The transition to simple liquid behaviour is studied in a set of modified hybrid water models where the potential energy contribution of the Lennard-Jones dispersion-repulsion contribution is progressively enhanced relative to the electrostatic contribution. Characteristics of simple liquid behaviour that indicate the…
We have previously explored cylindrical packings of disks and their relation to sphere packings. Here we extend the analytical treatment of disk packings, analyzing the rules for phyllotactic indices of related structures and the variation of the density for line-slip structures, close to the symmetric ones. We show t…
Sisal-like architectures of cobalt hydroxide carbonate precursors were prepared using Co(NO 3 ) 2 ·6H 2 O and CO(NH 2 ) 2 as raw meterials via a hydrothermal process, and the precursor could be transformed to Co 3 O 4 nanoparticles by calcination, while maintaining the original morphology. The as-prepared sample was c…
ABSTRACT 2‐((2,3‐Dihydrothieno[3,4‐ b ]dioxin‐2‐yl)methoxy)methyl oxirane (EDOT‐MO) was successfully synthesized by the reaction of epichlorohydrin with hydroxymethylated‐3,4‐ethylenedioxylthiophene (EDOT‐MeOH), which was synthesized via a simple four‐step sequence. Poly(hydroxymethylated‐3,4‐ethylenedioxylthiophene)…
In this work, density functional theory (DFT) calculations have been used to investigate chemical sensing on surfaces of single-layer MoS2 and graphene, considering the adsorption of the chemical compounds triethylamine, acetone, tetrahydrofuran, methanol, 2,4,6-trinitrotoluene, o-nitrotoluene, o-dichlorobenzene, and…
The preparation of a novel class of ε-caprolactone (CL) monomers, modified at the β-position of the ester function, is described. The efficient thia-Michael addition to cyclohex-2-en-1-one and subsequent Baeyer–Villiger oxidation provided the regioselectively modified CL monomers. To enable a sustainable Baeyer–Villig…
In this paper, a paper-based ultracapacitors were fabricated by the rod-rolling method with the ink of carbon nanomaterials, which were synthesized by arc discharge under various magnetic conditions. Composites of carbon nanostructures, including high-purity single-walled carbon nanotubes (SWCNTs) and graphene flakes…
Silicon quantum dots (QDs) embedded in hydrogenated amorphous Si-rich silicon carbide (α-SiC:H) thin films were realized by plasma-enhanced chemical vapor deposition process and post-annealing. Fluorescence spectroscopy was used to characterize the room-temperature photoluminescence properties. X-ray photoelectron spe…
Physicochemical properties of transition metal oxides are directly determined by the oxidation state of the metallic cations. To address the increasing need to accurately evaluate the oxidation states of transition metal oxide systems at the nanoscale, here we present "Oxide Wizard." This script for Digital Micrograph…
This paper is a review of earlier results which have been completed with recent investigations on the nature and sequence of phase transitions evolving in the antiferroelectric PbZr1–xSnxO3 single crystals (0 < x < 0.35). It was found that these crystals undergo several first-order phase transitions. To investigate th…
In order to reduce the effects of hydrolytic degradation and to maintain sufficient viscosity during processing of biomass based poly(l-lactic acid) (PLLA), various epoxy functional reactive oligomers have been characterized and incorporated into the degraded fragments as chain extenders. The molecular weight of PLLA…
A novel eco-friendly effort has been made for the synthesis of cadmium sulfide (CdS) nanoparticles using bacterial biomass. Although some articles have been reported on CdS nanoparticles synthesis by bacteria, here we have synthesized CdS nanoparticles using non-pathogenic bacteria Bacillus licheniformis MTCC 9555. UV…
The potential immune effects of titanium dioxide nanoparticles (nano-TiO₂) are raising concern. Our previous study verified that nano-TiO₂ induce local immune response in lung tissue followed by intratracheal instillation administration. In this study, we aim to evaluate the systemic immune effects of nano-TiO₂. Sprag…
This paper reports the findings of our efforts toward gaining a more complete understanding and utilization of galvanic replacement reactions involving manganese oxide with noble metals. It was revealed that the site of metal deposition is significantly affected by the variable oxidation state of manganese oxide. The…
Multiwalled carbon nanotubes (MWNTs) are utilized in a number of sectors as a result of their favorable electronic properties. In addition, MWNT antimicrobial properties can be exploited or considered a potential liability depending on their intended application and handling. The ability to tailor electrochemical and…

We successfully realized in‐situ monitoring plasmon‐driven selective reduction of 2,4‐dinitrobenzenethiol to 2,2′‐diamino‐dimercaptoazobenzene, revealed by high vacuum tip‐enhanced Raman spectroscopy (HV‐TERS). The HV‐TER spectra revealed that the 2‐nitro and the 4‐nitro of 2,4‐DNBT were selectively reduced to the 2‐a…
Surface exchange and oxygen vacancy diffusion dynamics were studied in double-perovskites LnBaCo2O5.5+δ (LnBCO) single-crystalline thin films (Ln = Er, Pr; -0.5 < δ < 0.5) by carefully monitoring the resistance changes under a switching flow of oxidizing gas (O2) and reducing gas (H2) in the temperature range of 250 ~…
Pure samples of a series of yttrium selenites, AY(SeO3)2 (A = Na, K, Rb, and Cs), were prepared through hydrothermal reactions using A2CO3, Y(NO3)3·6H2O, and SeO2. All four materials have 3D framework structures; however, they exhibit different channel geometries. The three-dimensional framework of NaY(SeO3)2 consists…
We demonstrate the surface-plasmon-induced enhancement of Förster resonance energy transfer (FRET)using a model multilayer core-shell nanostructure consisting of an Au core and surrounding FRET pairs, i.e., CdSe quantum dot donors and S101 dye acceptors. The multilayer configuration was demonstrated to exhibit synergi…
