Design elements - Chemical elements

The vector stencils library "Chemical elements" contains 118 icon symbols of chemical elements for drawing atoms, structural formulas and ball-and-stick models of inorganic and organic molecules and ions, and schemes of chemical reaction mechanisms.
"In chemistry, the ball-and-stick model is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them. The atoms are typically represented by spheres, connected by rods which represent the bonds. Double and triple bonds are usually represented by two or three curved rods, respectively. In a good model, the angles between the rods should be the same as the angles between the bonds, and the distances between the centers of the spheres should be proportional to the distances between the corresponding atomic nuclei. The chemical element of each atom is often indicated by the sphere's color." [Ball-and-stick model. Wikipedia]

"Tryptophan (IUPAC-IUBMB abbreviation: Trp or W; IUPAC abbreviation: L-Trp or D-Trp; sold for medical use as Tryptan) is one of the 22 standard amino acids and an essential amino acid in the human diet, as demonstrated by its growth effects on rats. It is encoded in the standard genetic code as the codon UGG. Only the L-stereoisomer of tryptophan is used in structural or enzyme proteins, but the R -stereoisomer is occasionally found in naturally produced peptides (for example, the marine venom peptide contryphan). The distinguishing structural characteristic of tryptophan is that it contains an indole functional group." [Tryptophan. Wikipedia]

The vector stencils library "Bank UML component diagram" contains 13 shapes for drawing UML component diagrams.
Use it for object-oriented modeling of your bank information system.
"A component is something required to execute a stereotype function. Examples of stereotypes in components include executables, documents, database tables, files, and library files.
Components are wired together by using an assembly connector to connect the required interface of one component with the provided interface of another component. This illustrates the service consumer - service provider relationship between the two components. ...
When using a component diagram to show the internal structure of a component, the provided and required interfaces of the encompassing component can delegate to the corresponding interfaces of the contained components. ...

This may have a visual stereotype in the top right of the rectangle of a small rectangle with two even smaller rectangles jutting out on the left.
The lollipop, a small circle on a stick represents an implemented or provided interface. The socket symbol is a semicircle on a stick that can fit around the lollipop. This socket is a dependency or needed interface." [Component diagram. Wikipedia]
This example of UML component diagram symbols for the ConceptDraw PRO diagramming and vector drawing software is included in the ATM UML Diagrams solution from the Software Development area of ConceptDraw Solution Park.

The vector stencils library "Mechanics" contains 29 symbol shapes for drawing mechanics experiment schemes and physical diagrams.
"Mechanics ... is the branch of science concerned with the behavior of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. The scientific discipline has its origins in Ancient Greece with the writings of Aristotle and Archimedes. During the early modern period, scientists such as Galileo, Kepler, and especially Newton, laid the foundation for what is now known as classical mechanics. It is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. It can also be defined as a branch of science which deals with the motion of and forces on objects." [Mechanics. Wikipedia]
