Linear 3d–4f compounds: synthesis, structure, and determination of the d–f magnetic interaction
A family of [RE2M2L2(BA)6] (RE = Gd, Tb, Dy, Y; M = Co, Ni, Cu, Zn; L = 1,2-bis(2-hydroxy-3-methoxybenzylidene)hydrazine; BA = benzoic acid) complexes were synthesized and structurally and magnetically characterized. The magnetic interactions between spin centers were systematically investigated. The interactions of M…
Superhydrophilic and underwater superoleophobic mesh coating for efficient oil–water separation
High efficiency of oil–water separation was easily achieved with reusable metal meshes coated by NiOOH nanoflake honeycomb network.
A silicon nanocrystal/polymer nanocomposite as a down-conversion layer in organic and hybrid solar cells
Silicon nanocrystal (Si-nc) down-conversion is demonstrated to enhance organic and hybrid organic/inorganic bulk heterojunction solar cells based on PTB7:[70]PCBM bulk heterojunction devices. Surfactant free surface-engineered Si-ncs can be integrated into the device architecture to be optically active and provide a m…
Structure and segregation of dopant–defect complexes at grain boundaries in nanocrystalline doped ceria
Grain boundaries (GBs) dictate vital properties of nanocrystalline doped ceria. Thus, to understand and predict its properties, knowledge of the interaction between dopant-defect complexes and GBs is crucial. Here, we report atomistic simulations, corroborated with first principles calculations, elucidating the fundam…
Determination of melamine and malachite green by surface-enhanced Raman scattering spectroscopy using starch-coated silver nanoparticles as substrates
Schematic illustration of the starch-coated AgNP SERS measurement for determining analytes.
A water-soluble tetraphenylethene based probe for luminescent carbon dioxide detection and its biological application
A water-soluble tetraphenylethene derivative (TPE-ONa) was developed for luminescent carbon dioxide detection in aqueous solution and porous film, which is able to monitor the variation of external CO <sub>2</sub> concentration of living cells.
Heteroaggregation of bare silver nanoparticles with clay minerals
In this study, we investigated the heteroaggregation of silver nanoparticles with clay minerals in neutral pH solutions as a function of electrolyte type and concentration.
Strain induced crystallization and melting of natural rubber during dynamic cycles
Strain-induced crystallization (SIC) of natural rubber (NR) is studied during dynamic cycles at high frequencies (with equivalent strain rates ranging from 7.2 s(-1) to 290 s(-1)). The testing parameters are varied: the frequency, the temperature and the stretching ratio domain. It is found that an increase of the fre…
Use of extension-deformation-based crystallisation of silk fibres to differentiate their functions in nature
β-Sheet crystals play an important role in determining the stiffness, strength, and optical properties of silk and in the exhibition of silk-type-specific functions. It is important to elucidate the structural changes that occur during the stretching of silk fibres to understand the functions of different types of fib…
A spiropyran-based X-ray sensitive fiber
This study attempted to visualize reversible X-ray radiation by using a poly-(l-lactic acid) (PLLA) composite fiber with an average diameter of 150 μm. The fiber contains photostimulable phosphor (PSP) BaFCl:Eu(2+) particles that are subsequently dyed with the photochromic spiropyran dye (1,3,3-trimethylindolino-6'-ni…

Phase transition characteristics and associated piezoelectricity of potassium-sodium niobate lead-free ceramics
To achieve high piezoelectric activity and a wide sintering temperature range, the ceramic system concerning (1 - x)(K(0.48)Na(0.52))(Nb(0.96)Sb(0.04))O(3)-x[Bi(0.5)(Na(0.7)Ag(0.3))(0.5)](0.90) Zn(0.10)ZrO(3) was designed, and the rhombohedral-tetragonal (R-T) phase boundary can drive a high d(33). Phase transition ch…
An organic anion template: a 24-nucleus silver cluster encapsulating a squarate dimer
The first silver cluster encapsulating an organic anion-squarate dianion-has been synthesized. Two C4O4(2-) anions arranged in a staggered sandwich type arrangement are confined in the Ag24 cage. The incorporation of squarate anions into the silver alkynyl system leads to the red shift of absorption of the cluster in…
MIL-100 derived nitrogen-embodied carbon shells embedded with iron nanoparticles
The use of metal-organic frameworks (MOFs) as templates and precursors to synthesize new carbon materials with controllable morphology and pre-selected heteroatom doping holds promise for applications as efficient non-precious metal catalysts. Here, we report a facile pyrolysis pathway to convert MIL-100 into nitrogen…
Er3+-doped fluorogallate glass for mid-infrared applications
We report an Er 3 -doped fluorogallate glass with good thermal and chemical stability. The low maximum phonon energy and high mid-infrared (IR) transmittance of the glass are confirmed by Raman and IR spectra, respectively. Based on Judd-Ofelt theory, intensity parameters and radiative properties are determined from t…

Thermal perturbation nucleation and growth of silver molybdate nanoclusters by a dynamic template route
Silver molybdate (Ag2MoO4) nanoclusters were first prepared by a dynamic template route under 20 °C. The heat released from the polymerization of the acrylamide (AM) assisted templates induced high active sites to be generated on the surface of the crystal where more attracted nuclei were adsorbed on. The continuously…
