Algae application in civil construction: A review with focus on the potential uses of the pelagic Sargassum spp. biomass

A CMOS Algae Growth Period Monitor for Algaculture Applications

“…where the channel length modulation coefficient of a transistor is λ. Besides, c n stands for the code of adjustment sensitivity, and n is equal to S 0 × 2 0 + S 1 × 2 1 . That means n is equal to 0-3 when S 1 S 0 is equal to 00, 01, 10, and 11.…”

“…At the same time, adenosine diphosphate (ADP) and Pi get energy and are synthesized into adenosine triphosphate (ATP). As shown in (1), which is the process of light reaction, a current is thus generated in this biological process. After that, NADPH, ATP, and CO 2 perform a Calvin-Benson cycle to generate CH 2 O and H 2 O.…”

“…The discussions above are the process of Calvin-Benson cycle shown in (2). The NADP + , ADP, and Pi in (2) will be returned to (1) for the next cycle…”

Valorization of waste materials from seaweed industry: An industry survey based biorefinery approach

“…Although a substantial loss of nutritional energy was observed in the residues recovered from hydrocolloid producers, which likely resulted from the inclusion of filter aids as well as generally rigorous physical and chemical treatments during the separation of hydrocolloids, it should be noted that these waste materials were recently promoted as a filter (i.e., additive) material in the fabrication of bioplastic or civil construction materials. 22,30 Given that a handful of industrial hydrocolloid producers we have personally communicated with indicated that much of these solid wastes are either disposed of as a special waste or distributed as an inexpensive soil conditioner to local farmers, exploring their new application routes as a more valuable additive seems particularly promising. While these new high-value applications would also include energy generation (e.g., biogas production via anaerobic digestion), the applicability of nutritionally low-quality residues from hydrocolloid producers in the feed and food sectors should not be completely ruled out.…”

Painéis de partículas multicamadas de bagaço da cana-de-açúcar e Sargassum Pelágico

“…ρ: densidade; IE: inchamento em espessura; MOR: módulo de ruptura; MOE: módulo de elasticidade; AI: adesão interna Fonte: Própria autoria.3.2.2.1 Painéis com fibras de algas marinhasEm pesquisa de revisão desenvolvida porRossignolo et al (2022), observa-se que há uma variedade de espécies de algas marinhas sendo utilizadas como matéria-prima aquicultura, como alternativas ao uso da madeira, contribuindo na preservação das florestas na Indonésia e aumentando a competitividade do mercado de painéis de fibras lignocelulósicas. Segundo os resultados da pesquisa, o conteúdo lignocelulósico da K. alvarezii apresenta valores em torno de 17% de celulose, 21%de hemicelulose e 8%de lignina, valores próximos ao conteúdo lignocelulósico do sargassum pelágico (S. natans e S. fluitans), obtidos por Borines, Leon e Cuello (2013) e Alzate-gaviria et al (2021).…”
