“…Promoted zeolites, hydroxyapatites and the metal oxide systems are usually employed as catalytic materials for the reaction, yielding different activities and selectivities. 9 The hydroxyapatite (HAP, Ca 10 (PO 4 ) 6 (OH) 2 ) catalysts are characterized by a unique property comprising of both acid and basic sites in a single structured crystal (52,53). This property enabled their catalytic performance in many processes other than the ETB reaction (54,55).…”

Biobutanol is increasingly attracting industrial interest as fuel additive due to its numerous advantages over bioethanol that include higher calorific value, fuel efficiency and reducedengine problems. Therefore, bioethanol valorization to biobutanol provides a good option for the energy industry. The paper reviewed literature on the recent progress for the ethanol to butanol (ETB) process. Issues related to catalyst development and the role of compositional properties (i.e. catalyst nature and acidity-basicity) and reaction parameters in enhancing butanol yield were critically examined. The mini review also discussed the reaction mechanisms involved and identified new paths for further studies.

We proposed an indium tin oxide (ITO) sensor for detecting NH 3 in seawater and carried out a series of experiments to investigate the feasibility of using it as a hazardous and noxious substance (HNS) sensor. The ITO layer revealed a distinct resistance change, which was linearly correlated with the NH 3 concentration at room temperature. The ITO layer was evaluated using a seawater and ammonium hydroxide (NH 4 OH) solution. The evaluation revealed an almost linear output signal up to an NH 3 concentration of 5%. The sensitivity of the sensor showed a small temperature dependence within a 5-35 °C range. In addition, no significant degradation was observed during a 7-d-long durability test. The aqueous ammonia sensor based on a printed, porous ITO layer has been explained in terms of reduction reaction at the surface and the formation of an electrical double layer (EDL).

“…Previous researches were mainly focused on the qualitative analysis to build response system of HNS spill accidents [3]- [5]. Cunha et al [3] analysed the 119 accidents around the world with the frequency of HNS according to classification standards such as Standard European Behaviour Classification (SEBC) and International Bulk Chemical (IBC) code.…”

Recently, the marine transportation of hazardous and noxious substances (HNS) has increased continuously. This has raised the risk of HNS spill accidents significantly and emphasized the issue of creating an emergency response system that is specialized to HNS. However, various types and properties of HNS have made it difficult to respond to the accidents. To develop the response system for HNS accidents, some qualitative considerations and statistical approaches are required. However, the previous studies have limitations due to the infrequency of accidents and lack of real-case data. The present study was performed with 103 cases of global HNS accidents from online database. In addition, 58 cases were nonlinearly projected using a self-organizing map, after some steps of data handling. Information about the date and year of accidents, location, cause, type of HNS, amount of spill, type of vessels, and the age of vessels was gathered and learned by SOM after the handling process. The learning parameters were optimized by trial-and-error, and the results of clustering showed 6 types of HNS accidents. The weight vectors of neurons in different clusters showed differences ways to classify HNS accidents. The type of vessel is a particular priority in the classification process.
