| 1 | Environmental application of three-dimensional graphene materials as adsorbents for dyes and heavy metals: Review on ice-templating method and adsorption mechanisms显示文摘The remediation of wastewater requires treatment technologies which are robust, efficient,simple to operate and affordable such as adsorption. Lately, three-dimensional(3D)graphene based materials have attracted significant attention as effective adsorbents for wastewater treatment. The intrinsic properties of 3D graphene structure such as large surface area and interconnected porous structure can facilitate the transport of pollutants into the 3D network and provide abundant active sites for trapping the pollutants. For the synthesis of 3D graphene structure, ice-templating is commonly practiced due to its facile steps, cost effectiveness and high scalability potential. This review covers the icetemplating fabrication technique for 3D graphene based materials and their application as adsorbents in eliminating dyes and heavy metals from aqueous media. The assembly mechanisms of the ice-templating fsynthesis are comprehensively discussed. Further discussion on the fundamental principles, critical process parameters and characteristics of ice-templated 3D graphene structures is also included. A thorough review on the mechanisms for batch adsorption of dyes and heavy metals is presented based on the structures and properties of the 3D graphene materials. The review further evaluates the dynamic adsorption in packed columns and the regeneration of 3D graphene based materials. | Kar Chiew Lai Lai Yee Lee Billie Yan Zhang Hiew Suchithra Thangalazhy-Gopakumar Suyin Gan | 2019 | Journal of Environmental Sciences2019，31，5： | 13 |
| 2 | Adsorption characteristics of humic acid-immobilized amine modified polyacrylamide/bentonite composite for cationic dyes in aqueous solutions显示文摘Humic acid-immobilized amine modified polyacrylamide/bentonite composite (HA-Am-PAA-B) was prepared and used as an adsorbent for the adsorption of cationic dyes (Malachite Green (MG), Methylene Blue (MB) and Crystal Violet (CV)) from aqueous solutions. The polyacrylamide/bentonite composite (PAA-B) was prepared by intercalative polymerization of acrylamide with Nabentonite in the presence of N,N-methylenebisacrylamide as a crosslinking agent and hexamethylenediammine as propagater. PAA-B was subsequently treated with ethylenediammine to increase its loading capacity for HA. The surface characterizations of the adsorbent were investigated. The adsorbent behaved like a cation exchanger and more than 99.0% removal of dyes was detected at pH range 6.0-8.0. The capacity of HA-Am-PAA-B was found to decrease in the following order: MG > MB > CV. The kinetic and isotherm data were interpreted by pseudo-second order rate equation and Freundlich isotherm model, respectively. Experiments were carried out using binary solute systems to assess the competitive adsorption phenomenon. The experimental isotherm data for each binary solute combination of MG, MB and CV were analyzed using Sheindrof-Rebhun-Sheintuch (SRS) (multicomponent Freundlich type) equation. | T. S. Anirudhan P.

| 3 | CSN1 inhibits c-Jun phosphorylation and down-regulates ectopic expression of JNK1显示文摘CSN1 is a component of the COP9 signalosome(CSN),a conserved protein complex with pleiotropic functions in many organs and cell types.CSN regulates ubiquitinproteasome dependent protein degradation via the deneddylation and the associated deubiquitination activities.In addition,CSN associates with protein kinases and modulates cell signaling,particularly the activator protein 1(AP-1)pathway.We have shown previously that CSN1 suppresses AP-1 transcription activity and inhibits ultraviolet(UV)and serum activation of c-fos expression.Here we show that CSN1 can inhibit phosphorylation of proto-oncogene c-Jun product and repress c-Jun dependent transcription.Further,CSN1 dramatically downregulates ectopic expression of c-Jun N-terminal kinase 1(JNK1)in cultured cells.The decline in JNK1 is not caused by excessive proteolysis or by 3′UTR-dependent mRNA instability,but by CSN1-dependent repression of one or multiple steps in transcriptional and posttranscriptional mechanisms.Thus,in contrast to CSN5/Jab1,which promotes AP-1 activity,CSN1 displays a negative effect on the AP-1 pathway.Finally,we discuss about the dynamic equilibrium of the CSN complexes in regulation of the AP-1 pathway. | Tomohiko Tsuge Suchithra Menon Yingchun Tong Ning Wei | 2011 | Protein & Cell2011，2，5： | 2 |

| 18 | Design of bio-oil additives via molecular signature descriptors using a multi-stage computer-aided molecular design framework显示文摘Direct application of bio-oil from fast pyrolysis as a fuel has remained a challenge due to its undesirable attributes such as low heating value,high viscosity,high corrosiveness and storage instability.Solvent addition is a simple method for circumventing these disadvantages to allow further processing and storage.In this work,computer-aided molecular design tools were developed to design optimal solvents to upgrade bio-oil whilst having low environmental impact.Firstly,target solvent requirements were translated into measurable physical properties.As different property prediction models consist different levels of structural information,molecular signature descriptor was used as a common platform to formulate the design problem.Because of the differences in the required structural information of different property prediction models,signatures of different heights were needed in formulating the design problem.Due to the combinatorial nature of higher-order signatures,the complexity of a computer-aided molecular design problem increases with the height of signatures.Thus,a multi-stage framework was developed by developing consistency rules that restrict the number of higher-order signatures.Finally,phase stability analysis was conducted to evaluate the stability of the solvent-oil blend.As a result,optimal solvents that improve the solvent-oil blend properties while displaying low environmental impact were identified. | Jia Wen Chong Suchithra Thangalazhy-Gopakumar Kasturi Muthoosamy Nishanth G.Chemmangattuvalappil | 2022 | Frontiers of Chemical Science and Engineering2022，16，2： | 1 |
