Surface Plasmon Resonance Photonic Crystal Fiber Biosensor: A Practical Sensing Approach

Abstract: We propose a simple, two rings, hexagonal lattice photonic crystal fiber biosensor using surface plasmon resonance phenomenon. An active plasmonic gold layer and the analyte (sample) are placed outside the fiber structure instead of inside the air-holes, which will result in a simpler and straight forward fabrication process. The proposed sensor exhibits birefringent behavior that enhances its sensitivity. Numerical investigation of the guiding properties and sensing performance are conducted by finite element method. Using wavelength and amplitude interrogation methods, the proposed sensor could provide maximum sensitivity of 4000 nm/RIU and 320 RIU $^{-1}$ , respectively. The resolutions of the sensor are $2.5 \times 10^{-5}$ and $3.125 \times 10^{-5}$ RIU for wavelength and amplitude interrogation modes. The proposed sensor design shows promising results that could be used in biological and biochemical analytes detection.

An investigation of the status of the Malaysian construction industry

Abstract: Purpose – The purpose of this paper is to understand the production processes utilized by the Malaysian construction industry (MCI).Design/methodology/approach – The paper follows an earlier work published in this journal in which the authors analyze the global construction industry focusing on the evolution of lean production systems.Findings – The future of construction is exciting. International markets, innovations in technology, and techniques of construction project management, new relationships across disciplines are all avenues of development. To make the best use of their opportunities, the MCI must invest in research and development (R&D), undertake public education about the field and develop new methodologies to improve operational performance in construction.Originality/value – This paper provides a detailed analysis of the MCI, it's impact on the economy, key success factors, struggles and problems that the industry currently faces. Analysis of key functional areas like operations management...
