The IUCN Red List is a critical indicator of the health of the world's biodiversity. Far more than a list of species and their status, it is a powerful tool to inform and catalyze action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive. It provides information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions that will help inform necessary conservation decisions.

Forward curved blade fans. Forward curved blades... are mounted on what is often referred to as a squirrel cage rotor. Fans with these blades produce a high volume for their size, and are lightweight and economical. Because forward curved blades can collect deposits they are only used for handling clean air. Forward curved blade fans are used extensively in small air handling equipment(less than 610 mm diameter). Their efficiency is lower than that of airfoil fans. The scroll is often similar to other centrifugal fan designs, however, the clearance between the impeller and inlet is not as critical as for airfoil or backward inclined blade impellers.

The Binary Colloidal Alloy Test-3 is an Exploration Systems’ transition flight experiment in the Human System Research and Technology area. BCAT-3 provides a unique opportunity to explore fundamental physics and simultaneously develop important future technology, including computers operating on light, complex biomolecular pharmaceuticals, clean sources of geothermal power, and novel rocket engines for interplanetary travel. These studies depend entirely on the microgravity environment provided by the International Space Station(ISS) ;in all other locations accessible to science, gravity dominates and precludes investigation of any other effects of interest. The experiment itself [consists of] photographing samples of colloidal particles with a digital camera onboard the ISS. Colloids are tiny nanoscale spheres of plexiglass a thousand times smaller than the width of a human hair(submicron radius) that are suspended in a fluid. They are ubiquitous(e. g., milk, smoke, and paint) and therefore interesting to study directly. Colloids are also small enough that they behave much like atoms and so can be used to model all sorts of phenomena because their size, shape, and interactions can be controlled. The 10 samples in BCAT-3 are made from the same ingredients, each a recipe with different proportions, and are grouped into three experiments :critical point, binary alloy, and surface crystallization. [Text followed by an illustration of a BCAT-3 sample holder. ]

CONT

BCAT-3 is comprised of three separate experiments, which are individually referred to as a binary alloy(BCAT-3-BA), surface crystallization(BCAT-3-SC) and critical point(BCAT-3-CP). The critical point investigation is continuing with additional samples on future ISS [International Space Station] expeditions and will be referred to as Binary Colloidal Alloy Test-4. BCAT-4 will consist of two sets of samples referred to as BCAT-3 and 4 :Critical Point(BCAT-3-4-CP) and BCAT-4 : Polydisperse(BCAT-4-Poly).... The Binary Colloidal Alloy Test-3(BCAT-3) hardware supported three investigations in which ISS crews photographed samples of colloidal particles(tiny nanoscale spheres suspended in liquid) to document liquid/gas phase changes, growth of binary crystals, and the formation of colloidal crystals confined to a surface. Colloids are small enough that in a microgravity environment without sedimentation and convection, they behave much as atoms and so can be used to model all sorts of phenomena because their size, shape, and interactions can be controlled. The BCAT-3 payload consists of ten small samples of colloid alloys in which the microscopic colloid particles are mixed together into a liquid. These ten samples are contained within a small case that is the size of a school textbook. At the start of an experiment run, all ten samples are shaken to completely remix the colloid samples, much in the same way that salad dressing must be shaken to remix oil and vinegar. After the samples are mixed, what remains is periodically photographed using a digital camera until the colloid and liquid components of those samples have separated or the polymers have formed crystals. The samples can be remixed to repeat the experiment. The ten samples in BCAT-3 were selected as part of three separate experiments examining different physical processes :critical point, binary alloys, and surface crystallization.

Hennequin's prototype of a pneumatic tactile glove has layers of strategically placed air bladders that are rapidly inflated and deflated. The inventor claims that the size, location, and pressure of the tiny air bladders are the critical variables needed to create tactile illusions. By inflating the right patterns of bladders in the glove to the right amount of pressure, Hennequin hopes to be able to replicate the sensation of grasping an object and recognizing its shape. This is not the same kind of computerized glove that has dominated the VR story so far, although the ultimate goal is to combine a tactile glove with a gesture-sensing glove.

Subject field(s)
  • Chemistry
DEF

A subdivision of physical chemistry comprising the study of phenomena characteristic of matter when one or more of its dimensions lie in the range between 1 nanometre and 1 micrometre. The science includes not only finely divided particles but also films, fibers, foams, pores, and surface irregularities. It is the dimension that is critical, rather than the nature of the material. Colloidal particles may be gaseous, liquid, or solid, and occur in various types of suspensions(imprecisely called solutions), e. g., solid/gas(aerosol), solid/solid, liquid/liquid emulsion), gas/liquid(foam). In this size range, the surface area of the particle is so much greater that its volume that unusual phenomena occur; for example, the particles do not settle out of the suspension by gravity, and are small enough to pass through filter membranes. Macromolecules(proteins and other high polymers) are at the lower limit of this range.

OBS

Though the term is often used synonymously with surface chemistry, in a strict sense it is limited to the size range mentioned in at least one dimension, whereas surface chemistry is not.

Precipitation processes are complex.... Snow crystals begin as minute ice particles which have formed around condensation nuclei in the atmosphere. These nuclei may be dust particles with favorable molecular structure or even minute crystals of sea salt. If these ice particles exist in an atmosphere with an excess supply of water vapor(supersaturated air) they will continue to grow. Upon reaching a critical size, they begin to fall. Depending on the conditions they encounter in different layers of air during their descent, they may continue to grow, may stop growing, or may experience a succession of growth patterns. What arrives at the ground can be a simple product of the initial ice crystal formation, or it may be the result of a complex life history.
