An Au-SiO2-Au (metal-insulator-metal; MIM) surface-plasmon-polariton (SPP) guide is schematically presented in Fig. S1a. As the name “MIM” implies, a structural symmetry exists with respect to the mirror plane that cuts through the center of the SiO2 layer and is parallel to the x–y plane. As a result, supported SPP modes in the guide can be classified into two major types, each with its own di...

Despite decades of studies of calcium-silicate-hydrate (C-S-H), the structurally complex binder phase of concrete, the interplay between chemical composition and density remains essentially unexplored. Together these characteristics of C-S-H define and modulate the physical and mechanical properties of this "liquid stone" gel phase. With the recent determination of the calcium/silicon (C/S = 1....

BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is currently the eighth leading cause of cancer death worldwide. The often severe side effects, functional impairments and unfavorable cosmetic outcome of conventional therapies for HNSCC have prompted the quest for novel treatment strategies, including the evaluation of nanotechnology to improve e.g. drug delivery and cancer imaging. Alt...

The effect of 2CaO·SiO2 (C2S) addition on the melt formation temperatures and microstructures iron ore sinters has been elucidated from perspective silico-ferrite calcium aluminum (SFCA) in bonding phases as SFCA improve strength sinter. samples used this study are categorized into two: “C + S” “C2S”. contain CaO SiO2 components, while “C2S” intermediate compounds SiO2, i.e., C2S. Both have an ...

A new simple and cheap method to grow large scale SiC-SiO2 nanocables on catalyzed Si substrate directly is presented. The method is based on the thermal decomposition of methanol. The grown nanocables consisted of crystalline 3C-SiC and amorphous SiO2. A simple etching and oxidation process was used to analyze the contribution of SiC and SiO2 components to photoluminescence.

Covalent labeling of solvent exposed amino acid residues using chemical reagents/crosslinkers followed by mass spectrometric analysis can be used to determine the solvent accessible amino acids of a protein. A variety of chemical reagents containing cleavable bonds were developed to label abundantly found lysine residues on the surface of protein. To achieve efficient separation of labeled pept...

and Introduction: There are currently no electrically-pumped semiconductor lasers that can operate in the 1-5 terahertz (THz) spectral range at room temperature. An alternative method of producing room temperature THz light is based on intra-cavity difference frequency generation (DFG) in dual wavelength mid-infrared quantum cascade lasers. Our THz DFG sources can provide tunable output of over...

Humans may be exposed to engineered silica nanoparticles (SiO2-NPs) but potential adverse effects are poorly understood, in particular in relation to cellular effects and modes of action. Here we studied effects of SiO2-NPs on cellular function in human hepatoma cells (Huh7). Exposure for 24 h to 10 and 50 μg/ml SiO2-NPs led to induction of endoplasmic reticulum (ER) stress as demonstrated by t...

the aims of the study were to investigate the effect of poly(ε -caprolactone) (pcl) and nano- sio2 within the thermoplastic starch (tps) blends on the rate and extent of starch enzymatic hydrolysis using enzymes α-amylase and amyloglucosidase. the results of this study have revealed that blends with nano-sio2 content at 6 wt% exhibited a significantly reduced rate and extent of starch hydrolysi...

We have studied the electron transport in SiO2(Co)/GaAs and SiO2(Co)/Si heterostructures, where the SiO2(Co) structure is the granular SiO2 film with Co nanoparticles. In SiO2(Co)/GaAs heterostructures giant magnetoresistance effect is observed. The effect has positive values, is expressed, when electrons are injected from the granular film into the GaAs semiconductor, and has the temperature-p...
