Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customize…
Abstract Metal‐organic chemical vapor deposition of zinc oxide (ZnO) using diethylzinc (DEZn) and triplet oxygen ( 3 O 2 ) is investigated at density functional theory level. The structures of reactants, transition states, intermediates, products, and the possible spin conversion points where singlet and triplet poten…
The paper presents the results on sulfate‐reducing bacteria (SRB) induced corrosion of 2205 duplex stainless steel (DSS) in as‐received and thermally aged conditions. Biofilm formation and damage process stimulated by DSM642 strain were analyzed with reference to its metabolic activity and to the surface characterizat…
Ti-5Al-2.5Sn alloy is widely used in aerospace applications due to its high specific strength, low coefficient of thermal expansion and good corrosion resistance. Presence of interstitial elements in the alloy has some significant effects on its properties. However the high notch toughness and cryogenic ductility attr…
At many universities, silver nitrate is used in teaching laboratories, and a resulting waste product is often silver chloride. Silver chloride is not a compound that can be discarded into a sink as it has harmful effects to the environment; however, commercial waste disposal is costly, and replacement of the silver ni…
Low-frequency (∼2 Hz) current self-oscillations were first obtained in a millimeter-sized two-terminal planar device with a vanadium dioxide (VO2) film. The film temperature distribution dynamics was investigated within one oscillation period. It was established that the formation and disappearance of a conductive cha…
Abstract The current range of medical applications of resorbable polyesters could be hugely expanded if more effective strategies for tailoring degradation rate were available. Block copolymerisation with poly(ethylene glycol) (PEG) has been shown to reduce degradation times; however, to date, this has relied on the a…
A poly(amic acid) (PAA) solution in xylene was prepared for electrospinning in order to fabricate fibers. However, jet breaking occurred at the point of the occurrence of whipping instability, resulting in forming micro-particles. This was an exceptional jet behavior compared with the general electro-spraying process…
In this paper, wire beam electrode method combined with other analysis methods, that is, electrochemical impedance spectroscopy, scanning electron microscope, and X‐ray photoelectron spectroscopy, was used to investigate effects of metabolic activity of sulphate‐reducing bacteria (SRB) on heterogeneous corrosion behav…
The lack of scalable and sustainable methods to prepare conjugated polymers belies their importance in many enabling technologies. Accessing high-performance poly(hetero)arene conjugated polymers by dehydration has remained an unsolved problem in synthetic chemistry and has historically required transitional-metal cou…
Abstract The effect of lanthanum (La) content on the phase transformation of Pb 1−3 x /2 La x (Zr 0.42 Sn 0.40 Ti 0.18 )O 3 ( PLZST 100x/42/40/18, 0 ≤ x ≤ 0.06) ceramics was investigated by the dielectric and ferroelectric properties. The base composition PLZST 0/42/40/18 located in the ferroelectric ( FE ) rhombohedr…
Mg-6.0Gd-1.2Cu-1.2Zr (wt-%) alloy was designed and prepared by gravity casting, then the ingots were solution treated at different temperatures. The microstructures of the as-cast and solution-treated alloys were observed by optical microscopy (OM) and scanning electron microscopy (SEM). Corrosion behaviors were evalu…
Abstract The complexes [FeL N2S2 X] [in which L N2S2 =2,2′‐(2,2′‐bipryridine‐6,6′‐diyl)bis(1,1′‐diphenylethanethiolate) and X=Cl, Br and I], characterized crystallographically earlier and here ( Fe(L)Br ), reveal a square pyramidal coordinated Fe III ion. Unusually, all three complexes have intermediate spin ground st…
Abstract Magnetic phase switching in a coordination polymer is reported, which is demonstrated by combining two processes: (A) the pre‐organization of magnetic/redox‐active molecules into a framework, and (B) a post‐treatment through electrochemical tuning of the pre‐organized molecules. A TTF .+ –TCNQ .− salt (TTF=te…
Zinc oxide nanoparticles (ZnO NPs) are used as antifungal agents and imparted in starch paste. The zinc oxide nanoparticles are synthesized using starch as a stabilizing agent under sonochemical irradiation, and then used in the preparation of ZnO NPs‐based starch paste. The effects of starch and ultrasonic irradiatio…
The adsorption distribution of porphyrin dye on the inorganic surface was examined by the use of Förster resonance energy transfer (FRET). Because the efficiency of FRET depends on the distance between energy donor and acceptor, FRET could be used as a spectroscopic molecular ruler to estimate the adsorption distribut…
The development of stable and active gold catalysts has arisen as a significant strategy for oxidation of alcohols. Nano-size PVA-stabilized gold nanoparticles immobilized on Sr(OH)2 by colloidal deposition presented high catalytic activity for benzyl alcohol oxidation. In 2.5 h, 2 bar of O2 and without extra-base add…
Many research groups have attained slow, persistent, continuous release of silver ions through careful experimental design using existing methods. Such methods effectively kill planktonic bacteria and therefore prevent surface adhesion of pathogens. However, the resultant modified coatings cannot provide long-term ant…
A novel pH‐responsive magnetic nanogels were developed with the aim of targeted delivering and simultaneously releasing of newly synthesized Au(III)‐based anticancer drug, Au(1,7‐Phen)Br 3 . The obtained nanogels were characterized by FT‐IR, DLS, EDAX, TEM, XRD, ICP‐Ms and MRI. The TEM images showed that the nanogels…
Abstract We performed dynamic Monte Carlo simulations of a lattice polymer model to investigate strain‐induced crystallization behaviors of short‐chain branched polymers with variable sequence distributions, branch numbers and lengths, and their blending compositions with linear polymers. The results revealed that the…
