Multifunctional foams derived from poly(melamine formaldehyde) as recyclable oil absorbents
Ultralight, fire-resistant, and compressible foams as recyclable oil absorbents are facilely prepared from cheap melamine resins.
Multiple interfaces in self-assembled breath figures
This feature article describes the multiple interfaces in the breath figure (BF) method toward functional honeycomb films with ordered pores. If a drop of polymer solution in a volatile solvent such as carbon disulphide is placed in a humid environment, evaporative cooling leads to self-assembled arrays of condensed w…
Inhibitory effect of NO2 on the selective catalytic reduction of NOx with NH3 over one-pot-synthesized Cu–SSZ-13 catalyst
The selective catalytic reduction of NOx with NH3 (NH3–SCR) on a Cu–SSZ-13 catalyst prepared by a one-pot-synthesis method was inhibited by NO2 in the low temperature range. NH4NO3 that accumulated on the catalyst surface was the reason for this phenomenon. The key step of the NH3–SCR reaction over the catalyst at low…
Surface chemistry, charge and ligand type impact the toxicity of gold nanoparticles to Daphnia magna
Using highly characterized gold nanoparticles this study determined that ligand identity, nanoparticle surface charge and aggregation type alters toxicity of gold nanoparticles to Daphnia magna .
Oxide enthalpy of formation and band gap energy as accurate descriptors of oxygen vacancy formation energetics
Despite the fundamental role oxygen vacancy formation energies play in a broad range of important energy applications, their relationships with the intrinsic bulk properties of solid oxides remain elusive. Our study of oxygen vacancy formation in La1−xSrxBO3 perovskites (BCr, Mn, Fe, Co, and Ni) conducted using modern…
The highly enhanced performance of lamellar WS2 nanosheet electrodes upon intercalation of single-walled carbon nanotubes for supercapacitors and lithium ions batteries
Hybrid lamellar porous electrodes with excellent electrochemical performance were successfully fabricated by homogeneously intercalating single-walled carbon nanotubes into the lamellar assembled WS2 nanosheets through vacuum filtration.
Pure white-light and yellow-to-blue emission tuning in single crystals of Dy( iii ) metal–organic frameworks
Direct white-light emission was first achieved in a single phase material of a Dy(III) metal-organic framework, which also shows tunable yellow-to-blue photoluminescence upon variation of excitation wavelengths.
Electrochemically induced Fenton reaction of few-layer MoS 2 nanosheets: preparation of luminescent quantum dots via a transition of nanoporous morphology
Electrochemically induced Fenton (electro-Fenton) reaction was used for efficient and controllable preparation of hydroxyl radicals, leading to the generation of luminescent quantum dots through etching of as-exfoliated MoS2 nanosheets. Morphologic changes of MoS2 nanosheets during the electro-Fenton reaction were mon…
Solution processed polydimethylsiloxane/gold nanostar flexible substrates for plasmonic sensing
Gold nanostars can display tunable optical properties in the visible and near IR, which lead to strong electromagnetic field enhancement at their tips. We report generalized application of gold nanostars for ultrasensitive identification of molecules, based on both localized surface plasmon resonance (LSPR) and surfac…

Synthesis of Nickel and Nickel Hydroxide Nanopowders by Simplified Chemical Reduction
Nickel nanopowders were synthesized by a chemical reduction of nickel ions with hydrazine hydrate at pH ~12.5. Sonication of the solutions created a temperature of 54–65°C to activate the reduction reaction of nickel nanoparticles. The solution pH affected the composition of the resulting nanoparticles. Nickel hydroxi…

We report a novel method for synthesizing water-dispersible silicon nanoparticles (Si NPs) with a simple one-step procedure using mild reagents (3-aminopropyl) trimethoxysilane (APTES) and ascorbate sodium (AS). This is the first report of "green" synthesis of Si NPs on a large scale and at low cost. The method involv…
