PGGA: A predictable and grouped genetic algorithm for job scheduling [PDF]

open access: yes, 2006
This paper presents a predictable and grouped genetic algorithm (PGGA) for job scheduling. The novelty of the PGGA is twofold: (1) a job workload estimation algorithm is designed to estimate a job workload based on its historical execution records, (2 ...

Commercial fire-retarded PET formulations - relationship between thermal degradation behaviour and fire-retardant action [PDF]

open access: yes, 2007
Many types of fire-retardants are used in poly(ethylene terephthalate), PET, formulations, and two commercial fire retardants, Ukanol(TM) and Phosgard(TM), have been shown to improve significantly PET flame-retardancy when used as comonomers.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

The Effects of Intralayer Metal Composition of Layered Double Hydroxides on Glass Transition, Dispersion, Thermal and Fire Properties of Their PMMA Nanocomposites [PDF]

open access: yes, 2009
A series of aluminum-containing layered double hydroxides (LDHs), containing Mg, Ca, Co, Ni, Cu and Zn as the divalent metals, have been prepared by the co-precipitation method and used to prepare nanocomposites of PMMA by in situ bulk polymerization ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

In situ synthesis, crystal structures, topology and photoluminescent properties of poly[di-μ-aqua-diaqua[μ3-4-(1H-tetrazol-1-id-5-yl)benzoato-κ4O:O,O′:O′′]barium(II)] and poly[μ-aqua-diaqua[μ3-4-(1H-tetrazol-1-id-5-yl)benzoato-κ4O:O,O′:O′]strontium(II)]

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2020
Two alkaline-earth coordination compounds, [Ba(C8H4N4O2)(H2O)4]n, (I), and [Sr(C8H4N4O2)(H2O)3]n, (II), from the one-pot hydrolysis transformation of benzoyl chloride and the in situ self-assembled [2 + 3] cycloaddition of nitrile are presented.

Astroglial inhibition of NF-κB does not ameliorate disease onset and progression in a mouse model for Amyotrophic Lateral Sclerosis (ALS) [PDF]

open access: yes, 2011
Motor neuron death in amyotrophic lateral sclerosis (ALS) is considered a “non-cell autonomous” process, with astrocytes playing a critical role in disease progression. Glial cells are activated early in transgenic mice expressing mutant SOD1, suggesting

3D‐Printed Sulfur‐Derived Polymers With Controlled Architectures for Lithium‐Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Rheology‐guided formulation design for direct ink writing enables the fabrication of 3D sulfur copolymer cathodes with controlled architectures for lithium‐sulfur batteries. The printed electrodes exhibit multiscale porosity and high sulfur utilization, delivering enhanced electrochemical performance compared to conventional cast electrodes.
