In this paper, we report on the effects of the substrate thermal evaporation process rotation speed on the electroluminescence (EL) characteristics of organic light-emitting diodes (OLEDs). In general OLED research, rotational and angle tilted deposition are widely used to maintain uniformity. However, there have been few reports on the effects of this deposition method on film characteristics. We analyzed these effects and found that the film d. and its refractive index showed remarkable changes as a function of substrate rotational speed during tilted deposition. The EL characteristics of the transport layer of fluorescent OLEDs were also significantly affected. We derived the OLED optimal thickness and refractive index from our calculations

Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring.

The authors investigated the ability of the angiotensin converting enzyme (ACE) inhibitor imidapril hydrochloride, and of the calcium channel blocker amlodipine besilate, to prevent nephrosclerosis and left ventricular hypertrophy (LVH) in rats with hypertension induced by chronic inhibition of nitric oxide (NO). Male Wistar rats were given distilled water (control), NG-nitro-L-arginine Me ester (L-NAME) 500 mg/L, L-NAME plus imidapril 10 mg/L or 100 mg/L, or L-NAME plus amlodipine 50 mg/L or 100 mg/L in the drinking water (n = 10-12). 24-H urine samples at 2, 4, and 6 wk were collected, blood samples at 6 wk were obtained, and histol. examined the kidney and heart were performed. L-NAME markedly reduced the levels of NO metabolites in serum and urine while increasing the tail-cuff blood pressure, the urinary albumin level (1.90 ± 0.65 v 0.05 ± 0.02 mg/day/100 g in control), and the area of the left ventricular wall (83.3 ± 3.0 v 69.8 ± 1.8 mm2 in control). Nephrosclerosis and myocardial interstitial fibrosis were documented histol. The plasma renin activity was significantly higher in rats treated with L-NAME than in the control rats. The concomitant administration of imidapril (10 mg/L) with L-NAME completely normalized the tail-cuff pressure, the LVH (70.8 ± 1.8 mm2), the albuminuria (0.05 ± 0.01 mg/day/100 g), and the histol. changes. Amlodipine (50 mg/L) also ameliorated the L-NAME-induced effects, but to a lesser extent. Thus, the chronic inhibition of NO synthesis in rats produced nephrosclerosis and LVH that were effectively prevented by giving imidapril at a dose lower than that of amlodipine. The authors conclude that ACE inhibitors can prevent nephrosclerosis and LVH even in the presence of a reduction in NO production, implying that in rats the inhibition of the renin-angiotensin system is more effective than the blockade of calcium channels in preventing hypertensive tissue injury.

The objective of the present study was to compare the effects of imidapril hydrochloride, an angiotensin converting enzyme inhibitor, and dilazep hydrochloride, an antiplatelet agent, on urinary protein excretion and renal function in patients with chronic glomerulonephritis. Imidapril (2.5 or 5 mg/day) or dilazep (300 or 450 mg/clay) was administered for 3 years. Blood pressure, proteinuria, and renal function were measured before and during the treatment. In the group administered imidapril (n = 11), urinary protein decreased by approx. 50% (2.16 ± 1.57 vs. 0.90 ± 0.53 g/g Cr, P < 0.01) and blood pressure by 14/10 mmHg (139.6 ± 17.4/93.6 ± 8.7 mmHg vs. 122.7 ± 10.5/81.8 ± 9.9 mmHg, P < 0.01) and both remained at low levels during the three years of treatment. No correlation was observed between the extent of blood pressure reduction and changes in urinary protein. Serum creatinine concentrations did not change significantly (1.3 ± 0.3 vs. 1.3 ± 0.3 mg/dL, NS). In the dilazep group (n = 12), there were no significant changes in blood pressure, urinary protein, or serum creatinine. These findings demonstrate that imidapril reduces proteinuria and contributes to preserve renal function, suggesting its usefulness in the treatment of patients with chronic glomerulonephritis.

