Abstract Recombinant spider silk proteins (spidroins) have multiple potential applications in development of novel biomaterials, but their multimodal and aggregation-prone nature complicated production straightforward applications. Here, we report that recombinant miniature spidroins, importantly also the N-terminal domain (NT) on its own, rapidly form self-supporting transparent hydrogels at 37 °C. The gelation is caused by NT α-helix to β-sheet conversion formation amyloid-like fibrils,...

Gastropods, such as snails and slugs, can excrete mucus to aid in movement adhesion. However, very few studies have examined the physical relationship between composition function. Here, we explore role of polymers (specifically their proteins) influence on material properties locomotive mucus. Using a range spectroscopic, thermal, rheological analytical tools, characterised from six gastropod species across four families. We report that all tested consisted 97%–99% water, remaining 1%–3%...

ABSTRACT Venom spitting is a defence mechanism based on airborne venom delivery used by number of different African and Asian elapid snake species (‘spitting cobras’; Naja spp. Hemachatus spp.). Adaptations underpinning have been studied extensively at both behavioural morphological level in cobras, but the role physical properties itself its effective projection remains largely unstudied. We hereby provide first comparative study non-spitting cobras. measured viscosity, protein...

An equation model for calculating the adiabatic temperature of wet-bulb thermometer has been obtained empirical fit through a meteorological database, specificly trough relative humidity and air temperature. A comparison results calculations with use this from database was made. The deducted is valid dry bulb range 3°C to 35°C percentage in 7% 97%. Normalized errors are less than 5.5%. It means maximum variation 0.55°C data. However, error represents only 3.6% data sample. satisfactory.
