Enhanced Raman scattering from aromatic dithiols electrosprayed into plasmonic nanojunctions
Authors: El-Khoury Patrick Z. , Johnson Grant E. , Novikova Irina V. , Gong Yu , Joly Alan G. , Evans James E. , Zamkov Mikhail , Laskin Julia , Hess Wayne P.
Published: June 2015

We describe surface enhanced Raman spectroscopy (SERS) experiments in which molecular coverage is systematically varied from 3.8 × 105to 3.8 × 102to 0.38 molecules per μm2using electrospray deposition of ethanolic 4,4′-dimercaptostilbene (DMS) solutions. The plasmonic SERS substrate used herein consists of a well-characterized 2-dimensional (2D) array of silver nanospheres (see El-Khouryet al.,J. Chem. Phys., 2014,141, 214308), previously shown to feature uniform topography and plasmonic response, as well as intense SERS activity. When compared to their ensemble averaged analogues, the spatially and temporally averaged spectra of a single molecule exhibit several unique features including: (i) distinct relative intensities of the observable Raman-active vibrational states, (ii) more pronounced SERS backgrounds, and (iii) broader Raman lines indicative of faster vibrational dephasing. The first observation may be understood on the basis of an intuitive physical picture in which the removal of averaging over multiple molecules exposes the tensorial nature of Raman scattering. When an oriented single molecule gives rise to the recorded SERS spectra, the relative orientation of the molecule with respect to vector components of the local electric field determines the relative intensities of the observable vibrational states. Using a single molecule SERS framework, described herein, we derive a unique molecular orientation in which a single DMS molecule is isolated at a nanojunction formed between two silver nanospheres in the 2D array. The DMS molecule is found lying nearly flat with respect to the metal. The derived orientation of a single molecule at a plasmonic nanojunction is consistent with observations (ii) and (iii). In particular, a careful inspection of the temporal spectral variations along the recorded single molecule SERS time sequences reveals that the time-averaged SERS backgrounds arise from individual molecular events, marked by broadened SERS signatures. We assign the broadened spectra along the SERS time sequence – which sum up to a SERS background in the averaged spectra – to instances in which the π-framework of the DMS molecule is parallel to the metal at a classical plasmonic nanojunction. This also accounts for Raman line broadening as a result of fast vibrational dephasing, and driven by molecular reorientation at a plasmonic nanojunction. Furthermore, we report on the molecular orientation dependence of single molecule SERS enhancement factors. We find that in the case of a single DMS molecule isolated at a plasmonic nanojunction, molecular orientation may affect the derived single molecule SERS enhancement factor by up to 5 orders of magnitude. Taking both chemical effects as well as molecular orientation into account, we were able to estimate a single molecule enhancement factor of ∼1010in our measurements.
A framework for the analysis of the security of supply of utilising carbon dioxide as a chemical feedstock
Authors: Fraga Eric S. , Ng Melvin
Published: June 2015

Recent developments in catalysts have enhanced the potential for the utilisation of carbon dioxide as a chemical feedstock. Using the appropriate energy efficient catalyst enables a range of chemical pathways leading to desirable products. In doing so, CO2 provides an economically and environmentally beneficial source of C1 feedstock, while improving the issues relating to security of supply that are associated with fossil-based feedstocks. However, the dependence on catalysts brings other supply chains into consideration, supply chains that may also have security of supply issues. The choice of chemical pathways for specific products will therefore entail an assessment not only of economic factors but also the security of supply issues for the catalysts. This is a multi-criteria decision making problem. In this paper, we present a modified 4A framework based on the framework suggested by the Asian Pacific Energy Research centre for macro-economic applications. The 4A methodology is named after the criteria used to compare alternatives: availability, acceptability, applicability and affordability. We have adapted this framework for the consideration of alternative chemical reaction processes using a micro-economic outlook. Data from a number of sources were collected and used to quantify each of the 4A criteria. A graphical representation of the assessments is used to support the decision maker in comparing alternatives. The framework not only allows for the comparison of processes but also highlights current limitations in the CCU processes. The framework presented can be used by a variety of stakeholders, including regulators, investors, and process industries, with the aim of identifying promising routes within a broader multi-criteria decision making process.

Published: June 2015

The technologies and application of distributed generators (DGs) are progressing rapidly due to the advantages of DGs. The penetration of renewable resources becomes higher and higher, which brings a lot of problems in distribution networks (DNs). The selection of interconnection point for DGs is required to be solved urgently. In this paper, the factors impacting on the interconnection includes host DN structure, DG characteristics, and DG function, which are analysed in order to provide the constraints for the selection strategy. The objective of the selection strategy is to search the interconnection point with the minimum equipment and operation costs. The IEEE 34-node test bed and a practical project of the building integrated photovoltaic in Shanghai are utilized to demonstrate the effectiveness of the selection strategy.

