This paper reviews preparation and applications of amylose supramolecules by means of phosphorylase-catalyzed enzymatic polymerization. When the enzymatic polymerization of α-D-glucose 1-phosphate (G-1-P) as a monomer was carried out in the presence of poly(tetrahydrofuran) (PTHF) of a hydrophobic polyether as a guest polymer, the supramolecule, i.e., an amylose-PTHF inclusion complex, was form...

A novel nanocage structure derived from carboxymethyl-cyclodextrins (CMCDs) intercalated in layered double hydroxides (LDHs), whose gates can be controlled by the process of swelling/drying the CMCD-LDH, has been prepared. Furthermore, the extent of opening of this nanocage structure can be controlled by swelling in different solvents. Dodecylbenzene (DDB) as the guest molecule has been incorpo...

This paper presents an architecture that allows multiple isolated commodity operating systems to run concurrently on a microkernel-based operating system without restricting the CPU architecture of guest operating systems. There are several systems that can execute multiple guest operating systems by using a virtual machine monitor or a microkernel-based operating system. Almost all of them, ho...

A controlled-release formulation of an antihistamine, cetirizine, was synthesized using zinc-layered hydroxide as the host and cetirizine as the guest. The resulting well-ordered nanolayered structure, a cetirizine nanocomposite "CETN," had a basal spacing of 33.9 Å, averaged from six harmonics observed from X-ray diffraction. The guest, cetirizine, was arranged in a horizontal bilayer between ...

Molecular dynamics simulations of the diffusion of trans-2-butene in zeolite type MEL at 623 K have revealed an initial increase of the self-diffusivity with increasing loading, in contrast to simulation data collected for the other butene isomers. This is usually the signature of repulsive guest-guest interactions. At higher loadings, however, the concentration dependence was shown to decrease...

For the first time, host-induced intramolecular charge-transfer complex formation in a guest containing both an electron donor and an electron acceptor is demonstrated in the cucurbit[8]uril cavity, leading to unusual back-folding of the guest molecule.

Deletion of structural elements in cavitand receptors is used to evaluate the thermodynamic and kinetic parameters of binding in these hosts. The use of a bulky guest showcases the importance of host-guest shape adaptations in the molecular recognition process.

Host-guest complexes of calix[4]resorcarene with chiral molecules were efficiently formed by solid-solid grinding and exhibited CD Cotton effects reflecting the absolute configuration of the guest.

C3-Symmetric tricarboxylic acids form dimers through intermolecular hydrogen bonds in nonpolar organic solvents. These dimers recognize lithium ions with high selectivities through the formation of 1 : 1 host-guest complexes between the collapsed dimeric assemblies and guest molecules.

Host-guest complexes between cryptophane-A analogue with butoxy groups (cryptophane-But) and chloromethanes (chloroform, dichloromethane) were investigated in the solid state by means of magic-angle spinning (13)C NMR spectroscopy. The separated local fields method with (13)C-(1)H dipolar recoupling was used to determine the residual dipolar coupling for the guest molecules encaged in the host ...
