Several bacteria and archaea utilize the amino group-carrier protein, LysW, for lysine biosynthesis, in which an isopeptide bond is formed between the C-terminal Glu of LysW and an amino group of α-aminoadipate (AAA). The resulting LysW-γ-AAA is phosphorylated by LysZ to form LysW-γ-AAA phosphate, which is subsequentl…
The influence of the shearing process on the iron loss of non-oriented electrical steels with grain sizes of 10 μm-150 μm was investigated. The deterioration ratio of iron loss was clearly smaller in sample with small grain sizes. The droop height, reflecting the amount of plastic deformation, displayed a good relatio…
One of the trends in hydrogen power engineering is the development of devices for the preparation of synthesis gas by the catalytic reforming of a hydrocarbon feedstock. Studies show the advantages of catalytic converters based on a modular catalyst support with a honeycomb-type structure produced from a metal foil, b…
Density functional theory method has been employed to investigate the adsorption of H 2 molecule and H atom on α ‐U(001) surface. There exist four initial sites [top (A), triangle‐center (B), long‐bridge (C), and short‐bridge (D)] for H 2 and H atom adsorptions on α ‐U(001) surface. The E ads (adsorption energy) value…
A comprehensive theoretical calculation for the complex first-order linear and the second-order non-linear optical dispersion of acentric lead nitrate hydroxide (Pb16(OH)16(NO3)16) single crystals was performed based on the experimental crystallographic data obtained by Chang et al. [Inorg. Chem. 53, 3320–3325 (2014)]…
The temperature dependences of the absorbance spectra of thin free-standing single-walled carbon nanotube (SWCNT) films were studied in the infrared range (700–6200 cm−1) while heating the air from 300 to 575 K. The observed temperature variation in the infrared absorbance spectra has been explained by two different p…
We report muon spin rotation experiments on the magnetic penetration depth $\ensuremath{\lambda}$ and the temperature dependence of ${\ensuremath{\lambda}}^{\ensuremath{-}2}$ in the over-doped Fe-based high-temperature superconductor (Fe-HTS) ${\mathrm{Ba}}_{1\ensuremath{-}x}{\mathrm{Rb}}_{x}{\mathrm{Fe}}_{2}{\mathrm{…
The present investigation aims to study the effect of degumming time on the structural property of silk fiber obtained by silk cocoons of Bombyx mori, followed by preparation of the regenerated silk fibroin (RSF) solution which can be subsequently molded into silk nanoparticles. Silk fibers degummed with different med…
Different polymeric films and various headspace conditions (air, vacuum and four different modified atmosphere packaging) were combined to select a packaging system that assured the desired shelf life for two types of portioned Canestrato di Moliterno cheese ripened for 4 and 12 months. To evaluate the quality deterio…
Abstract Free‐standing NiCo2O4@graphene 3D foams were prepared by using a controllable freeze‐casting method (CFC). In this designed method, the amount of water governs the size and shape of the ice upon introducing the material into a freeze‐drying system. By this means, controllable pore size and aligned nanostructu…
A neutron powder diffraction (NPD) study of $\mathit{Ln}\mathrm{MnSbO}$ ($Ln=\mathrm{La}$ or Ce) reveals differences between the magnetic ground state of the two compounds due to the strong Ce-Mn coupling compared to La-Mn. The two compounds adopt the P4/nmm space group down to 2 K, and whereas magnetization measureme…
Under infrared radiation, the upconversion emission spectra of Lu3-x-yYbxEryAl5O12 consisted of green and red emission bands that were attributed to the 2H11/2/4S3/2 → 4I15/2 and 4F9/2 → 4I15/2 transitions of the Er3+ ions, respectively; these transitions occurred by means of an energy transfer (ET) process from Yb3+…
Glutamate racemase (MurI) is responsible for providing D-glutamate for peptidoglycan biosynthesis in bacteria and has been a favoured target in pharmaceutical drug design efforts. It has recently been proven to be essential in Mycobacterium tuberculosis, the causative organism of tuberculosis, a disease for which new…
Ga2O3:Cr3+, In3+ phosphors, synthesized via a high temperature solid state reaction, exhibit photocatalytic activity and persistent luminescence. With substituting In3+ for Ga3+ in Ga2O3:Cr3+, the duration of near-infrared (NIR) persistent luminescence was prolonged obviously at room temperature under 254 nm ultraviol…
Controlling the organization of functional supramolecular materials at both short and long length scales as well as creating hierarchical patterns is essential for many biological and electrooptical applications. It remains however an extremely challenging objective to date, particularly in water‐based systems. In thi…
Alumina supports presenting a bimodal porosity are generally advantageous for the conversion of bulky molecules such as found in biomass, refining, and petrochemistry. However, shaping of such materials, while controlling pores size and orientation, proves to be hard. This problem can be tackled by using a simple meth…
Based on a first principles approach, we study structural, electronic and elastic properties, as well as stabilities of all possible half-oxidized phosphorene conformers. Stability analysis reveals that oxygen chemisorption is an exothermic process in the six configurations despite the formation of interstitial oxygen…
In the present century the small particles are unique phenomenon which can be developed by bottom-up and top-down processes. These small particles may be considered as nanoparticles which help to build up a technology called nanotechnology. Nanomaterials are those materials which possess the length scales below 100 nm…
Two-dimensional lattices of chiral nanoholes in a plasmonic film with lattice constants being slightly larger than light wavelength are proposed for effective control of polarization and spatial properties of light beams. Effective polarization conversion and strong circular dichroism in non-zero diffraction orders in…
The ability to control the degree of particle dispersion in polymer solutions has been a long-standing subject in colloidal science. While a generally accepted principle is that nonadsorbing polymers can induce depletion attraction, which is mostly temperature independent, the effects of adding adsorbing polymers are…
