Metal–Organic Frameworks (MOFs) have attracted increasing attention for the creation of solid-state platforms for catalysis applications. In this review article, we present strategies to employ MOF-based materials in photochemical hydrogen production. The scope ranges from the incorporation of single functions (catalyst or photosensitizer) to multifunctional MOFs that combine both light-harvest...

The present study was carried out to establish knowledge of consequence for setting up guidelines of importance for production of competitive organic pork of high quality. Performance and meat quality characteristics were compared between three organic pig production systems based on indoor housing with access to an outdoor area and a Danish conventional indoor system including 100% concentrate...

Laboratory data and corrected estimates of cosmic ray dose are used to predict the thickness and survivability of the cosmic rayproduced, primordial comet mantle ("crust"). These results support the hypothesis that the refractory mantle produced by cosmic ray irradiation of a new comet may be able to survive a comet's entry into the inner solar system for many revolutions. Because this mantle m...

Objectives • Investigate different strategies for selective growth of hydrogen-producing bacteria (e.g., heat selection and pH control, hydraulic loading) in a mixed culture environment. • Determine the biokinetics parameters of hydrogen-producing microorganisms. • Identify and quantify hydrogen-producing bacterial population in a complex microbial community background using nucleic acid based ...

Organic pig production differs in many ways from conventional production of pigs, e.g., in antibiotic use, herd structure, feeding regimes, access to outdoor areas and space allowance per pig. This study investigated if these differences result in a lower occurrence of antibiotic resistance in organic slaughter pigs in Denmark, France, Italy and Sweden. Samples were taken from the colon content...

Although microalgae produce value-added products, such as lipids, pigments, and polysaccharides using light carbon dioxide, these intracellular products require costly downstream processes extraction purification. Thus, extracellular are desirable for economic production. While reported before, the secretion of glycolic acid by microalgal photorespiration has not received attention industrial a...

Phaseout of the fumigant methyl bromide, restrictions on organophosphates, environmental problems with neonicotinoids and pyrethroids, pest resistance, and the exponential growth of organic agriculture has created a market for alternatives (Weston et al. 2004; Moran 2010; Quarles 2011ab; 1993a). Beneficial nematodes, Bacillus thuringiensis (BT), and a large array of fungi, viruses, and bacteria...
