Although experimental studies have demonstrated the antipredatory advantages of camouflage and its associated costs, few studies have examined the evolution of camouflage in a phylogenetic context. We use phylogenetic comparative methods to examine evolutionary trade-offs associated with camouflage in the crab superfamily Majoidea. The majoids, or spider crabs, are known for their decoration be...

Tunable control over the functionalization of graphene is significantly important to manipulate its structure and optoelectronic properties. Yet the chemical inertness of this noble carbon material poses a particular challenge for its decoration without forcing reaction conditions. Here, a mild, operationally simple and controllable protocol is developed to synthesize hydroxylated graphene (HOG...

An electroless deposition method comprised of seed formation and subsequent seeded growth is developed for the decoration of surface-grown single-walled carbon nanotubes (SWCNTs) with gold nanoparticles of controlled size and interparticle distance. The density of the gold nanoparticles is determined by the density of seeds. Gold seeds are used for the SWCNT arrays grown on SiO(x)/Si substrates...

A special feature of Orthodox religious buildings is the presence in worship hall works architecture, artistic murals, icons, frescoes, iconostases historical and cultural value. The specificity buildings: churches, temples cathedrals also year-round services gatherings a large number parishioners staff, reaching several thousand people. It known that dozen candlesticks with burning candles are...

Abstract Nb-containing catalysts have the potential to catalyze carbon dioxide (CO 2 ) reduction due their strong surface acidity and CO activation sites. Still, they not been widely used in development design of theoretical/cost/safety limitations. Related advances continuously reported literature, demonstrating some extent promise catalytic applications this area. In minireview, we discuss st...

Avian nests are frequently concealed or camouflaged, but a number of species builds noticeable nests or use conspicuous materials for nest decoration. In most cases, nest decoration has a role in mate choice or provides thermoregulatory or antiparasitic benefits. In territorial species however, decorations may serve additional or complementary functions, such as extended phenotypic signaling of...
