Graphene has been attracting great interest because of its distinctive band structure and physical properties. Today, graphene is limited to small sizes because it is produced mostly by exfoliating graphite. We grew large-area graphene films of the order of centimeters on copper substrates by chemical vapor deposition using methane. The films are predominantly single-layer graphene, with a smal...

ABSTRACT A highly efficient sophorolipid (SL) fermentation process using dual lipophilic substrates (DLS) was developed. Using DLS consisting of palm oil and oleic acid in the flask with SL-producing yeast Starmerella bombicola, productivity yield SL improved 2.4 1.7 times, comparison to when olein alone. In jar DLS, 127 g/L 62.4% were achieved 7 days, complete consumption residual culture medi...

AAA+ proteases utilize ATP hydrolysis to actively unfold substrate proteins and translocate them into a protease chamber for degradation. This activity results in the removal of misfolded control regulatory circuits cells. Among bacterial proteases, FtsH is only membrane-integrated, plays pivotal role membrane protein quality control. ranked as weakest unfoldase among degrading water-soluble su...

CO2 Electroreduction In article number 2203138, Zhonglong Zhao and Gang Lu predict that noble metal monolayers supported by transition carbides (TMCs) nitrides (TMNs) could be selective catalysts for the carbon dioxide reduction reaction with suppressed hydrogen evolution reaction. Dual-site functionalization induced antibonding interactions between TMC/TMN substrates is identified, which can c...

‎in this paper‎, ‎first we develop the duality concept for $g$-bessel sequences‎ ‎and bessel fusion sequences in hilbert spaces‎. ‎we obtain some results about dual‎, ‎pseudo-dual ‎and approximate dual of frames and fusion frames‎. ‎we also expand every $g$-bessel ‎sequence to a frame by summing some elements‎. ‎we define the restricted isometry property for ‎$g$-frames and generalize some resu...

We report on the fabrication of coplanar dual-gate ZnO thin-film transistors with 200-nm thickness SiNx for both top and bottom dielectrics. The ZnO film was deposited by RF magnetron sputtering on SiO2/Si substrates at 100◦C. And the thickness of ZnO film is compared with 100-nm and 40-nm. This TFT has a channel width of 100-μm and channel length of 5-μm. The fabricated coplanar dual-gate ZnO ...

in this paper the concept of homothetic dual exponential motions in d3 is discussed and theirvelocities obtained. due to the way in which the matter is presented, the paper gives some formula and factsabout dual exponential motions which are not generally known

in this paper, two new hamilton operators are defined and the algebra of dual split quaternions isdeveloped using these operators. it is shown that finite screw motions in minkowski 3-space can be expressedby dual-number ( 3×3 ) matrices in dual lorentzian space. moreover, by means of hamilton operators, screwmotion is obtained in 3-dimensional minkowski space 3r1
