A reliable approach to prepare brittle semiconducting materials for cross‐sectional transmission electron microscopy

07-Jul-2017 | J. H. DYCUS, J. M. LEBEAU, Journal of Microscopy, 2017

Summary Here, we present a sample preparation approach that simplifies the thinning of very brittle wide bandgap semiconducting materials in cross‐section geometry for (scanning) transmission electron microscopy. Using AlN thin films grown on sapphire and AlN substrates as case studies, we ...

Molecules, Vol. 22, Pages 1031: Use of Chitosan-PVA Hydrogels with Copper Nanoparticles to Improve the Growth of Grafted Watermelon

22-Jun-2017 | González Gómez, Homero ; Ramírez Godina, Francisca ; Ortega Ortiz, Hortensia ; Benavides Mendoza, Adalberto ; Robled ..., Molecules, 2017

Modern agriculture requires alternative practices that improve crop growth without negatively affecting the environment, as resources such as water and arable land grow scarcer while the human population continues to increase. Grafting is a cultivation technique that allows the plant to be more ...

How Much Will It Cost To Monitor Microbial Drinking Water Quality in Sub-Saharan Africa?

12-May-2017 | Caroline Delaire; Rachel Peletz; Emily Kumpel; Joyce Kisiangani; Robert Bain; Ranjiv Khush, Environmental Science & Technology, 2017

Microbial water quality monitoring is crucial for managing water resources and protecting public health. However, institutional testing activities in sub-Saharan Africa are currently limited. Because the economics of water quality testing are poorly understood, the extent to which cost may be a ...

Simple Means for Fractionating Protein Based on Isoelectric Point without Ampholyte

08-Sep-2016 | Huang Chen; Zaifang Zhu; Haiqing Yu; Joann Juan Lu; Shaorong Liu, Analytical Chemistry, 2016

In this paper, we develop a simple electrokinetic means for fractionating protein samples according to their pI values without using ampholytes. The method uses inexpensive equipment, and its consumables are primarily ammonium acetate buffers. A key component of its apparatus is a dialysis ...

Thermal Independent Modulator for Comprehensive Two-Dimensional Gas Chromatography

25-Aug-2016 | Jim Luong; Xiaosheng Guan; Shifen Xu; Ronda Gras; Robert A. Shellie, Analytical Chemistry, 2016

We introduce a modulation strategy for comprehensive two-dimensional gas chromatography (GC×GC) with complete thermal independence between the cooling and heating stages and without the need for GC oven heat for remobilization. Based on this approach, a compact thermal independent modulator (TiM) ...

Economic benefits of membrane chromatography versus packed bed column purification of therapeutic proteins expressed in microbial and mammalian hosts

03-Aug-2016 | S. Muthukumar, T. Muralikrishnan, R. Mendhe, A.S. Rathore, Journal of Chemical Technology & Biotechnology, 2016

Abstract Background Membrane chromatography has been accepted as the polishing step in several commercial processes for production of monoclonal antibody therapeutics over the past decade. This study aims to compare the performance of the traditional column chromatography with membrane ...

Rapid identification of seized controlled substances and related compounds by tandem mass spectrometry without chromatography

01-Mar-2016 | Carl M. Fletcher, Richard Sleeman, Rapid Communications in Mass Spectrometry, 2016

Rationale This study demonstrates the capability of using tandem mass spectrometry (MS/MS) for the identification of substances of abuse and related compounds without the need for chromatography. The elimination of chromatography is not only cost‐effective because of reduced sample work‐up and ...

Out of Pocket Expenditure for Hospitalization among Below Poverty Line Households in District Solan, Himachal Pradesh, India, 2013

19-Feb-2016 | Anadi Gupt et al., PLoS ONE, 2016

by Anadi Gupt, Prabhdeep Kaur, P. Kamraj, B. N. Murthy Introduction Health insurance schemes, like Rashtriya Swasthya Bima Yojana (RSBY), should provide financial protection against catastrophic health costs by reducing out of pocket expenditure (OOPE) for hospitalizations. We estimated and ...

All‐Iron Redox Flow Battery Tailored for Off‐Grid Portable Applications

20-Nov-2015 | Michael C. Tucker, Adam Phillips, Adam Z. Weber, ChemSusChem, 2015

Abstract An all‐iron redox flow battery is proposed and developed for end users without access to an electricity grid. The concept is a low‐cost battery which the user assembles, discharges, and then disposes of the active materials. The design goals are: (1) minimize upfront cost, ...
