Ma bamboo (Dendrocalamus latiflorus Munro) is the most distributed bamboo species in Taiwan, and its newly grown biomass within one growing season is the highest compared to the other local bamboo species. However, little is known about the cell wall chemical composition variations and distributions in Ma bamboo durin…
Post-translational modification by the addition of an oxoanion functional group, usually a phosphate group and less commonly a sulfate group, leads to diverse structural and functional consequences in protein systems. Building upon previous studies of the phosphoserine residue (pSer), we address the distinct nature of…
The twinning behaviour of Twinning-induced plasticity (TWIP) steel has been studied by analysing the grain orientation and the Taylor factor, based on microstructural and electron backscatter diffraction device observations. It is demonstrated that the Taylor factor can give an important guideline for determining the…
Molybdenum (Mo) is an essential trace element for almost all living organisms including animals. Mo is used as a catalytic center of molybdo-enzymes for oxidation/reduction reactions of carbon, nitrogen, and sulfur metabolism. Whilst living cells are known to import inorganic molybdate oxyanion from the surrounding en…
The fluorinated cationic guar gum (FCGG) was prepared with cationic guar gum (CGG) and fluorinated reactive monomer (FAM). FAM was synthesized from isophorone diisocyanate and 2,2,3,4,4,4-hexafluoro-1-butanol. The molecular structure, associating and rheological behaviors of FCGG were studied by the FT-IR, (19)F NMR,…
Within the Fock-space multi-reference coupled cluster framework, we have evaluated the electronic transition dipole moments, which determine absorption intensities. These depend on matrix elements between two different wave functions (e.g., ground state to the excited state). We present two different ways, to calculat…
Practical copper (Cu)‐based catalysts for the water–gas shift (WGS) reaction was long believed to expose a large proportion of Cu(110) planes. In this work, as an important first step toward addressing sulfur poisoning of these catalysts, the detailed mechanism for the splitting of hydrogen sulfide (H2S) on the open C…
Atomic impurities are critical for many technologies. They are used to engineer the optical and electronic properties of semiconductors for applications such as transistors, solar cells, light-emitting diodes (LEDs), and lasers, as well as to store energy for applications such as batteries and electrochemical cells. W…
In this paper, noncovalent functionalized graphene nanosheets are prepared through solvent-exfoliation expanded graphite with the aid of supercritical (SC) CO 2 and 1-pyrenamine (PA). Then, it is used as supporting materials for platinum to investigate the potential application of the obtained nanocomposite in direct…
A hybrid micro/meso forming assisted by high-frequency vibration was experimentally investigated by upsetting aluminum. Experiments with various vibration amplitudes and durations were conducted. The high-frequency vibration resulted in both acoustic softening and hardening behavior. Results showed that the overall fo…
Computational modeling and visualization studies were performed using computerized advanced programs. The theoretical investigations was succeeded to design Graphene-Graphite mixtures nano-surface catalyst to apply as nano-molecular sieving materials.The synthesized molecular sieving was carefully characterized by bot…
Abstract We report the advantages of the adsorption and electrooxidation of oligonucleotides and calf‐thymus double stranded DNA (dsDNA) at glassy carbon electrodes (GCE) modified with a dispersion of multiwalled carbon nanotubes (MWCNT) in poly‐L‐lysine (Plys) (GCE/MWCNT‐Plys). Important enhancement in the guanine ox…
With the aim to gain a wider understanding on the design rules of bioinspired adhesives for application in the medical field, the adhesion of fibrillar structures on soft and stiff polymers was determined in bench top studies on surfaces with variable roughness and in ex-vivo wet tissue tests. The adhesion strength of…
New Pd(Pt) catalysts have been fabricated by assembling multicomponents of Fe3O4 and CeO2/Pd(Pt) on the surface of reduced graphene oxide (RGO) nanosheets in layers. The as-obtained Pd(Pt) catalysts exhibit extremely high catalytic activity in the selective hydrogenation reaction of nitrobenzene. Owing to the presence…
Abstract Der Stand der Technik bei der Herstellung von Poly(propylencarbonat) ausgehend von Propylenoxid und Kohlenstoffdioxid wird vorgestellt. Thermodynamisch betrachtet ist Poly(propylencarbonat) ein kinetisches Produkt mit einer hohen Bildungsenthalpie. Nach jahrzehntelangen Entwicklungen sind einige vielversprech…
Abstract Raman spectra of rare earth (REE: rare earth elements) trichloride (REE = Y, La, Ce, Pr, Sm, Gd, Dy, or Yb) dissolved in alkali chloride eutectic melts (LiCl‐KCl, LiCl‐RbCl, and LiCl‐CsCl) were measured at 793 K. The spectra showed polarized peaks centered around 240–270 cm–1, which were identified as the tot…
Poly(m‐phenylenediamine)/ZnO (PMPD/ZnO) composites were successfully synthesized by chemical oxidative polymerization method. Powder X‐ray diffraction (XRD), Fourier‐transform infrared spectra (FTIR), transmission electron microscope, and UV–vis spectra (UV–vis) were used to characterize the prepared PMPD/ZnO composit…
Recent advances in developing donor–acceptor conjugated copolymers have led to great performance improvement in both organic photovoltaic cells and field-effect transistors. In contrast to the extensive spectroscopic studies on the photoinduced charge transfer and separation processes in these copolymers, little has b…
A synthetic strategy to prepare 2,7- or 4,9-functionalized cyclopenta[hi]aceanthrylenes that are capable of Suzuki cross-coupling reactions is demonstrated. This method has been utilized to create a series of thiophene derivatized compounds that were subsequently used to investigate the role of substitution pattern on…
