This paper aims to synthesize silver nanoparticles using atmospheric discharge plasma in contact with liquid at different pressure in reactor and to assess their catalytical properties for reducing 4-nanoparticles (NP).

The Ag colloidal NPs was rapidly synthesized as a result of non-equilibrium low-temperature plasma formation between an electrode and the surface of AgNO₃ solution for 5 min at different pressure in reactor. Synthesized Ag NPs were characterized with common analytical techniques. Ultraviolet–visible (UV) spectroscopy, dynamic light scattering, scanning microcopy analysis were used to study the formation and characteristics of silver nanoparticles.

The formation of silver colloidal solutions under plasma discharge at different pressure in reactor is characterized by the presence of surface resonance peak in the spectra. Scanning electron microscope (SEM) images confirmed the formation of spherical particles having a size distribution in the range of 15-26 nm. The AgNPs solution showed excellent rapid catalytic activity for the complete degradation of toxic 4-nitrophenol (4-NPh) into non-toxic 4-aminophenol (4-APh) within 18 min.

Further studies are necessary for confirmation of the practical application, especially of deposition Ag NPs on TiO₂.

The method provides a simple and practical solution to improving the synthesis of colloidal solutions of Ag NPs for degradation of organic pollutants (4-NPh) in water and wasters water.

Atmospheric discharge plasma in contact with liquid at different pressure can be used as an effective technique for synthesis of nanomaterials with catalytic properties.

China's Government in 2015 announced its goal of stabilizing the use of fertilizers and pesticide by the year 2020. However, implementation of effective policies is not straightforward, while one may even argue that the policy goal is by far not ambitious enough. Hence, it is useful to look at experiences of other countries that have gone through a similar process. In this paper, the authors explicitly consider the case of European Union's (EU’s) policies aimed at greening agriculture. The choice for the EU is motivated by the fact that the EU is about 35 years ahead of China in implementing a policy agenda to counter the problems China is facing now.

In this paper, the authors focus on agricultural inputs, in particular fertilizer and pesticides, as well as land use and their impact on food safety, air and water quality, soil degradation, greenhouse gas (GHG) emissions and biodiversity. Policies related to those issues are discussed for both, China and the EU. Given that implementation and monitoring are critical for the success of policies, the authors also discuss how policies are implemented and monitored under different governance and institutional conditions.

From the EU experiences, positive and negative, three central lessons are drawn: (1) China should strive for cross compliance but in two steps. In the first step, arrangements for on-farm monitoring must be made, coupled with a pilot program of cross-compliance conditions for large farms in selected counties; in the second step, cross-compliance requirements must be introduced for all farmers, with additional funds for rural development in vulnerable areas. (2) Strong stakeholder commitment should be sought in the formulation as well as implementation of greening policies. (3) Monitoring of greening results should be harmonized and standardized across the country, with a limited number of indicators.

This paper contributes to the policy discussion by comparing the agricultural greening measures in the EU (which was some 35 years ago in the same situation as China now) with the measures taken in China so far.

Social marketing theories have habituated to a theoretical and methodological focus that is criticised for being myopic and stigmatising. Following recommendations to redirect focus theoretically, the purpose of this paper is to apply an observational methodology to understanding how project stakeholders interact to examine whether consideration of stakeholders can identify factors facilitating or impeding farming practice change.

More than 48 events involving as many as 150 people including project stakeholder meetings, one-on-one consultations and annual events were observed over more than 100 h by between one and five researchers. Field notes were gathered, and thematic coding focussed on understanding how stakeholders facilitated or impeded practice change.

Observations identified limited provision of information about the project by on ground project stakeholders to targeted individuals (farmers). On the rare occasions where information sharing was observed, communication was delayed making it difficult for individuals to connect actions with outcomes observed. Participating stakeholders did not freely support delivery of activities needed for individual practice change.

This study indicates the value of wider process and outcome assessment encompassing stakeholders to identify factors impeding and facilitating farming practice change.

Approaches that centre attention on individuals fail to acknowledge the inputs, activities and outputs delivered by project stakeholders within a system of change. By redirecting evaluation focus, shared responsibility is gained and stigmatisation of one stakeholder group can be avoided.

This study demonstrates how observations can be used to redirect focus to consider actions and interactions occurring between on ground project stakeholders. A stakeholder evaluation approach extends monitoring and evaluation focus beyond individuals targeted for behaviour change. Implications, limitations and future research directions are outlined.

