Seaweeds are macroalgae growing under marine ecosystems and it plays diversified roles in human life. Different types of seaweeds are available and among them, the widely used ones for extraction are brown seaweeds. One of the significant plants bio-stimulants with a wide range of applications in horticulture and agriculture is seaweed extract (SE). Various methods are employed for their extraction process. The bioactive composition of SE varies according to the type or species of seaweeds and methods of extraction. It has got almost similar effects as that of phytohormones. Seaweed extract application alone or in combination with other bio-stimulants or nutrients during different crop stages are being practised in a broad group of fruit crops (temperate, sub-tropical and tropical fruit crops). An array of research studies has also revealed that the usage of seaweed extracts is more environmentally friendly owing to their organic nature and cost-effectiveness. It has proven significant improvements on growth, yield, quality, storage and stress tolerance. Hence, the use of seaweed extract at the appropriate time and right concentration to a variety of fruit crops can support the industry's overall growth.
Geostationary satellite‐based 6.7 μm band best water vapor information layer analysis over the Tibetan Plateau

Published: April 2016

AbstractThe best water vapor information layer (BWIL) of the 6.7 μm water vapor absorption infrared (IR) band for the FengYun‐2E is investigated over the Tibetan Plateau with standard atmospheric profile and European Centre for Medium‐Range Weather Forecasts (ECMWF) operational model analysis data. The sensitivity tests show that surface characteristics over the Tibetan Plateau have a significant influence on the BWIL. To be specific, topographic elevation, colder skin temperature, and lower emissivity tend to lift the altitude of the BWIL, decrease its magnitude, and narrow the half‐width range. The results from statistical analysis indicate that the altitude of the BWIL reaches the highest in summer and the lowest in winter. Meanwhile, the altitude of the BWIL is highly correlated with the water vapor amount above 500 hPa over the Tibetan Plateau and above 300 hPa over the East China Plain, respectively. The diurnal variation in the BWIL is synchronous with the diurnal variation in the surface skin temperature. It can be concluded from the study that surface characteristics over high terrain in dry and cold atmospheres have more significant impacts on the BWIL. With multiple water vapor absorption IR bands, the imagers on board the new generation of geostationary satellites will provide crucial improvement in water vapor remote sensing over the current single water vapor band on board the FY‐2 series according to the analysis in this study.
Unusual Regioselectivity in the Gold(I)‐Catalyzed [3+2] Carbocycloaddition Reaction of Vinyldiazo Compounds and N‐Allenamides
Authors: López Enol , González Javier , López Luis A. 
Published: April 2016

AbstractThe reaction of N‐allenamides with alkenyl diazo compounds in the presence of gold catalysts provided methylidenecyclopentene derivatives resulting from a formal intermolecular [3+2] carbocyclization, a rare process in the gold chemistry of allenes. The participation of the CαCβ bond of the allenamide represents a very unusual regioselectivity in gold‐catalyzed cycloaddition reactions of this type of allenic scaffolds. A stepwise mechanism involving initial activation of the diazo component has been proposed.magnified image

Authors: Xu Jing‐Kun , Wang Yong , Gu Yonghong , Tian Shi‐Kai 
Published: April 2016

AbstractAn unprecedented stereospecific allylation reaction of nitroacetates with enantioenriched primary allylic amines has been developed. A range of nitroacetates smoothly underwent allylation with enantioenriched primary allylic amines in the presence of a palladium catalyst and boric acid followed by one‐pot decarboxylation to afford structurally diverse homoallylic nitro compounds in good to excellent yields with excellent retention of configuration. On the other hand, the allylation followed by denitronation provided a facile synthetic route to optically active β‐chiral γ,δ‐unsaturated esters.magnified image
Local Unfolding of Fatty Acid Binding Protein to Allow Ligand Entry for Binding
Authors: Xiao Tianshu , Fan Jing‐song , Zhou Hu , Lin Qingsong , Yang Daiwen 
Published: April 2016

AbstractFatty acid binding proteins are responsible for the transportation of fatty acids in biology. Despite intensive studies, the molecular mechanism of fatty acid entry to and exit from the protein cavity is still unclear. Here a cap‐closed variant of human intestinal fatty acid binding protein was generated by mutagenesis, in which the helical cap is locked to the β‐barrel by a disulfide linkage. Structure determination shows that this variant adopts a closed conformation, but still uptakes fatty acids. Stopped‐flow experiments indicate that a rate‐limiting step exists before the ligand association and this step corresponds to the conversion of the closed form to the open one. NMR relaxation dispersion and H‐D exchange data demonstrate the presence of two excited states: one is native‐like, but the other adopts a locally unfolded structure. Local unfolding of helix 2 generates an opening for ligands to enter the protein cavity, and thus controls the ligand association rate.

Published: April 2016

AbstractHydrogen storage is a primary challenge for using hydrogen as a fuel. With ideal hydrogen storage kinetics, the weak binding strength of hydrogen to sorbents is the key barrier to obtain decent hydrogen storage performance. Here, we reported the rational synthesis of a methyllithium‐doped naphthyl‐containing conjugated microporous polymer with exceptional binding strength of hydrogen to the polymer guided by theoretical simulations. Meanwhile, the experimental results showed that isosteric heat can reach up to 8.4 kJ mol−1 and the methyllithium‐doped naphthyl‐containing conjugated microporous polymer exhibited an enhanced hydrogen storage performance with 150 % enhancement compared with its counterpart naphthyl‐containing conjugated microporous polymer. These results indicate that this strategy provides a direction for design and synthesis of new materials that meet the US Department of Energy (DOE) hydrogen storage target.

AbstractIngenious approaches to supramolecular assembly for fabricating smart nanodevices is one of the more significant topics in nanomaterials research. Herein, by using surface quaternized cationic carbon dots (CDots) as the assembly and fluorescence platform, anionic sulfonatocalix[4]arene with modifiable lower and upper rims as a connector, as well as in situ coordination of Tb3+ ions, we propose an elaborate supramolecular assembly strategy for the facile fabrication of a multifunctional nanodevice. The dynamic equilibrium characteristics of the supramolecular interaction can eventually endow this nanodevice with functions of fluorescent ratiometric molecular recognition and as a nano‐logic gate with two output channels.
