The results show that the use of nanotechnology and nano materials can be an effective method to improve the performance of dental composite resins in a various ways. At last, the paper also discusses the perspective about the dental composite resins.展开更多

Nations that have carried out the R＆D of nanotechnology are extending a great amount of effort in this area and have already gained some significant achievements. At present, there has been more R＆D in the development of RMs than that of the toxicity of nanomaterials. In this paper, the current research status of nanoscale RMs around the world is introduced. Finally, the research strategy and suggestion for domestic nanoscale RMs are provided based on the recent research in nanotechnology.展开更多

Furthermore, this innovative method will cost down at high technology nano-Fab especially for 28 nanometer process. Through the theoretical study and numerical simulation, we predict the best permutation for mitigating EMI noise from three-phase electric power lines system without any shielding system down to 1.2 mG in 3.0 m distance from applying I = 50 A at 60 Hz with 12 series cable tray system. Followed above discussions, this study indicated different and new perspectives with before opinions of some researcher. The measured magnetic field values on the nano-Fab are in good agreement with this simulation results. These good results give more confident to apply in new building nano-Fab system. Furthermore, this innovation will cost down for EMI shielding at high technology nano-Fab especially for 40 （and below） nanometer process.展开更多

With creativity, nanotechnology looks for increasingly smaller spaces in nature to meet the needs and interests of the individuals and of the society. Considering that the researches aim to create techniques to move and combine atoms and molecules, a question arises, how will these atoms and molecules behave in the new arrangement. This is the great challenge and this article attempts to bring some benefits to the subiect. It also intends to bring the human sciences, particularly law, to the scenery of this scientific revolution. The lack of regulatory frameworks does not allow humans to search and produce anything without limits. Thus, human rights should be considered an ethical foundation for nanotechnology discoveries, as they represent the ＂rights＂ that, at least, humans should have respected.展开更多

At the same time, insurers, reinsurers, insurance, and reinsurance brokers in search of the relevant value of their services in the eyes of insured and long-term benefits are increasingly paying attention to the possibilities of nanotechnology. On one hand, insurers see unlimited possibilities of nanotechnology in preventive and repressive activity in relation to losses. The obstacle in this case, for high-tech companies, is stiff competition from companies which are not innovation leaders, but with the necessary influence and power at the international and national market. On the other hand, understanding the reasons for the application of nanotechnology in the conflict prevention activities of the insurer allows him to develop and implement a more flexible strategy for sustainable development of the business.展开更多

Such releases might lead to unwanted exposure. The dissolution of NMs at nano-bio interfaces is one of the most noteworthy causes of the toxicity of dissolvable NMs. A growing number of studies are focusing assessing NMs dissolution during exposure tests. This mini review considers recent developments in the quantitative tools for the assessment of NMs dissolution, and highlights the critical points in the evaluation of the toxicity of dissolvable NMs.展开更多
