In the present work, the g-C 3 N 4 /nanocage ZnS composite photocatalyst was fabricated and the photocatalytic activity was enhanced under visible-light irradiation.
Hydrogels are hydrophilic polymer networks that are capable of imbibing large amounts of water. In this work, hydrogels prepared from natural and synthetic polymers were irradiated by using electron beam irradiation. The morphology of hydrogel inter-polymeric network (IPN) was investigated using Scanning Electron Micr…
The Kohn--Sham model is a powerful, widely used approach for computation of ground state electronic energies and densities in chemistry, materials science, biology, and nanoscience. In this paper, we study adaptive finite element approximations for the Kohn--Sham model. Based on the residual-type a posteriori error es…
We propose a temperature dependent reaction scheme between trimethylaluminum and poly(methyl methacrylate) for enhanced control of vapor phase polymer modification.
We report on a novel type of shaped hydrogel microparticles which undergo large, rapid, and reversible volume changes in response to solution pH. The cubic hydrogels are produced as interconnected poly(methacrylic acid) (PMAA) network replicas of mesoporous manganese oxide templates by sequential infiltration of (PMAA…
Layer-controlled MoS 2 nanosheets, directly prepared through a facile and scalable chemical method, exhibit a significant layer number effect on the hydrogen evolution reaction (HER).
A family of cobalt complexes supported by a tridentate Schiff base ligand with a labile donor (O, S, N) as a pendant arm (Co1-Co12, formulated as CoL2) were synthesized by the treatment of the corresponding ligands with cobalt acetate tetrahydrate. The resultant complexes were well characterized by elemental analysis,…
Lithium ion batteries exhibit the highest energy densities of all battery types and are therefore an important technology for energy storage in every day life. Today's commercially available batteries employ organic polymer lithium conducting electrolytes, leading to multiple challenges and safety issues such as poor…
High efficiency blue (F), green (P), orange (P) and F–P hybrid warm white single-layer OLEDs are fabricated through a simple manufacturing process.
The hysteresis and dynamics of the phase transition of the perovskite salt [Pb(II)I4(2-),(C12H25NH3(+))2] is shown to be significantly modified when strongly coupled to the vacuum field inside a micro-cavity. The transition barrier is increased and the hysteresis loop is enlarged, demonstrating the potential of contro…
Fibrin nanoparticles were incorporated into a chitosan–gelatin hydrogel matrix to develop a composite bandage with wound-healing potential.
The study of drug release dynamic is aiming at understanding the process that drugs release in human body and its dynamic characteristics. It is of great significance since these characteristics are closely related to the dose, dosage form, and effect of the drugs. The Noyes-Whitney function is used to represent how t…
Oligo(carbonate-ether) triol with controllable M n and CU was synthesized by using TMA as a novel chain initiation-transfer agent catalyzed by Zn-Co-DMC.
Thin lubrication flows accompanying drainage from curved surfaces surround us (e.g., the drainage of the tear film on our eyes). These draining aqueous layers are normally covered with surface-active molecules that render the free surface viscoelastic. The non-Newtonian character of these surfaces fundamentally alters…
Natural graphite was oxidized via the Hummer's method and sonicated to obtain graphene oxide (GO). A three-step modification process was performed to attach a reversible addition–fragmentation chain transfer (RAFT)-agent onto the GO surface and obtain GO-RAFT nanosheets. RAFT polymerization of 2-hydroxyethyl methacryl…
Highly ordered N-doped mesoporous niobium oxide (NMNb) was prepared via a facile solid state reaction method using urea as a nitrogen source. The mesoporous structure of niobium oxide (MNb) is beneficial to the N dopant that is effectively incorporated into the lattice of MNb, resulting in a significantly enhanced vis…
DBU-based ionic liquids with benzenesulfonate anion were excellent solvents for dehydration of glucose to HMF with high yield of 83.4%.
Organo-mineral interactions are important for the cycling and preservation of organic carbon (OC) in soils. To understand the role of soil mineral surfaces in organo-mineral interactions, we used a sequential density fractionation procedure to isolate 2.6 g cm-3 density fractions from topsoils (0-10 cm) of contrasting…
Comparative photocatalysis degradation of MB dye under ultraviolet light irradiation: (a) without photocatalyst; (b) commercial P25 TiO 2 powder; and (c) TiO 2 nanoparticles.
A series of ionic liquids (ILs) were investigated for removal and storage of radioactive iodine (I2) waste released by nuclear power plants. The I2 removal efficiency of ILs was dependent upon the anion species while cation species seemed to have little influence. Particularly, the I2 removal efficiency of [Bmim][Br]…
