Processes based on non-thermal plasma（NTP） for indoor air treatment inevitably lead to the formation of toxic by-products such as ozone（O3） and nitrogen oxides（NOx）. Adding a step of heterogeneous catalysis in series with NTP could allow for the decomposition of the by-products. Therefore, different catalysts were developed based on transition metal oxides, such as NiOx, CoOxand MnOxwith different weight percentage 1, 5 and 10 wt.%,deposited on a γ-Al2O3 support. The O3 removal efficiency（ORE） and the NOxremoval efficiency（NRE） were very encouraging in dry air： about 65% and 80%, respectively, by using2 g 5 wt.% MnOx/Al2O3 catalyst under the experimental conditions. However, strongly negative effects of relative humidity（RH） on the catalytic decomposition performance were observed. To overcome this limitation, the catalyst surface was modified to make it hydrophobic using a cost-effective chemical grafting method. This treatment consisted in impregnating the 5 wt.% MnOx/Al2O3 catalyst with different trichloro（alkyl）silanes（TCAS）.The effects of different linker lengths and amounts of TCAS for the hydrophobicity and the decomposition performance of surface-modified catalysts under humid conditions were investigated. Our results show that the surface-modified catalyst with the shortest linker and 0.25 mmol/gcatof modifying agent represents the best catalytic decomposition performance for O3. Its ORE is 41% at 60% RH, which is twice that of the non-modified catalyst.

Cold and dark periods have descended on Earth several times in geological history. One such period characterized the Cretaceous-Paleogene (K-Pg) boundary, following a meteor impact near Chicxulub in Mexico, about 66 million years ago, which caused dust, sulfate aerosols, and soot particles to be ejected into the atmosphere. This in turn led to a so-called “impact winter,” inhibiting photosynthesis and causing a global collapse of terrestrial and marine food webs, leading to the extinction of 60%–70% of plants and animals ( Alvarez et al., 1980 ). Different from animals that might still be able to find shelter and detritus food in a harsh environment, plants are sessile and require (lots of) light for photosynthesis. How did they survive in a time of prolonged darkness and decreasing temperatures ( Vellekoop et al., 2016 )?

The ideal lumbar and cervical discs should provide six degrees of freedom andtri-planar (three-dimensional) motion. Although all artificial discs are intended toachieve the same goals, there is considerable heterogeneity in the design oflumbar and cervical implants. The “second generation total disc replacements”are non-articulating viscoelastic implants aiming at the reconstruction ofphysiologic levels of shock absorption and flexural stiffness. This review aims togive an overview of the available implants detailing the concepts and thefunctional results experimentally and clinically. These monobloc prostheses raisenew challenges concerning the choice of materials for the constitution of theviscoelastic cushion, the connection between the components of the internalstructure and the metal endplates and even the bone anchoring mode. Newobjectives concerning the quality of movement and mobility control must bedefined.

Though Heidegger became a kind of conceptual companion of comparative philosophers,and a methodological example for interpreters of Daoist philosophy claiming that Zhuangzi or Laozi embodied the overcoming of Western“onto-theology,”Heidegger himself not only stressed his disbelief in the notion that Asian thinking could save the West from its“civilizational crisis”but also clearly claimed that Western thinking could emerge only through its distinction from the“mythical East.”However,at the same time,Heidegger criticized the decadence of the West,claimed the necessity of cultural rejuvenation,and then,with the failure of Germany to perform this task,seemed to turn to Chinese sources to find alternative *** to understand Heidegger’s complex relationship with China?Is Heidegger an Orientalist or an Occidentalist European philosopher?Moreover,how to understand the subtle and troubling connections between Heidegger’s complex relationship with China and Heidegger’s highly“problematic”(to say the least)intellectual engagement with Nazi ideology?To what extent are Orientalism and Occidentalism are linked to Heidegger’s belief in the Nationalist-Socialists’claims about“saving”the“European spirit”?

The flow inside a channel with surface mounted ribs is studied by numerical simulation and experimental flow visualization. Both the geometry with one rib and the geometry with two ribs, placed perpendicular to the flow, are studied, with particular emphasis on the effect of the variation of the distance between the ribs on the structure of the flow. Results show that, for Reynolds number flows of 400 and 1000 (based on the uniform incoming velocity and the height of the ribs), the flow reattaches between the ribs when they are separated by distances of 12h (h being the height of the ribs) and 6h, respectively. In this respect, however, the numerical results for the Reynolds number flow of 1000 are in contradiction with published results.

Effect of the simultaneous application of a high static magnetic field and a low alternating electric current on the solidification structure of pure aluminum has been investigated. Results show that the refinement of the solidification structure is enhanced by the electric current under a certain magnetic field. However,when the magnetic field intensity exceeds a certain value, the refinement is impaired under a certain electric current. The observation by electron backscattered diffraction(EBSD) shows the complex fields have led to the increase of the low angle boundaries with the refinement. Moreover, the application of the static gradient magnetic field is capable of modifying the distribution of the refined grains. The above results may be attributed to the formation of the cavities during the electromagnetic vibration process and the high magnetic field.
