The current environmental scenario has encouraged the study of renewable and competitive alternative feedstocks for biodiesel production. Microalgae present a significant opportunity as feedstock that does not require arable land can be cultivated using wastewater. paper investigates optimization production from microalgae Nannochloropsis gaditana bio-oil response surface methodology also analyzes main physicochemical properties bio-oil. It was confirmed this is suitable materials with low...
This paper studies the wetting properties of seven phosphonium cation-based ionic liquids: trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl) phosphinate [P66614][(iC8)2PO2], bis(2-ethylhexyl)phosphate [P66614][BEHP], bis(trifluoromethylsulfonyl) imide [P66614][NTf2], tributyltetradecylphosphonium dodecylbenzenesulfonate [P44414][DBS], tributylethylphosphonium diethylphosphate [P4442][DEP], dicyanamide [P66614][DCA], and chloride [P66614][Cl]. The surface tension was analyzed using...
This work studies the performance of three phosphonium-based ionic liquids ([P6,6,6,14][BEHP], [P6,6,6,14][TCM] and [P6,6,6,14][DEC]) when used separately as additives on thermal conductivity, stability tribological properties two non-additised greases (a lithium-based a calcium-based grease). The main results confirmed that improved both greases. Only mixtures G1 + 5%[P6,6,6,14][BEHP] G2 5%[P6,6,6,14][TCM] showed slight increase in conductivity. In general, addition ILs to grease increased...
Abstract Haematococcus pluvialis microalgae have emerged as a prevalent source of antioxidants in cosmetics and nutritional products. Additionally, numerous researchers posited the potential this to produce fatty acid methyl esters (FAME). Nevertheless, optimization production FAME from H. oil has not been investigated. In study, transesterification reaction bio-oil was optimized using response surface methodology, resulting optimal experimental conditions for an methanol ratio 1:4.17, at...
Anthropogenic litter is considered a potential vector for the dispersal of non-indigenous species (NIS) in marine ecosystems. Using bay Gijon (Southwestern Bay Biscay) as case study, we studied composition and transfer communities inhabiting three different environment components: 1) natural artificial substrates from international port Gijon, 2) six proximate rocky beaches 3) floating collected adjacent coast. A total 717 organisms were morphologically identified DNA barcoded using COI 18S...
Early detection of invasive species is crucial to deal effectively with biological invasions in ports, which are hotspots introductions. In this study, a simplified end-time PCR methodology conducted on eDNA from water samples was developed for rapid the seaweed Asparagopsis armata (four hours collection result visualization). It tested dockside four international Spanish ports presence stakeholders, whose feedback obtained explore real applicability biotechnology. Although were not main...
Abstract Non-compliance with or misinterpretation of the International Regulations for Preventing Collisions at Sea (COLREGs) when assessing vessel encounters, and lack good communication between vessels involved in a critical situation, are primary contributing factors collisions. Vessels engaged an encounter should be aware that they part same scenario which can become critical. Sharing contrasting their information about would help those responsible to take manoeuvring decisions...
Introduction The majority of studies on marine biosecurity focus aquatic species, but invaders can also use dry ship compartments for dispersal; this pathway has been less explored than fouling or ballast water. Here we analysed the maritime traffic international Port Gijon (south Bay Biscay, Spain) as a case study. Methods Main donor countries were identified from data. From Global Invasive Species Database, detected similar proportion expected global alien invasive species (AIS) and...
Two phosphonium-derived ionic liquids: trihexyltetradecylphosphonium bis(2-ethylhexyl)phosphate (IL1) and tricyanomethanide (IL2) were used as additives in lithium complex- (G1) anhydrous calcium-based (G2) greases at 5 wt%. Friction torque wear tests performed using a modified four-ball machine for testing rolling bearings order to determine the friction reducing properties of these grease samples real component. The IL2 improved reduction performance both greases, especially G1. Both ILs...
Biodegradable waste is the most significant percentage in overall generation, which has become a challenging environmental problem, as does sewage sludge, requires further treatment before agricultural use.This study aimed to evaluate supplementing effect of two types dry sludge on composting food using barrel.Results showed significance (p<0.05) adding either natural dried (NDS) or polymerinfused (PIDS) achieving thermophilic condition needed for pathogen inactivation.Moreover, addition...