Oral administration of TA/6366 (I), a new angiotensin-converting enzyme (ACE) inhibitor, decreased significantly mean arterial pressure in 2-kidney, 1 clip (2K1C) and 1-kidney, 1 clip (1K1C) renovascular hypertensive rats. The antihypertensive effect of I was almost as potent as that enalapril (II), but approx. 5 times more potent than that of captopril (III). The duration of action was almost similar among these 3 ACE inhibitors. The antihypertensive effect of I, II, or III was almost similar between in 2K1C and 1K1C, when they were treated with the same concentration I, II, and III had no substantial effect on the blood pressure in normal control rats. These results suggest that I is a potent antihypertensive agent in not only 2K1C but also 1K1C.

This article reports on the Ar+ ion irradiation induced modifications of Co/Alq3/Si-substrate bilayer thin film. Irradiation was carried out with 10 keV Ar+ ions at a fluence of 1 x 1016 ions/cm2. To study structural and magnetic modifications, x-ray reflectivity (XRR) and magneto-optical Kerr effect (MOKE) techniques, resp. have been utilized. XRR anal. reveals a significant reduction of electron d. of the Co layer and enhancement of intermixing of Co and Alq3 at the Co/Alq3 interface after ion irradiation MOKE measurements affirm that saturation magnetization reduces by a factor of about 3 due to irradiation without any detectable changes in the coercivity. XRR anal. and Monte Carlo simulation demonstrate the ion irradiation induced defects formation due to Ar implantation and enhancement of interface mixing between Co and Alq3 is the main cause of the reduction in saturation magnetization.

Compound: (S)-3-((S)-2-(((S)-1-Ethoxy-1-oxo-4-phenylbutan-2-yl)amino)propanoyl)-1-methyl-2-oxoimidazolidine-4-carboxylic acid hydrochloride(SMILESS: O=C([C@H](CN1C)N(C([C@@H](N[C@@H](CCC2=CC=CC=C2)C(OCC)=O)C)=O)C1=O)O.[H]Cl,cas:89396-94-1) is researched.Name: Aluminum triquinolin-8-olate. The article 《Purely in Silico BCS Classification: Science Based Quality Standards for the World’s Drugs》 in relation to this compound, is published in Molecular Pharmaceutics. Let’s take a look at the latest research on this compound (cas:89396-94-1).

BCS classification is a vital tool in the development of both generic and innovative drug products. The purpose of this work was to provisionally classify the world’s top selling oral drugs according to the BCS, using in silico methods. Three different in silico methods were examined: the well-established group contribution (CLogP) and atom contribution (ALogP) methods, and a new method based solely on the mol. formula and element contribution (KLogP). Metoprolol was used as the benchmark for the low/high permeability class boundary. Solubility was estimated in silico using a thermodn. equation that relies on the partition coefficient and m.p. The validity of each method was affirmed by comparison to reference data and literature. We then used each method to provisionally classify the orally administered, IR drug products found in the WHO Model list of Essential Medicines, and the top-selling oral drug products in the United States (US), Great Britain (GB), Spain (ES), Israel (IL), Japan (JP), and South Korea (KR). A combined list of 363 drugs was compiled from the various lists, and 257 drugs were classified using the different in silico permeability methods and literature solubility data, as well as BDDCS classification. Lastly, we calculated the solubility values for 185 drugs from the combined set using in silico approach. Permeability classification with the different in silico methods was correct for 69-72.4% of the 29 reference drugs with known human jejunal permeability, and for 84.6-92.9% of the 14 FDA reference drugs in the set. The correlations (r2) between exptl. log P values of 154 drugs and their CLogP, ALogP and KLogP were 0.97, 0.82 and 0.71, resp. The different in silico permeability methods produced comparable results: 30-34% of the US, GB, ES and IL top selling drugs were class 1, 27-36.4% were class 2, 22-25.5% were class 3, and 5.46-14% were class 4 drugs, while ∼8% could not be classified. The WHO list included significantly less class 1 and more class 3 drugs in comparison to the countries’ lists, probably due to differences in commonly used drugs in developing vs. industrial countries. BDDCS classified more drugs as class 1 compared to in silico BCS, likely due to the more lax benchmark for metabolism (70%), in comparison to the strict permeability benchmark (metoprolol). For 185 out of the 363 drugs, in silico solubility values were calculated, and successfully matched the literature solubility data. In conclusion, relatively simple in silico methods can be used to estimate both permeability and solubility While CLogP produced the best correlation to exptl. values, even KLogP, the most simplified in silico method that is based on mol. formula with no knowledge of mol. structure, produced comparable BCS classification to the sophisticated methods. This KLogP, when combined with a mean m.p. and estimated dose, can be used to provisionally classify potential drugs from just mol. formula, even before synthesis. 49-59% of the world’s top-selling drugs are highly soluble (class 1 and class 3), and are therefore candidates for waivers of in vivo bioequivalence studies. For these drugs, the replacement of expensive human studies with affordable in vitro dissolution tests would ensure their bioequivalence, and encourage the development and availability of generic drug products in both industrial and developing countries.

