Mechanics of advanced fiber reinforced lattice composites

Abstract: Fiber reinforced lattice composites are light-weight attractive due to their high specific strength and specific stiffness. In the past 10 years, researchers developed three-dimensional (3D) lattice trusses and two-dimensional (2D) lattice grids by various methods including interlacing, weaving, interlocking, filament winding and molding hot-press. The lattice composites have been applied in the fields of radar cross-section reduction, explosive absorption and heat-resistance. In this paper, topologies of the lattice composites, their manufacturing routes, as well as their mechanical and multifunctional applications, were surveyed.

Recent Advances in Carbon Nitride-based Nanomaterials for the Removal of Heavy Metal Ions from Aqueous Solution

Abstract: Graphitic-like carbon nitride (g-C3N4), one of the most significant two-dimensional layered materials, has attracted worldwide attention in multidisciplinary areas such as photocatalysis, energy conversion and environmental pollution management. Its derivative compounds have also attracted multifarious attention owing to the intrinsic characters of their stable physicochemical properties, low cost and environmentally friendly features. This review focus on the design of high-performance g-C3N4-based nanomaterials and their potential for pollutant elimination in environmental pollution cleanup. Over the past few years, significant advances have been achieved to synthesize g-C3N4 and g-C3N4-based nanomaterials, and their properties have been enhanced and characterized in detail. In this review, recent developments in the synthesis and modification of g-C3N4-based nanomaterials are summarized. The applications in heavy metal ions adsorption from wastewaters are gathered and their underlying reaction mechanisms are discussed. Finally, a summary and outlook are also briefly illustrated.

Molybdenum oxide nanosheets meet ascorbic acid: Tunable surface plasmon resonance and visual colorimetric detection at room temperature

Abstract: Here we report a simple, rapid, and environmentally friendly method for the preparation of non-stoichiometric MoO 3 (MoO 3-x ) nanosheets using ascorbic acid (AA) as a reducing agent under an acidic environment at room temperature. The resultant MoO 3-x nanosheets show an intense blue color and strong localized surface plasmon resonance (LSPR) in the visible and near-infrared region, which can be tuned by changing the pH values of the preparation solution. The hydrogen ions intercalate into the lattice of MoO 3 and bond to oxygen atoms to generate water molecules, and the electron of the AA is transferred to Mo cations, which results in the reduction of Mo 6+ and formation of oxygen vacancies, giving rise to the LSPR. Additionally, a visual colorimetric assay has been developed for the detection of AA in aqueous solutions and serum samples. The absorbance at 820 nm is linearly related to the logarithm of the AA concentration in the range of 1 mM–100 mM with a limit of detection of 0.09 mM at a signal-to-noise ratio of 3.
