An organic–inorganic hybrid superlattice with near perfect synergistic integration of organic and inorganic constituents was developed to produce properties vastly superior to those of either moiety alone. The complementary hybrid superlattice is composed of multiple quantum wells of 4-mercaptophenol organic monolayers and amorphous ZnO nanolayers. Within the superlattice, multichannel formation was demonstrated at the organic–inorganic interfaces to produce an excellent-performance field effect transistor exhibiting outstanding field-effect mobility with band-like transport and steep subthreshold swing. Furthermore, mutual stabilizations between organic monolayers and ZnO effectively reduced the performance degradation notorious in exclusively organic and ZnO transistors.

In order to investigate the variation of Summer Monsoon (SM) during Tropical Cyclone(TC) acitivityin the Vietnam’s East Sea (VES), we have used the ERA Interim reanalysis data to evaluate the variant of SM intensityin two areas at three levels (1000mb, 850mb and 700mb). The first area(0 - 100N; 105-1100E) was used to examine the change of wind from Australian High and the second area(5 - 150N; 90 - 1050E)was used to analyze the change of wind from Mascarene High. These variations are investigated towards two characteristics: (1) Anomaly of wind compared with mean value and (2) Appearance frequency of wind in each value range. The resultsshowthat SM intensityduring TC activity in the VESis less dependent on the time of year. SMI is stronger from 30% up to 85% of the mean values. In addition, during TC activity in the VES, frequency of SMI gets the maximum valueat the range of VTB - 1,5VTB or 1,5VTB - 2VTB with the total of frequency from 55% to 75%. Key words: Variations of Summer Monsoon; Tropical Cycloneactivity in the Vietnam’s East Sea.

This study goal is to explore Changes of the temperature field during storms and Effects of Cold Air on Structure of Thermal Fields in Typhoons. Typhoons are a kind of tropical cyclone that often occur on tropical or subtropical sea surfaces where the sea surface temperature is higher than 26.5 ◦C (HU et al, 2000). The results show that When affected by cold air, the hot core structure in the storm is broken. Temperature tends to increase gradually from west to east and from north to south. Temperatures in the northern and western regions were still lower than in the center of the storm, but in the eastern and southern areas of the center of the storm, the temperature was higher than in the center of the storm. Near the surface, below 800hPa, the temperature of the center of the storm is also lower than the average temperature of the areas around the center of the storm (except for typhoon Kammuri). The decrease in temperature in the lower central region and areas north and west of the center of the storm is due to the intrusion of the CA. This result demonstrates the role of cold air to the structure of the temperature field in the storm. However, further explanations are needed for the distribution of the maximum hot cores in the center of the storm.

116Mối quan hệ giữa lượng mây và bức xạ sóng dài đi ra tại đỉnh khí quyển trên khu vực Nam Bộ Tóm tắt: Dựa trên số liệu OLR và lượng mây có độ phân giải 1,0×1,0 độ kinh vĩ của NCEP/NCAR trong thời kì 1981 -2012, mối quan hệ giữa lượng mây và bức xạ sóng dài đi ra tại đỉnh khí quyển (OLR) trên khu vực Nam Bộ đã được xem xét thông qua việc phân tích, so sánh đặc điểm phân bố không gian, biến đổi theo thời gian và mối quan hệ tương quan giữa chúng. Kết quả cho thấy rằng, đặc điểm phân bố và diễn biến trong năm của lượng mây và OLR là ngược nhau, khu vực hoặc thời gian có lượng mây lớn thì OLR nhỏ và ngược lại. Trên khu vực Nam Bộ, OLR thường có giá trị lớn trong mùa khô và trong các năm El Nino, song trong các năm La Nina và trong mùa mưa thì lại có giá trị nhỏ. Trong thời kỳ 1981-2012, OLR trên khu vực có xu thế giảm khoảng 3,6 W/m 2 /thập kỉ, còn lượng mây lại có xu thế tăng khoảng 0,2%/thập kỉ. Từ khóa: Lượng mây, bức xạ sóng dài đi ra, Nam Bộ.Abstract: Using 1,0 0 ×1,0 0 resolution data of the Outgoing Longwave Radiation (OLR) and the cloud cover from NCEP/NCAR during the 1981 -2012 period, the relationship between the cloud cover and the OLR in the Southern of Vietnam was investigated by analyzing and comparing the spatial distribution, temporal evolution and their correlation. The results show that the characteristics of the spatial distribution and the year cycle of cloud cover and OLR are inversely correlated. The region or time that the cloud cover is great, the OLR is small and vice versa. In the Southern of Vietnam, the OLR value is largest (or smallest) in the dry (or rainy) season and in the El-Nino (La-Nina) years. In addition, during the 1981-2012period, the OLR in this region shows a downward trend about 3.6 W/m2/decade, while the cloud cover tends to increase by 0.2%/decade.
