Techniques regarding post polymerization modifications to polycarbonate polymers via a flow reactor are provided. For example, one or more embodiments described herein can comprise a cyclic carbonate monomer that can be employed to facilitate polymerization of one or more polycarbonate platforms susceptible to post polymerization modification. For instance, one or more embodiments can regard a cyclic carbonate molecular backbone covalently bonded to an aryl halide functional group via in accordance with a chemical structure selected from the group consisting of:

##STR00001##

In the chemical structures, “R.sub.1” can be selected from the group consisting of a hydrogen atom and a functional group comprising a first alkyl group; “L” can represent a linkage group, comprising: a second alkyl group and an end group having at least one member selected from the group consisting of an oxygen atom and a nitrogen atom; and “A” can represent the aryl halide functional group.

A compound represented by formula (i) has, as K.sup.i1 in the formula (i), a structure represented by any one of formula (K-1) to formula (K-3). When used in a liquid crystal composition, it adheres to substrates which hold the liquid crystal composition (liquid crystal layer) therebetween, thereby permitting liquid crystal molecules to be maintained in the state of being aligned in the vertical direction. The liquid crystal composition using the compound enables liquid crystal molecules to be aligned even when the PI layer is not provided (vertical alignment of liquid crystal molecules is induced without the voltage applied and horizontal alignment of liquid crystal molecules is realized with the voltage applied). It is possible to provide a polymerizable compound being excellent in storability and capable of uniform vertical alignment of liquid crystal molecules with no PI layer provided.

The invention provides certain specific lipid nanoparticles comprising: (a) one or more nucleic acid molecules; (b) cholesterol; (c) DSPC; (d) PEG-C-DMA; and (b) a cationic lipid of formula CL1 or CL2, and pharmaceutical compositions comprising the lipid nanoparticles. The lipid nanoparticles and pharmaceutical compositions are particularly useful for delivering a nucleic acid to a patient (e.g. a human) or to a cell.

Provided are synthetic dendrimer calibrants for mass spectrometry. The calibrants are distinguished by their relative case and rapidity of synthesis, comparatively low cost, long shelf life, high purity, and amenability to batch synthesis as mixtures. The latter characteristic enables parallel preparation of higher molecular weight compounds displaying useful distributions of discrete molecular weights, thereby providing multi-point mass spectrometry calibration standards. Methods of making, tuning and using said calibrants are provided.