Synthetic Route of C27H18AlN3O3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Aluminum triquinolin-8-olate, is researched, Molecular C27H18AlN3O3, CAS is 2085-33-8, about External-heater-induced negative capacitance in electronic devices. Author is Okumoto, Hajime; Tsutsui, Tetsuo.

Neg. capacitance (NC) is considered an extraordinary phenomenon although it is observed in various electronic devices. Based on device-specific properties, numerous mechanisms have been proposed for decades to explain how ordinary pos. capacitance values reach neg. values at low frequencies under a high voltage bias. In a previous study, we demonstrated that ubiquitous self-heating of devices is a source of NC in organic light-emitting diodes (OLEDs) and hole-only devices. The principal mechanism of the NC is the nonlinear coupling of the real and imaginary parts of admittance, caused by AC temperature modulation. In this study, a simple test applicable to various devices was conducted to monitor the effects of heating on capacitance. External heating by nichrome wires, rather than self-heating, induced NC, which reflected the heat transfer characteristics of the devices considered: an OLED and a Schottky barrier diode. The heating effect was shown to be a basic and common mechanism of NC, independent of device-specific electronic properties. Therefore, self-heating effects must be considered prior to exploring device-specific NC sources in electronic devices.

Conventional IR spectroscopy is widely used to analyze the structural properties of compounds in the fingerprint region. However, a precise spectroscopic study of thin films is a nontrivial task due to the small absorption cross sections of analytes. In this regard, surface-enhanced IR absorption (SEIRA) spectroscopy can be applied to overcome the limitation by the near-field enhancement of plasmonic metasurfaces. Here, we present for the first time the SEIRA study of the widely used organic optoelectronic material Tris(8-hydroxyquinoline) aluminum(III) (Alq3). A special design of the metasurfaces based on arrays of gold Y-shaped nanoantennas is developed for the SEIRA study of Alq3 thermally deposited layers with film thickness growth. This design supports two independent plasmonic resonances for each metasurface and makes it possible to use one SEIRA substrate for the precise study of several vibrational modes of the compound Observed near-field enhancement of the fabricated metasurfaces revealed a saturation and a diminishing in signal with the analyte layer thickness from half the height of gold nanoantennas onward. This effect is associated with Alq3 side accumulation as shown by at. force microscopy. A fabricated SEIRA substrate indicates the possibilities for further progress of spectroscopic chem. imaging in optoelectronics and is especially promising for organic electronic devices that consist of multiple layers of transport materials.

Keywords: reflecting metagrating thin film organic emitting device. We’ll tell you more about this compound (cas:2085-33-8).

Organic light emitting diodes can achieve close to unitary internal quantum efficiency; however, their external quantum efficiency is much lower due to losses within the device. Gradient metasurfaces and metagratings can be utilized to achieve substantial electromagnetic field manipulation and enhancement of the local d. of photonic states, thereby improving the external quantum efficiency of organic light emitting devices. In this work, we show how suitably designed reflecting plasmonic metagratings can be potentially incorporated into a top-emitting organic light emitting device, resulting in large enhancement of light emissivity by effectively coupling out the light trapped in the waveguide modes. We describe how both periodic and quasiperiodic metagratings can be used to improve device performance. Electromagnetic simulations and measurements show that our metagratings greatly enhance the electromagnetic field intensity in the light emission layer, leading to increased emission normal to the plane of the layers (by up to a factor of 4.8) and suppression of light trapping typically lost into waveguide modes.
