Abstract Hypothesis: Strongly degraded cellulosic artworks usually need deacidification and consolidation. Alkaline nanoparticles are known to be effective in neutralizing the acidity, while cellulose nanocrystals have the potential to be used as compatible and effective strengthening agents. Experiments: We have grafted cellulose nanocrystals with oleic acid using a CDI-mediated procedure, to increase their dispersibility in organic solvents, and synthesized Ca(OH)2 or CaCO3 nanoparticles via a...

Abstract Hypothesis A liquid droplet is apt to be deformed within a compact space in various applications. The morphological change of a droplet and vapor accumulation in the confined space between two parallel surfaces with different gaps and surface wettability are expected to significantly affect the evaporation dynamics of the squeezed droplet therein. Experiments Here the evaporation dynamics of a squeezed droplet between two parallel hydrophobic/superhydrophobic surfaces are experimentally...
Abstract Hypothesis Macroporous polyampholyte hydrogels, simultaneously bearing both the anionic and cationic groups, demonstrate immense promise over the one-sign charged polyelectrolytes, owing to a unique phenomenon known as the ˝anti-polyelectrolyte˝ effect. Thus, they are extremely promising materials, since they remain solvated and functional even in harsh conditions. Furthermore, macroporous morphology significantly enhances polyampholyte response to external stimuli, since it accelerates...

Abstract The PbO2 electrodes of lead-acid batteries are normally applied as the positive electrodes in lead-carbon hybrid capacitors. However, the effective utilization rate of active materials in the electrodes is only about 12.5 %, leading to a low energy density of lead-carbon hybrid capacitors. In this paper, a nano-SiO2 doped PbO2 electrode was prepared by the co-electrodeposition method. The energy density of the lead-carbon hybrid capacitor using a nano-SiO2/PbO2 electrode can reach 61 Wh...

Abstract The effect of Pd loading (0.25, 0.5 and 1.0 wt%) and ZrO2 support calcined at diverse temperatures (600, 700 and 800 °C) by pyrolysis of UiO-66 was investigated for CO oxidation in this work, respectively. The physicochemical properties of the samples were characterized by various characterization methods. The XRD results exhibited that all ZrO2 support possessed mixed crystalline phase, the monoclinic ZrO2 and tetragonal ZrO2. And the calcination temperature had a big impact on the com...

Abstract Through direct addition of inorganic zinc ions into the solution of indium phosphide quantum dots (InP QDs) at ambient environment, we here present a facile but effective method to modify InP QDs for photocatalytic hydrogen evolution from hydrogen sulfide (H2S). X-ray diffraction patterns and transmission electron microscopic images demonstrate that zinc ions have no significant influence on the crystal structure and morphology of InP QDs, while X-ray photoemission spectra and UV-Vis di...

Abstract A novel self-supported structure of Ce-UiO-66/TNF was firstly synthesized by growing Ce-UiO-66 on a TNF substrate. This novel Ce-UiO-66/TNF material was proved to possess a high supercapacitive performance in the redox electrolyte of Fe(CN)63-/4-, and it was also the first study for Ce-UiO-66 material on the supercapacitor application. High specific capacitances of 6.9 and 2.5 Fcm-2 can be achieved at large current densities of 20 and 80 mAcm-2, respectively. After 10000 charge-discharg...
Abstract Hypothesis Recently, we reported a three-dimensional phase diagram for the gelation of cationic tripeptide glycylalanylglycine (GAG) in water–ethanol mixtures. We showed that the gel strength reaches an optimum for a peptide concentration of 200 mM and ethanol/water mixtures with ca. 55–60 mol% ethanol. An increase of the ethanol fraction causes a substantial upshift of the gel’s softening temperature which is indicative of a reduced peptide solubility. We expect the formation of long c...
Abstract Disordered carbons derived from biomass are herein efficiently used as an alternative anode in lithium-ion battery. Carbon precursor obtained from cherry pit is activated by using either KOH or H3PO4, to increase the specific surface area and enable porosity. Structure, morphology and chemical characteristics of the activated carbons are investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetry (TG), Raman spect...

Abstract Exploitation of novel photocatalysts for highly efficient degradation of organic dyes and reduction of hexavalent chromium is of significance to reduce environmental pollution. Herein, a novel three-dimensional flower-like Bi2S3 nanocrystals composed of two-dimensional Bi2S3 nanosheets were prepared by one-pot hydrothermal method with polyvinyl pyrrolidone (Mw = 1300000) as a capping agent. The experimental results show that polyvinyl pyrrolidone has evident enhanced effect on the photo...
