A thermophilic cyanobacterium named Thermosynechococcus CL-1 (TCL-1) was cultivated in this study to eliminate the energy input of cooling system in flat plate photobioreactors. Cultivating TCL-1 in the 1.5 cm light path flat plate photobioreactor exhibited stable characteristics for biomass production, CO2 fixation, and carbohydrate production under high illumination conditions (1000 or 2000 μE m(-2) s(-1)). The greatest biomass and carbohydrate productivity, and CO2 fixation rate were recorded at 116, 67, and 170 mg/L/h, respectively, in the 1.5c m light path photobioreactor and under optimal biomass concentration (about 3 g/L). Cultivating Thermosynechococcus CL-1 in flat plate photobioreactors exhibits high potential for biomass production, CO2 fixation and bioethanol production.

The CO-epoxide addition to cyclic carbonate is of great significance but usually requires high temperatures and CO pressures. Herein, a spirobifluorene-based porous organic polymer catalyst is designed with a Co-salen complex immobilized on the backbone (ST-CoSalen-POP) to enable CO fixation under mild conditions. ST-CoSalen-POP possesses a high Co-loading content (9.

Artificial N fixation via the electrocatalytic nitrogen (N) reduction reaction (NRR) has been recently promoted as a rational route toward reducing energy consumption and CO emission as compared with the traditional Haber-Bosch process. Nevertheless, optimizing NRR relies on developing highly efficient electrocatalysts. Herein, we report on the reliable and reproducible synthesis of two promising electrocatalysts in either the presence or absence of Ketjenblack (KB), namely, ZrO-ZrN@KB and ZrO-ZrN systems, synthesized through the nitriding of Zr.

In this research, a sustainable blue-green infrastructure (BGI) was developed to efficiently remove contaminants from stormwater through a combined use of modified porous asphalt (PA) and microalgae cultivation to provide a potential drinking water (DW) source. According to the results, the modified PA with powder activated carbon (PAC) could successfully reduce the level of total suspended solids (TSS), turbidity, polycyclic aromatic hydrocarbons (PAHs), oil and grease to below the DW standards but failed to efficiently remove some heavy metals (HMs) and nutrient pollutants. The results revealed that the treated stormwater was an appropriate medium for microalgae cultivation.

Crassulacean acid metabolism (CAM), a specialized mode of photosynthetic carbon assimilation characterized by nocturnal fixation of atmospheric CO and vacuolar malic acid storage, is found in a wide variety of vascular plant species, mainly those inhabiting water-limited environments. Identifying and characterizing diverse CAM species enhances our understanding of the physiological, ecological, and evolutionary significance of CAM photosynthesis. In this study, we examined the effect of CO elimination on chlorophyll fluorescence-based photosynthetic parameters in two constitutive CAM Kalanchoe species and six orchids.
