A trunnion (from Old French trognon 'trunk') [1] is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. First associated with cannons, they are an important military development.
Molecular machines are a class of molecules typically described as an assembly of a discrete number of molecular components intended to produce mechanical movements in response to specific stimuli, mimicking macromolecular devices such as switches and motors.
The structure of the machine is based on a rotaxane, which is a molecular ring sliding along a molecular axle. The ring carries a thiolate group, which removes amino acids in sequence from the axle, transferring them to a peptide assembly site.
Ádám István Mechler is a materials scientist and academic most known for his research on intermolecular interactions in physical chemistry, as well as on molecular machines, hierarchical metamaterials, and self-assembling systems inspired by biology. [1]
The 'assembly index' is the number of steps on a shortest path producing the object. [5] For such shortest path, the assembly space captures the minimal memory, in terms of the minimal number of operations necessary to construct an object based on objects that could have existed in its past. [5]
A DNA machine is a molecular machine constructed from DNA. Research into DNA machines was pioneered in the late 1980s by Nadrian Seeman and co-workers from New York University . DNA is used because of the numerous biological tools already found in nature that can affect DNA, and the immense knowledge of how DNA works previously researched by ...
Robert L. Norton is an American engineer, academic and author.He is the President of Norton Associates [1] and the Milton P. Higgins II Distinguished Professor Emeritus in Mechanical Engineering at the Worcester Polytechnic Institute.
CAM software automates the process of converting 3D models into tool paths, the route the multiaxis machine takes to mill a part (Fig. 1). This software takes into account the different parameters of the tool head (in the case of a CNC router, this would be the bit size), dimensions of the blank, and any constraints the machine may have.
