Recovery of Flavonoids from Walnuts De‐Pellicle Wastewater with Macroporous Resins and Evaluation of Antioxidant Activities In Vitro

27.08.2015 | Yaxin Zhu, Hao Song, Xu Zhang, Chaoyin Chen, Shenglan Zhao, Feng Ge, Diqiu Liu, Journal of Food Process Engineering, 2015

Abstract Walnut de‐pellicle wastewater is rich in polyphenols and flavonoids that are significant to resource and environment. Enrichment and purification of flavonoids from walnut de‐pellicle wastewater were investigated by five macroporous resins. As static tests shown, AB‐8 resin was the ...

Nonaqueous Redox-Flow Batteries: Organic Solvents, Supporting Electrolytes, and Redox Pairs

26.08.2015 | Ke Gong; Qianrong Fang; Shuang Gu; S F Y Li; Yushan Yan, Energy & Environmental Science, 2015

As a family member of redox-flow batteries (RFBs), nonaqueous RFBs can offer wide working temperature, high cell voltage, and potentially high energy density. These key features make nonaqueous RFBs an important complement of aqueous RFBs, broadening the spectrum of RFB applications. The ...

Shedding of Water Drops from a Surface under Icing Conditions

19.08.2015 | Deepak Kumar Mandal; Antonio Criscione; C. Tropea; A. Amirfazli, Langmuir, 2015

A sessile water drop exposed to an air flow will shed if the adhesion is overcome by the external aerodynamic forces on the drop. In this study, shedding of water drops were investigated under icing conditions, on surfaces with different wettabilities, from hydrophilic to superhydrophobic. A wind ...

Low-Temperature Plasma Ionization Differential Ion Mobility Spectrometry

19.08.2015 | Andriy Kuklya; Carsten Engelhard; Florian Uteschil; Klaus Kerpen; Robert Marks; Ursula Telgheder, Analytical Chemistry, 2015

A low-temperature plasma (LTP) was used as an ionization source for differential ion mobility spectrometry (DMS) for the first time. This ionization source enhances the potential of DMS as a miniaturized system for on-site rapid monitoring. The effects of experimental parameters (e.g., ...

Conformational Analysis of Large and Highly Disulfide-Stabilized Proteins by Integrating Online Electrochemical Reduction into an Optimized H/D Exchange Mass Spectrometry Workflow

18.08.2015 | Esben Trabjerg; Rasmus U. Jakobsen; Simon Mysling; Søren Christensen; Thomas J. D. Jørgensen; Kasper D. Rand, Analytical Chemistry, 2015

Analysis of disulfide-bonded proteins by hydrogen/deuterium exchange mass spectrometry (HDX-MS) requires effective and rapid reduction of disulfide bonds before enzymatic digestion in order to increase sequence coverage. In a conventional HDX-MS workflow, disulfide bonds are reduced chemically by ...

Rheology of Imidazolium-Based Ionic Liquids with Aromatic Functionality

18.08.2015 | Ran Tao; Sindee L. Simon, Journal of Physical Chemistry B, 2015

A series of imidazolium-based ionic liquids with cyclic and aromatic groups and a bis[(trifluoromethane)sulfonyl]amide anion were characterized using dynamic and steady shear rheology in a wide temperature range. The cations investigated include 1-(cyclohexylmethyl)-3-methylimidazolium ...

Effect of Annealing Temperature and Oxygen Flow in the Properties of Ion Beam Sputtered SnO2— x Thin Films

14.08.2015 | Wang, Chun-Min ; Huang, Chun-Chieh ; Kuo, Jui-Chao ; Sahu, Dipti Ranjan; Huang, Jow-Lay, Materials, 2015

Tin oxide (SnO2 —x) thin films were prepared under various flow ratios of O2/(O2 + Ar) on unheated glass substrate using the ion beam sputtering (IBS) deposition technique. This work studied the effects of the flow ratio of O2/(O2 + Ar), chamber pressures and post-annealing treatment on the ...

IJMS, Vol. 16, Pages 19291-19307: Tangential Flow Ultrafiltration Allows Purification and Concentration of Lauric Acid-/Albumin-Coated Particles for Improved Magnetic Treatment

14.08.2015 | Zaloga, Jan ; Stapf, Marcus ; Nowak, Johannes ; Pöttler, Marina ; Friedrich, Ralf P.; Tietze, Rainer ; Lyer, Stefan ..., International Journal of Molecular Sciences, 2015

Superparamagnetic iron oxide nanoparticles (SPIONs) are frequently used for drug targeting, hyperthermia and other biomedical purposes. Recently, we have reported the synthesis of lauric acid-/albumin-coated iron oxide nanoparticles SEONLA-BSA, which were synthesized using excess albumin. For ...

Molecular Simulations of Fatty‐Acid Methyl Esters and Representative Biodiesel Mixtures

13.08.2015 | Vivek S. Bharadwaj, Nathaniel M. Eagan, Nicholas M. Wang, Matthew W. Liberatore, C. Mark Maupin, ChemPhysChem, 2015

Abstract Despite the importance of fatty‐acid methyl esters (FAMEs) as key components of various green solvents, detergents, plasticizers, and biodiesels, our understanding of these systems at the molecular level is limited. An enhanced molecular‐level perspective of FAMEs will enable a ...

The Effects of Two Forms of Ice on Microbiological and Physiochemical Properties of Barramundi (Lates Calcarifer, Bloch) Fillets

13.08.2015 | Sona Younus Zakhariya, Ravi Fotedar, David Prangnell, Journal of Food Processing and Preservation, 2015

Abstract Barramundi (Lates calcarifer) fillets were subjected to two different ice forms (pre‐freezing treatments: slurry ice [SI] and flake ice [FI]) for 0 (before freezing) and 1 h and 1, 2, 4, 8 and 16 days prior to blast freezing at −80C for 8 h. Fillets were then stored in a freezer at ...
