Network representations are becoming increasingly popular for analyzing kinetic data from techniques like Milestoning, Markov State Models, and Transition Path Theory. Mapping continuous phase space trajectories into a relatively small number of discrete states helps in visualization of the data and in dissecting comp…
Decoupling conformational changes from aggregation will help us understand amyloids better. Here we attach Alzheimer's amyloid-β(1-40) monomers to silver nanoparticles, preventing their aggregation, and study their conformation under aggregation-favoring conditions using SERS. Surprisingly, the α-helical character of…
A facile generic solvothermal alcoholysis strategy is employed to prepare Mo-Sn oxide cage-bell hybrid nanoparticle aggregates. The intrinsic hollow core-shell nature as well as the multi-element characteristics of active components of the unique nanostructures contribute greatly to the enhanced performance as anode m…
Cu 2 ZnSnS 4 (CZTS) is a promising material for solar energy conversion, but synthesis of phase-pure, anisotropic CZTS nanocrystals remains a challenge. We demonstrate that the initial concentration (loading) of cationic precursors has a dramatic effect on the morphology (aspect ratio) and composition (internal archit…
The effects of Al2O3 modification of the beta-SiC support on Fischer–Tropsch synthesis (FTS) catalysts were investigated in terms of the dispersion of cobalt particles through different metal support interactions for higher CO conversion and stability. The SiC support was previously modified using a alumina precursor…
Biopolymer-based nanogels (bionanogels) are a promising platform as polymer-based drug delivery systems encapsulting hydrophilic anticancer therapeutics; however, enhanced/controlled drug release is highly desired. Herein, we report new dual stimuli-responsive bionanogels (ssBNGs) as potential intracellular delivery n…
We study the motion of a colloidal particle as it is driven by an oscillating external force of arbitrary amplitude and frequency through a colloidal dispersion. Large amplitude oscillatory flows (LAOFs) are examined predominantly from a phenomenological perspective in which experimental measurements inform constituti…
Terahertz (THz) transmission modulation through copper phthalocyanine (CuPc)-coated Si under various laser light irradiation conditions was investigated using THz time-domain spectroscopy. The charge carrier transfer from Si to CuPc is crucial for photo-induced metallization, and the thickness of the CuPc layer is a c…
Interlayer-expanded zeolite, IEZ-NSI, has been post-synthesized from a two-dimensional (2D) layered precursor Nu-6(1) (Si/Al ratio = 30 – ∞) by intercalating with diethoxydimethylsilane in hydrochloric acid solution. Ethanol was demonstrated to be a suitable solvent for inducing an effective interlayer pillaring with…
A hierarchical macroporous Zn2SnO4-ZnO nanorod composite film is prepared through a drop-casting process of PS@Zn2SnO4 and subsequent hydrothermal growth of ZnO nanorod. CdS/CdSe co-sensitized solar cells based on the macroporous Zn2SnO4-ZnO nanorod composite photoelectrode exhibits an enhancement of 34.4% in power co…
A novel porous carbon nanosheet was successfully fabricated by a one-step annealing process with folic acid as the carbon source in the absence of any other reagents or templates. The product exhibited a large specific surface area and good porosity. Meanwhile, the carbon nanosheets as a metal-free catalyst showed a h…
The precursor hydrozincite was synthesized through hydrothermal reaction and hierarchically assembled 3D porous ZnO was prepared by calcination of the precursor at 400 °C for 15 min. The 3D porous ZnO was composed of micrometer spheres which were assembled from nanoflakes. The sensor based on 3D porous ZnO showed impr…
A new efficient approach for the in situ synthesis of anchored ruthenium nanoparticles (RuNP) in three different kinds of mesoporous silica materials, MCM-41, SBA-15 and HMS, has been developed. Solids have been synthesized under very mild conditions from RuCl3·H2O salt reduced in one hour at room temperature in the m…
We investigate from a practitioner's point of view the computation of the ionization potential (IP) within density-functional theory (DFT). DFT with (semi)local energy-density functionals is plagued by a self-interaction error which hampers the computation of the IP from the single-particle energy of the highest occup…
An ultrafast fractional magneto-thermoelasticity model utilizing the modified hyperbolic heat conduction model with fractional order is formulated to describe the thermoelastic behavior of a thin perfect conducting metal film irradiated by a femtosecond laser pulse. Some theorems of generalized thermoelasticity follow…
A novel benzoxazine (BOZ)/epoxy resin (ER) blend with multiphase structure was successfully prepared under the catalysis of imidazole (MZ) via reaction-induced phase separation. The toughness and thermal properties of the novel blend were greatly improved compared with the homogeneous PBOZ and PBOZ/ER systems.
Gold nanoparticles are efficiently labelled with a luminescent ruthenium complex, producing 13 and 100 nm diameter, monodisperse red-emissive imaging probes with luminescence lifetimes prolonged over the molecular unit. Single, 100 nm particles are observed in whole cell luminescence imaging which reveals their biomol…
Carbon quantum dots (CQDs) and two dimensional (2D) graphene sheets were prepared from formic acid by microwave mediated thermal method. Microwave irradiation followed by thermal evaporation of formic acid produces fluorescent CQDs. The fluorescence emission of CQDs in water can be tuned between 310 and 820 nm by chan…
The development of accurate implicit solvation models with low computational cost is essential for addressing many large-scale biophysical problems. Here, we present an efficient solvation term based on a Gaussian solvent-exclusion model (EEF1) for simulations of proteins in aqueous environment, with the primary aim o…
Natural biological functional scaffolds, consisting of biological materials filled with promoting elements, provide a promising strategy for the regeneration of peripheral nerve defects. Collagen conduits have been used widely due to their excellent biological properties. Linear ordered collagen scaffold (LOCS) fibers…
