“…5a-d, the trends of the most important tensile properties are reported, while the numerical results are summarized in Table 3. As it usually happens with nanofilled polymers [19,[33][34][35], an increase of the materials stiffness with the nanofiller amount can be observed, and the best results can be obtained by using exfoliated graphite nanoplatelets (see Fig. 5a).…”

In this work the mechanical and electrical behavior of poly(cyclooctene) (PCO)‐based nanocomposites were investigated. At this aim, different amounts (0.5–4 wt%) of carbon black (CB), carbon nanofibers (NF) and exfoliated graphite nanoplatelets (xGnP) were melt compounded with a PCO matrix and crosslinked with dicumylperoxide (DCP). The progressive increase of the DCP concentration led to an evident decrease of both the melting temperature and the crystallization temperature, and also the relative crystallinity was strongly reduced. Microstructural observations on nanocomposites materials with a DCP amount of 2 wt% evidenced how CB nanocomposites were characterized by a good nanofiller dispersion within the matrix, while NF and xGnP nanofilled samples presented a more aggregated morphology. The introduction of CB and xGnP determined an enhancement of the elastic modulus of the material, without impairing the ultimate properties of the pristine matrix. Electrical resistivity measurements evidenced how the prepared composites can be interesting as electro‐active materials for CB concentrations higher than 2 wt%. POLYM. ENG.

“…Conventionally, surface treatment is an effective approach to improve the corrosion resistance of metals and their alloys; hence, many techniques (electroless plating, chemical conversion, vapor‐phase deposition, and anodic oxidation) were applied for the surface treatment of Mg‐Li alloys 6–11. Unfortunately, possibly due to the reactivity of Li, the improvements of the corrosion resistance of the coatings fabricated by these techniques on Mg‐Li alloys are far from satisfaction, which promotes the attempts of new techniques.…”

Micro-arc oxidation (MAO) has been accomplished on Mg-Li alloy in alkaline polyphosphate electrolytes without and with the addition of 10 g/L K 2 TiF 6 . The surface/cross-section microstructures of the fabricated coatings were analyzed by scanning electron microscope (SEM); the compositions of the fabricated MAO coatings were analyzed by X-ray diffraction (XRD) and energy dispersive X-ray analysis (EDAX); the corrosion behaviors of bare and MAO coated Mg-Li alloys were evaluated using potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) in 3.5 wt% NaCl solution. Novel hybrid MAO coatings which showed hybrid composition of MgF 2 /Ti 2 O 5 /Ti 6 O 11 /MgO, as well as hybrid structure of a dense inner layer, a dense outer layer and an intermediate layer with some sealed/semi-sealed pores, had been fabricated on Mg-Li alloy in alkaline polyphosphate electrolytes with the addition of K 2 TiF 6 . Meanwhile, the corrosion resistance of the fabricated MAO coatings was improved obviously as the result of the addition of K 2 TiF 6 in the electrolytes. Moreover, the multiple roles of TiF 2-6 on the MAO process accounted for the fabrication of the corrosion-resistant hybrid MAO coatings.

“…The development of RS imagery has led to greater use of the digital photogrammetric method to produce DTMs because the RS data acquisition process is more efficient than traditional field survey methods. The VirtuoZo digital photogrammetry system, which was created by Chinese scholars, is famous worldwide (Zhang et al, 2000). Chinese scholars have also discussed the selection of features for image matching (Wang, 2005), quality controls for producing DTMs (Du, 2009;Long et al, 2011), and determining the resolution for expressing DTMs during the DTM construction process.…”

Geomorphometry, the science of digital terrain analysis (DTA), is an important focus of research in both geomorphology and geographical information science (GIS). Given that 70% of China is mountainous, geomorphological research is popular among Chinese scholars, and the development of GIS over the last 30 years has led to significant advances in geomorphometric research. In this paper, we review Chinese progress in geomorphometry based on the published literature. There are three major areas of progress: digital terrain modelling methods, DTA methods, and applications of digital terrain models (DTMs). First, traditional vector-and raster-based terrain modelling methods, including the assessment of uncertainty, have received widespread attention. New terrain modelling methods such as unified raster and vector, high-fidelity, and real-time dynamic geographical scene modelling have also attracted research attention and are now a major focus of digital terrain modelling research. Second, in addition to the popular DTA methods based on topographical derivatives, geomorphological features, and hydrological factors extracted from DTMs, DTA methods have been extended to include analyses of the structure of underlying strata, ocean surface features and even socioeconomic spatial structures. Third, DTMs have been applied to fields including global climate change, analysis of various typical regions, lunar surface and other related fields. Clearly, Chinese scholars have made significant progress in geomorphometry. Chinese scholars have had the greatest international impact in areas including high-fidelity digital terrain modelling and DTM-based regional geomorphological analysis, particularly in the Loess Plateau and the Tibetan Plateau regions.
