Plasma activated water (PAW) has emerged as a viable technique for sterilization process since it contains some long-lived reactive oxygen and nitrogen species along with very short-lived but strong oxidation agents such hydroxyl radical (OH*) superoxide anion (O2 −). However, the concentrations of nitrite, nitrate, ozone are often insufficient in sterilization, or only small amount PAW can be generated. In this study, we developed state-of-the-art approach by combining microbubbles (MBs)...

The performance of an Er/sup 3+/-doped fiber amplifier pumped by 0.98 mu m InGaAs laser diodes (LDs) is reported.

The 11 April 2011 Hamadoori, Fukushima prefecture, northeast Japan, earthquake occurred in a seismically active area, one month after the March Off Pacific Coast of Tohoku earthquake. Hamadoori resulted 14‐km‐long down‐to‐the‐west normal‐slip rupture on north‐northwest–south‐southeast‐striking Itozawa fault, as well 16‐km‐long down‐to‐the‐south west‐northwest–east‐southeast‐striking Yunodake fault. slip along fault increases abruptly from southern end to central part where measured maximum...

High-power GalnAs strained quantum well lasers with an emission wavelength of 0.98μ, suitable for Er3+-doped fibre amplifier pumping, have been fabricated.

The logistic map is a chaotic mapping. Although several studies have examined maps over real domains with infinite/finite precisions, there has been little analysis of the integers. Focusing on differences between domain infinite precision and integers finite precision, we herein show characteristic properties discuss sequences generated by map.

This paper proposes a new multi-value sequence generated by utilizing primitive element, trace, and power residue symbol over odd characteristic finite field. In detail, let p k be an prime number as the factor of p-1, respectively. Our proposal generates k-value T={ti | ti=fk(Tr(ωi)+A)}, where ω is element in extension field $\F{p}{m}$, Tr(⋅) trace function that maps $\F{p}{m} \rightarrow \f{p}$, A non-zero scalar $\f{p}$, fk(⋅) certain mapping based on k-th symbol.

Flow dynamics in nano-scaled structures such as nanochannels and nanopores have recently become important developing next-generation high-speed DNA sequencers. In the present paper, we report electrokinetic flow of λDNA confined having heights that are smaller than molecular radius gyration.

We present experimental observations of microjets formed by cavitation microbubbles. An underwater electric discharge, applied beneath a flat free surface, produces primary compression wave, which undergoes several phase inversions upon reflections from the surface and spark-bubble interface. The first reflection yields tension cloud secondary bubbles in liquid, some form collapse. tuning these enables an effective control microjet direction bubble cloud. All jets microbubbles between spark...

Abstract Small C3-symmetric supramolecules, 1:3 complexes of tri(2-aminoethyl)amine (1) and 3,4,5-trialkoxybenzoic acid (2c–2n, R = (CH2)n−1CH3, n 5–16) generated a stable hexagonal columnar phase. The phase behaviors, stoichiometry, supramolecular structure, superstructure were investigated.

Total internal reflection fluorescence (TIRF) microscopy enables the single-molecule observation in liquid near substrate surface. However, evaluation of diffusion from their individually-tracked positions entails difficulty treatment molecular adsorption on substrate. We propose a novel technique to evaluate them, and two types near-surface Brownian motion were determined for DNA. One is glass surface, other adsorption-dominated motion, which also found be diffusive rather than anchored Our...
