METODOLOGIE CROMATOGRAFICHE NELLO STUDIO DEI PROCESSI DI ADSORBIMENTO [PDF]

, 2010
In analytical chromatography, the sample we analyze is usually rather dilute and allows the development of a rather straightforward method. Due to the minute concentrations we deal with in analytical chromatography, we face a linear behavior.

Morphological Characterization of Spherulites in Silk‐Polycaprolactone Mixtures: Implications for Textured Materials

Advanced Materials Interfaces, EarlyView.
Blending silk fibroin with polycaprolactone alters crystalline organization and surface morphology. Low fibroin levels promote ring‐banded spherulites, while higher contents generate porous, pit‐like textures, though overall crystallinity remains unchanged. Solvent evaporation further modulates surface patterns.

From Surface to Bulk Activation: Tailoring the Porosity and Surface Chemistry of Resorcinol‐Formaldehyde Carbon Sorbents for Atmospheric Water Harvesting

Advanced Materials Interfaces, EarlyView.
A bulk activation route to produce nanoporous carbons for atmospheric water harvesting by incorporating potassium hydroxide during resorcinol‐formaldehyde polycondensation. These high‐oxygen sorbents deliver daily water yields up to 23 L kg−1 day−1 with great cyclability, providing a scalable solution for water production in diverse climates.

Batch Adsorption of Tannins from Stevia Leaf Extract using Activated Carbon: An Investigation into Adsorption Isotherms and Adsorption Energy

Jurnal Rekayasa Kimia & Lingkungan
Stevia leaf extract (Stevia rebaudiana Bertoni) could have been utilized as an alternative natural sweetener because it possessed a sweetness level 300 times that of sucrose sugar. However, stevia leaf extract still contained a bitter taste attributed to
