Summary
Novel carbon-aluminum (Cn Al12) nanoclusters show peak stability for two carbon atoms. This finding is linked to structural relaxation and impacts their electronic properties.
Area of Science:
- Computational chemistry
- Materials science
- Nanotechnology
Background:
- Core-shell nanoclusters are crucial in materials science for tunable properties.
- Understanding the stability and electronic behavior of carbon-aluminum (Cn Al12) clusters is key for designing new materials.
Purpose of the Study:
- To investigate the structural, energetic, and electronic properties of novel Cn Al12 core-shell nanoclusters.
- To explore the influence of carbon atom number (n=1-4) and isomeric structure on cluster characteristics.
Main Methods:
- Density functional calculations were employed to model and analyze the nanoclusters.
- Calculations included energetics, stability, ionization energies, and electron affinities for encapsulated and externally bound isomers.
Main Results:
- A peak in stability was observed for Cn Al12 clusters when n=2, for both core-shell and externally bound configurations.
- This stability peak correlates with the relaxation of cluster components upon dissociation.
- Trends in ionization energies and electron affinities were analyzed, highlighting the contributions of carbon and aluminum.
Conclusions:
- The number of carbon atoms and the specific morphology significantly influence the properties of Cn Al12 nanoclusters.
- The n=2 configuration represents a particularly stable and interesting motif for these carbon-aluminum systems.

01:20Introduction to Cognitive Psychology
2.7K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.

3.6K
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

16.3K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and...

01:14Motor and Sensory Areas of the Cortex
7.9K
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex....

01:28Automatic Processing and Automatic Social Behavior
371
Automatic processing refers to the cognitive operations that occur without conscious intent or awareness, playing a fundamental role in shaping social cognition and behavior. These processes enable individuals to navigate complex social environments efficiently by relying on mental shortcuts and pre-existing knowledge structures known as schemas. One of the most influential mechanisms underlying automatic processing is priming, which subtly activates mental representations through exposure to...
