Wood chips contain numerous active compounds that can affect the wine's characteristics. They are commonly used in red grape wines, whisky, cherry and brandy, but in fruit wines, production is not typically utilised. The aim of this study was to compare the impact of an oak barrel ageing with the effect of the addition of chips made from various types of wood (oak, maple, cherry, apple) and with various degrees of toasting to the apple wines on their antioxidant, oenological and sensory properties. The oenological parameters, the polyphenols content, antioxidant activity and content of volatile odour-active compounds were assessed. It was shown that ageing in the presence of wood chips had a less noticeable effect on the oenological and sensory parameters of the wine than barrel ageing. Moreover, wood chips used did not significantly affect the acidity, alcohol and extract content of apple wines. Wines aged in the presence of oak chips (particularly lightly toasted) exhibited the greatest increase in polyphenols, while the polyphenol content of wines aged in the presence of other chips was not dependent on their toasting degree. The ageing of fruit wines with wood chips influences the volatile profile and the olfactory sensations, which can improve their quality.

In this study we monitored exposure to airborne dust in workers performing various tasks at two biomass-fuelled thermal power plants (27 and 46 MW) over six years. The plants are mainly fuelled by forest wood chips and, to a lesser extent, by agro-food products, with annual consumption of about 300 and 450 kt. We focused on inhalable wood dust because of its potential carcinogenicity to humans.

Several indexes have been proposed in the scientific literature and widely applied in many environments to evaluate the ecosystem multifunctionality. However, some indexes are based on the simple average of the environmental indicators (EIs) and ecosystem functions (EFs), which do not consider the ecosystem complexity and mutual relationships among the composing variables. In order to overcome these limitations, this study proposes a new method that modifies the ecosystem multifunctionality (EMF) index proposed by Maestre et al.

In this paper, we introduce a compact, single-sided stray field sensor for NMR relaxometry applications. The sensor consists of four main components: the magnet, the RF coil, the spectrometer, and the translation stage. Our proposed magnet, an improved design of the Profile NMR-MOUSE, is designed for low weight, compactness, and magnetic field homogeneity, achieved through various shim strategies using a mixed genetic algorithm.

This study investigates the development of electrically conductive panels for application as emergency detection sensors in smart house systems. These panels, composed of wood chips coated with polymeric methylene diphenyl isocyanate, were modified with carbon black and carbon fibers to enable detection of moisture, temperature, and pressure variations. Manufactured via hot pressing, the panels retained standard mechanical properties and exhibited stable performance under diverse environmental conditions.
