Resumen
Los investigadores desarrollaron sistemas totalmente acuosos novedosos utilizando dextrano (Dex) y polietileno etilfosfonato (PPE). Estos sistemas ofrecen un control mejorado sobre la separación molecular y el diseño de materiales a través de la degradación de polímeros, avanzando en las aplicaciones de encapsulación y administración.
Área de la Ciencia:
- Química de polímeros
- Ciencia de materiales
- Química supramolecular
Sus antecedentes:
- Los sistemas multicompartimentados totalmente acuosos están ganando interés para aplicaciones en separación molecular, diseño de materiales y catálisis.
- Los sistemas existentes a menudo carecen de un control preciso sobre su compartimentación y desmontaje.
- El desarrollo de sistemas que utilizan la degradación de polímeros para ajustar las propiedades es un área activa de investigación.
Objetivo del estudio:
- Introducir nuevos sistemas acuosos bifásicos y emulsiones de agua en agua basados en un polisacárido y un polifosfoéster.
- Investigar la formación y estabilidad de estos sistemas utilizando dextrano (Dex) y polietileno etilfosfonato (PPE).
- Explorar el papel de la degradación ortogonal de polímeros en el control del desmontaje de estos sistemas acuosos.

02:30Water: A Bronsted-Lowry Acid and Base
57.9K
The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, protons are transferred from hydrogen fluoride molecules to water molecules, yielding hydronium ions and fluoride ions:

01:23States of Water
56.4K
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

02:34Water and Mineral Acquisition
35.4K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.

01:19Quality of Water
509
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

The Earth’s hydrosphere includes all of the areas where the storage and movement of water occurs. Since water is the basis of all living processes, the cycling of water is extremely important to ecosystem dynamics.

01:22Effect of Sea Water on Concrete
994
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.