The purpose of this paper is to present an exhaustive review of research studies and activities in the inkjet printing of conductive materials.

This paper gives a detailed literature survey of research carried out in inkjet printing of conductive materials.

This article explains the inkjet printing process and the various types of conductive inks. It then examines the various factors that affect the quality of inkjet printed interconnects such as printing parameters, materials and substrate treatments. Methods of characterising both the inkjet printing process and the electrical properties of printed conductive materials are also presented. Finally relevant applications of this technology are described.

Inkjet printing is currently one of the cheapest direct write techniques for manufacturing. The use of this technique in electronic manufacturing, where interconnects and other conductive features are required is an area of increasing relevance to the fields of electronics manufacturing, packaging and assembly. This review paper would therefore be of great value and interest to this community.

Previous work on employee-driven innovation (EDI) has demonstrated the benefits of employees’ proactive behavior in achieving success with innovations. The purpose of this paper is to employ the concept of personal initiative to investigate the underestimated role of employees’ agency in complex processes of innovation, showing the impact of personal initiative on employees’ innovation success.

Based on two embedded cases of environmental bottom-up innovation at a large manufacturing company, this study examines employees’ behavior in generating, championing and realizing such initiatives.

This paper provides insights into how employees succeeded, through taking initiative in generating, championing and realizing environmental initiatives despite facing high complexity, and resource constraints. Without being prompted from the top down, employees started these initiatives themselves and showed phase-specific behavior in overcoming the various challenges. Thus, self-starting behavior was found dominant in generating ideas, whereas proactive and persistent forms of behavior were found to be prevalent in championing and rolling out the initiatives.

Current understandings of EDI highlight the importance of developing employees’ potential capabilities and organizational-level guidance. Using an active performance perspective, this study emphasizes the importance of employees’ agency in ensuring EDI success, even when conditions are not conducive to their doing so.

The purpose of the present research is to examine the comparative values that urban Vietnamese consumers place on attributes of rice that is produced using environmentally friendly methods. The authors consider the impacts that this may have on the livelihoods of rural Vietnamese small farmers. Rice is an “impure public good” that includes both “private” and “public” attributes that consumers consider in their purchase decisions. Consumers make tradeoffs between environmentally and socially beneficial practices (public goods) and perceptions of product quality (private goods). The authors used latent class modeling to investigate the values associated with attributes of rice that is produced using sustainable farming practices.

The authors used a discrete choice experimental design in which consumers stated their choices among combinations of rice attributes. The survey provided responses from 360 urban Vietnamese consumers and allowed to estimate the preferences and nonpecuniary values for rice grown using different levels of environmentally beneficial production methods.

The results identify two segments of rice consumers: one group of consumers who are sensitive to price and the other group who are sensitive to environmental issues. The individual characteristics are reflected in the choices of production methods and in the willingness to pay for environmentally beneficial outcomes of those methods.

Given the number of independent variables measured, the sample was relatively small, such that confirmatory statistical methods were inconclusive. However, the authors used multiple analytical tools that provide corroboration of the significant determinants of the utility functions for the two segments.

The results provide directions for production of rice at a national level, as well as practical implications for consumer-oriented communications.

Results suggest that the emerging middle class of Vietnamese consumers are willing to pay more for rice that is produced using methods that are beneficial to the environment. Results also indicate challenges to provide sustainably-produced rice to poorer groups of consumers.

The study provides important context for consumer preferences within emerging economies. This also adds to a growing literature that uses the choice experiment method to estimate consumer valuation of the outcomes of various agricultural practices.

The purpose of this work is to study tribological properties of liquid paraffin with SiO₂ nanoparticles as an additive, which are made by surface-modification method. Taguchi robust designs for optimization in synthesizing SiO₂ nanoparticles by sol-gel method.

The tribological properties of the SiO₂ nanoparticles as additive in liquid paraffin are studied by ball-on-ring wear tester to find out optimal concentration, and the mechanism of the reduction of wear and friction will be investigated by scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and atomic force microscope (AFM).

Under optimal conditions identified by Taguchi robust designs method, SiO₂ nanoparticles with a narrow particle size distribution can be obtained and optimal concentrations of SiO₂ nanoparticles as additives in liquid paraffin have better properties than the pure paraffin oil.

