4城市湖泊生态改造设计显示文摘转通湖泊驳岸技术是使用混凝土和浆砌石材料来建造硬质直立式驳岸结构为达到固土目标,但是硬化混凝土驳岸系统已经破坏了湖泊水生态和自然景观。湖泊生态化改造是通过土木工程结合生态技术,强化湖泊的自身防止污染功能,同时提高了湖泊生态多样性及水体自能力[1]。该研究通过调研越南荣市气候、环境特点与南湖污染现状,提出了湖泊驳岸生态化改造设计方案。Tang Van Tai Tran Ngoc Binh Nguyen Nhu Anh Phan Hong Nhung 2016安徽农学通报2016,22,23:1
5Jahn-Teller distortion assisted interstitial nitrogen engineering:Enhanced oxygen dehydrogenation activity of N-doped Mn_(x)Co_(3-x)O_(4) hierarchical micro-nano particles显示文摘Rational design of earth-abundant transition metal oxides catalysts is highly desirable for developing sustainable chemical processes.Herein,we demonstrate a prospective interstitial nitrogen engineering for fabricating oxygen vacancies(OVs)-rich nitrogen-doped-Mn_(x)Co_(3-x)O_(4)(N-Mn_(x)Co_(3-x)O_(4))oxide catalyst,in which the ratio of OVs concentration of N-Mn_(x)Co_(3-x)O_(4)to Mn species is as high as 1:1,according to the characterizations of X-ray absorption(XAS)and X-ray photoelectron(XPS)spectroscopies.The promising strategy of interstitial nitrogen engineering through lattice distortion caused by the Jahn-Teller effect can significantly increase the amount of interstitial nitrogen.The resulting catalyst enables an additive-free aerobic dehydrogenation coupling of aromatic amine to afford azo compounds with>99%yield and>99%selectivity at 60☆.We observed the superb catalytic activity is promoted by the enhanced oxygen mobility in OVs,which were created by the interstitial nitrogen in the catalyst matrix.The presence of interstitial nitrogen in transition metal oxides in this study shows how the manipulation of catalyst matrix can increase the OV sites to promote aerobic oxidation reaction.Yangxin Jin Fengfeng Li Peixin Cui Yun Yang Qingping Ke Minh Ngoc Ha Wangcheng Zhan Fei Ruan Chao Wan Zhao Lei Van Noi Nguyen Wei Chen Jun Tang 2021Nano Research2021,14,8:1
6A new species of the genus Leptolalax (Anura: Megophryidae) from southern Vietnam显示文摘We describe a new species of megophryid frog from Phu Yen Province in southern Vietnam. Leptolalax macrops sp. nov. is distinguished from its congeners by a combination of the following morphological attributes:(1) body size medium(SVL 28.0–29.3 mm in three adult males, 30.3 mm in single adult female);(2) supra-axillary glands present, creamy white; ventrolateral glands indistinct;(3) tympanum externally distinct;(4) dorsal skin roughly granular with larger tubercles, dermal ridges on dorsum absent;(5) rudimentary webbing present between fingers Ⅰ–Ⅱ and Ⅱ–Ⅲ; rudimentary webbing between all toes; fingers and toes without dermal fringes;(6) in life ventral surface greyish-violet with white speckling;(7) supratympanic fold distinct, dark brown in life;(8) iris bicolored, typically golden in upper half, fading to golden green in lower half;(9) tibia short(TbL/SVL 0.44–0.45 in males); and(10) eyes large and protuberant(ED/SVL 0.15–0.16 in males).From all congeners for which comparable sequences are available, the new species differs markedly in the 16 S rRNA mitochondrial gene sequence(P-distance>5.7%). The new species is currently known only from montane evergreen tropical forests of Song Hinh District, Phu Yen Province, and M'Drak District of Dak Lak Province at elevations of 470–630 m a.s.l.. We suggest the new species should be considered as Data Deficient following the IUCN's Red List categories. We also report a previously unknown Leptolalax mt DNA lineage from an evergreen tropical forest in the Hoa Thinh District of Phu Yen Province,which may also represent an undescribed species.Tang Van Duong Dang Trong Do Chung Dac Ngo Truong Quang Nguyen Nikolay A.

