[科学研究和技术服务业] [2015-08-29]
Spintronics is the advanced branch of nanoelectronics making use of specially engineered materials that can impart spin functionality in the electrons, in addition to its well-known property of charge. Spin field effect transistor (spin-FET) is a spin-device consisting of ferromagnetic source and drain electrodes to impart spin-functionality into the device with the spin field effect transistor action realized with an electric field applied through the gate voltage. The whole concept relies on controlling the spin precession from source to the drain through a spin-conducting channel by applying a voltage on the gate region. An interesting class of materials is the half-metallic ferromagnetic compounds having majority spin density of states at the Fermi level (E_F) showing metallic behaviour, while minority spin density of states at a certain gap below the E_F. CrO_2 is such a half-metallic oxide with theoretical predicted 100% degree of spin-polarization and high Curie temperature (T_C) of ~395 K making it appropriate for spin-device applications. Hence, nanotechnology is the technology of the future, giving rise to the design of new kinds of materials (electronic & magnetic) and devices based on them, all set to revolutionize the world.

Biometrics authentication is a process by which an individual’s identity is authenticated by evaluating one or more unique biological traits, such as voice recognition, palm geometry, DNA identification, gait recognition, fingerprint matching, facial recognition, iris recognition, signature verification, and vein recognition. It was introduced based on the behavioral and physiological characteristics of an individual, which is difficult to be duplicated. Considered to be more reliable compared to physical devices and numeric codes, biometrics involves verification and identification processes to authenticate an individual. Verification is a one-to-one matching process that is used to verify the biometrics traits of an individual against a particular template in a database.

2743.全球干细胞脐血UCB市场报告(2015-2019年)
[医药制造业,科学研究和技术服务业] [2015-08-22]
UCB is the blood that remains in the placenta and the attached umbilical cord after childbirth. Cord blood contains stem cells that are unique, smart, and capable of treating several lifethreatening diseases. They are used in the treatment of hematopoietic and genetic disorders. The placental blood can produce ten times more stem cells compared to the umbilical cord, which can in turn be used for the treatment of an adult patient. The cord blood, which is collected during childbirth, is stored and cryopreserved. The cord blood can be stored at private cord blood banks or public cord blood banks. This preserved blood can be used for transplantation and the treatment of diseases at the later stages of life.

Bio-implants are medical devices made up of biomaterials used for the repair, replacement, and augmentation of damaged tissues, particularly for the treatment of orthopedic and cardiovascular conditions. Orthopedic bio-implants are used in replacement procedures for the hip, spine, knee, and other extremities such as the shoulder, wrist, elbow, and ankle. Cardiovascular bio-implants include CRM devices, stents, and prosthetic heart valves.

MPS is a service offered by a third-party provider to optimize and manage an organization's document environment. MPS manages an organization's objectives such as reducing cost, improving the prolific imaging and printing environment, and improving efficiency and productivity. It involves monitoring, regulating, and improving the printing sub-structure of an organization. Under an MPS structure, the service provider has to take primary responsibility for fulfilling the end-user printing needs, which include printing equipment, supplies, service, and the management of the printer fleet. The provider needs to track the usage of the printer fleet and the problems occurring with it. Also, the provider needs to analyze the business data that have been gathered in managing the printer usage.

Medical records include clinical, office, consultation, and evaluation notes; laboratory, X-ray, operation, patient progress, physical, and pathology reports; and discharge records. The conversion of these data, received through dictation by tape, digital system, or voice files from physicians, into text format is called medical transcription. A professional involved in the process of conversion is called a medical transcriptionist. These processed data are used as documents or records for further reference, presurgical exams, liability insurance, and disability claims. Medical transcription requires a high degree of training, proficiency in English, and a deep knowledge of medical terminologies. Medical transcription is cost-effective and reduces physicians' time and the duration of the documentation process.

A military flight simulator is a device that artificially re-creates aircraft flight and various aspects of the flight environment. Flight simulators are categorized into two types: FFS and FSTD. An FFS is a replica of a specific type or model and series of an aircraft cockpit, whereas an FSTD is a replica of flight controls and devices. There are four levels of FFS, i.e., levels A-D, with level D being the highest standard and providing acceleration in all six DOF. A flight simulator covers simulation in three areas, i.e., aircraft, environment, and cueing simulation.

2750.静电磁激纤维纳米复合材料的制备及在生物医学中的应用
[科学研究和技术服务业,医药制造业] [2015-08-05]
Materials capable of responding to external stimuli including pH, temperature, magnetic and electric field, undergoing conformational changes are considered to be one of the most exciting and emerging classes of advanced materials receiving considerable scientific interest especially in the biomedical field. Stimuli-responsive polymers in the form of micro- or nanofibers have received great attention during the last 10 years and have been exploited in a diverse range of biomedical applications such as drug delivery, tissue engineering, bioseparation and biosensing. One of the most popular and versatile fiber fabrication methods used for the production of fibers is electrospinning. Its simplicity, cost-effectiveness and applicability not only to pristine synthetic and natural polymers but also to composites, enables the development of polymer-based fibrous nanocomposites via the combination of polymers with inorganic nanofillers. Among such nanoadditives, magnetic nanoparticles capable of interacting with an externally applied magnetic field, are particularly attractive owing to their potential biomedical applications including magnetically-triggered drug delivery, magnetic cell seeding, magnetic bioseparation, hypothermia cancer treatment and contrast enhancement in magnetic resonance imaging. In this chapter, an introductory section on electrospinning and on different parameters influencing this process is initially provided. The different fabrication routes for generating electrospun magnetoactive polymer-based (nano)fibrous materials are briefly discussed and finally the applicability of these materials in the biomedical field including tissue engineering, drug delivery, hypethermia treatment and biosensing is reviewed.
