Cerebral death detects new method
Cerebral death is cerebral function is permanent lose, what this means human life is terminative. Nowadays, the organ that clinical organ transplants is great rely on cerebral death patient, its organ donates the organ that transplants for whole world organ to supply about 1/4. And in a few countries, evaluate a head to die to be mixed to resource of economic medical treatment for the economic burden that reduces patient family member very important also.
Be based on neurology examination with the accepted standard that dies at diagnosing a head. Use at diagnosing the index that the head dies to be in gradually to perfect at present, for example>6 hours check beforehand, what cannot go against is insensible with endocrine disorder. The ideal and auxiliary test that evaluates cerebral death needs contented blame to invade a gender, sensitivity, general usability, and seasonable and undertake in bedside easily. However, current test method is not accorded with all these standards.
Close infra-red spectrum (NIRS) is a kind of blame is invaded relatively gender, convenient, successive, cheap the new technology that the ground monitors cerebral blood to shed kinetic change. Close infra-red spectrum (NIRS) technology uses close infra-red smooth illuminate to organize, the diffuse reflection light in be being organized through the record and amendatory Beer-Lambert law come the haemoglobin chroma in mensurable organization. A group of researcher that come from China and United States saw the possibility that uses close infra-red spectrum to evaluate a head to die -- this is close infra-red spectrum before never by advised function.
They collected patient of 18 heads death and 20 health to get the data of close infra-red spectrum of the person that try, try to use a kind of custom-built portable close infra-red spectrometer to evaluate cerebral death.
Traditional cerebral death is evaluated complex, time-consuming, it is to invade a gender even and not quite reliable. NIRS technology is had blame invade gender, real time sex, can transplant gender, multi-parameter and operation are simple wait for an advantage, support by inspiratory agreement of FIO2 ‐ Varied O2. The application of this one success makes clear, straight adjacent and infra-red spectrum is measured different place is had between cerebral death patient and healthy person, namely Δ [HbO_2] and Δ [Hb] . This makes clear close infra-red spectrum (NIRS) technology is a kind of head death that has an outlook very much evaluates a method, with the groovy method such as electroencephalogram photograph comparing has definite advantage. "This research may die to evaluate a head and problem of barrier of other head function provides a kind of new method, " Ting Li of research group member says.

Through color change detects the detector of fire
Fire detector feels aerosol or quantity of heat sparks alarm, already was personnel warns below best circumstance scattered avoid the life that creates possibly and belongings loss. Accordingly, mix quickly accurate testing system and avoid false alarm dispute to often need.
It is current that the real time, fire that is based on video is explored the most reliable call the police technology, it uses the feature of camera identifying aerosol and fire. However, the phase before this technology is burning identifies the fire that is about to begin -- consider from safe angle, optimal is combustion early days identifies of course.
In nature, the change of temperature can cause change of certain biologic color. A common example is catabolism of the chlorophyll when autumn brings about plant lamina to be from green change yellow, gules, orange or brown. Below the inspiration that metabolizes in chlorophyll, the researcher of lab of project of country of material of Sichuan university environmental protection high polymer developed change of color of a kind of support to indicate the fire that quantity of heat accumulates to explore a method.
This method uses a kind to be based on adjacent benzene the sensor of van body element of 2 armour nitrile (PMS) , the phthalein Jing that this sensor forms hot stability in left and right sides of 180 ° C (PC) , the environmental temperature that great majority of this temperature outclass uses daily, but wait for the ignition temperature that can burn material under lumber and high polymer material. Accompanying to the chemical change of PC from PMS change to green color from white.
On this foundation, the fire early-warning package that they developed a kind to be based on pattern recognition algorithm (EWC) , realized the real time monitoring of fire early warning system. Compare with photograph of naked eye observation, this algorithm shortened significantly the noise of EWC is in season. Spark inside 20 seconds when 275 ° C alarm, detect inside 3 seconds bright fire, before making this equipment is burning, mix the level after combustion is significant.

