In a virtualized environment, it is not difficult to retrieve guest OS information from its hypervisor. However, it is very challenging to retrieve information in the reverse direction, i.e., retrieve the hypervisor information from within a guest OS, which remains an open problem and has not yet been comprehensively studied before. In this paper, we take the initiative and study this reverse i...
Allowing a guest to have direct, privileged access to hardware can enhance its performance and functionality. Privileged access to hardware and the VMM also enables and improves the performance of virtualization services by allowing portions of their implementations to be hoisted into the guest, even uncooperatively. However, granting such privilege currently requires that the entire guest be t...
A molecular receptor consisting of a spacer bearing two cofacially disposed terpyridyl-palladium-ligand (terpy-Pd-L) units rigidly separated by about 7 A has been investigated for molecular recognition of planar aromatic molecules. It is found that although the receptor forms stable 1:2 host-guest association complexes with 9-methylanthracene (9-MA), the guest undergoes very rapid site exchange...
We present clear evidence that the global (macroscopic) transport from/to mesoporous materials is significantly affected by the interactions between the mesoporous host and the guest molecules. The problem is considered in a most general way so the solutions apply for a variety of cases such as the release of a guest from porous matrices, catalysis occurring in porous materials or processes tak...

This study offers a detailed mechanistic investigation of host-guest encapsulation behavior in a new enzyme-mimetic metal-ligand host and provides the first observation of a conformational selection mechanism (as opposed to induced fit) in a supramolecular system. The Ga4L4 host described features a C3-symmetric ligand motif with meta-substituted phenyl spacers, which enables the host to initia...
We report on the effects of introducing guest molecules into a functionalized anthradithiophene (ADT) host on the photoluminescent (PL) and photoconductive properties of solution-deposited thin films. An addition of 0.1 wt % of an ADT derivative with cyano end groups (ADT-TIPS-CN) to a fluorinated ADT derivative (ADT-TES-F) resulted in the near complete quenching of the fluorescence spectrum of...
CONSPECTUS: Donald Cram's pioneering Nobel Prize-winning work on host-guest molecules led eventually to his creation of the field of container molecules. Cram defined two types of container molecules: carcerands and hemicarcerands. Host-guest complexes of carcerands, called carceplexes, are formed during their synthesis; once a carceplex is formed, the trapped guest cannot exit without breaking...
