Quantum Dot Light‐Emitting Diode (QD‐LED) has the disadvantage of charge imbalance due to deep HOMO level QD itself and layer mixing solution process despite its enormous advantage high color purity large display manufacturing. PEIE, introduced prevent this, uses harmful 2‐ME solvents, was evaluated replace them with IPA, a harmless solvent. As result, IPA secured more than twice EQE resolve co...
introduction: the aim of this study was to compare the effect of post space preparation with gates glidden drills or hand files on the sealing ability of gutta-percha or resilon obturation materials. materials and methods: one-hundred and four single-rooted human teeth were instrumented and divided into four experimental groups (n=21 each) and two groups of positive and negative control (n=10)....
in recent years, newly developed solvent-free dental adhesives have been introduced. the aim of this study was to evaluate the marginal integrity of a new one-step solvent-free self-etch adhesive and to compare it with a commonly used two-step self-etch adhesive as the gold standard.class v cavities (2×4×1.5 mm) were prepared on the buccal aspects of 28 human premolars. the cervical margins of ...

The temperature dependent solubility of 18 organic compounds, which some are active pharmaceutical ingredients, was measured in 1,4-dioxane, toluene and cyclopentyl methyl ether over a range between 0 70 °C using turbidity method. the studied compounds three solvents increases with all binary solute-solvent systems, exhibit higher 1,4-dioxane than ether. non-ideal behaviour systems evaluated te...
Considering the literature for aqueous rechargeable Zn//MnO2 batteries with acidic electrolytes using doctor blade coating of active material (AM), carbon black (CB), and binder polymer (BP) positive electrode fabrication, different types (non-)aqueous solvents were introduced so far. Furthermore, in most cases, relatively high passive (CB+BP) shares ~30 wt% applied. The first part this work fo...
Nanostructures due to their small size, in comparison with their bulk counterparts, possess unique properties including magnetic, electrochemical and photonic properties. Therefore, such nanomaterials found a wide variety of application in different fields such as catalysis, electronic and spintronics, life and material sciences. Controlling the morphology and structure of nanomaterials is of c...
published in lournal ofAutomatic Chemistry, Vol. 12, No. 6. not readily accepted because the apparatus was unreliable. However, the use of Bondelut cartridges was becoming increasingly popular and was the obvious next target for robotic automation. At this point, the decision was made to develop robotic systems, capable of executing any of our liquidor solidphase extraction methods. Also, singl...
We examined the harmful side effects on indigenous soil microorganisms of two organic solvents, acetone and dichloromethane, that are normally used for spiking of soil with polycyclic aromatic hydrocarbons for experimental purposes. The solvents were applied in two contamination protocols to either the whole soil sample or 25% of the soil volume, which was subsequently mixed with 75% untreated ...
Highly active, air-stable and water-soluble palladium-phosphinous acid complexes have been applied to Suzuki cross-coupling reaction of heteroaryl bromides under mild conditions in water/alcoholic solvents. Suzuki cross-coupling reaction of heteroaryl bromides with phenylboronic acid occurred efficiently using palladium phosphinous acid complexes (POPd) and phase transfer catalyst (tetrabutylam...
