For many decades, silicone elastomers with oil incorporated have served as fouling-release coating for marine applications. In a comprehensive study involving series of laboratory-based fouling assays and extensive global field studies up to 2-year duration, we compare polydimethylsiloxane (PDMS) coatings the same composition loaded via two different methods. One method used traditional, one-pot pre-cure addition approach (o-PDMS) another newer post-cure infusion (i-PDMS). The latter...
The increasing trend of LEDs die size reduction driven by the demand for high-resolution displays and compact wearable devices, presents significant challenges assembly packaging. Achieving sufficient paste volume maintaining low void rate in solder during mounting on substrate process is crucial high performance LED applications. This paper a novel approach to wafer bumping using printing process. It demonstrates methods used achieve good with via three reflow steps different stencil...
The American brackish-water mussel Mytella strigata is reported from Singapore for the first time. In 2016 a survey of intertidal hard structures in Johor Straits revealed its almost ubiquitous presence high mean densities, up to 124 ± 32 individuals 25 cm−2 along shoreline. Subtidal nets employed by floating fish farms were also fouled with this species. Densities exceeding 10,000 100 observed, exclusion relative Perna viridis, Asian green mussel. Size-frequency analyses shells indicated...
Aluminum and zinc based sacrificial anodes are routinely used to provide corrosion protection metals (typically steel) exposed seawater, for example in steel pipelines storage tanks. However, the high fouling rates experienced South East Asia means that both be protected rapidly become coated with macrofoulers, which could potentially prevent from being effective. The present study, involving exposure tests of up 18 months, indicates aluminum remain effective even after completely...
The economic, social and environmental impacts arising from the transfer establishment of non indigenous marine species (NIMS) mediated through ship hull biofouling ballast water discharges in coastal environment require a regional approach to manage bio-invasions. As coordinating body for maritime shipping affairs protection environment, International Maritime Organization (IMO) has been working with member states adopt ratify global conventions aimed at preventing invasive shipping. major...
In recent years, there has been much attention on the effects of lubricant additives friction and wear properties surface coatings. However, little research conducted to investigate influence antiwear tribological performances titanium nitride (Ti–N) aluminium (Ti–Al–N) It reported that introducing into Ti–N coatings enhanced their oxidation resistance. this study utilising a pin cylinder tribometer, lubricants containing zinc dialkyl dithiophosphate (ZDDP) or more environmentally friendly...
The South American charru mussel, Mytella strigata, was recently recorded in Singapore waters, possibly introduced into Southeast Asia through shipping. mussels have rapidly spread across estuarine coastal mudflats. Adult were collected, spawned aquaria and larvae successfully cultured to the juvenile stage laboratory. larval morphology development of M. strigata is described this paper. D-shaped veligers produced within 20 h fertilization approximately 75 µm shell length. These capable...
Rapid and species-specific detection, quantification of pathogenic bacteria are fundamental for monitoring assessment the risk they pose to any ecosystem. The study employed Vibrio cholerae, a human pathogen responsible life-threatening diarrhoeal disease, cholera one among most unwanted from marine bioinvasion point view. present coupled fluorescence in situ hybridization (FISH) technique, powerful tool molecular phylogenetic discrimination, with flow cytometry (FCM), technique used rapid...
In recent years, there has been significant attention paid to the effect of lubricant additives on tribological properties advanced surface coatings. However, not many research papers have addressed influence performance chromium nitride (Cr–N) this study, lubricants containing zinc dialkyl dithiophosphate (ZDDP) or triphenyl phosphorothionate (TPPT) were used conduct tests based a disc cylinder tribometer. The wear scars formed Cr–N coated discs analysed using sensitive analytical...
In this present work, we have successfully synthesized vertical aligned ZnO nanorod arrays (ZnO NRs) on conductive stainless-steel substrate. These NRs were obtained by using a low temperature, cost, and eco-friendly hydrothermal approach. The effect of the sol-gel deposited seed layer alignment has been thoroughly studied. Characterizations as-obtained nanorods investigated scanning electron microscopy (SEM), X-ray diffraction (XRD), atomic force (AFM), high-resolution transmission...
Limited knowledge of native marine biodiversity hinders effective management to safeguard South and Southeast Asia’s coastal environment against the threat invasive species transfer through shipping. In particular, sessile biofouling organisms in East Asian ports are poorly known. Through support ASEAN-India Cooperation Project on Extent Transfer Alien Invasive Organisms South/South Asia Region by Shipping, a coordinated effort examine diversity major port areas India was made using...
Surface waters are threatened by pollutants of atmospheric origin. Atmospheric deposition in Singapore and surrounding countries appears to provide significant fluxes nutrients (Nitrogen species Phosphorous species) environmental concern play an important role the eutrophication surface water. The quantitative assessment nutrient depositions essential for understanding regional variations, time at which critical loads exceed, air/water quality management on scale. This paper presents a...
Horseshoe crabs may act as mobile substrata for communities of sessile marine organisms on intertidal mudflats. In Singapore, the mangrove horseshoe crabs, Carcinoscorpius rotundicauda (Latreille, 1802) were surveyed diversity epibiotic macrofauna. The most common epibiota observed was barnacles belonging to Amphibalanus spp., along with other organisms: slipper snails Crepidula walshi and anemones (species undetermined). We also report first account an invasive American brackish mussel,...
Incinerated sewage sludge ash is tested here as a cement and aggregate substitute in mortar blocks where it can be used at various percentages replacement to reduce the overall cost promote recycling. The compressive strength of cast was 28 days determine best formulation with optimal combination ball milled (replacing cement) sand) along control block (made & sand only). were for their flexural other properties including surface functional groups, constituent phases porosity, mortars...
