Abstract:

The efficient separation and transfer of photogenerated charge carriers remain a difficult challenge in photocatalysis. While the heterojunctions are an effective strategy for promoting photogenerated charge separation, inefficient migration at the interface often hinders the development. Herein, we report a core-shell organic-inorganic hybrid system, TiO₂@3-aminophenol formaldehyde resin spheres ({001}-TiO₂@APF) for photocatalytic water treatment. The {001}-TiO₂@APF heterojunction achieves a 100% degradation efficiency of glyphosate in 6 h with a reaction rate constant of 0.0068 min^-1, which is 6.2 times that of APF (0.0011 min^-1) and 1.3 times that of bare TiO₂ (0.0051 min^-1). XPS analysis confirms the formation of Ti-O-C covalent bonds at the organic-inorganic interface, which effectively addresses the charge transport challenge and facilitates rapid carrier migration across the heterojunction. This work underscores the importance of atomic-level interfacial engineering in constructing high-efficiency inorganic-organic photocatalysts for sustainable water purification.

The Nucleosome Core Particle

The Nucleosome Core Particle

Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

States of Water

States of Water

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...

Self-Evaluation: Self-Enhancement and Self-Verification

Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The Water Cycle

The Water Cycle

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.

Water and Mineral Acquisition

Water and Mineral Acquisition

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.
