterized and compared. A total of 197 indigenous yeast and bacterial strains were isolated, involving Gluconobacter, Komagataeibacter, Starmerella and Zygosaccharomyces spp. The successional dynamics of the kombucha communities in different regions were evaluated.

Objective: Early recognition of sepsis is essential for timely initiation of adequate care. However, this is challenging as signs and symptoms may be absent or nonspecific. The cascade of events leading to organ failure in sepsis is characterized by immune-metabolic alterations.
