“…63 During oocyte maturation, chemical inhibition or RNAi-mediated knockdown of ARP2/3 complex components causes failure of asymmetric division in murine 22,23 and porcine oocytes. 64 Recent studies provide a more detailed understanding of the role of ARP2/3 in oocyte maturation. Spindle migration includes 2 phases; the first slow phase mainly depends on the action of formin-2, whereas the second rapid migration phase involves ARP2/3-mediated actin polymerization.…”

Actin nucleation factors, which promote the formation of new actin filaments, have emerged in the last decade as key regulatory factors controlling asymmetric division in mammalian oocytes. Actin nucleators such as formin-2, spire, and the ARP2/3 complex have been found to be important regulators of actin remodeling during oocyte maturation. Another class of actin-binding proteins including cofilin, tropomyosin, myosin motors, capping proteins, tropomodulin, and Ezrin-Radixin-Moesin proteins are thought to control actin cytoskeleton dynamics at various steps of oocyte maturation. In addition, actin dynamics controlling asymmetric-symmetric transitions after fertilization is a new area of investigation. Taken together, defining the mechanisms by which actin-binding proteins regulate actin cytoskeletons is crucial for understanding the basic biology of mammalian gamete formation and pre-implantation development.

“…Therefore, an ammonia sensor with high response, good selectivity, long-term stability and low detection limit is critical and urgently needed. So far, various materials have been explored to detect NH3 gas, such as SnO2 [2][3][4][5], V2O5 [6], WO3 [7,8], Co3O4 [9,10], ZnO [11][12][13], TiO2 [14], carbon nanotubes [15,16], graphene [17,18], etc. However, the gas response using these materials is not high enough, and the detection limit of ammonia is above ppm level.…”

Accepted Manuscript Highlights The silica modified CeO2 nanostructures are synthesized using a sol-hydrothermal route and used as NH3 gas-sensing materials. At room temperature, the 8%silica-CeO2 based gas sensor shows high gas response of 3244% to 80 ppm of NH3 and lower detection limit (0.5 ppm) towards NH3 gas. The gas response of the NH3 sensor has good linear characteristics for NH3 gas detecting. The NH3 sensor exhibits good reproducibility, selectivity and long-term stability to NH3 gas. AbstractThe silica modified CeO2 gas sensing nanomaterials are synthesized using a sol-hydrothermal route. The 8%silica-CeO2 has larger specific surface areas of 83.75 m 2 /g and smaller crystalline size of 11.5 nm than pure CeO2, respectively. Compared to pure CeO2, the 8%silica-CeO2 based gas sensor exhibits significant enhancement 2 NH3 gas-sensing performance. At room temperature, it shows much better gas response of 3244% to 80 ppm of NH3 gas and lower detection limit (0.5 ppm) towards NH3 gas. It is also found that the gas response of the NH3 gas sensors increases linearly with the increase of NH3 gas concentration. Moreover, the NH3 gas sensor have good reversibility, stability and selectivity. The reason of enhanced NH3gas-sensing performance is not only because of the increased specific surface areas, but also due to the electrolytic conductivity of NH4 + and OH -on the surface.

Tungsten oxide (WO 3−x ) crystalline nano/microrods with identical morphology but different contents of oxygen vacancies were prepared by thermally evaporating fixed amount of WO 3 powder in reductive atmosphere from different amounts of S power at 1150 ∘ C in a vacuum tube furnace, in which both sources were loaded in separate ceramic boat. With increasing amount of S powder, a series of tungsten oxides, WO 3 , WO 2.90 , W 19 O 55 (WO 2.89 ), and W 18 O 49 (WO 2.72 ), could be obtained. And devices were fabricated by screen-printing the obtained WO 3−x crystals on ceramic substrates with Ag-Pd interdigital electrodes. With increasing content of oxygen vacancies, the devices fabricated with WO 3−x crystals present a negative to positive resistance response to relative humidity. Under dry atmosphere, for the devices with increasing , the strong response to light changed from short to long wavelength; under light irradiation, the conducting ability of the devices was enhanced, due to the more efficient separation and transportation of the photogenerated carriers; and under simulated solar irradiation, the photocurrent intensity of the W 18 O 49 device was roughly 8 times, about 500 times, and even 1000 times larger than that of the W 19 O 55 , WO 2.90 , and WO 3 one, respectively. With the versatile optoelectrochemical properties, the obtained WO 3−x crystals have the great potential to prepare various humidity sensors and optoelectrical devices.
