Medieval times were neither dark nor grey; natural light illuminated colourful scenes depicted in paintings through coloured windows and via artificial beeswax candlelight. When we enter, for example, a church to inspect its historic treasures ranging from mosaics to depictions of saints, we do this under quite unfavourable conditions; particularly as we mainly depend on artificial halogen, LED...

BACKGROUND In the natural environment, photodegradation is one of the most common degradative processes of pesticides. In order to reduce the photodegradation of pesticides, and so increase their killing activity against target pests, chitosan-coated beeswax solid lipid nanoparticles (CH-BSLNs) were prepared by a combination of hot homogenization and sonication, with deltamethrin as an active i...

A bilayer anodic film/beeswax–colophony is proposed for improving the corrosion resistance of magnesium alloy surface. The was synthesized on AZ31 by anodization and subsequent dip coating, behavior investigated electrochemical measurements weight loss test in Ringer lactate at 37 °C. improved four orders magnitude, as demonstrated ~104 times lower current density polarization curves higher fil...

A multi-analytical approach is proposed for the detection and quantitative characterization of waxes in wall paintings from Vesuvian area, particular House Skeleton, Deer two Atriums Herculaneum (Italy). Different types waxes, animal, vegetable, mineral artificial origin, were investigated, as reference materials, by Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy gas chromat...

Beeswax is a multicomponent material used by bees in the genus Apis to house larvae and store honey and pollen. We characterized the mechanical properties of waxes from four honeybee species: Apis mellifera L., Apis andreniformis L., Apis dorsata L. and two subspecies of Apis cerana L. In order to isolate the material effects from the architectural properties of nest comb, we formed raw wax in ...
