Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Carbon-dioxide Fixation

Carbon-dioxide Fixation

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Energy Line and Hydraulic Gradient Line

Energy Line and Hydraulic Gradient Line

Based on Bernoulli's equation, the energy line (EL) and hydraulic grade line (HGL) provide graphical representations of energy distribution in a fluid flow system. For steady, incompressible, inviscid flows, Bernoulli's equation is expressed as:

Carbon Skeletons

Carbon Skeletons

Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Microbial Mats

Microbial Mats

Microbial communities forming biofilms and mats represent complex, spatially structured ecosystems where metabolic processes are stratified according to light, oxygen, and nutrient gradients. Biofilms are initial colonization stages, only a few millimeters thick, while mature microbial mats can reach centimeter-scale thickness and display intricate vertical organization. Their structural and functional heterogeneity allows microorganisms to occupy distinct ecological niches within a few...

Background:

Exploration of novel carbon allotropes is crucial for advancing materials science.
3,4-connected carbon nets offer unique structural and electronic properties.
Hypothetical materials require theoretical validation before experimental synthesis.

Purpose of the Study:

To present theoretical calculations for a novel hypothetical 3,4-connected carbon net, named squaroglitter.
To investigate the structural, electronic, and stability properties of squaroglitter.
To explore potential applications and relationships with known carbon structures.

Main Methods:

Density Functional Theory (DFT) based calculations.
Geometry optimization to determine stable structural parameters.
Electronic band structure calculations to determine the bandgap.

Main Results:

A new hypothetical 3,4-connected carbon net (squaroglitter) with tetragonal P4/mmm symmetry was designed.
Optimized geometry revealed normal bond distances, with some elongations in cyclobutane rings.
Squaroglitter exhibits an indirect bandgap of approximately 1.0 eV.
The calculated density is close to graphite, and the structure is more stable than other 3,4-connected nets.
A relationship to (4,4)nanotubes and potential for metal needle threading were explored.
