Objective: The present study was aimed to develop and evaluate quantum dots (QDs) as a carrier for delivery of 5-fluorouracil (5-FU). Methods: This research work includes a synthesis, characterization and in vitro study of 5-fluorouracil (5-FU) QDs. Zinc oxide QDs were synthesized, and the drug was loaded on them. The…
The effect of dissolved poly(lactic acid) (PLA) on the solubility of gases (CO 2, N 2, and He) in dichloromethane (CH 2 Cl 2 ) was investigated, between 288 and 303 K, by measuring the equilibrium pressure in a closed vessel containing a gas and CH 2 Cl 2 solutions of different types (molecular weights) and concentrat…
Abstract This paper describes the synthesis and electrochemical properties of mesoporous titanium oxysulfides prepared through the chemical treatment of pristine mesoporous titanium oxide under various synthesis conditions. The materials were doped with sulfur by using hexamethyldisilathiane (HMDST), a strategy that w…
We propose a method and optical design for direct visualization of label-free detection. The system, similar to a tiny spectral analyzer, is composed of a nanostructure-based surface plasmon resonance chip, linear polarizer and 532 nm laser light source. The full-width-at-half-maximum bandwidths of the enhanced surfac…
We report the first example of an ionic graphene salt containing boron. An anionic charge is introduced to the graphene surface by means of 7,8-nido-[C2B9H11](-) carborane clusters covalently and electronically bound to the graphene lattice, and this new material was isolated as its Cs(+) salt.
Infrared spectra of Ne-C2D2 are observed in the region of the ν3 fundamental band (asymmetric C-D stretch, ≈2440 cm(-1)) using a tunable optical parametric oscillator to probe a pulsed supersonic slit jet expansion from a cooled nozzle. Like helium-acetylene, this system lies close to the free rotor limit, making anal…
Probe-based data storage attracted many researchers from academia and industry, resulting in unprecendeted high data-density demonstrations. This topical review gives a comprehensive overview of the main contributions that led to the major accomplishments in probe-based data storage. The most investigated technologies…
Connections between metals and heterogeneous solid state materials form buried interfaces. These ubiquitous structures play an essential role in determining the performances of many nano- and microdevices. However, the information about the chemistry, structure, and properties of these real interfaces is intrinsically…
Among candidates for chemical hydrogen storage in proton exchange membrane (PEM) fuel cell automotive applications, ammonia borane (AB, NH 3 BH 3 ) is considered to be one of the most promising materials due to its high hydrogen content of 14–16 wt % below 200 °C. Motivated by our previous study based on a model slurr…
Potassium and phosphorus represent inorganics commonly found in biomass and can significantly affect catalytic gasification of biomass. The alkaline and acidic nature of potassium and phosphorus, respectively, can introduce different reaction chemistries. In this paper, the effects of potassium and phosphorus on Rh ca…
Efisiensi pemakaian energi untuk suatu kebutuhan harus dilakukan agar pemborosan energi dapat dihindarkan dengan melakukan pemilihan dan pemeliharaan peralatan logam. Korosi menjadi permasalahan utama pada industri minyak bumi dan gas karena dapat menghambat proses produksi. Korosi retak tegang (SCC, Stress Corrosion…
An innovative design of magnetic coupler for shaft speed amplification is proposed and verified by experiments. The structure of proposed magnetic coupler is similar to an infinite-stage gearbox. In addition, the mathematical model of flux density is derived to look into the equation of adjustable gear ratio and effec…
The structure of P3HT in P3HT:PCBM films is examined on a poly(3,4-ethylenedioxythiophene) polystyrene sulfonate ( PEDOT: PSS) substrate subjected to cryo-cooling to low temperature (-143 °C) followed by gradual heating to 50 °C. The behavior of these systems is examined in the absence and presence of an Al electrode…
homogenizer was shown as high quality.This technique should be recommended for fish oil liposome processing in food supplement.
Interactions between calcium and phosphorus salts, graphene oxide (GO), and collagen (COL) in aqueous solutions have been studied in the CaCl2–(NH4)2HPO4–NH3–H2O–GO–COL system (25°C) using the solubility (residual concentrations) method and pH measurements. Syntheses were shown to yield composites comprising nanocryst…
Rare earths containing end-product materials for commercial use or for research applications are numerous. A complete description of the most popular among these materials was given in the section on applications of rare earths in Chapter 1. These materials can be basically divided into two groups. One group comprises…
We conducted a comparative study of three widely used algorithms for the detection of fiducial markers in electron microscopy images. The algorithms were applied to four datasets from different sources. For the purpose of obtaining comparable results, we introduced figures of merit and implemented all three algorithms…
Abstract New tridentate N,N,O‐type ligands MeN(CH2CH2NHTs)(CH2CR2OH) [Ts = tosyl ; R = H, 6, (N,N,OH)H2; R = Ph, 7 (N,N,OPh)H2] were prepared. The corresponding diisopropoxide complexes (N,N,OH)Ti(OiPr)2 (8) and [N,N,OPh]Ti(OiPr)2 (9) were obtained through the reactions of 6 and 7 with Ti(OiPr)4. These complexes are t…
近年の柔軟剤や衣料用洗剤などのファブリックケア製品には，香りの品揃えが多く見られ，これらが生活者の購買意欲を高める一因になっている．ファブリックケア製品において香りは重要な役割を占めるようになり，製品のイメージやコンセプトを伝えること，様々な使用場面での使い心地のよさを与えることやターゲット層の高い嗜好性に応えること等，付加価値を向上させる手段として進化してきた．本稿では，日本の柔軟剤と衣料用洗剤にフォーカスし，その香りの変遷と香りに対する生活者意識の変化について紹介する．