It is shown in the paper that by reducing friction and AW, the lubricant prepared by the methods described can prolong operating hours of machinery.

The purpose of this study is to investigate what sustainability initiatives are being implemented by Canadian independent restaurants and to determine if the initiatives represent all 10 categories of a sustainable restaurant as established by a sustainability initiative framework.

The study uses a qualitative approach of semi-structured interviews with 15 small to medium enterprise (SME), independent restaurant owners and operators across Canada. The data was digitally transcribed and thematic analysis was performed.

Results indicated that most initiatives aligned with the categories of “sustainable food/menu” and “waste reduction and disposables” which shows that the operators were inclined to pursue initiatives in customer view. Restaurants put limited focus on water supply, chemicals and pollution reduction, furniture and construction materials. Some of the barriers to implementing, measuring and learning about initiatives were: cost, lack of access to programs, supply chain complications, not having buy-in from owners and lack of time to implement.

The study recommends that governments provide incentives to implement sustainability initiatives that are out of sight to the customer. For example, implementing composting, energy efficient equipment and water saving processes. It is also recommended that third-party restaurant organizations provide more accurate, evidence-based guidance and education on implementing a wide-range of sustainability initiatives.

This research contributes to the literature on sustainability in restaurants and applies a sustainability initiative framework in a practical context. The study provides a unique assessment of the current state of restaurant sustainability and states where restaurants need to improve their efforts.

The application of indigo dyes in the denim industries has been criticised due to the introduction of non-renewable oxidation products into the environment. Previous studies have investigated that reducing sugars can be used as green alternatives to sodium dithionite in the indigo dyeing of cotton fabric owing to their reduced and stable redox potential in the dye bath. The purpose of this study was to dye denim cotton fabric with indigo dye using various reducing sugars and alkalis. The use of sucrose and potassium hydroxide (KOH) for indigo dyeing has been explored for the first time.

A mixed factorial design with four variables including alkali, pH, number of dips and type of reducing sugar at different levels was studied to identify a significant correlation between the effect of these variables on the colour strength and fastness properties of the dyeings.

Investigations were made to examine the significant factors and interactions of the selected responses in the eco-friendly dyeing method. This process has the potential to reduce the load of sulphite and sulphate generated in the dyebath due to the use of a conventional reducing agent, sodium dithionite. The colour strength of the dyeing reduced with fructose was found to be better than other reducing sugars and significantly influenced by the number of dips, pH levels and the interaction between pH and reducing sugars. Using fructose for indigo dyeing with two dips at a pH of 11.5, using KOH as an alkali, results in higher colour strength values. The fastness properties of the indigo-dyed sample with reducing sugars ranging from fair to good or good to excellent. Specifically, colour change receives a rating of grey scale 3–4, staining 4–5, dry rubbing 4 and light fastness 3–4. These assessments hold true across various factors such as the type of reducing sugar, alkali, pH and the number of dips. The optimised parameters leading to improved colour strength and fastness properties are also discussed.

This dyeing technique is novel and a green alternative to dithionite denim dyeing. This process is found to be useful for indigo dyeing of denim fabric leading to reduced and stable redox potential in the dyebath and acceptable colour strength of the dyed fabric.

The purpose of this paper is to benchmark current adoption of green chemistry (GC) practices by the innovative and generic pharmaceutical companies and examine the drivers, barriers and future opportunities.

The authors examined publicly available data for the top 10 “big pharma” and top ten generic drug manufacturers. Using the IQ Green Chemistry working group framework for effective GC programs, they scored each of the 20 companies in seven key areas.

The study finds that generic drug companies have not embraced GC at the level of the innovative pharmaceutical companies (average GC score of 2 vs 11 for “big pharma”). Top two barriers for them include: lack of pressure and incentives, and the burdensome regulatory process for making changes in the manufacturing process.

The research is based on publicly disclosed information. It is possible that some generic drug manufacturers have begun to work internally on GC but have not disclosed externally yet. Future research should include a survey or interviews of generic drug manufacturers.

The company-level analysis, benchmarking framework and results are of value for researchers and practitioners interested in advancing greater adoption of GC by the pharmaceutical industry.

This study provides the first company-level benchmarking of GC adoption by the largest innovative and generics drug manufacturers. It contributes to the literature on the barriers and drivers for greater adoption of GC.
