Cavitation in Poly(4-methyl-1-pentene) during Tensile Deformation

Chen, Ran; Lu, Ying; Jiang, Zhiyong; Men, Yongfeng

The poly(4-methyl-1-pentene) sample was used to investigate the cavitation-induced stress-whitening phenomenon during stretching at different temperatures via the ultrasmall-angle X-ray scattering technique. Two modes of cavitation were found that mode I cavitation activated around yield point followed by mode II cavitation generated in highly oriented state. The critical strain for…

Highly Selective Continuous Flow Hydrogenation of Cinnamaldehyde to Cinnamyl Alcohol in a Pt/SiO2 Coated Tube Reactor

Bai, Yang; Cherkasov, Nikolay; Huband, Steven; Walker, David; Walton, Richard; Rebrov, Evgeny;

A novel continuous flow process for selective hydrogenation of α, β-unsaturated aldehyde (cinnamaldehyde, CAL) to the unsaturated alcohol (cinnamyl alcohol, COL) has been reported in a tube reactor coated with a Pt/SiO2 catalyst. A 90% selectivity towards the unsaturated alcohol was obtained at the aldehyde conversion of 98.8%. This is…

Chandran, Bevita K.; Veldhuis, Sjoerd A.; Chin, Xin Yu; Bruno, Annalisa; Yantara, Natalia; Chen, Xiaodong; Mhaisalkar, Subodh

High photoluminescence quantum yields and narrow emission wavelengths, combined with low temperature solution processing, make CH3NH3PbBr3 nanocrystals (NCs) favorable candidates for light-emitting applications. Herein, we describe the synthesis of CH3NH3PbBr3 NC inks by a convenient room-temperature ligand assisted reprecipitation protocol. We further investigate the effect of modulation of the…

Effects of oxidation on the physicochemical properties of polyunsaturated lipid membranes

Parra-Ortiz, Elisa; Browning, Kathryn L.; Damgaard, Liv S. E.; Nordström, Randi; Micciulla, Samantha; Bucciarelli, Saskia; Malmsten, Martin

The exposure of biological membranes to reactive oxygen species (ROS) plays an important role in many pathological conditions such as inflammation, infection, or sepsis. ROS also modulate signaling processes and produce markers for damaged tissue. Lipid peroxidation, mainly affecting polyunsaturated phospholipids, results in a complex mixture of oxidized products, which…

Characterization of multi-scale structure and thermal properties of Indica rice starch with different amylose contents

Li, Zhihang; Kong, Xiangli; Zhou, Xianrong; Zhong, Kui; Zhou, Sumei; Liu, Xingxun

Fully understanding the relationship between multi-scale structure and thermal properties of rice starch is important for starch-based food processing. Multi-scale structures of Indica rice starch were studied from molecules to aggregation structure. Gel-permeation chromatography (GPC) and high-performance anion-exchange chromatography (HPAEC) both show that the amylopectin from debranched rice…

Effects of calcination and activation conditions on ordered mesoporous carbon supported iron catalysts for production of lower olefins from synthesis gas

Oschatz, M.; Deelen, T. W. van; Weber, J. L.; Lamme, W. S.; Wang, G.; Goderis, B.; Verkinderen, O.; Dugulan, A. I.; Jong, K. P. de

Lower C2–C4 olefins are important commodity chemicals usually produced by steam cracking of naphtha or fluid catalytic cracking of vacuum gas oil. The Fischer–Tropsch synthesis of lower olefins (FTO) with iron-based catalysts uses synthesis gas as an alternative feedstock. Nanostructured carbon materials are widely applied as supports for the iron…

Contribution to Accurate Spherical Gold Nanoparticle Size Determination by Single-Particle Inductively Coupled Mass Spectrometry: A Comparison with Small-Angle X-ray Scattering

Geertsen, Valérie; Barruet, Elodie; Gobeaux, Frédéric; Lacour, Jean-Luc; Taché, Olivier

Small-angle X-ray scattering spectroscopy (SAXS) is the method of choice for nanoparticle diameter and concentration determination. On the one hand, it is metrologically traceable for spherical nanoparticle mean diameter determination and does not require any sample preparation or calibration. On the other hand, single-particle inductively coupled mass spectrometry (SPICPMS) is…

Strengthening mechanisms in Fe-Al based ferritic low-density steels

Pramanik, Sudipta; Koppoju, Suresh; Anupama, A. V.; Sahoo, Balaram; Suwas, Satyam

Low-density steels with different aluminium contents have been investigated with an aim to examine the occurrence of different strengthening mechanisms leading to its higher strength. A composition corresponding to 6.8wt% aluminium has been studied to understand the underlying strengthening mechanisms. Different factors contributing to the strengthening mechanisms have been separately…
