AIM: Myocardial infarction is caused after impairment of heart wall muscle following an immense cell loss and also when the myocardial tissue is lacking the inherent capacity to regenerate for normal functioning of myocardium. An immediate challenge in cardiac regeneration is to devise a strategy that leads to a repro…
In this study, a rigorous methodology for quantifying recrystallization kinetics by electron backscatter diffraction is proposed in order to reduce errors associated with the operator's skill. An adaptive criterion to determine adjustable grain orientation spread depending on the recrystallization stage is proposed to…
A modified 6-phosphofructo-1-kinase was expressed in a citrate producing Aspergillus niger strain in combination with cis-aconitate decarboxylase from Aspergillus terreus to study the effect on the production of itaconic acid. The modified pfkA gene was also expressed in combination with the itaconic acid biosynthetic…
This study investigated the requirement of cellobiohydrolases (CBH) for saccharification of microcrystalline cellulose and sugarcane bagasse pretreated either by ball milling (BM) or by ionic liquid (IL) [Emim][Ac]. Hydrolysis was done using CBH-free blends of Pyrococcus horikoshii endoglucanase (EG) plus Pyrococcus f…
Metal–organic frameworks (MOFs) are a highly versatile class of crystalline porous materials. In recent years, many diverse MOF materials have been experimentally realized, exhibiting a wide range of underlying topologies. In this work, we guide material design efforts by identifying the most promising MOF topologies…
Cobalt (10 wt %) was supported on KOH-activated Ca-type montmorillonite (Ca-MMT) as a catalyst for Fischer–Tropsch (FT) synthesis. The material was systematically characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, X-ray fluorescence (XRF), scanning electron microscopy (SEM), N 2…
Abstract This study used a nanoindentation technique to explore the local nanoscale mechanical properties of material phases and interfaces in an asphalt concrete composite. Regions of aggregate and mastic and their interfaces were nanoindented, and the load-displacement curves were analyzed to calculate the elastic m…
Strong dependence of the quantum yield of electron injection, Φ injection, on the excess vibrational energy of the short-lived S 1 excited state of the donor was observed for a carboxyazulene chromophore, 6-MeAz-2-COOH, bound to the surface of colloidal TiO 2 . The oxidation state of 6-MeAz-2-COOH was aligned with the…
We investigated the magnetic properties of the antiferromagnetic (AFM) compound Gd$T$${}_{2}$Al${}_{10}$ ($T=\text{Ru}$ and Fe). Although GdRu${}_{2}$Al${}_{10}$ could be understood well as a simple AFM compound, the exchange interaction in GdFe${}_{2}$Al${}_{10}$ is found to be greatly varied with temperature. The ma…
Anisotropic nanoparticles (i.e., silver nanocubes) were functionalized with target-specific antibodies and Raman active tags to serve as nanoprobes for the rapid detection of bacteria in a test-in-a-tube platform. A self-referencing scheme was developed and implemented in which surface enhanced Raman spectroscopic (SE…
Mutations in superoxide dismutase 1 (SOD1) associated with familial amyotrophic lateral sclerosis induce misfolding and aggregation of the protein with the inherent propensity of mutant SOD1 to aggregate generally correlating, with a few exceptions, to the duration of illness in patients with the same mutation. One no…
Reactive, but not a reactant. Heterogeneous catalysts play an unseen role in many of today's processes and products. With the increasing emphasis on sustainability in both products and processes, this handbook is the first to combine the hot topics of heterogeneous catalysis and clean technology. It focuses on the dev…
Photochromic proteins, such as Dronpa, are of particular importance in bioimaging and form the basis of ultraresolution fluorescence microscopy. The photochromic reaction involves switching between a weakly emissive neutral trans form of the chromophore (A) and its emissive cis anion (B). Controlling the rates of swit…
We report on photo-thermal modulation of thin film surface plasmon polaritons (SPP) excited at telecom wavelengths and traveling at a gold/air interface. By operating a modulated continuous-wave or a Q-switched nanosecond pump laser, we investigate the photo-thermally induced modulation of SPP propagation mediated by…
Absolute cross sections for the K -shell photoionization of Be-like and Li-like atomic nitrogen ions were measured by employing the ion–photon merged-beam technique at the SOLEIL synchrotron radiation facility in Saint-Aubin, France. High-resolution spectroscopy at nominal resolutions of 38, 56, 111, 133 meV full widt…
The objective of this study was to evaluate the influence of solid lipid nanoparticles (SLN) loaded with the poorly water-soluble drug tamoxifen citrate (TC) on the in vitro antitumor activity and bioavailability of the drug. TC-loaded SLN were prepared by solvent injection method using glycerol monostearate (GMS) or…
Doping nematic liquid crystals with optically active compounds transforms them into chiral nematic phases with helical structures. In this phenomenon, the chirality of the dopant molecules is transferred or amplified to the bulk of the liquid crystals. Δ-[Ru(acac)3] (acac = acetylacetonato) is known to work as one of…
ABSTRACT The study is focused on windshield recycling process resulting in poly(vinyl butyral) (PVB) sheets with very low amout of remain glass particles. PVB sheets were obtained from worldwide manufacturer DuPont and then they were laminated by standard autoclaving process. One sample of PVB sheet was modified by mu…
A novel multiple step growth (MSG) process has been developed to synthesize rutile nanorods (NRs) on fluorine-doped tin oxide (FTO) glass with the assistance of a self-assembled monolayer (SAM) aiming to increase the internal surface area of the 1D materials for dye sensitized solar cell (DSSC) applications. The exper…
Auf kleinstem Nenner: Palladiumcluster mit drei oder vier Atomen erwiesen sich als katalytisch aktive Spezies in ligandenfreien palladiumkatalysierten C-C-Kupplungen (siehe Bild). Die Cluster konnten in Wasser stabilisiert und ohne Aktivitätseinbuße lange Zeit aufbewahrt werden. Hohe Produktausbeuten und Umsatzfrequen…
