The synthesis, optoelectronic properties and near-infrared electroluminescent heterojunctions of a twisted and soluble 7,8,15,16,23,24-hexaazatrianthrylene derivative are reported.
In recent years, biodegradable polymers derived from bioresources have received more and more attention.
Bubbles, droplets or particles in flowing complex media such as foams, emulsions or suspensions follow highly complex paths, with the relative motion of the constituents setting the energy dissipation rate. What is their dynamics, and how is this connected to the global rheology? To address these questions, we probe t…
Heat accumulation is a severe problem for high-power light-emitting diodes (LEDs). Here, we introduce a thermostable and transparent lateral heat spreader as an additional heat-escaping channel of an LED chip to improve the thermal management of LED devices. The lateral heat spreader was prepared based on a silver nan…
We have reported the use of carboxylate-alumoxanes as efficient nucleating agents for isotactic polypropylene (iPP) with a possible structural correlation to the nucleation efficiency. The unique, butterfly-like structure of carboxylate-alumoxanes correlates well with the nucleation characteristics of iPP and, for the…
The first two families of homodinuclear lanthanide(III) complexes, formulated as [(L(OEt))2Ln2(L1)] and [(LOEt)2Ln2(L2)] (Ln(3+) = Dy(3+), Tb(3+), Ho(3+), Gd(3+), and Y(3+); L1(4-) = 2,2',2'',2'''-[1,2,4,5-benzenetetrayltetrakis(nitrilomethylidyne)]tetrakisphenolate; L2(4-) = 2,2',2'',2'''-[[1,1'-biphenyl]-3,3',4,4'-t…
Novel cobalt sulfide hydrangea macrophylla with conductive carbon layer on the surface was synthesized in a one-pot method using 1-dodecanethiol as the sulfur source connected with long carbon chains as the electroactive material for supercapacitors.
Silicon nitride nanowires were synthesized using silicon monoxide as raw materials and an alumina plate as substrate at 1500°C. The obtained nanowires were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, high-resolution transmission electron microscopy and the…
We fabricate honeycomb-like poly acrylic acid (PAA) surfaces and achieve oil adhesion regulation underwater by changing the pore size and the solution pH, which affect triple-phase contact line (TCL) continuity and the negative pressure in the pores.
Manganese oxide-doped Al2O3 microspheres were synthesized via a redox method, and were then deposited with Au nanoparticles using a deposition-precipitation method. The obtained catalyst is not only highly active and selective for the preferential oxidation of CO in a H2-rich stream, but also shows excellent stability…
This study demonstrates the important effect of processing on the B-site ordering in Pb(Sc <sub>0.5</sub> Nb <sub>0.5</sub> )O <sub>3</sub> ceramics.
Schematic illustrations of the self-assembly of BGCs and photographs of superhydrophobic performance.
Temperature-dependent domain configurations were studied for both unpoled and poled [110] <sub>C</sub> -oriented 0.63Pb(Mg <sub>1/3</sub> Nb <sub>2/3</sub> )O <sub>3</sub> –0.37PbTiO <sub>3</sub> (PMN–0.37PT) single crystals by polarized light microscopy (PLM).
Asymmetric hybrid nanoparticles have many important applications in catalysis, nanomotion, sensing, and diagnosis, however ways to generate the asymmetric hybrid nanoparticles are quite limited and inefficient. Most current methods rely on interfacial adhesion and modification of already formed particles. In this arti…
Bioactivity and improved mechanical properties of hydroxyapatite/Mg–Al-layered double hydroxide nanocomposite are reported for the first time.
Herein, 1F2, an anti-HER2 monoclonal antibody (mAb), was covalently coupled to the surface of 5-Fluorouracil (5-FU) loaded bovine serum albumin (BSA) nanoparticles. Concerning two different crosslinkers for conjugation of 1F2, Maleimide-poly (ethylene glycol)-Succinimidyl carbonate (Mal-PEG5000-NHS) was selected due t…
A functionalized HA derivative (HA–EDA–C <sub>18</sub> ) was processed with silk fibroin <italic>via</italic> a salt leaching procedure to produce stable porous scaffolds for biomedical applications. The HA derivative was able to induce β-sheet transitions on fibroin.
Many substances can exist in different crystalline forms called polymorphs that have the same chemical formula but different properties such as solubility, density, melting point, stability or bioavailability. In order to guarantee the purity and quality of the final product it is very important to monitor and control…
Herein, hyperbranched poly(ethylene glycol)-based supramolecular nanoparticles with pH-sensitive properties were designed and used for targeted drug delivery. Via host-guest recognition between benzimidazole anchored poly(ethylene glycol)-hyperbranched polyglycerol (PEG-HPG-BM) and folic acid modified CD (FA-CD), targ…
In the search for new multifunctional spin crossover molecular materials, here we describe the synthesis, crystal structures and magnetic and photomagnetic properties of the complexes trans-[Fe(Fc-tzpy)2(NCX)2]·CHCl3 where Fc-tzpy is the ferrocene-appended ligand 4-(2-pyridyl)-1H-1,2,3-triazol-1-ylferrocene, X = S (1)…
