Article Abstract
The chemical absorption of carbon dioxide (CO2) is a technique used for the mitigation of the greenhouse effect. However, this process consumes high amounts of energy to regenerate the absorbent and to separate the CO2. CO2 removal by microalgae can be obtained via the photosynthesis process. The objective of this study was to investigate the cultivation and the macromolecules production by Spirulina sp. LEB 18 with the addition of monoethanolamine (MEA) and CO2. In the cultivation with MEA, were obtained higher results of specific growth rate, biomass productivity, CO2 biofixation, CO2 use efficiency, and lower generation time. Besides this, the carbohydrate concentration obtained at the end of this assay was approximately 96.0% higher than the control assay. Therefore, Spirulina can be produced using medium recycle and the addition of MEA, thereby promoting the reduction of CO2 emissions and showing potential for areas that require higher concentrations of carbohydrates, such as in bioethanol production.

Metal-organic frameworks (MOFs) are transformative platforms for heterogeneous catalysis, but distinguishing atomically dispersed metal sites from subnanometric clusters remains a major challenge. This often demands the integration of multiple characterization techniques, many of which either lack the resolving power to distinguish active sites from their surrounding environments (e.g.

Perylene diimide (PDI) radical anions have attracted increasing attention as hypoxia-responsive photothermal agents due to their strong near-infrared (NIR) absorption and efficient photothermal conversion. However, their biomedical application is often limited by aggregation-induced quenching and poor structural tunability. In this work, we report a rationally engineered four-arm PDI derivative (PDI-4Alky·4Cl) bearing terminal alkyne groups, which not only suppresses π-π stacking steric and electrostatic repulsion, but also serves as a versatile molecular scaffold for further functionalization.

In this study, potato slices were fried in four different vegetable oils (corn, olive, palm olein, and sunflower) to investigate how oil type influences the characteristics of potato chips. The diffusion coefficient of oils was attempted to be correlated with the final moisture, oil uptake, and textural parameters of potato chips. The diffusion coefficients were determined using two approaches.

Exhaled breath analysis offers noninvasive, early lung cancer detection via volatile organic compound (VOC) biomarkers, surpassing blood-based methods. Surface-enhanced Raman spectroscopy (SERS) is ideal for this purpose, combining molecular fingerprint specificity with single-molecule sensitivity. However, conventional SERS substrates face a fundamental limitation: while porous materials such as metal-organic frameworks effectively adsorb VOCs through their subnanometer pores (0.

Microplastics are ubiquitous in the environment, accumulate hydrophobic organic contaminants, and suppress the photodegradative loss of these contaminants. Thus, they have the potential to act as vectors for contaminant uptake by organisms and transport to remote regions. Our current understanding of microplastic-sorbed contaminant photodegradation is drawn from experiments with unpigmented microplastics, but the interaction of pigments with light may alter the loss and corresponding persistence of sorbed contaminants.
