Lepidolite ore

It is a lithium containing mica mineral with a chemical composition of K (Li, Al) 2-3 (Si3Al) O10 (F, OH) 2, belonging to the mica group of minerals. Usually presented in shades of purple, pink, gray, or green, with a pearl luster and a layered structure that can be peeled off into thin sheets. Mainly produced in granite, pegmatite, and certain metamorphic rocks, it is one of the important mineral resources for extracting lithium and is not commonly found in nature. Due to the wide applications of lithium in modern industry, such as battery manufacturing, ceramics, glass, and lubricants, the mining and utilization of lithium mica have important economic value.

Cobalt ore

It is a chemical element with the chemical symbol Co and an atomic number of 27. Similar to nickel, it mainly exists in the form of compounds in the Earth's crust, except for a small amount of cobalt found in natural meteorite iron alloys. Pure cobalt obtained through reduction smelting is a hard, shiny, slightly brittle gray metal. Cobalt based blue pigments (such as cobalt blue) have been used in jewelry and painting since ancient times, as well as giving glass its unique blue hue. It is widely used in art and industry due to its stability and vibrant blue color. Cobalt compounds are also very important in ceramic and glass manufacturing, as they can produce various shades ranging from deep blue to light blue.

Spiral arranged nanowires (microscopic 3D schematic diagram)

Spiral arranged nanowires are a type of nanomaterial with a helical structure, typically formed by self-assembly or guided growth of one-dimensional nanowires. This structure has important applications in materials science and nanotechnology.

Spiral protease

Spiral protease is a type of protease with a spiral structure that participates in the degradation and metabolism of proteins. Spiral proteases typically have alpha helix or beta helix structures, which contribute to the stability and function of proteases.

Phospholipid bilayers (microscopic 3D schematic)

Phospholipid bilayer is a structure composed of two layers of phospholipid molecules and is a fundamental component of the cell membrane. A hydrophilic "head" and a hydrophobic "tail". The hydrophilic head faces the aqueous phase, while the hydrophobic tails approach each other, forming a bilayer structure. Having fluidity, allowing embedded proteins to move within the membrane. Being able to selectively allow certain substances to pass through while blocking others. The phospholipid bilayer isolates the interior of cells from the external environment. Through embedded proteins, phospholipid bilayers can regulate the entry and exit of ions, nutrients, and waste.

Multilayer phosphorene structure (microscopic 3D schematic diagram)

Phosphorene is a two-dimensional material composed of a single layer of black phosphorus atoms, possessing unique physical and chemical properties. Phosphocene is a single-layer phosphorus atom detached from black phosphorus, exhibiting a honeycomb like lattice arrangement but with a wavy bent structure.

Cubic porous skeleton

A cubic porous skeleton is a structure with a cubic shape and containing a large number of pores. This structure has wide applications in materials science and biotechnology, especially in fields such as bone scaffolds and gas storage.

Immunoglobulin (Microscopic 3D Schematic)

Antibody (Ab), also known as immunoglobulin (Ig), is a large Y-shaped protein mainly secreted by plasma cells and used by the immune system to identify and neutralize foreign substances such as bacteria, viruses, and other pathogens. It is only found in the extracellular fluid of vertebrates, such as plasma, and on the cell membrane surface of B cells. An antibody can uniquely recognize a specific foreign target through its variable region, which is called an antigen.

Staphylococcus aureus (microscopic 3D schematic)

Staphylococcus aureus (S. aureus), also known as "Staphylococcus aureus", belongs to the genus Staphylococcus and is a representative of Gram positive bacteria. It is a common foodborne pathogenic microorganism. The most suitable growth temperature for this bacterium is 37 ℃, pH 7.4, high salt tolerance, and can grow in an environment with a salt concentration close to 10%. Staphylococcus aureus often parasitizes the skin, nasal cavity, throat, gastrointestinal tract, abscess, and purulent sores of humans and animals, and is also ubiquitous in environments such as air and sewage.

Molecular structure of cyclodextrin

Cyclodextrin (CD) is a class of cyclic oligosaccharides formed by glucose units connected by α -1,4-glycosidic bonds. According to the number of glucose units contained, cyclodextrins are mainly divided into three types: alpha cyclodextrin (6 glucose units), beta cyclodextrin (7 glucose units), and gamma cyclodextrin (8 glucose units).

Core-shell micelle structure

Core shell micelles are nanostructures formed by self-assembly of amphiphilic molecules (such as block copolymers) in selective solvents. Its structural characteristics are a hydrophobic core and a hydrophilic shell. Composed of hydrophobic molecular segments, aggregated at the center of micelles, avoiding contact with water or other polar solvents. Composed of hydrophilic molecular segments, surrounded by a hydrophobic core, and interacting with water or other polar solvents.

Synaptic transmission in frontal cortex (medical 3D schematic)

The nervous system is composed of a large number of neurons. These neurons are not connected by protoplasm in structure, only in contact with each other, and the site of contact is called a synapse. Due to the different contact sites, synapses can be mainly divided into three categories: axon cytoplasmic synapses; Axonal dendritic synapse; Axon axon synapse. The axon terminals of a neuron repeatedly branch and swell into cup-shaped or spherical shapes, known as synaptic bodies, which come into contact with the cell bodies or processes of postsynaptic neurons. A presynaptic neuron can form synapses with many postsynaptic neurons, and a postsynaptic neuron can also form synapses with the axon terminals of many presynaptic neurons.
