In statistical mechanics, the Zimm–Bragg model is a helix-coil transition model that describes helix-coil transitions of macromolecules, usually polymer chains. Most models provide a reasonable approximation of the fractional helicity of a given polypeptide; the Zimm–Bragg model differs by incorporating the ease of propagation (self-replication) with respect to nucleation.
Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input. [2] Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion (via protein dynamics ), some groups also use the term when referring to non-biological, non-peptide synthetic ...
A proposed branch of research is the integration of molecular motor proteins found in living cells into molecular motors implanted in artificial devices. Such a motor protein would be able to move a "cargo" within that device, via protein dynamics , similarly to how kinesin moves various molecules along tracks of microtubules inside cells.
Wall Street's main indexes slipped on Tuesday, weighed down by technology stocks after a batch of upbeat economic data stoked uncertainty among investors about the pace of monetary policy easing ...
Today's price pop is the result of an extremely bullish note from Morgan Stanley, in which analyst Adam Jonas more than doubled his stock price target to $320, from $153. The new forecast is based ...
While it didn't hold all of its gains, the stock was still higher by 4% as of 11:35 a.m. ET. The move has increased the sharp rise in Lucid shares over the past month to more than 60%. Where to ...
Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
A future nanocar with a synthetic molecular motor has been developed by Jean-Francois Morin et al. [14] It is fitted with carborane wheels and a light-powered helicene synthetic molecular motor. Although the motor moiety displayed unidirectional rotation in solution, light-driven motion on a surface has yet to be observed.