But the glow that erasure rescripts is filmy
Heart is tired this the simple plastic film that Professor Reineke of technical university and his group studied to ply is less than 50 μ M, it is thinner than head give back of the person. They introduced organic glow element in these transparent plastic film.
At the beginning, these elements are in a kind of not active dark position. Pass illuminate of local use ultraviolet ray, can be change of this kind of dark status active glow position.
Illume of model of attack by surprise or laser write activation to be able to presswork to the design on foil, its resolution and common laser printer comparative. Be similar to the glow paster in darkness, the news that takes pattern can be read when design gives off light. And through infra-red lamp illuminate OK and complete erasure labels, keep new data.
These but process designing is transparent the working principle of label is: The oxygen element in plastic film is met from inside glow element " take secretly " light energy, shine element does not give off light, and ultraviolet radiate can cause chemical reaction, the oxygen in effectively cleared layer, accordingly, glow element is activationed and can give off light.
And the temperature that uses infra-red light to bring about foil is elevatory, bring about the addition with osmotic oxygen thereby, make the layer fills oxygen again thereby, for glow element glow abrupt destroys process, so but erasure.
These novel label can produce any size. Every square metre does not make to the low cost of material of two euro its have wide application: Such as the number of form code, serial application that hopes to be able to conceal information, by need to numerate. In addition, these sightless label can mix the security of the file prevent bogus to raise a brand-new level.
Professor Reineke considers further:
"These are invisible and the label application perspective that can rescript is very wide, these label that we make are thinner than a traditional form code. It is a lot of commonly used information replace kind another kind of interactive technology probably. These glow marks may make electronic equipment is storing information field is washed out. The development of these systems and optimize open up an extensive research field, develop material with interdisciplinary means, craft project and basic research union are together. Craft project and basic research union are together..

Polychromatic force sends glow material
Force sends glow (ML) material is in such as monitor, in waiting for modern technology, man-made skin and stress sensor produce main effect. But at present force sends glow material only and finite kind of color.
Publish on Advanced Materials, the Bolong Huang of college of industry of Hong Kong grain is taught and Professor Feng Wang of the Dengfeng Peng of Shenzhen university and college of Hong Kong city and its work in the same placing excogitated a kind of current method that can enlarge ML to launch limits.
ML material fastens elemental ion activation with lanthanum, ion of lanthanum department element is gone to by conformity oxygen sulfide crystal (CaZnOs) in, show arrive from purple the intense ML property of close infra-red area.
Below mechanical power effect, ML material accumulates exterior charge through triboelectricity effect, cause space charge departs and reunite, the energy that caused photon to launch a form is released.
The ML fluorescent material of impure lanthanum, every kinds have distinctive color, can use at generation to impose the close pattern that prevent bogus. If use different ML material number, that can pass indication different color to be extracted add secret information.
Professor Bolong Huang: "Impure CaZnOS shows strong polychromatic ML to blast off in fluorescent material, its intensity and typical CZOS: Mn material comparatives. The high-powered ML mechanism that through density functional theory computation studied this job is medium, namely the CaZnOS crystal with lanthanum department impure element. We still established a kind of method, through adjusting Tb3+– Mn2+The scale of impure CZOS fluorescent material, accurately control gives off light to gules ML from green color. Bright polychromatic ML material is prevented in the bank huge latent capacity is had on bogus and safety application.

Use at the organic photoelectricity diode with artificial embedded retina
World each district is counted with 1 million plan the person suffers from retina to retreat travel sex disease, if retinal pigment is metamorphic,mix age dependency yellow spot is metamorphic. Sensitive cell degrades gradually, the eyesight that causes different level is lost.
Come for years, electronic retina is false the odd retinal nerve that body uses report to stimulation is received and organize visual message because of its yuan the tremendous potential that shows extensive diplopia strength.
The retina of smooth hot season that put forward first 2012 is false body by composition resembling element, these independence resembling element work, pulse light changeover is become spark the pulse electric current of nerve activity. The photograph of retinal helper art with the power supply outside traditional eye is compared, it is thin that Guang Fuzhi enters thing thin and wireless, operation procedure is quite simple.
In this system, the patient is wearing the video blinkers of camera, camera is handled by portable computer, project on retina. Every smooth hot season resembles element near infra-red (NIR) light is changed into voltaic pulse, pass stimulation to small electrode and retinal network convey his and spread nerve cell next.
Flexible the development infuse that the newest progress of electronic technology is this one domain new vitality. Come from dust because of Huo Wen Ren é Professor Janssen of industrial university designed an agile platform, the sheet that this platform is based on solution to handle writtens guarantee and establish ties organic photoelectricity diode (OPD) , compositive splash shoot nitrogen to change titanium (TiN) arouse and return electrode.
They combine experimental result, imitate small electrode and OPDs are like element in physiological saline environment pulse is close infra-red (the function below NIR) illume.
Pass the comparison of pair of odd form OPD and series connection OPD, card palpability can be in two kinds this like element pulse offers imitate nerve below close infra-red light yuan needs charge, and electrode dimension is only lesser (the total charge that the OPD ability of ~35 μ M) covers every pulse nerve to stimulate the window, because its have taller open circuit voltage (VOC~1.4V) .
The open up of art of rehabilitate of high resolution retina that this research is future road, but the challenge that art of these rehabilitate of high resolution retina still face a variety of projects to go up with biology.
