This work aims at establishing a link between process conditions and resulting micromechanical properties for aminoplast core/shell microcapsules. The investigated capsules were produced by the in situ polymerization of melamine formaldehyde resins, which represents a widely used and industrially relevant approach in…
Near-infrared quantum cutting is widely studied for its potential application in photovoltaic solar cells. By using a fluorometer equipped with an integrating sphere, we measured the external quantum yield of near-infrared quantum cutting in Er 3+ /Yb 3+ doped La 2 O 2 S. It is found that by optimizing the synthesis p…
We have investigated the magnetoelectric properties originating from the spin-dependent hybridization between transition metal ($X$) $d$ orbital and ligand ion $p$ orbitals in the noncentrosymmetric crystals Ba${}_{2}X$Ge${}_{2}$O${}_{7}$ ($X=\text{Mn}$, Co, Cu). The novel magnetic-field responses of the electric pola…
Understanding the formation process in the controlled synthesis of nanocrystals will lead to the effective manipulation of the morphologies and properties of nanomaterials. Here, in-situ UV-vis and X-ray absorption spectroscopies are combined to monitor the tracks of the nucleation pathways in the solution synthesis o…
We report the experimental results of structural and sodium ionic conductive properties of the Na(BH4)–Na(NH2)–NaI system. Na(BH4)0.5(NH2)0.5 with [BH4]− and [NH2]− complex anions formed by combining Na(BH4) and Na(NH2) complex hydrides shows the most superior sodium ionic conductivity of 2 × 10−6 S/cm at 300 K becaus…
Harnessing the many favorable properties of ionic liquids in a solid electrolyte thin film form is desirable for a host of electrical energy storage applications, including electrochemical double layer capacitors. Using a cross-linked polymer matrix to provide structural support, freestanding ionogel materials can be…
A water-soluble derivative of N-confused porphyrin (NCP) was synthesized, and the photodynamic therapeutic (PDT) application was investigated by photophysical and in vitro studies. High singlet oxygen quantum yield in water at longer wavelength and promising IC(50) values in a panel of cancer cell lines ensure the pot…
We investigated the correlation between magnetization and oxygen vacancies in Zn0.95Co0.05O nanoparticles. Enhanced magnetizations were found in SiO2 nanopowders and carbon nanotubes (CNTS) treated Zn0.95Co0.05O, which are attributed to minimizing nanoparticle size and increasing oxygen vacancy concentration. After ox…
Density functional theory (DFT) calculations were performed in order to investigate the stability and the electronic structure of graphene-gold interfaces. Two configurations were studied: a gold cluster interacting with graphene and different polycyclic aromatic hydrocarbon (PAH) molecules, namely, C${}_{6}$H${}_{6}$…
Porous silicon (PSi) is a promising material in several biomedical applications because of its biocompatibility and biodegradability. Despite the plethora of studies focusing on the interaction of cells with micrometer and submicro geometrical features, limited information is available on the response of cells to subs…
Abstract This paper reports β ‐lactoglobulin amyloid protein fibrils directed synthesis of Titanium Dioxide (TiO 2 ) hybrid nanowires. Protein fibrils act as templates to generate closely packed TiO 2 nanoparticles on the surface of the fibrils using titanium (IV) bis (ammonium lactato) dihydroxide (TiBALDH) as precur…
Information on how cells interface with nanomaterials in biological environments has important implications for the practice of nanomedicine and safety consideration of nanomaterials. However, our current understanding of nanobiological interactions is still very limited. Here, we report the direct observation of nano…
Silicon-based active and reproducible surface-enhanced Raman scattering (SERS) substrate, i.e., silver nanoparticles decorated-silicon wafers (AgNPs@Si), is employed for constructing high-performance sensors. Significantly, the AgNPs@Si, facilely prepared via in situ AgNPs growth on silicon wafers, features excellent…
This chapter provides experimentalists a basic outline for analyzing/modeling thermoelectric transport at high temperatures. The single parabolic band (SPB) model is a powerful analytical tool when investigating thermoelectric transport. The SPB model is something of a diagnostic tool for both overall thermoelectric e…
Graphene has raised high expectations as a low-loss plasmonic material in which the plasmon properties can be controlled via electrostatic doping. Here, we analyze realistic configurations, which produce inhomogeneous doping, in contrast to what has been so far assumed in the study of plasmons in nanostructured graphe…
We first demonstrate how two-dimensional sheets are incorporated in the formalism for planar structures. Then we derive the interaction in the geometry of two freestanding graphene sheets and of one graphene sheet above a substrate. Numerical results are produced for the fully retarded interaction at 0 K and at room t…
Several drug delivery systems have been proposed to overcome physiological barriers, improving ocular bioavailability. Systemic routes are seldom used due to the blood-ocular barrier. Novel drug delivery systems based on nanotechnology techniques have been developed to overcome ocular physiological barriers. This non-…
Here we show that the 2.80(8)${\ensuremath{\mu}}_{\mathrm{B}}$ Fe${}^{\ensuremath{-}1}$ block antiferromagnetic order of BaFe${}_{2}$Se${}_{3}$ transforms into stripe antiferromagnetic order in KFe${}_{2}$Se${}_{3}$ with a decrease in moment to 2.1(1)${\ensuremath{\mu}}_{\mathrm{B}}$ Fe${}^{\ensuremath{-}1}$. This red…
We propose a new substitutional impurity complex in diamond composed of a lithium atom that is tetrahedrally coordinated by four nitrogen atoms (LiN_4). Density functional calculations are consistent with the hydrogenic impurity model, both supporting the prediction that this complex is a shallow donor with an activat…
We present evidence of type-I superconductivity in single crystals of ScGa${}_{3}$ and LuGa${}_{3}$, from magnetization, specific heat, and resistivity measurements: low critical temperatures ${T}_{c}=2.1$--2.2 K; field-induced second- to first-order phase transition in the specific heat, critical fields less than 240…
