The tribological properties of PTFE and PDA+PTFE coatings in oil-lubricated conditions were studied. Both coatings showed hydrophobic behavior. The coatings
Polydopamine (PDA) is a biopolymer inspired by mussel chemistry [1]. It has attracted much attention owing to its interesting properties and ease of synthesis.

Polydopamine (PDA) is a biopolymer inspired by mussel chemistry [1] It has attracted much attention owing to its interesting properties and ease of synthesis An auto-oxidation process under mild conditions in dopamine solution [2] can yield nanoscale PDA powder with controllable size [3] smooth crack-free and thin coatings
Pushdown automata (PDA) recognize context free languages These automata are like non-deterministic finite state automata but have an extra component called a stack It is this extra component that allows the automaton to have memory (in principle infinite amount of memory) and to recognize some nonregular languages
pathogen detection Polydiacetylene (PDA) is an ideal choice for use as a sensor due to its unique optical properties PDA molecules can form thin films or vesicles that change color from deep blue to red in response to different stimuli like temperature pH and the presence of biological molecules PDA films and vesicles have been
The Package Deal Account of Laws and Properties (PDA)** I Introduction One of the primary goals of the sciences is the discovery of the laws that explain natural phenomena There is a tradition in physics that originated in the 17th century especially with the success of Newtonian mechanics according to which physics aims to discover the world [s
Also PDA’s being “algorithmic” are often easier to use when arguing that a language is a CFL Example: It is easy to see how a PDA can recognize balanced parentheses; not so easy as a grammar But all depends on knowing that CFG’s and PDA’s both define the CFL’s
