This study investigated the effect of nitriding time and temperature on the mechanical properties of the composite AlN/Fe2-3N coating deposited on the pure aluminium substrate using the novel Active Screen Plasma Nitriding (ASPN) method. ASPN treatment was performed for 2, 5, 10, 15 h at tempera...

Using density functional theory computations, the structures and electronic properties of hydrogenated and fluorinated aluminium nitride (AlN) were systematically investigated. We found that fully hydrogenated AlN (H–AlN–H) is an indirect-bandgap semiconductor which is similar to an AlN monola...

In this work, we report on the novel fabrication of aluminum nitride (AlN) components using Binder Jetting (BJT) additive manufacturing (AM). The AlN constructs were subjected to post-fabrication thermal treatment by hot isostatic pressing (HIPing) for 8 hours at a pressure of 206 MPa and temper...

The study aims to identify the potential acute effects of suspended aluminum nitride (AlN) nanoparticles (NPs) on soluble microbial products (SMP) of activated sludge. Cultured activated sludge loaded with 1, 10, 50, 100, 150 and 200 mg/L of AlN NPs were carried out in this study. As results sho...

Aluminum nitride (AlN) ceramics have attracted broad interest due to their potential applications in electronics. Additive manufacturing of ceramic components are rapidly advancing, could provide a new way of manufacturing over conventional methods. Non-destructive testing of 3D printed ceramic ...

Aluminum nitride (AlN) nanowires were performed on iron substrate using aluminum powders as material precursor by anhydrous aluminum chloride (AlCl3) assisted chemical vapor reaction (CVR) method. Yield production of AlN nanowires was significantly enhanced with AlCl3 addition into Al powders du...

Adopting first-principles density function theory (DFT) calculations, the effects of TMO3 (TM = Ti, Cr, Mn, Fe, Co and Zn) cluster substitution on the physical parameters of monolayer AlN are investigated. Through charge difference diagrams it is seen that, TMO3 clusters lend their charge carrie...

A wearable, flexible and non-toxic pH sensor was fabricated by assembling a cotton fabric treated with an organically modified silicate (ORMOSIL) together with a miniaturized and low-power electronics with wireless interface. The pH sensible ORMOSIL was obtained via sol–gel by using litmus, a n...

Litmus-type sensors capable of detecting temperature and organic solvents have been developed with α-synuclein amyloid fibrils and 10,12-pentacosadiynoic acid (PCDA). The PCDA molecules localized on the amyloid fibrils through either co-incubation with monomeric α-synuclein (AF/PCDA) or simple...

Different inflammatory diseases and allergic reactions are mediated by leukotrienes, which arise from the oxygenation of arachidonic acid catalyzed by 5-lipoxygenase (5-LO). One promising approach for an effective anti-leukotriene therapy is the inhibition of this key enzyme. This study presents...

Three dipeptide complexes of the form K[M(dipeptide)Cl] (H2dipeptide=glycylβ-alanine, β-alanylglycine, β-alanylβ-alanine) and four dipeptide methyl ester complexes of the form K[M(dipeptideOMe)Cl2] (HdipeptideOMe=glycylα-alanine methyl ester, α-alanylglycine methyl ester, diα-alanine meth...

A series of N-(p-ethynylbenzoyl) derivatives (1–4) of the amino acids glycine and l-alanine as well as the dipeptides glycylglycine and l-alanylglycine has been synthesized via a two-step reaction sequence including the reaction of an appropriate N-(p-bromobenzoyl) precursor with trimethylsilyl...

The palladium(II)-promoted hydrolysis of the methyl esters of glycyl-L-leucine, glycyl-L-alanine and L-alanylglycine have been studied at 25 °C and I=0.1 M in the pH range 4–5. At a 1:1 metal to ligand ratio the peptide esters act as tridentate ligands, donation occurring via the terminal amin...

A new zinc phthalocyanine, ZnPc 1, bearing six bulky tert-octylphenoxy groups in peripheral positions, acting as pushing moieties, and an electron-withdrawing carboxyphenyl append, acting as anchoring unit to bind TiO2 surface, has been synthesized and characterized. ZnPc 1 has been employed as ...

Direct and indirect (sensitized) photolysis of p-tert-octylphenol (OP), 4-octylphenoxy-acetic acid (OP1EC), and ibuprofen (IBU) were investigated in laboratory water and surface water under simulated and natural sunlight conditions. Photodegradation obeyed apparent-first order kinetics with rate...

The methoxymethoxy substituent when attached to an aromatic ring functions as a moderately strong ortho-directing group in hydrogen-metal exchange reactions. In many cases the propensity of the methoxymethoxylated arene toward ring metallation is greatly enhanced with concomitant suppression of ...

A total of 31 of thiourea derivatives was prepared reacting 3-(trifluoromethyl)aniline and commercial aliphatic and aromatic isothiocyanates. The yields varied from 35% to 82%. All compounds were evaluated in vitro for antimicrobial activity. Derivatives 3, 5, 6, 9, 15, 24 and 27 showed the high...
