Coating Mechanism of AuNPs onto Sepiolite by Experimental Research and MD Simulation

The amenability of gold nanoparticles (AuNPs) coating on natural and modified (hexadecyl trimethyl ammonium bromide, CTAB) sepiolite surfaces was studied both experimentally and theoretically. The zeta potential experiments and Fourier transform infrared spectrophotometer (FTIR), environmental scanning electron microscope (ESEM), and transmission electron microscopy (TEM) analyses were carried out with the sepiolite samples in the presence of AuNPs. In addition, the adsorption of three gold-nanoparticles on the sepiolite surface (100) in the absence and presence of CTAB was investigated by molecular dynamics (MD) simulations. The AuNPs showed no significant change in the zeta potential of natural sepiolite surfaces due to negative charges of both the sepiolite and AuNPs at natural pH. The surface charge of modified sepiolite decreased with the increase in AuNPs concentration indicating the significance AuNPs adsorption. FTIR, ESEM, and TEM analyses indicated the coating of AuNPs onto the modified sepiolite surface were higher than that of the natural sepiolite surface. The MD simulation results showed that AuNPs can easily adsorb onto the basal surface of the sepiolite due to its hydrophilicity in the presence and absence of CTAB as indicated in the experimental studies. In short, the modification of sepiolite with CTAB made the charge positive, and in turn considerably increased the AuNPs coating on sepiolite surfaces due to electrostatic attraction.

Knockdown of SALL4 inhibits the proliferation, migration, and invasion of human lung cancer cells in vivo and in vitro

Background: This study aimed to investigate the SALL4 expression in lung cancer, determine if SALL4 regulates the biological functions of lung cancer cells at the cellular level, and clarify the possible mechanisms involved. Methods: Immunohistochemistry was used to detect the SALL4 expression messenger RNA (mRNA) in 62 cases of lung cancer tissue microarray. The correlation of SALL4 with the clinical pathological parameters and overall life cycle of patients and the impact of disease-free life cycle was analyzed. Reverse transcriptionpolymerase chain reaction (RT-PCR) and western blotting were used to detect the SALL4 expression in lung cancer cell lines and nude mouse models. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, colony-forming assay, and flow cytometry were used to detect the effects of interference with SALL4 expression on lung cancer cell proliferation and transplant tumor models; the effect of interference with SALL4 expression on the growth of transplanted tumors in vivo was also examined. Results: SALL4 was highly expressed in lung cancer tissues and cell lines and was closely related to the patient’s TNM stage and lymph node metastasis. Compared to patients with a high SALL4 expression, those with a lower SALL4 expression had a longer overall and disease-free survival. The expression of SALL4 is an independent risk factor for the prognosis of lung cancer patients. Interference with SALL4 expression can significantly inhibit cell proliferation and clonal formation. Interfering with the expression of SALL4 can arrest the cells in the G0/G1 phase by inhibiting the expression of the cell cycle-related proteins, cyclin B, cyclin E, and cyclin D1. Furthermore, wound-healing and Transwell assays showed that interference with SALL4 expression could significantly inhibit the migration and invasion of lung cancer cells, while experiments in nude mice showed that interference with SALL4 expression could significantly inhibit the size and weight of transplanted tumors. Conclusions: SALL4 was highly expressed in lung cancer cell lines. Interference with the expression of SALL4 can effectively inhibit the proliferation, migration and invasion of lung cancer cells, promote cell cycle arrest, and play the function of tumor suppressor genes. SALL4 may be a new target for the diagnosis and treatment of lung cancer.

Enhanced chain packing achieved via putative headgroup ion-triplet formation in binary anionic lipid/cationic surfactant mixed monolayers

