A workshop was held in 1990 in Muscle Shoals, Alabama to discuss current and future research on phosphorus in agriculture. Twenty four presentations were given in areas ranging from basic to applied research. For five of the research areas presented at the workshop, this paper presents a literature review, a review of presentations at the workshop, and a discussion of future research ideas.Presented at the FAO/IAEA Consultants meeting on Evaluation of the Agronomic Effectiveness of Phosphate Fertilizers Through the use of Nuclear and Related Techniques, May 10-12, 1993 相似文献

环境友好催化技术发展趋势 总被引:8,自引:2,他引:6
20世纪发展的用以消除排放污染物的环境友好催化剂技术将在本世纪得到广泛重视并将应用于汽车及静态污染源。贫燃发动机的燃油效率高、温室气体排放量低。但贫燃条件下NOx 的还原对催化工作者提出了更大的挑战。催化传感器在监测汽车及静态污染源排放方面将扮演更为重要的角色。在 2 1世纪初期 ,运用被动催化技术 (passivecatalytictechnology)分解大气中的臭氧将得到更多的应用。光催化继续成为人们研究的主要对象之一 ,但其应用市场仍有待开发。在电催化及从碳氢化合物制造氢的燃烧过程研究中 ,对质子交换膜燃料电池的研究将成为一个主要的焦点。同时 ,低能耗、低污染的化学品生产技术仍将是制造商们追寻的目标 ,并将取得更大的成就 相似文献

Electrohydrodynamic drying (EHD) is a promising technology to dehydrate biomaterials but needs further development for industrial use. Open questions in our understanding of EHD drying are discussed. These include the phenomena driving the EHD drying process, possible dryer configurations for industrial upscaling, and the specific energy consumption of corona discharge and peripheral equipment. Future opportunities for experimental and numerical analysis of EHD drying are also highlighted, including particle image velocimetry and X-ray/neutron tomography. Numerical modeling of EHD airflow and the associated vapor transport, coupled with the transfer processes within the drying material, are considered essential for further process optimization. 相似文献

Theranostics involves finding the biomarkers of a disease, fighting them through site specific drug delivery and following them for prognosis of the disease. Microneedle array technology has been used for drug delivery and extended for continuous monitoring of analytes present in the skin compartment. We envisage the use of microneedle arrays for future theranostic applications. The potential of combining microneedle array-based drug delivery and diagnostics as part of closed-loop control system for the management of diseases and delivery of precision drugs in individual patients is reported in this paper. 相似文献

The development of biomaterials that can be used to substitute metals in dental restorations represents the main challenge of future research activities until the year 2020. Therefore, the authors will focus on the presentation of two types of biomaterials for dental restoration: glass-ceramics and sintered ceramics. Dental biomaterials must have a highly aesthetic appearance that is comparable to that of natural teeth. Furthermore, they must be more durable than natural teeth and show good mechanical properties at ambient temperatures.Based on the state of the art and the latest research activities, the presentation is focused on glass-ceramics with high toughness, glass-ceramics with optical properties comparable to those of natural teeth and glass-ceramics that are processed with preferred techniques, for example, those which are moulded on different types of high-strength substrate materials. In addition, high-strength and high-toughness materials such as lithium disilicate glass-ceramics can be processed either by moulding or by a new method, that is, machining. Possible directions will be presented for moulding different types of glass-ceramics such as fluoroapatite containing glass-ceramics on high-toughness substrates made of glass-ceramics or very tough sintered ceramics.The focal point of this presentation is the demonstration of the high-strength and high-toughness sintered ceramics of the ZrO2 type. The preferred processing method of this type of biomaterials for dental restoration is machining using CAD/CAM technologies. Future activities will be focused on improving the quality of the ZrO2-type biomaterial. At present ZrO2 ceramics are white opaque. One of the main aims is to achieve optical properties comparable to those of natural teeth in ZrO2 ceramic. Therefore, the material has to be developed in special dental colours with the same mechanical properties and good durability as that of the white ZrO2. The authors will show future directions for developing coloured ZrO2 sintered ceramics.Future research activities will be focused on gaining a better understanding of the phenomena and mechanisms of toughening glass-ceramics and ceramics. With the acquired knowledge on the toughening mechanisms, new directions for developing ceramics until the year 2020 will be explored. The technology to achieve this goal will be applied nanotechnology. 相似文献