9Revealing efficient catalytic performance of N-CuO_(x) for aerobic oxidative coupling of aliphatic alkynes:A Langmuir-Hinshelwood reaction mechanism显示文摘O_(x)idative couplings of aliphatic alkynes are crucial for the production of naturally occurring 1,3-diynes.Herein we report the novel approach for effective synthesis of unsaturated coordinated N doped copper oxides(N-CuO_(x))catalyst,and uncover that N-CuO_(x) catalyst as an additive-free and cost-effective heterogeneous catalyst has highly catalytic performance for directly oxidative coupling of aliphatic alkynes.The key to achieve efficient oxidative coupling of aliphatic alkynes is the synergistic effect of N species and uncoordinated O/Cu species caused by N dopants,which undergoes the Langmuir–Hinshelwood reaction mechanism.The N-CuO_(x) catalyst displays~89.1%yield for hexadeca-7,9-diyne under mild conditions and stable reusability(5 cycles),showing significant advances compared with the traditionally copper oxides.These findings highlight the heteroatom dopants that provide a new methodology for designing efficient copper catalysts in synthesis of naturally occurring 1,3-diynes.Jun Tang Bowen Jiao Wei Chen Fei Ruan Fengfeng Li Peixin Cui Chao Wan Minh Ngoc Ha Van Noi Nguyen Qingping Ke 2022Nano Research2022,15,7:0

11亚热带多雨区生态护岸结构与效能研究——以荣市前门河道为例显示文摘传统护岸工程大量使用浆砌石、钢筋混凝土等材料建造成直立式结构,给河流水环境、生物群落等带来了诸多不利影响。以越南荣市的前门河道为研究对象,针对前门河道的水生态特征与河道岸边环境、土壤条件,设计并建造了抛石型和石笼型两种生态护岸形式。通过为期1年的香根草生长状况跟踪监测,提出了一种适用于亚热带多雨区的生态护岸植被,通过Miseq高通量测序实验测定了生态护岸微生物群落多样性,揭示了其生态净水机理。Tang Van Tai 李奎鹏 Tran Ngoc Binh Nguyen Nhu Anh 2016黑龙江生态工程职业学院学报2016,29,6:0
12Using Visual MODFLOW Model to Assess the Efficiency of Subsurface Barrier Wall for Groundwater Flow Regulation and Reduction of Saline Intrution显示文摘Barrier walls effectively store water,regulate underground flows,improve exploitable reserves and prevent saltwater intrusion.The effectiveness of the underground barrier wall depends not only on the hydrogeological structure,the technical parameters of the wall but also on the layout scheme of the exploitation well system.The results showed that in natural conditions,the ground water level upstream of the barrier wall rose in the presence of a barrier wall.In wells located downstream of high barrier walls,the water level decreased.The amount of underground current flowing into the sea decreased,the annual average value of the whole region decreased was 316 m3/day and night.In presence of a wall,both the water level and the amount of evaporation increased.The average increase in evaporation volume during the calculation period of ten thousand days with walls was 4.114 m3/d.So in presence of a wall,the amount of water that can be exploited increases by the total amount of evaporation plus the decrease in discharge to the sea and is equal to 4,424 m3/d.In the exploitation condition,if the water level in the presence of wall is kept as low as in the absence of wall,the exploitation flow will increase to about 4,400 m3/day and night.From the calculated water level values when there is a wall and without a wall,we can see that if the exploitation flow in presence of a wall and in the absence of wall is the same,the water level drop at the calculated observation wells upstream of the wall will decrease from 0.21 m to 3.97 m.The condition of effective exploitation of the wall depends on the mining scheme.The exploitation scheme is reasonable,the exploitation flow of the wells does not exceed the allowable flow so as not to cause the drying of the aquifer at the location of the well.The upstream area of the wall reflects quite clearly as the Total dissolved solids content in observation wells upstream of the wall at the end of the calculation time is significantly reduced compared to that without the wall,ranging from 69 mg/L to 5,629 mg/L.In the presence of a wall,the water level of observation wells upstream of the wall is higher than that of without a wall from 0.10 m to 0.74 m.Nguyen Minh Khuyen Doan Van Long Nguyen Tien Bach Tang Huu Dong Bui Cong Du Dang Dinh Phuc 2021Journal of Environmental Science and Engineering(A)2021,10,3:0
