AbstractAbstract
[en] The purpose of the study was to examine the effect of activity-based nanoscience and nanotechnology education (ABNNE) on pre-service science teachers’ (PST’) conceptual understanding of nanoscience and nanotechnology. Within this context, the study was conducted according to mixed methods research with the use of both quantitative and qualitative methods. The participants were 32 PST who were determined by using criterion sampling that is one of the purposive sampling methods. ABNNE was carried out during 7 weeks as 2 h per week in special issues at physics course. Design and implementation of ABNNE were based on “Big Ideas” which was found in literature and provided guidance for teaching nanoscience and nanotechnology. All activities implemented during ABNNE were selected from literature. “Nanoscience and Nanotechnology Concept Test (NN-CT)” and “Activity-Based Nanoscience and Nanotechnology Education Assessment Form (ABNNE-AF)” were used as data collection tools in research. Findings obtained with data collection tools were discussed with coverage of literature. The findings revealed that PST conceptual understanding developed following ABNNE. Various suggestions for increasing PST conceptual understanding of nanoscience and nanotechnology were presented according to the results of the study.

AbstractAbstract
[en] Modern day microprocessor has increased remarkably in computational capacity which in turn has resulted in generation of higher heat fluxes. Air based conventional heat extraction systems are bungling to eradicate the aforesaid heat fluxes as the need of information technology and high computational facility is skyrocketing. In this present study, numerical simulation is carried out to analyze and compare the thermal performance of a heat pipe combined with forced convection heat transfer mechanism utilizing nanofluids in a mini channel heat sink for application in CPU cooling. Two phase heat transfer phenomenon employed in heat pipe can accomplish extreme heat removal rate. Temperature gradient along with thermal resistance between the coolant and mini channel heated wall is significantly reduced due to the application of nanofluids. Convective heat transfer coefficient at the condenser end of the heat pipe is noticeably improved with application of nanoparticles into distilled water. (author)

AbstractAbstract
[en] Here, we report quantitative measurements of nanoscale permittivity and conductivity using tuning-fork (TF) based microwave impedance microscopy (MIM). The system is operated under the driving amplitude modulation mode, which ensures satisfactory feedback stability on samples with rough surfaces. The demodulated MIM signals on a series of bulk dielectrics are in good agreement with results simulated by finite-element analysis. Using the TF-MIM, we have visualized the evolution of nanoscale conductance on back-gated MoS2 field effect transistors, and the results are consistent with the transport data. Our work suggests that quantitative analysis of mesoscopic electrical properties can be achieved by near-field microwave imaging with small distance modulation.

AbstractAbstract
[en] Incorporation of fulvic acid (FA) into the framework of hydroxyapatite particle to synthesis NHAP functionalized with FA (NHAP-FA) as a new smart nanocomposite is achieved. Some analytical methods such as EDX, FTIR, XRD, and TEM defined it. Preliminary study on the possible radiolabeling of NHAP-FA with 141,143Ce, 152,154Eu, 159,161Gd as represented radio-lanthanides that are gaining more attention in the last decades is carried out. The obtained results were revealed that a significant sorption affinity of radio-lanthanides (∼98%). Application on the environmental remediation towards the removal of some radionuclides (152,154Eu, 60Co, 99Mo, 63Ni and 137Cs) has been evaluated. (author)

AbstractAbstract
[en] Despite all predictions and promises, nanotechnology still seems to be more of an emerging science than a fully fledged revolution. More often than not, the patent system is blamed for this, supposedly tangling up nanotechnology in an impenetrable thicket of exclusionary rights instead of setting it free. Drawing on methods of complex network analysis, we provide empirical evidence suggesting that, at least in Europe, there is actually no patent thicket present in nanotechnology. Yet, the situation appears to be different in the USA.

AbstractAbstract
[en] Ferroptosis is a new type of programmed cell death, which is expected to become an important strategy of cancer treatment. Traditional strategies for inducing iron death are small molecule inducers based on biological agents. However, because of their poor water solubility, low cell targeting ability and fast metabolism in vivo, it is difficult for molecular drugs to play the long-acting role of ferroptosis induction. With the further study of ferroptosis and development of nanotechnology, nanomaterials have been proved to be more efficient drugs for inducing ferroptosis than those biological drugs. Therein, iron-based nanomaterials can directly release high concentrations of irons and increase reactive oxygen species levels in cells, which produce a better induction effect for ferroptosis. Whereas, it is challenging to differentiate nanoparticle-induced ferroptosis and traditional inducing strategies, elucidate the detailed mechanisms and further classify the synthetical methods of nanomaterials. For better guidance on the development of anticancer strategies, comprehensive summary of the latest developments of ferroptosis related nanomaterials, especially iron-based nanomaterials are in urgent need. In the paper, we summarized the main mechanisms of ferroptosis, highlighted the latest developments of nanomaterials for ferroptosis, and emphasized the advantages of iron-based nanomaterials for ferroptosis. The future prospect in this field was also discussed, paving the way for the related nanomaterials in the clinical cancer therapy. (topical review)

AbstractAbstract
[en] The use of nanotechnology in biomedicine involves the engineering of nanomaterials to act as therapeutic carriers, targeting agents and diagnostic imaging devices. The application of nanotechnology in cancer aims to transform early detection, targeted therapeutics and cancer prevention and control. To assist in expediting and validating the use of nanomaterials in biomedicine, the National Cancer Institute (NCI) Center for Biomedical Informatics and Information Technology, in collaboration with the NCI Alliance for Nanotechnology in Cancer (Alliance), has developed a data sharing portal called caNanoLab. caNanoLab provides access to experimental and literature curated data from the NCI Nanotechnology Characterization Laboratory, the Alliance and the greater cancer nanotechnology community.
