Abstract
Purpose
This paper proposes to examine a simple and cost‐effective method of integrating a reflector surface with a silicon‐based microfluidic channel for enhanced biosensing through the method of fluorescence in a microfluidics and nanofluidics‐based lab‐on‐a‐chip device.
Design/methodology/approach
Herein, the reflector is integrated with silicon‐based microfluidic channels and fluorescence measurements were carried out using alexafluor 647 particles. Two types of microfluidic channel surfaces were used, with and without reflector integration, for the experiments.
Findings
The experimental results prove that the proposed technique of partial reflector integration within microfluidic or nanofluidic channel surfaces is highly suitable for fluorescence‐based detection of single molecules and low concentration fluorophore‐tagged receptors.
Originality/value
It is believed that this is a novel work of integrating a reflector with a microfluidic channel surface for fluorescence‐based biodetection. This method will be very useful for fluorescence‐based biosensors in detecting low concentration fluorophores and single molecules.

Abstract
Purpose
The academic literature and research lines exploring the effect of quality improvement methods on environmental performance still remain in early stages. The purpose of this paper is therefore to investigate, through a systematic review of the existing academic literature, the environmental (green) impact of using quality and operations improvement methods such as Lean, Six Sigma and Lean Six Sigma. This includes the impact on energy saving and the usage of natural resources.
Design/methodology/approach
This study follows a systematic literature review approach through which it analyses research papers published in top 16 operations and quality management journals. No specific time frame was established, but a set of keywords were used to short-list the articles. A sample of 70 articles was finally short-listed and analysed to provide a discussion on environmental concerns related to Lean, Six Sigma and Lean Six Sigma.
Findings
The comprehensive review of short-listed articles indicates that both Lean and Six Sigma can be considered effective methods to support the conservation of resources, combat global warming and saving energy. Various scholars provide evidence of this, and as such, organisations should not only consider these methods to manage quality and improve operational performance but also meet environmental regulations. A set of research questions that demands further investigation has also been proposed based on the findings of this research.
Research limitations/implications
This study is limited to a sample of 70 articles collected from top 16 operations and quality management journals. The search of journals is also limited to a set of key words (“Lean”, “Green”, “Six Sigma”, “environment”, “sustainable” and “sustainability”) used to short-list the sample size.
Practical implications
The study shows that organisations can consider the adoption of Lean, Six Sigma and Lean Six Sigma to meet environmental regulations, save costs and also meet quality management standards. This will contribute in helping organisations to formulate more effective and inclusive strategies which do not only consider the quality and operational dimensions but also the environmental dimension.
Originality/value
Literature exploring the environmental/green impact of quality management methods commonly used in industry is limited. There is also a lack of studies aiming to investigate the green impact of Lean and Six Sigma in top operations and quality management journals. The study focusing on investigating the green impact of Lean, Six Sigma and Lean Six Sigma methods altogether is also a research first of its kind.

Abstract
Purpose
The purpose of this paper is to demonstrate the rationale and method for studying product adaptation in rural markets.
Design/methodology/approach
The paper takes the form of an exploratory design that includes; review of literature, pilot study, and survey method.
Findings
Findings of the study are contrary to the general understanding that rural is perceived very differently and hence operationalised differently by different organisation. However, results indicate that contingency theory holds true in case of product adaptation in rural markets also. With the increase in executives' representation of rurality, product adaptation degree also increased.
Originality/value
This is probably the first academic study on product adaptation in rural markets to the best of our knowledge. The study attempted to contextualise product adaptation construct from international marketing to rural marketing domain.

Abstract
Purpose
The paper aims to provide a door-to-door holistic perspective on the state of a production system based on several metrics and their relationships, to utilize a combination of tools and techniques and to develop a unique model for production system assessment. The study addresses the limitations of narrow approaches by proposing a new metric as a single indicator of the production system’s overall state.
Design/methodology/approach
The research methodology adopted is design science research. It proposes a framework that combines value stream mapping, simulation and fuzzy logic to study the impact of different lean interventions on the overall state. An offsite construction facility was used as a case study. Data were gathered using methods such as ethnography, interviews, time and motion studies, shopfloor observations, video surveillance and database exploration.
Findings
The paper highlights how some interventions can have local improvements but lead to negative impacts on the overall system state. It emphasizes the importance of having a holistic approach to analyze and improve the true state of a production system.
Research limitations/implications
The study excludes impacts of the supply chain and assumes the system to be confined within the shopfloor. Researchers are encouraged to include those variables in future studies.
Practical implications
The study presents a practical framework and tool that can be tailored to any production system and be used to improve its performance.
Originality/value
This paper proposes a unique framework and a new metric for system state assessment and improvement.

The purpose of this paper is to study the interaction of main marine organisms on localized corrosion of 316L stainless steel in the Dalian Sea area.
Abstract
Purpose
The purpose of this paper is to study the interaction of main marine organisms on localized corrosion of 316L stainless steel in the Dalian Sea area.
Design/methodology/approach
The steel plate was immersed in the Dalian Sea area for nine months to observe the biofouling and localized corrosion. The local potential distribution on the steel plate covered by marine organisms was measured. The local electrochemical measurements were performed to facilitate understanding the interfacial status under different biofouling conditions. The local surface morphologies and corrosion products were characterized.
Findings
The localized corrosion of stainless steel is mainly induced by the attachment of barnacles on the steel. The mussels have no influence on the localized corrosion. The cover of sea squirts could mitigate the localized corrosion induced by barnacles. Both crevice corrosion and pitting corrosion were found beneath the barnacle without the covering of sea squirts. The pitting damage was more serious than the crevice corrosion in the Dalian Sea area. The probing of sulfur element indicates that the potential growth of sulfate-reducing bacteria at barnacle center.
Originality/value
The above findings revealed that the interaction of marine organisms has significant influences on the localized corrosion of stainless steel. The influences of macro-fouling and micro-fouling on localized corrosion are discussed.
