Finals Flashcards
It is the knowledge communicated or obtained concerning a specific fact or circumstance
Information
Facts provided or learned about something or someone.
Information
A period starting in the last quarter of the 20th century.
Information Age
Information became effortlessly accessible through publications and through the management of information by computers and computer networks.
Information Age
Tor F
The information age is a true new age, based upon the interconnection of computers via telecommunications, with these information systems operating on both real-time and as-needed basis. Furthermore, the primary factors driving this new age forward are convenience and user-friendliness which, in turn, will create user-dependence. (James R. Messenger, Theory of Information Age, 1982)
True
Human cost of information overload.
Information Anxiety
It is produced by that ever-widening gap between what we understand and what we think we should understand. It is the black hole between data and knowledge, and what happens when information doesn’t tell us what we want to know? (Richard Saul Wurman, Information Anxiety)
Information Anxiety
Information must compete.
Newer is equated with truer.
Selection is a viewpoint.
The media sells what the culture buys.
Truths of the Information Age (pt1)
The early word gets the perm.
You are what you eat and so is your brain.
Anything in great demand will be counterfeited.
Truths of the Information Age (pt2)
Undead information walks ever on.
Media presence creates the story.
The medium selected the message.
The whole truth is a pursuit.
Truths of the Information Age (pt3)
A technological advancement or breakthrough that is making use of matters or different materials at small scale.
Nanotechnology
The idea of manipulating and controlling things on an extremely small scale.
Nanotechnology
tudy of phenomena and fine-tuning of materials at atomic, molecular, and macromolecular scales; properties differ from those at a larger scale (according to European commission)
Nanotechnology
Technology working with and producing things at atomic level
How much smaller is this?
Nanotechnology
approx. 1 and 100 nanometers
They use atoms and molecules to design new materials that have improved or new properties
Nanotechnologist
T or F
Nanomaterials have leaser surface area, resulting to increased chemical reactivity
Decreasing size of particles is related to changes in particle’s magnetic, optical, and electrical properties
False
Nanomaterials have greater surface area, resulting to increased chemical reactivity
Decreasing size of particles is related to changes in particle’s magnetic, optical, and electrical properties
Possess special size-dependent properties such as: color, fluorescence, melting point, and chemical reactivity which can be used for plenty of purposes.
Note

SMC
Made up of a clear silicone microfluidic chamber
Provide faster, cheaper, and far more accurate results than any other available diagnostic equipment
Benefits of nanotech in med
LOAC
Has developed and can have promising contributions in diagnostics, drug delivery, molecular imaging, and tissue welding among others LAB-ON-A-CHIP
Benefits of nanotech in med
Single-Walled carbon nanotubes
Dr. Robert Haddon used this as a material scaffolding to hold up regenerating bone
Single-Walled carbon nanotubes
Benefits of Nanotechnology in the environment
Ferroxane membrane - generated from iron oxide nanoparticles by Center for Biological and Environmental Nanotechnology (CBEN)
Can be used as waste treatment & water purification
Silver nanoclusters -
catalysts that can significantly reduce the polluting by-products generated in the production of paints, household detergents and automotive brake fluids
Benefits of Nanotechnology
in the food industry
Nanocomposites - heterogeneous materials comprising multiple different phase domains
Nano clay schematics
Packaging materials
Exhibit good gas–barrier properties against visible and UV light
Benefits of Nanotechnology
In electronics
LED and OLED
Organic light-emitting diodes
Brighet, thinner, lighter, flexible, easier to produce, can be made to larger sizes and consume much less power
Magnetic random access memory - Able to boot almost instantly, can quickly and effectively save data during a system shutdown
Silver nanoparticle ink - forming conductive lines and print prototype circuit board
Benefits of Nanotechnology
in Electricity
Energy is not widely available to many people around the world.
Richard E. Smalley
Nobel laureate
Have said that energy tops the list of the top 10 problems facing humanity over the next 50 years
