Abstract:
... We studied the endolichenic fungal communities from saxicolous lichens occupying the cobbles at Nahal Boker, the central Negev Desert, Israel. Overall, 101 species belonging to 64 genera were isolated from 12 lichen species collected in three seasons from the south-facing slope (SFS) and north-facing slope (NFS) of the wadi. The endolichenic communities possessed a set of traits, which helped them ...

Abstract:
... The rapid innovation of flexible smart electronics has increased the demand for flexible thermally conductive films with the high performance of electromagnetic interference shielding (EMI). This study focuses on graphene nanoplatelets/polyurethane (GnP/PU) films that were fabricated utilizing the solution casting approach. The stretching-induced alignment method was then used to align the GnP she ...
... Although nanocomposite films had shown excellent potential in antibacterial food packaging, their potential harmful impact limits their further application in reality. Therefore, exploring a Generally Recognized As Safe (GRAS) nanomaterial that has antibacterial ability is the pioneer for the fabrication of a real edible nanocomposite-based antibacterial packaging film. Herein, for the first time ...

Abstract:
... Salmonella contamination of chocolate-derived products has caused several outbreaks and recalls in recent years. Earlier research found that reducing moisture content or water activity of low-moisture foods sharply enhances the resistance of Salmonella during thermal treatments. However, there is a lack of data that correlates the relationship between temperature, water activity (aw), and thermal ...

Abstract:
... The sulfur-containing odor emitted from sludge composting could be controlled by sulfide oxidizing bacteria, yet mesophilic strains show inactivation during the thermophilic stage of composting. Aimed to investigate and characterize the thermotolerant bacterium that could oxidize sulfide into sulfate, a heterotrophic strain was isolated from sewage sludge composting and identified as Paenibacillus ...

Abstract:
... Viticultural production and wine quality are profoundly affected by climate. Characterising winegrape-growing regions based on climatic variables provides scientific guidance for the wine industry in vineyard site and winegrape cultivar selection. This research used a modified multicriteria climatic classification system based on three representative indices, Huglin index, cool night index and gro ...

Abstract:
... As a conserved protein degradation system, autophagy plays important roles in removing or degrading misfolded and denatured proteins to maintain the homeostasis in cells. As a core member of autophagy, the involvement of ATG8 in plant tolerance to abiotic stress is paid more attention. In this study, by the SMART online tool, the Atg8 conserved domain was detected in CaATG8e, and by the MEGA11 sof ...

Abstract:
... Cultured Greenshell™ mussels (Perna canaliculus) are exposed to biotic and abiotic stresses, all of which can negatively impact growth, fecundity, and survival. These impacts are especially pronounced in sensitive larval and spat stages and may result in substantial losses when spat are transferred from hatchery to grow-out farms. Immersion in solutions of plant extracts have been shown to improve ...
... The aim of this study was to evaluate the physiological and biochemical heat responses of grafted tomato (Solanum lycopersicum L.) seedlings and their changes during the post-stress recovery period. Heat-tolerant ‘Celebrity’ and heat-sensitive ‘Arkansas Traveler’ tomatoes were grafted onto a commercial ‘Maxifort’ rootstock, and transplants were grown in growth chambers for 14 days of heat treatmen ...

Abstract:
... It remains a great challenge to manufacture polylactic (PLA) with high strength, ductility, and heat resistance simultaneously. Herein, PLA/poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanoribboned composites, the highly oriented PHBV nanoribbons decorated by the PLA lamella, are successfully achieved through the multistage stretching extrusion (MSE) system. SEM confirms that in-situ highly ...

Abstract:
... Poly(lactic acid) (PLA) has attracted much attention as a substitute for petroleum-based plastics, but its low heat resistance limits its application range in packaging fields and disposable products. This paper summarizes the structural factors affecting the heat resistance of PLA and systematically summarizes methods to improve its heat resistance. PLA is a semi-crystalline polymer, and crystall ...

Abstract:
... Silicone rubber (SR)-based thermal conductive composites is a good candidate for heat-resisted thermal interface materials (TIM). It’s a challenge to increase thermal conductivity (TC) and get thick sample as the difficulty of vulcanizing SR in core layer. Herein, a highly thermal conductive and 10 mm SR/graphite (Gr) with oriented Gr (O-SR/Gr) was prepared by pre-vulcanization and multilayer-stac ...

Abstract:
... The synthesis of Janus nanosheets using κ-carrageenan (κ-Ca) as a green template endows a greener and more straightforward method compared to traditional approaches of using wax template. We hypothesize that the hydrogen bonding interaction between κ-Ca and graphene oxide (GO) allows partial masking of GO’s single facet, paving the way for the asymmetric modification of the exposed surface. GO is ...

Abstract:
... The thermal resistance of a borehole heat exchanger (BHE) varies considerably depending on the position of the pipe legs. However, the pipe position cannot be fully controlled during construction because of the extreme slenderness of the BHEs. Therefore, the borehole's thermal resistance (Rb) estimated from one BHE is not representative of the entire borefield. This study probabilistically quantif ...

Abstract:
... The identification of biological pattern is often complicated by the lack of methodologically consistent data with broad geographic coverage, especially when considering functional characteristics of organisms that differ greatly in body size and morphology. In our study (Dahlke et al. 2020), we addressed the problem of data scarcity by using different types of observational and experimental data ...

For instance, flat heat pipes have recently been proposed as thermal absorber for photovoltaic/thermal (PV/T) applications or for the thermal management of batteries. Following promising surface cooling results, increasing the fundamental knowledge of the ...

Abstract:
... Structural adhesive play an important role in the manufacturing of composite structures. Here, a high-temperature resistant bismaleimide (BMI) structural film adhesive was prepared by using a chemically modified BMI resin as the matrix with poly(phthalazinone ether nitrile ketone) (PPENK) as the film-forming agent. The toughness of the adhesive was greatly enhanced by adding vinyl-terminated butad ...

Abstract:
... Accurate measurements and physical understanding of thermal boundary resistance (R) of two-dimensional (2D) materials are imperative for effective thermal management of 2D electronics and photonics. In previous studies, heat dissipation from 2D material devices was presumed to be dominated by phonon transport across the interfaces. In this study, we find that, in addition to phonon transport, ther ...

Abstract:
... MAIN CONCLUSION: Genome size of alpine plants is not related to their resistance against frost and heat. Genome size is a variable trait in angiosperms, and it was suggested that large genome size represents a constraint in stressful environments. We measured genome size and resistance to frost and heat in 89 species of plants from tropical and temperate alpine habitats. Genome size of the species ...
