The translational Helmholtz free energy cost of restricting a dilute ideal gas from a volume to an area at the same temperature. For identical particle number and mass,Here is the thermal de Broglie wavelength. This contribution is positive for ; a favourable binding energy must be added separately to predict net adsorption.
Fluid added mass increases inertia but need not alter the same restoring force. A submerged spring's constant buoyancy shifts equilibrium, whereas a pendulum's buoyancy reduces its restoring torque. Thus an unbounded-fluid sphere has spring frequency factor and downward-pendulum factor . The latter stable configuration requires .
A signalling adaptor with several recognition domains, useful in reconstituted studies of multivalency and assembly.
Benzoyl chloride is the aromatic acyl chloride . Its acyl carbon is susceptible to attack by a nucleophile, followed by chloride departure.
A actin filament assembled from actin subunits. actin filament mass and actin filament number are distinct quantities; subunit exchange can continue while the total mass is approximately steady.
An individual soluble actin subunit. Total actin monomer concentration and concentration available for assembly differ when actin monomers are bound by sequestering molecules.
A spiroacetal is an acetal whose central acetal carbon is the shared atom of two rings. The ring systems meet at that one atom rather than sharing an edge.
Its conformational preference can reflect stereoelectronic and steric contributions, including anomeric effects. Spiroacetal geometry is important in several natural-product frameworks because the same connectivity can support different three-dimensional arrangements.
2,2-Dimethoxypropane is the dimethyl acetal of acetone. Reaction with a diol under acid catalysis can form an acetonide and two methanol molecules.
A cyclic sugar-derived acetal analogue with an anomeric carbon–sulfur bond. Its anomeric configuration and conformational preference must be distinguished from one another.
An acetal derived formally from a ketone, with two carbon substituents and two oxygen substituents at its acetal carbon.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
