Image Capture is an application program from Apple that enables users to upload pictures from digital cameras or scanners which are either connected directly to the computer or the network. It prov...
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. The word was coined by the scientist Michael Faraday from the Greek words elektron and hodos, a way.
Asbestos (pronounced /æsˈbɛstəs/ or /æzˈbɛstəs/) is a set of six naturally occurring silicate minerals[1] which all have in common their eponymous asbestiform habit: long (roughly 1:20 aspect ratio...
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.
Light transmission and diffraction control element
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-c...
Membrane-electrode assembly
Heat conduction is the transfer of internal energy by microscopic diffusion and collisions of particles or quasi-particles within a body due to a temperature gradient.
A solar charger employs solar energy to supply electricity to devices or charge batteries. They are generally portable.
Field emission (FE) (also known as field electron emission and electron field emission) is emission of electrons induced by an electrostatic field. The most common context is field emission from a ...
In biology, the extracellular matrix (ECM) is a collection of extracellular molecules secreted by cells that provides structural and biochemical support to the surrounding cells. Because multicellu...
Cell culture is the complex process by which cells are grown under controlled conditions, generally outside of their natural environment. In practice, the term "cell culture" now refers to the cult...
Cytokines (Greek cyto-, cell; and -kinos, movement) are a broad and loose category of small proteins (~5–20 kDa) that are important in cell signaling - they are released by cells and affect the beh...
A diffusion barrier is a thin layer (usually micrometres thick) of metal usually placed between two other metals. It is done to act as a barrier to protect either one of the metals from corrupting ...
A neuron (/ˈnjʊərɒn/ nyewr-on or /ˈnʊərɒn/ newr-on; also known as a neurone or nerve cell) is an electrically excitable cell that processes and transmits information through electrical and chemical...