Lipid/surfactant miscibility was investigated in monolayers composed of binary mixtures of dipahnitoylpho-sphatidylglycerol (DPPG) and dihexadecyldimethylammonium bromide (DHDAB). Langmuir monolayers formed from biomimetic DPPG/DHDAB mixtures based on the anionic:cationic lipid ratios observed in the bacterium Staphylococcus aureus (7:3 and 1:1) were examined alongside those of the pure amphiphiles and a surfactant rich 3:7 mixture. Using a combination of GIXD, TRXF and IRRAS, DPPG/DHDAB 1:1 monolayers were found to form a more stabilised condensed phase compared to pure DPPG, which was composed entirely of electrostatically neutral ion pairs, analogous to the so-called catanionic amphiphiles spontaneously formed by single-chain surfactants with opposing headgroup charges. Despite the lack of lateral charge repulsion the ion paired phase of DPPG/DHDAB exhibited slightly looser chain packing that was observed for DPPG indicating a significant steric effect on packing geometry caused by ion pair formation. Surprisingly, the 7:3 mixture of DPPG/DHDAB formed a completely condensed phase, with no isotherm transitions, in which the chain packing was significantly closer than was found for either DPPG or the totally ion paired monolayer. It is postulated that this mixture forms a distinct DPPG/DHDAB/DPPG ion triplet phase in which the overall negative charge is delocalised across the headgroups. Vesicles composed from the 7:3 mixture formed highly stable dispersions with an increased gel to liquid crystalline phase transition temperature with respect to its pure components. Increasing the proportion of DHDAB above 50 mol% led to demixing between the condensed ion paired phase and the more fluid surfactant, as was clearly observed in epifluorescence images taken of the surface films.

High energy density and high working voltage of a quasi-solid-state supercapacitor with a redox-active ionic liquid added gel polymer electrolyte

To increase the energy density of quasi-solid-state supercapacitors, a redox-active gel polymer electrolyte (GPE) was prepared by evaporating the excess water in a neutral gel that consists of polyvinyl alcohol (PVA), Na2SO4 and the ionic liquid (IL) N-butyl-N-methylpyrrolidinium bromide (Pyr(14)Br). The influence of IL Pyr(14)Br on the ionic conductivity of GPE was investigated. The maximum ionic conductivity of PVA-Na2SO4-Pyr(14)Br GPE can reach 27.1 mS cm(-1). The optimized GPE was assembled with two activated carbon electrodes into a quasi-solid-state supercapacitor. The electrochemical performances of this supercapacitor were evaluated by cyclic voltammetry, galvanostatic charge/discharge, electrochemical impedance spectroscopy and self-discharge measurements. The assembled supercapacitor exhibits a high energy density of 33.0 W h kg(-1), which is due to the wide working voltage (2.0 V) as a result of the strong solvation of Na+ cations and SO42- anions and the production of an additional pseudocapacitive contribution from the Br-/Br-3(-) redox reaction at the electrolyte/electrode interface. This supercapacitor exhibits outstanding cyclic stability with an 81.0% capacitance retention ratio after 8000 charge/discharge cycles. Moreover, this supercapacitor presents good self-discharge behavior.

Adsorption removal of Ni(II) and phenol from aqueous solution by modified attapulgite and its composite hydrogel

Attapulgite (ATP) and its organically modified products have been investigated for potential applications in environmental remediation. In this work, a variety of modifiers with different functional groups, including saturated sodium chloride solution (NaCl), cetyltrimethyl ammonium bromide (CTAB) and humic acid (HA), were used to treat attapulgite clay firstly, and then with the modified ATP as adsorbent and acrylamide (AAm) as monomer, polyacrylamide/modified attapulgite (PAAm/modified ATP) composite hydrogel which could adsorb heavy metal ions Ni(II) and organic pollutants phenol were synthesized. The structure of the raw ATP and modified ATP was specified with Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and Transmission electron microscope (TEM). The experiments indicated that the modified ATP and composite hydrogel possessed good adsorption properties for Ni(II) ions and phenol. The adsorption capacity of PAAm/HA-ATP hydrogel for Ni(II) was as high as 64.3 mg/g, which was 194.9% of pure hydrogel. The adsorption isotherm of HA-modified ATP (HA-ATP) and adsorption kinetics of PAAm/HA-ATP composite hydrogel was particularly concerned. The adsorption isotherm equation fitted well on the Langmuir model and R-L values ranged from 0.04 to 0.12 with different temperatures, indicated that the HA-ATP was a suitable adsorbent for adsorption of Ni(II) ions from wastewater. The obtained kinetics data for Ni(II) ions adsorption onto the PAAm/HA-ATP were described well by the pseudo-second-order model (R-2 > 0.99). As for the adsorption of phenol, double-modification proved to be the most effective method, and its optimal adsorption capacity was obtained on PAAm/CTAB-HA-ATP hydrogel.

