Si 3 N 4 ‐based nanocomposites containing 0–50 wt% TiC 0.37 N 0.63 are directly consolidated at 1700°C by spark plasma sintering, and their reciprocal sliding behavior against a Si 3 N 4 counterbody is investigated under a maximum Hertzian stress of 1.27 GPa in unlubricated conditions. The average grain widths of Si 3…
G factors [basic fibroblast growth factor (bFGF) and/or nerve growth factor (NGF)]-immobilized polycaprolactone (PCL)/ Pluronic F127 microspheres were prepared using an isolated particulate-melting method and the sequential binding of heparin and growth factors (GFs) onto the microspheres. The GFs immobilized on the m…
Micro-générateurs piézoélectriques pour des applications de récupération d'énergie Le sujet de ce travail de thèse s'inscrit dans la récupération d'énergie thermique à l'échelle microscopique pour proposer une alternative aux matériaux thermoélectriques. L'objectif est de concevoir, fabriquer et caractériser un récupé…
Die Motivation für diese Arbeit war die Optimierung des Ausdehnungsverhaltens von Fügeglaskeramiken für den Einsatz in Festelektrolyt-Brennstoffzellen und Hochtemperatur-Reaktoren, die eine hohe Wärmedehnung von Raumtemperatur bis 1000 °C erfordern. Hierfür wurden die richtungsabhängigen Wärmedehnungskoeffizienten (WD…
采用共沉淀的方法将含有一定比例的镍、钴、锰的金属醋酸盐溶液均匀混合，然后加入适当的沉淀剂Na2CO3制备前驱体Mn0.466Ni0.2Co0.2CO3，最后分别与不同锂源（Li2CO3、LiOH）混合煅烧得到富锂锰基Li1.133Mn0.466Ni0.2Co0.2O2正极材料。采用XRD和SEM分别对不同锂源制备的Li1.133Mn0.466Ni0.2Co0.2O2的结构和表面形貌进行表征，采用恒电流充放电和循环伏安法测试对不同锂源制备的Li1.133Mn0.466Ni0.2Co0.2O2的电化学性能进行测试。结果表明，以LiOH为锂源合成的样品在0.1C倍率下首次充、放电比容量分别为330.1mAh/g和218.6mAh/g，首…
Within the academic and industrial communities the selective oxi- dation of oxygen-containing organic compounds, such as alcohols, polyols, and aldehydes, primarily for the production of fine and specialty chemicals, remains a high priority. The main issue with the current industrial methods for these synthetic process…
在右n-凝聚环上研究Gorenstein n-余挠模的相关性质,证明了在右n-凝聚环上Gorenstein n-平坦模的Gorenstein n-余挠包络是Gorenstein n-平坦模,Gorenstein n-余挠模的Gorenstein n-平坦覆盖是Gorenstein n-余挠模;将n-余挠模的相关性质推广到Gorenstein n-余挠模上;在右n-凝聚环上讨论模和环的Gorenstein n-余挠维数的相关性质,给出了右n-凝聚环的左Gorenstein n-余挠整体维数与其他同调维数之间的一些等价刻画.
Cloaking a source via anomalous localized resonance (ALR) was discovered by\nMilton and Nicorovici in \\cite{MiltonNicorovici}. A general setting in which\ncloaking a source via ALR takes place is the settting of doubly complementary\nmedia. This was introduced and studied in \\cite{Ng-CALR} for the quasistatic\nregim…
Energy conversion processes involve losses. Specifically core losses, which are a result of the magnetization process in cored electrical energy conversion and storage devices. The cores are made of soft ferromagnetic materials that are easily magnetized and demagnetized. These soft magnetic cores, allow a reduction i…
This work is a contribution to the valorization of “Maltease peel”. The objectives of this research are (i) to study the efficiency of different extraction methods in terms of total phenol contents (TPC), total flavonoid contents (TFC), individual flavonoids (FI) and antioxidant activity of extracts and (ii) to examin…
Probe-based data storage attracted many researchers from academia and industry, resulting in unprecendeted high data-density demonstrations. This topical review gives a comprehensive overview of the main contributions that led to the major accomplishments in probe-based data storage. The most investigated technologies…
Abstract Intrinsically disordered proteins fail to adopt a stable three-dimensional structure under physiological conditions. It is now understood that many disordered proteins are not dysfunctional, but instead engage in numerous cellular processes, including signaling and regulation. Disorder characterization from a…
In this thesis, the results are reported of experimental studies in which oil, water and colloidal particles meet. Colloidal particles are particles that have at least one characteristic length scale in the range between a few nanometers (nm) and several micrometers (μm). Mixtures of oil and water, one finely disperse…
We realized that our 2013 publication describing Wnt6 knockout flies [1] contains a presentation error which does not impact any of the data or conclusions of the manuscript.
Even though continuous improvements have been seen in the analysis of flexible pavements, one of the most important factors is still oversimplified: the tire. This can result in costly decisions, such as poor structural road design, incorrect damage prediction, and inappropriate adoption of maintenance/rehabilitation…
In several electrical insulation components, such as cable connectors, joints and penetrators, various solid insulating materials are usually brought in contact, forming interfaces. The dielectric strength of these solid$|$solid interfaces is critical for the strength of the overall system. Especially in cases that th…
Compared to the traditional anonymous peer review process, open post-publication peer review provides additional opportunities -and challenges- for reviewers to judge scientific studies. In this editorial, we comment on the open peer review culture and provide some guidance for reviewers of manuscripts submitted to th…

Several reviews appeared in the last years to emphasize the unique properties showed by gold metal, when particle size falls in nanometers range. Au nanoparticles (NPs) have found uses in ceramics, medicine, and other areas. Among them the most exciting and growing field of application is undoubtedly catalysis. Histor…
