Nannochloropsis sp. is a marine microalgae which contains high valued bio-compounds. However, it contains elevated moisture which hinders extraction of important significant bio-compounds. A dewatering process of Nannochloropsis sp via forward osmosis is proposed. The objective of the study is to evaluate the effect of salinity on the lipid membrane of microalgae Nannochloropsis sp by inducing osmotic pressure difference. A microalgae lipid membrane model was developed using molecular dynamics and evaluated through relative structural changes and water dynamics by varying the salinity. The results revealed at elevated salinity, compression occurs to the lipid membrane based on the tail order and area per head groups. The dynamics of water molecules showed that water migration happens as early as 20 ns. Despite membrane compression, a total of 5 water molecules migrated within the 150 ns. This suggests that forward osmosis is a promising alternative for microalgal dewatering.","PeriodicalId":376919,"journal":{"name":"EnergyRN: Electrochemical Energy Engineering (EnergyRN) (Topic)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130387932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we simulated coherency loss process during the early growth of a Cr precipitate (bcc) in a Cu matrix (fcc) by the combination of Monte Carlo and molecular dynamics. The simulation results reveal the fine details in the evolution of the crystallographic features, including the orientation relationship (OR) between two phases, the precipitate morphology, and interfacial dislocation structure at the early stage of the precipitate growth. Generation of a dominant set of dislocations is the governing event during the evolution process. The selection of the dominant dislocations was rationalized based on the minimization of interfacial energy in the major facet containing a single set of these dislocations. The initial OR developed between the coherent precipitate and the matrix is near the Nishiyama-Wassermann OR, and it changes discretely in response to the early generation of the dominant dislocations, towards the ideal OR corresponding to the O-line condition, near the Kurdjumov-Sachs OR. This tendency reflects the experimental observations in a Cu-Cr system, and provides helpful insight into the evolution of crystallographic features in physical reality.","PeriodicalId":376919,"journal":{"name":"EnergyRN: Electrochemical Energy Engineering (EnergyRN) (Topic)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129993801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is stronger polarization as a result of increased concentration of reduced clusters and thinning of graphene sheets in ERGO papers, first ever electrochemically reduced paper from GO. In GO, there is a greater dependence on frequency due to a higher percentage of interlayer O–H bonds. Dielectric permittivity increases with decreasing frequency due to stronger polarization and reduced conduction losses. At very high frequencies, greater conduction losses are responsible for lower values of dielectric permittivity of ERGO papers compared to GO papers. The “U” or “W” profile (σ vs T curves) of temperature dependent conductivity was due to thermally activated transport, residence time and ionic scattering of charge carriers. The recovery of conducting and dielectric properties at higher temperatures were due to the transition from graphene–ion–cloud to a graphene–air dielectric multi-nano-capacitor system. The latter had more sp2–carbon cluster concentration and increased electrical percolation supportive of band-like or variable range electron transport. Higher activation energies along ln σT vs T−1/2 plot are associated with delocalization of charge carriers from their potential wells, thermally activated carrier transport and frequency of the electronic field. <br>","PeriodicalId":376919,"journal":{"name":"EnergyRN: Electrochemical Energy Engineering (EnergyRN) (Topic)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124071682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
