Nanofibers were first produced via electrospinning more than four centuries ago. [28] [29] Beginning with the development of the electrospinning method, English physicist William Gilbert (1544-1603) first documented the electrostatic attraction between liquids by preparing an experiment in which he observed a spherical water drop on a dry surface warp into a cone shape when it was held below ...
Electrospinning is a fiber production method that uses electrical force (based on electrohydrodynamic [1] principles) to draw charged threads of polymer solutions for producing nanofibers with diameters ranging from nanometers to micrometers.
Nanofabrics research is an interdisciplinary effort involving bioengineering, [5] molecular chemistry, physics, electrical engineering, computer science, and systems engineering. [3] Applications of nanofabrics have the potential to revolutionize textile manufacturing [ 6 ] and areas of medicine such as drug delivery and tissue engineering .
A nanoparticle or ultrafine particle is a particle of matter 1 to 100 nanometres (nm) in diameter. [1] [2] The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 100 nm in only two directions.
THERE ARE A lot of complex scientific topics present in Netflix's 3 Body Problem (presented, believe it or not, in a far more digestible way than the intense concepts presented in author Cixin Liu ...
Polyaniline nanofibers are a high aspect form of polyaniline, a polymer consisting of aniline monomers, which appears as discrete long threads with an average diameter between 30 nm and 100 nm. Polyaniline is one of the oldest known conducting polymers , being known for over 150 years. [ 2 ]
Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
