The cross-metathesis of methyl oleate with cis-2-butene-1,4-diyl diacetate and the influence of protecting groups

open access: yesBeilstein Journal of Organic Chemistry, 2011
Background: α,ω-Difunctional substrates are useful intermediates for polymer synthesis. An attractive, sustainable and selective (but as yet unused) method in the chemical industry is the oleochemical cross-metathesis with preferably symmetric ...

The three species monomer-monomer model in the reaction-controlled limit

open access: yes, 1998
We study the one dimensional three species monomer-monomer reaction model in the reaction controlled limit using mean-field theory and dynamic Monte Carlo simulations.

Synthesis, Characterization, and Properties of Mononuclear and Dinuclear Ruthenium(II) Complexes Containing Phenanthroline and Chlorophenanthroline [PDF]

open access: yes, 2013
The study of photophysical and photochemical properties of ruthenium complexes is of great interest for fundamental practical reasons. Ruthenium complexes have been investigated for use in artificial photosynthesis.

Investigation of Thermodynamics of its 3-Butadiene Monomeric Derivatives with Nanoparticles of Fullerenes, Nanotubes and Nano Cones at Room Temperature by DFT Method [PDF]

open access: yesInternational Journal of New Chemistry, 2017
In this study, trans-3-butadiene monomer derivatives with different carbon nanoparticles of the same mass (mass mass) under different temperature conditions were studied using density functional theory.

Heat resistant polymers of oxidized styrylphosphine [PDF]

open access: yes, 1978
Homopolymers, copolymers and terpolymers of a styrene based monomer are prepared by polymerizing at least one oxidized styrylphosphine monomer or by polymerizing p-diphenylphosphinestyrene and then oxidizing the polymerized monomer with an organoazide ...

A Pfaffian formula for monomer-dimer partition functions

open access: yes, 2016
We consider the monomer-dimer partition function on arbitrary finite planar graphs and arbitrary monomer and dimer weights, with the restriction that the only non-zero monomer weights are those on the boundary.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Imenovanje jednonitnih homopolimera i kopolimera na osnovi podrijetla (I. dio) [PDF]

open access: yesKemija u Industriji, 2018
Prethodne IUPAC-ove preporuke imenovanja (nomenklature) jednonitnih polimera na osnovi podrijetla (NOP) odnosile su se uglavnom na kopolimere, nelinearne polimere, združene polimere i generičke polimere.

Microphase Separation within a Comb Copolymer with Attractive Side Chains: A Computer Simulation Study [PDF]

open access: yes, 2001
Computer simulation modelling of a flexible comb copolymer with attractive interactions between the monomer units of the side chains is performed. The conditions for the coil-globule transition, induced by the increase of attractive interaction, ε ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

open access: yesFEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...