Effects of deuteration on the structure and magnetic properties of bis-quinolinium tetrabromidocuprate(II) dihydrate

The partially [d(6), 2] and fully [d(20), 3] deuterated analogues of (QuinH)(2)CuBr4 center dot 2H(2)O (d(0), 1) were prepared and their crystal structures were determined [Quin = quinoline]. In both compounds, there is a clear disorder in the positions of the bromide ions which was resolved. This led to a reexamination of the structure of the parent, fully protonated compound (1) where a small percentage of previously unrecognized disorder was also observed and the structure rerefined. Variable temperature magnetization measurements over the range 1.8-310 K indicate that all three materials behave as magnetically well-isolated layers that can be evaluated using the 2D-quantum Heisenberg antiferromagnetic model. Final fitting results for the partially (J = -5.96(5) K) and fully (J = -5.77(2) K) deuterated compounds indicate slightly weaker exchange compared to the protonated compound (J = -6.17(3) K), likely as a result of the increased disorder in the deuterated phases.

Regenerated keratin-encapsulated gold nanorods for chemo-photothermal synergistic therapy

Gold nanorods (AuNRs) have been widely applied to photothermal therapy against cancer. However, the chemically synthesized AuNRs such as that via seed-mediate method usually demonstrated a high cytotoxicity due to the existence of cetyltrimethylammonium bromide (CTAB) coating. In this work, keratin, a family of cysteinerich structural fibrous proteins was used for the first time to encapsulate AuNRs by a simple mixing method. Compared with CTAB-AuNRs, the keratin-encapsulated AuNRs (AuNRs@Kr) showed an improved colloid stability and good biocompatibility including low cytotoxicity and hemolytic effect. Moreover, AuNRs@Kr exhibited great potential as drug carriers with redox-responsive drug release behavior, due to the high concentration of disulfide crosslinking in keratin coating, and the DOX-loaded AuNRs@Kr demonstrated higher chemo-photothermal synergistic therapy efficiency against 4T1 cells compared with either free DOX or AuNRs@ Kr alone, suggesting a promising nanoplatform for cancer therapy.

Anticancer and apoptotic activity of biologically synthesized zinc oxide nanoparticles against human colon cancer HCT-116 cell line- in vitro study

Aim of this study was to synthesize the safe and stable zinc oxide nanoparticles (ZnONPs) from the leaves of Artocarpus heterophyllus. The alter in the color of the leaf extract dark brown upon addition of zinc nitrate Zn(NO3) confirms the formation of Zinc Oxide nanoparticles (ZnONPs). UV-VIS spectrophotometric analysis showed lambda max at 235 nm while Fourier transform infra-red (FTIR) spectroscopy showed various amines and amides are involved in the stabilization of ZnONPs. Energy dispersive X -rays (EDX) confirms the presence of zinc. Transmission electron microscopy (TEM) analysis revealed particle size ranges from 12 to 24 nm. These observed characteristic of nanoparticles are extremely useful in anticancer activities against HCT-116 colon cancer cell line. These ZnONPs showed IC50 value at 20 mu g/ml while on normal Vero cell line showed less effective by MTT assay. Furthermore, these nanoparticles were evaluated for apoptotic activity by acridine orange/ethidium bromide (AO/EB) double staining method showed the membrane blebbing and chromatin condensation.

Effects of microstructured surface and mixed surfactants on the heat transfer performance of pulsed spray cooling

Pulsed spray cooling is a highly promising method for efficiently cooling high heat flux electronic components. In this study, the factors affecting the heat transfer performance of pulsed spray cooling were investigated on a closed pulsed spray cooling experimental system. It was found that a straight fin microstructured surface has a higher heat transfer performance than a smooth surface, but it decreases the surface temperature uniformity. Based on this, the effects of binary mixed surfactants, DuPont Capstone FS-31:Tween 20, FS-31:sodium dodecyl sulfate (SDS), and FS-31:cetyltrimethylammonium bromide (CTAB), on the heat transfer performance and surface temperature uniformity of pulsed spray cooling with a microstructured surface were investigated. The results show that the surface tension and contact angle of 75% FS-31:25% CTAB were the lowest and the heat transfer performance was the highest. The mean surface temperature was 47.26 degrees C and the heat transfer coefficient was 2.02 W/(cm(2)K). Compared with the results without surfactants on microstructured surface, the mean surface temperature was lower by 8.43 degrees C and the heat transfer coefficient was higher by 35.57%. The mixed surfactants greatly improved the temperature uniformity of the microstructured surface, and the maximum surface temperature difference decreased from 1.587 degrees C to 0.471 degrees C.
