Summary: Consumers' demand for nutritious and healthy foods has driven the development of prebiotic foods. In the coffee industry, the waste/by-products generated from the transformation of cherries into roasted beans can be used as sources of prebiotic ingredients. Coffee by-products contain dietary fiber and other components that can improve gut health and stimulate beneficial bacteria, making them potential prebiotic ingredients. However, further in vivo studies are needed to validate these findings obtained in vitro. This review highlights the potential of coffee by-products in the development of functional foods, contributing to sustainability, circular economy, food security, and health.

Summary: Despite a strong track record, microbial drug discovery faces challenges with high rates of rediscovery and the lack of systematic characterization of less explored strains. A metabolomic study of Planomonospora isolates revealed a correlation between chemical diversity and strain phylogeny, identifying previously reported metabolites and gene clusters connected to biosynthetic capabilities. This study highlights the value of metabolomic studies in exploring poorly understood taxa and provides insights into the biosynthetic potential of the genus Planomonospora.

Summary: This article argues for the importance of pro-environmental habits in sustainability research and highlights the potential of habit theory in driving pro-environmental behaviors. It emphasizes the impact of habits on automatic processes of behavior, how the environmental context shapes habits, and how habits influence our values and self-identity. Studying sustainable behaviors through a habit lens can lead to a more comprehensive understanding and complement current approaches that focus on reasoned decisions and intrinsic motivations.

Summary: Ovarian cancer is a deadly gynecological cancer where the immune system, particularly the complement system, plays a crucial role. Current therapeutic strategies can only temporarily control the disease, with many patients developing resistance to treatment. Immunotherapy has shown limited success in ovarian cancer, highlighting the need for further research into immune components for more effective treatment options.

Summary: Mycobacterium tuberculosis manipulates the host immune response and expresses specific genes during infection. Current immunodiagnostics lack the ability to detect progression from latent infection to active disease, highlighting the need for new tuberculosis biomarkers that can accurately diagnose TB infection and monitor treatment efficacy. Iron regulation by the host plays a crucial role in the susceptibility and outcome of Mtb infection, with certain genes being induced during iron limitation and intracellular growth of Mtb.

Summary: The study found that approximately 25% of patients had moderate hostility and 11% had high levels of hostility, with about 20% being BSI-HOS cases. Hostility was higher in patients with a formal ICD-10 psychiatric diagnosis (mainly major depression, other depressive disorders, anxiety disorders). Hostility was associated with hopelessness, anxious preoccupation, poorer quality of life, worries (mainly interpersonal relationship problems), and inability to openly discuss these problems within the family.

Summary: This study investigated six microalgal strains capable of growing at low pH conditions and compared their biomass productivity with other commercially relevant microalgae. The results showed that five strains had autotrophic biomass productivities comparable to other microalgae, indicating their potential for large-scale autotrophic biomass production under acidic conditions. Additionally, two strains demonstrated the ability to grow mixotrophically and heterotrophically.

Summary: As nations transition towards low or net zero carbon economies due to global climate change, the need for practical alternative fuels is urgent. Hydrogen gas is considered one of the most desirable substitutes for traditional hydrocarbons, but obtaining "green" hydrogen from low or zero carbon footprint sources presents challenges. Research focuses on practical techniques for producing "green" hydrogen through photocatalytic or photoelectrocatalytic processes. However, the capability of this technology to produce hydrogen at scale has faced significant issues. This road map article explores various aspects of photocatalytic and photoelectrocatalytic hydrogen generation, including processes, materials science, reactor engineering, and biomass reforming applications.

Summary: Effective removal of dilute nitrogen oxide (NO, ppb) without NO2 emission is still challenging in environmental pollution control. The construction of photocatalysts with diversified microstructures and atomic arrangements has been found to promote NO adsorption, activation, and complete removal without secondary pollution. In this study, the microstructure of ZnO photocatalysts was regulated by altering the reaction temperature and alkalinity, resulting in enhanced NO removal and reduced NO2 yields through defect-related surface-interface aspects. Mechanistic exploitations revealed that regulated microstructures, defect-related charge carrier separation, and strengthened surface interactions contributed to improved NO removal and simultaneous avoidance of NO2 formation. This investigation sheds light on the facile regulation of microstructures and the roles of surface chemistry in the oxidation of low concentration NO in the ppb level upon light illumination.

Summary: This article explores TiO2 nanomaterials as promising photocatalysts for NOx depollution from air under sunlight irradiation. Experimental results show that brookite TiO2 exhibits comparable photocatalytic activity to benchmark TiO2 P25 and higher selectivity towards the conversion of NOx into nitrate ions. The enhanced selectivity is attributed to the higher density of defects on brookite TiO2 surfaces, which facilitates the adsorption of NO2 while favoring the dissociative adsorption of water.

Summary: Destabilizing ligand-stabilized semiconductor nanocrystal solutions results in the formation of macroporous self-supporting nanocrystal networks called hydrogels, which have high surface accessibility. The delocalization of charge carriers in these gels extends their mobility and enhances photocatalytic reactions. Recent advances in colloid chemistry enable the synthesis of nanocrystals with specific physicochemical properties, which, when combined with nanocrystal-based hydrogels, can lead to novel materials with optimized photocatalytic properties. This study demonstrates that CdSe quantum dots, CdS nanorods, and CdSe/CdS dot-in-rod-shaped nanorods as nanocrystal-based hydrogels show significantly higher hydrogen production rates compared to their ligand-stabilized nanocrystal solutions. The gel synthesis through controlled destabilization by ligand oxidation ensures high surface-to-volume ratio, facilitates photocatalytic hydrogen production without a co-catalyst, and overcomes colloidal instability issues in photocatalysis. X-ray photoelectron spectroscopy and photoelectrochemical measurements confirm the advantageous properties of these 3D networks for photocatalytic hydrogen production.

Summary: This study investigated the mechanistic details of glucose photoreforming over TiO2 and Pt/m-TiO2 catalysts. The alpha-scission mechanism of glucose oxidation was confirmed by the formation of arabinose and formic acid in the initial oxidation step. The selectivity to sugar products and formic acid differed over Pt/TiO2 and TiO2, with Pt/TiO2 showing lower selectivity to formic acid due to enhanced adsorption/conversion. In situ ATR-IR spectroscopy revealed the presence of molecular formic acid and formate on the surface of both catalysts, suggesting the dominance of formic acid oxidation in glucose photoreforming.

Summary: This study introduces a novel voltammetric method for determining emamectin benzoate (EB) using a cathodically pretreated boron-doped diamond electrode (CTP-BDDE) for the first time. The CPT-BDDE electrode showed a well-defined irreversible signal at -1.35 V (vs. Ag/AgCl) using cyclic voltammetry. Square wave voltammetry was used to quantify EB concentrations in real sea water samples, and the method was found to be unaffected by other insecticides and inorganic ions present in seawater.