Authors: Kumar Manoj , Yadav Avadhesh
Published: June 2015

In this paper, experiments have been performed in order to determine the design parameters, i.e., air gap height, inclination angle, effective thickness of glass, and effective number of glazing for the water production from atmospheric air by using silica gel as solid desiccant material. Experiments have been performed in the Indian climatic condition at NIT Kurukshetra, India [29° 58′ (latitude) North and 76° 53′ (longitude) East]. A newly designed solar glass desiccant box type system, three in numbers, has been used. It is found that design parameters for the maximum production of water from the atmospheric air are air gap height as 0.22 m, inclination in angle as 30°, effective thickness of glass as 3 mm, and number of glazing as single.
Advance care planning in 21st century Australia: a systematic review and appraisal of online advance care directive templates against national framework criteria
Authors: Luckett Tim , Bhattarai Priyanka , Phillips Jane , Agar Meera , Currow David , Krastev Yordanka , Davidson Patricia M.
Published: June 2015

Objectives
A drive to promote advance care planning at a population level has led to a proliferation of online advance care directive (ACD) templates but little information to guide consumer choice. The current study aimed to appraise the quality of online ACD templates promoted for use in Australia.

Methods
A systematic review of online Australian ACD templates was conducted in February 2014. ACD templates were identified via Google searches, and quality was independently appraised by two reviewers against criteria from the 2011 report A National Framework for Advance Care Directives. Bias either towards or against future medical treatment was assessed using criteria designed to limit subjectivity.

Results
Fourteen online ACD templates were included, all of which were available only in English. Templates developed by Southern Cross University best met the framework criteria. One ACD template was found to be biased against medical treatment – the Dying with Dignity Victoria Advance Healthcare Directive.

Conclusions
More research is needed to understand how online resources can optimally elicit and record consumers’ individual preferences for future care. Future iterations of the framework should address online availability and provide a simple rating system to inform choice and drive quality improvement.

What is known about the topic?
Online availability of ACD templates provides consumers with an opportunity for advance care planning outside of formal healthcare settings. While online availability has advantages, there is a risk that templates may be biased either for or against medical treatment and may not elicit directives that are appropriately informed by reflection on personal values and discussion with family and health professionals.

What does this paper add?
This is the first attempt at monitoring the quality and bias of online ACD templates designed for use in Australia.

What are the implications for practitioners?
The results of this review provide a description and quality index to assist consumers and clinicians in deciding which online ACD template to use or recommend.
Growth targets and rearing strategies for replacement heifers in pasture-based systems: a review

Published: June 2015

Dairy heifer growth and liveweight at first calving are regarded as important management variables affecting profitability and animal welfare. However, the appropriateness of heifer growth rate targets for different farming systems is not clear. Retrospective assessments of the association between heifer liveweight and subsequent productivity indicate significant benefits in milk production and, even, reproduction from increasing liveweight at breeding and first calving. However, prospective interventionist experiments do not concur, with very variable effects of liveweight at breeding on milk production and with only limited evidence of a positive effect of first-calving liveweight on first-lactation milk yield. In addition, any benefit in the first lactation is not evident in subsequent lactations in the limited number of long-term studies reported. Pre-weaning nutrition and average daily weight gain are areas of increasing interest, with lifelong increases in milk production resulting from accelerated growth rates during the first 8 weeks of life, indicating a possible significant return from a short-term investment. This could be one reason for the inconsistent effects of heifer liveweight at breeding and first lactation on milk production. Although the effect of pre-weaning average daily gain on heifer liveweight is short-lived, a recent meta-analysis indicated that pre-weaning average daily gain explains 22% of the variation in first-lactation milk production. Whether these differences in animal physiology have relevance in grazing systems, wherein heifers and cows do not consume sufficient nutrients to reach their potential, requires investigation. Despite considerable extension efforts over successive decades, current evidence indicates that failure to provide the new-born calf with sufficient high-quality colostrum is common. To understand the reasons for suboptimal colostrum feeding requires social research, with appropriate extension strategies developed to elicit practice change. Although there can be little doubt regarding the importance of heifer rearing to the profitability and sustainability of the farming business, the collective literature points to a failure of retrospective analyses in determining the cause of poor heifer performance. In reality, it is likely to be a combination of factors. The objective of this review is to investigate the effect of liveweight gain at various stages of the growth cycle of the heifer on the milk-production capacity of the lactating animal.

Hume and the nominalist tradition
Authors: Brown Deborah
Published: June 2015

Many of the central theses of Hume's philosophy – his rejection of real relations, universals, abstract objects and necessary causal relations – had precedents in the later medieval nominalist tradition. Hume and his medieval predecessors developed complex semantic theories to show both how ontologies are apt to become inflated and how, if we understand carefully the processes by which meaning is generated, we can achieve greater ontological parsimony. Tracing a trajectory from those medieval traditions to Hume reveals Hume to be more radical, particularly in his rejection of abstraction and abstract ideas. Hume's denial of general, abstract ideas is consistent with his philosophical principles but fails to appreciate the more sophisticated nominalist approaches to abstraction, the result of which is a theoretically impoverished account of our capacity for generalization.
