In-depth understanding of transport behavior of sulfided nano zerovalent iron/reduced graphene oxide@guar gum slurry: Stability and mobility.

Nanoscale zero-valent iron (NZVI), which has the advantages of small particle size, large specific surface area, and high reactivity, is often injected into contaminated aquifers in the form of slurry. However, the prone to passivation and agglomeration as well as poor stability and mobility of NZVI limit the further application of this technology in fields. Therefore, sulfided NZVI loaded on reduced graphene oxide (S-NZVI/rGO) and guar gum (GG) with shear-thinning properties as stabilizers were used to synthesize S-NZVI/rGO@GG slurries.

A new dual functional HS donor for fluorescence imaging and anti-inflammatory application.

This study explored FL-HS, a novel fluorescein-based HS donor, as an anti-inflammatory agent. The results demonstrated the efficient release of HS by FL-HS, along with its biocompatibility, real-time intracellular HS release and imaging capability. experiments using a rat model confirmed the anti-inflammatory effects of FL-HS, evidenced by reduced foot swelling.

Incubating green turtle (Chelonia mydas) eggs at constant temperatures: Hatching success, hatchling morphology and post-hatch growth.

Past studies applying constant-temperature incubation of eggs have involved all species of sea turtles, but rarely can we find a single one incubating eggs at three or more temperatures. Here, we incubated green turtle (Chelonia mydas) eggs from Ganquan Island, South China Sea, at five constant temperatures (26, 28, 30, 32 and 34 °C) to determine hatching success, incubation length and hatchling phenotype at each test temperature and temperatures optimal for embryonic development. Temperature affected hatching success, incubation length and all seven examined hatchlings traits, and clutch origin affected three (head length, fore-flipper length and hind-flipper length) of the seven.

Response surface design for removal of Cr(VI) by hydrogel-supported sulfidated nano zero-valent iron (S-nZVI@H).

In this study, a new sulfidated nanoscale zero-valent iron (S-nZVI) supported on hydrogel (S-nZVI@H) was successfully synthesized for the removal of chromium (Cr) (VI) from groundwater. The surface morphology, dispersion phenomenon and functional groups of novel S-nZVI@H were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy. Box-Behnken design (BBD) optimization technology based on response surface methodology (RSM) is applied to demonstrate the influence of the interaction of S-nZVI@H dose, initial Cr(VI) concentration, contact time, and initial pH with the Cr(VI) removal efficiency.

Specialized cockroach pollination in the rare and endangered plant Vincetoxicum hainanense in China.

Premise: Species of Apocynaceae are pollinated by a diverse assemblage of animals. Here we report the first record of specialized cockroach pollination in the family, involving an endangered climbing vine species, Vincetoxicum hainanense in China. Experiments were designed to provide direct proof of cockroach pollination and compare the effectiveness of other flower visitors.

Restoring wetlands outside of the seawalls and to provide clean water habitat.

In this study, we reported a practice at northern Hangzhou Bay, southeast China aimed at restoring coastal wetlands within the intertidal zone outside of the seawalls. The principle idea is protecting the site and helping the marsh establishment by engineering measures, and thereafter, relieving the protections to encourage the self-organization of the restored ecosystem. The results of this implementation showed the marsh reached an average vegetation cover of 70% in the first year.

Complete chloroplast genome of (Apocynaceae: Asclepiadoideae), an endangered liana endemic to China.

is an endangered liana species endemic to China. Habitat destruction coupled with difficulties in natural pollination has reduced its population size over time. As present studies have focussed more on breeding programmes instead of molecular aspects, here we reported on the complete chloroplast (cp) genome sequence of .

[Niche analysis of phytoplankton's dominant species in Dianshan Lake of East China].

By using modified Levins and Petraitis formulae, this paper determined the niche breadth and niche overlap of the phytoplankton's dominant species in Dianshan Lake of East China, and analyzed the relationships between the niche breadth and niche overlap and the density and dominance of the dominant species. The niche breadth and niche overlap of the dominant species differed in different periods, and different dominant species had different adaptive capacity to the environmental factors. Based on their niche breadth in different seasons, the dominant species in the Lake could be classified into four groups, among which, Chroomonas acuta and Chlorella vulgaris had broader niche, more quantity, wider distribution, and better use of environmental resources.

[Characteristics of phytoplankton community changes in Dianshan Lake during peak period of algal blooms].

Based on the investigation data of phytoplankton in Dianshan Lake from May to October in 2009, the characteristics of phytoplankton community and the dominant species succession are studied. The results show that Cyanophyta and Chlorophta are the main taxa. Cyanophyta is dominant in cell abundance and Chlorophta is dominant in species variety.

[Phytoplankton productivity and its influencing factors in Dianshan Lake].

To understand the relationship between the spatial-temporal variations of phytoplankton primary productivity and its environmental factors in Dianshan Lake, monthly survey was carried out from April, 2009 to March, 2010, with the method of white and black bottles. The result shows that seasonal variation of primary productivity (calculated according to carbon, following the same) is summer [0.95 g x (m3 x d)(-1)] > winter [0.

[Effect of Suining Tributary ecoremediation to all size-fractionated chlorophyll-a contents].

Through analysis of the size-fractionated chlorophyll-a contents in the remedied part, control part and non-remedied part in Suining Tributary, this paper discussed the effect of bioremediation to all size-fractionated chlorophyll-a contents. The averaged Chlorophy-a content of nano-plus pico-phytoplankton made up 85.232%, 92.
