Sensors, Vol. 16, Pages 219: Poly(Ionic Liquid) Semi-Interpenetrating Network Multi-Responsive Hydrogels

06.02.2016 | Tudor, Alexandru ; Florea, Larisa ; Gallagher, Simon ; Burns, John ; Diamond, Dermot, Sensors, 2016

Herein we describe poly(ionic liquid) hydrogel actuators that are capable of responding to multiple stimuli, namely temperature, ionic strength and white light irradiation. Using two starting materials, a crosslinked poly ionic liquid (PIL) and a linear ...

Materials, Vol. 9, Pages 101: Tungsten as a Chemically-Stable Electrode Material on Ga-Containing Piezoelectric Substrates Langasite and Catangasite for High-Temperature SAW Devices

06.02.2016 | Rane, Gayatri K.; Seifert, Marietta ; Menzel, Siegfried ; Gemming, Thomas ; Eckert, Jürgen, Materials, 2016

Thin films of tungsten on piezoelectric substrates La3Ga5SiO14 (LGS) and Ca3TaGa3Si2O14 (CTGS) have been investigated as a potential new electrode material for interdigital transducers for surface acoustic wave-based sensor devices operating at high temperatures up to 800 °C under vacuum ...

Materials, Vol. 9, Pages 105: Irradiation Induced Microstructure Evolution in Nanostructured Materials: A Review

06.02.2016 | Liu, Wenbo ; Ji, Yanzhou ; Tan, Pengkang ; Zang, Hang ; He, Chaohui ; Yun, Di ; Zhang, Chi ; Yang, Zhigang, Materials, 2016

Nanostructured (NS) materials may have different irradiation resistance from their coarse-grained (CG) counterparts. In this review, we focus on the effect of grain boundaries (GBs)/interfaces on irradiation induced microstructure evolution and the irradiation tolerance of NS materials under ...

IJMS, Vol. 17, Pages 223: Micellization Behavior of Long-Chain Substituted Alkylguanidinium Surfactants

06.02.2016 | Bouchal, Roza ; Hamel, Abdellah ; Hesemann, Peter ; In, Martin ; Prelot, Bénédicte ; Zajac, Jerzy, International Journal of Molecular Sciences, 2016

Surface activity and micelle formation of alkylguanidinium chlorides containing 10, 12, 14 and 16 carbon atoms in the hydrophobic tail were studied by combining conductivity and surface tension measurements with isothermal titration calorimetry. The purity of the resulting surfactants, their ...

Entropy, Vol. 18, Pages 54: Definition and Counting of Configurational Microstates in Steady-State Two-Phase Flows in Pore Networks

06.02.2016 | Valavanides, Marios S.; Daras, Tryfon, Entropy, 2016

Steady-state two-phase flow in porous media is a process whereby a wetting phase displaces a non-wetting phase within a pore network. It is an off-equilibrium stationary process—in the sense that it is maintained in dynamic equilibrium at the expense of energy supplied to the system. The ...

Influence of Water Activity on Thermal Resistance of Microorganisms in Low‐Moisture Foods: A Review

06.02.2016 | Roopesh M. Syamaladevi, Juming Tang, Rossana Villa‐Rojas, Shyam Sablani, Brady Carter, Gaylon Campbell, Comprehensive Reviews in Food Science and Food Safety, 2016

Abstract A number of recent outbreaks related to pathogens in low‐moisture foods have created urgency for studies to understand the possible causes and identify potential treatments to improve low‐moisture food safety. Thermal processing holds the potential to eliminate pathogens such as ...

Synthesis and Thermal Characterization of Precision Poly(p‐cyclohexylene alkylene)s via Acyclic Diene Metathesis Polycondensation

05.02.2016 | Lucas Caire da Silva, Kenneth B. Wagener, Macromolecular Chemistry and Physics, 2016

The synthesis and thermal characterization of poly(p‐cyclohexylene alkylene)s (PPCs) is described. Polymers containing 1,4‐cyclohexylene units on every 15th, 19th, and 21st chain carbon are prepared by the acyclic diene metathesis polycondensation of symmetric α,ω‐dienes obtained from the ...

Light and Strong SiC Networks

05.02.2016 | Claudio Ferraro, Esther Garcia‐Tuñon, Victoria G. Rocha, Suelen Barg, Maria Dolores Fariñas, Tomas E. Gomez Alvarez‐ ..., Advanced Functional Materials, 2016

The directional freezing of microfiber suspensions is used to assemble highly porous (porosities ranging between 92% and 98%) SiC networks. These networks exhibit a unique hierarchical architecture in which thin layers with honeycomb‐like structure and internal strut length in the order of 1–10 ...

Controlling Phase Assemblage in a Complex Multi‐Cation System: Phase‐Pure Room Temperature Multiferroic (1−x)BiTi(1−y)/2FeyMg(1−y)/2O3–xCaTiO3

05.02.2016 | Pranab Mandal, Michael J. Pitcher, Jonathan Alaria, Hongjun Niu, Marco Zanella, John B. Claridge, Matthew J. Rosseinsky, Advanced Functional Materials, 2016

A room temperature magnetoelectric multiferroic is of interest as, e.g., magnetoelectric random access memory. Bulk samples of the perovskite (1−x)BiTi(1−y)/2FeyMg(1−y)/2O3–xCaTiO3 (BTFM–CTO) are simultaneously ferroelectric, weakly ferromagnetic, and magnetoelectric at room temperature. In ...

Room‐Temperature Alkynylation of Phosphine Oxides with Copper Acetylides: Practical Synthesis of Alkynylphosphine Oxides (Eur. J. Org. Chem. 4/2016)

05.02.2016 | Diego A. Alonso, Alejandro Baeza, Rafael Chinchilla, Gabriela Guillena, Isidro M. Pastor, Diego J. Ramón, European Journal of Organic Chemistry, 2016

The cover picture shows the alkynylation of phosphine oxides with copper acetylides. These polymeric, rock‐stable and unreactive reagents can be readily activated by coordination with simple ligands and oxidation with molecular oxygen. This activation enables the in situ generation of highly ...
