MoS2@ZnO nanoheterostructures were synthesized by electrospark erosion of zinc granules in a hydrogen peroxide solution and simultaneous addition of MoS2 nanostructured powder into the reaction zone. The morphology, size of the crystallites, as well as elemental and phase composition of the prepared structures, were examined using transmission electron microscopy and X-ray diffraction analysis. It was found that the synthesized products represent heterostructures containing MoS2 nanoparticles formed on ZnO nanoparticles. Raman spectroscopy and photoluminescence analysis were also used for characterization of the prepared heterostructures. The obtained MoS2@ZnO nanostructures revealed an intense broad emission band ranging from 425 to 625 nm for samples with different fractions of MoS2. Photocatalytic measurements showed that the maximal hydrogen evolution rate of the prepared nanoheterostructures was about 906.6 μmol·g-1·h-1. The potential of their application in photocatalytic water splitting was also estimated.The purpose of this study is to understand the current status of food insecurity in Korea and the US and to compare the relationship of food insecurity with nutrient intake and depression. Data from the 2014 Korea and the 2013-2014 US National Health and Nutrition Examination Surveys were analyzed, and a total of 3102 Korean and 3234 American adults aged 20-64 years were included. Study subjects were classified into three groups according to degree of food insecurity assessed by the 18-item Household Food Security Survey Module food secure (FS), mildly food insecure (FI 1), and moderately-to-severely food insecure (FI 2) groups. Energy and nutrient intake were assessed using a 24-h dietary recall. Depression was measured using the Patient Health Questionnaire-9 (PHQ-9) screener. The prevalence of food insecurity was 17.2% in Korea and 26.4% in the US. In both countries, the people in the FI 2 group had lower incomes and education levels and were mostly single. Energy and nutrient intake differed by food insecurity status. In both Korea and the US, adults with moderate-to-severe food insecurity (FI 2) consumed fewer proteins, fiber, potassium, and vitamin C. Additionally, the FI 2 groups had higher proportions of people not meeting the Dietary Reference Intake for protein, potassium, niacin, and vitamin C than the FS groups in Korea and the US. FI 2 people were three times more likely to be depressed than FS group; this difference was stronger in Korea than the US. We found that the prevalence of food insecurity was higher in the US than in Korea, and food insecurity was associated with reduced nutrient intake and increased odds of depression in both Korean and US adults. Therefore, food insecurity is an important public health issue at both the individual and national levels. Continuous monitoring and new intervention activities to promote food security are needed.Technical lignins produced as a by-product in biorefinery processes represent a potential source of renewable carbon. In consideration of the possibilities of the industrial transformation of this substrate into various valuable bio-based molecules, the biological deconstruction of a technical soda lignin by filamentous fungi was investigated. The ability of three basidiomycetes (Polyporus brumalis, Pycnoporus sanguineus and Leiotrametes menziesii) to modify this material, the resultant structural and chemical changes, and the secreted proteins during growth on this substrate were investigated. The three fungi could grow on the technical lignin alone, and the growth rate increased when the media were supplemented with glucose or maltose. Repotrectinib The proteomic analysis of the culture supernatants after three days of growth revealed the secretion of numerous Carbohydrate-Active Enzymes (CAZymes). The secretomic profiles varied widely between the strains and the presence of technical lignin alone triggered the early secretion of many lignin-acting oxid
