A Riboflavin-Derived Flavinium Salt Mediates Chemoselective Methylation Reactions. [PDF]
ChemistryA two‐component methylation protocol was developed, where the active flavin mediator can be recycled in a single step. Crystallographic data and NMR spectroscopy support the mechanistic proposal, while chemoselective methylation was observed for a broad range of biologically relevant substrates. ABSTRACT Selective methylation is among the most relevant

Current-induced effective magnetic field in La0.67Sr0.33MnO3/LaAlO3/SrTiO3 structures
AIP Advances, 2020 We investigate the current-induced effective magnetic field Heff in La0.67Sr0.33MnO3 (18)/LaAlO3(0,2,6)/SrTiO3 (LSMO/LAO/STO) structures by using the planar Hall effect (PHE), where numbers in parentheses give the nominal thickness of the given layer in ...

JURNAL BIOS LOGOS, 2022 The brown plant hopper (Nilaparvata lugens. Stål.) is a pest of crops, especially rice crops worldwide and has been a problem for a long time. One of the reasons for the explosion of N. lugens was that it had developed resistance as a result of the inability of pesticides to suppress the growth of these insect pests. Utilization of the entomopathogenic

Generalized Berry Conjecture and mode correlations in chaotic plates
, 2004 We consider a modification of the Berry Conjecture for eigenmode statistics in wave-bearing systems. The eigenmode correlator is conjectured to be proportional to the imaginary part of the Green's function.

Plasmon mediated cathodic photocurrent generation in sol-gel synthesized doped SrTiO3 nanofilms
APL Materials, 2015 Thin films of SrTiO3 (STO) and Rh-doped SrTiO3 (Rh-STO) were synthesized by sol-gel method and loaded with Ag nanoparticles. Pristine STO films exhibited anodic photocurrent while Rh-STO exhibited cathodic photocurrent.

Što je atomska orbitala? [PDF]
Kemija u Industriji, 2018 Pojam atomske, odnosno molekulske orbitale osnovni je pojam kemije koji svoje potpuno tumačenje dobiva tek u okviru kvantne fizike. Atomska orbitala zapravo je pojam izveden iz pojma valne funkcije ili vektora stanja, koji su stoga prvi objašnjeni, uz ...

Energy Spectrum Evolution of a Diffuse Field in Elastic Body Caused by Weak Nonlinearity
, 2004 We study the evolution of diffuse elastodynamic spectral energy density under the influence of weak nonlinearity. It is shown that the rate of change of this quantity is given by a convolution of the linear energy at two frequencies.

Observation of Stückelberg oscillations in accelerated optical lattices [PDF]
Physical Review A, 2010 We report the experimental observation of St ckelberg oscillations of matter waves in optical lattices. Extending previous work on Landau-Zener tunneling of Bose-Einstein condensates in optical lattices, we study the effects of the accumulated phase between two successive crossings of the Brillouin zone edge. Our results agree well with a simple model
