Butterfly wings have the ability to directionally control the movement of water microdroplets. However, the realization of artificial directional sliding biosurfaces has remained challenging. Inspired by butterfly wings, a new kind of directional patterned surface is developed to achieve superhydrophobicity and anisot…
The present work recommends the pre-treatment of rice straw to reduce its silica and/or wax for using commercial UF adhesive rather than the more expensive MDI. This is the most successful and appropriate route for the production of RS-based composites. The utilization of rice straw is highly economic, and will help t…
A novel Fe <sub>3</sub> O <sub>4</sub> –CuO@meso-SiO <sub>2</sub> composite was fabricated as a magnetically recyclable and efficient catalyst for olefin epoxidation.
A composite cathode based on redox-stable La0.2Sr0.8TiO(3+δ) (LSTO) can perform direct carbon dioxide electrolysis; however, the insufficient electro-catalytic activity limits the electrode performances and current efficiencies. In this work, catalytically active scandium is doped into LSTO to enhance the electro-cata…
The photochromic properties of diarylethenes, some of the most studied class of molecular switches, are known to be controlled by non-adiabatic decay at a conical intersection seam. Nevertheless, as their fatigue-reaction mechanism - leading to non-photochromic products - is yet to be understood, we investigate the ph…
This study describes the synthesis of zinc oxide nanoparticles (ZnO NPs) using a microfluidic system. A continuous and efficient synthetic process was developed based on a microfluidic reactor in which was implemented a time pulsed mixing method that had been optimized using numerical simulations and experimental meth…
A new strategy was developed to grow γ-Fe <sub>2</sub> O <sub>3</sub> nanosheet arrays on graphene sheets, showing excellent electromagnetic wave absorption properties with a lightweight characteristic.
A new MnO <sub>2</sub> @Co <sub>3</sub> O <sub>4</sub> hybrid with small-sized Co <sub>3</sub> O <sub>4</sub> nanoparticles grown on α-MnO <sub>2</sub> nanotubes exhibited much improved capacitive performances than those of pristine α-MnO <sub>2</sub> nanotubes and a physical mixture of α-MnO <sub>2</sub> nanotubes an…
A rare example of dual coordination modes by a novel tridentate ligand gives rise to unique fac-and mer-Ru((II/III)) complexes. The mer-Ru(II)-complex displays the farthest red-shift of a triplet metal-to-ligand charge transfer ((3)MLCT) emission with a tridentate ligand for a mononuclear complex. This observation is…
We investigate charge transport in a chemically reduced graphene oxide (RGO) film of sub-micron thickness. The I-V curve of RGO film shows current switching of the order of ∼10(5) above the threshold voltage. We found that the observed I-V curve is consistent with quantum tunnelling based charge transport. The quantum…
In electro-optic (EO) materials, realization of large EO coefficients for organic EO materials requires the simultaneous optimization of chromophore first hyperpolarizability, acentric order, molecular shape <italic>etc</italic> .
Hierarchical porous β-MnO2 nanoflowers self-assembled by ultrathin (thickness less than 10 nm) nanoplates have been successfully fabricated at room temperature. Because of its high specific surface area (267 m2 g−1) and proper pore size distributions (average pore size, ca. 5.9 nm), the obtained 3D nanomaterials achie…
Improving the tensile strength and modulus of aramid fibers by enhancement of the amorphous phase in supercritical carbon dioxide.
Flower‐like bundles of ZnO nanosheets have been prepared by using preheating hydrothermal process without any surfactants. The flower‐like bundles consist of many thin and uniform hexagonal‐structured ZnO nanosheets, with a thickness of 50 nm. The selected area electronic diffraction (SAED) and high‐resolution transmi…
A poly(ethylene glycol)-b-poly(γ-(2-methoxyethoxy)esteryl-L-glutamate) (PEG-b-poly-L-EG2Glu) diblock was prepared by the ring-opening polymerization (ROP) of L-EG2Glu N-carboxyanhydride (NCA) using PEG–NH2 as the macroinitiator. When the average degree of polymerization (DP) for poly-L-EG2Glu was below 40, the PEG-b-p…
A novel ferrocenyldithiophosphonate (TPFc) functionalized monomer and its conductive copolymer were synthesized, characterized and its potential use for biosensor applications was investigated.
The electrode material is a key component for supercapacitor cell performance. As it is known, performance comparison of commercial available batteries and supercapacitors reveals significantly lower energy storage capability for supercapacitor devices. The energy density of commercial supercapacitor cells is limited…
This chapter offers an overview of biopolymer-based lightweight materials with respect to their potential for packaging applications. Biopolymer-based materials have garnered increasing attention from packaging markets due to concerns in recent years from both environmental and economic perspectives of traditional pet…
The effects of precipitate distribution in commercial Mg alloys on the discharge behavior of a Mg–air battery were investigated. Rolled Mg–9 mass%Al–1 mass%Zn (AZ91) alloy sheets were selected as the anode. The discharge behaviors were evaluated by constant current discharge tests, and the corrosion behaviors were est…
Biosorption of arsenic (III) and (V) from aqueous solutions by living and dried biomass of fresh water microalgae was investigated. A total of five microalgae namely Chlorella, Oscillatioria, Scenedesmus, Spirogyra and Pandorina were identified as arsenic tolerant and used for further studies. Varying conditions of pH…
