Plastic crystals undergo phase transitions with unusually large volume and entropy changes related to strong molecular orientational disordering. These features have led a resurgent interest in these materials because recently they shown great potential solid-state cooling applications driven by pressure. Here we demonstrate that two plastic derived from adamantane -1-Br-adamantane 1-Cl-adamant...

In this investigation, a systematic attempt has been made to understand the interaction between adamantane and benzene using both ab initio and density functional theory methods. C–H...π type of interaction between C–H groups of adamantane and π cloud of benzene is found as the important attraction for complex formation. The study also reveals that the methylene (-CH2) and methine (-CH) groups ...

Rhombellanes are mathematical structures existing in various environments, in crystal or quasicrystal networks, or even in their homeomorphs, further possible becoming real molecules. Rhombellanes originate in the K2.3 complete bipartite graph, a tile found in the linear polymeric staffanes. In close analogy, a rod-like polymer derived from hexahydroxy-cyclohexane was imagined. Further, the ide...

objective: the use of antiretroviral drugs has proven remarkably effective in controlling the progression of human immunodeficiency virus (hiv) disease, but these benefits can be compromised by the development of drug resistance. this study aims to assess the drug resistance profile of the pr gene in highly active antiretroviral therapy (haart)-treated and naïve hiv-1 infected patients. metho...

objectives in this study, we explored a physical method of converting drug-resistant bacteria to drug-sensitive ones. materials and methods this is an in vitro case-control study, performed at the ionizing and non-ionizing radiation protection research center (inirprc), shiraz university of medical sciences (sums), shiraz, iran in 2014. all experiments were carried out using gram-negative bacte...

conclusions these findings underscored the importance of monitoring and developing guidelines for better management of infectious diarrhoea in bangladesh and elsewhere. background diarrhoea is considered as the most widespread illness occurring in bangladesh. in addition, the growing antimicrobial resistance of diarrhoeal pathogens in this developing country hardens physicians to supervise pati...

extensively drug-resistant tuberculosis (xdr-tb) is a new challenge for tuberculosis control programs. lack of effective drugs and high rate of failure in treatment and mortality is a major threat for public health. treatment of this serious infection needs well-designed individualized dosage regimen and powerful national tb program. in this review we will describe the xdr-tb definition and its...

We report the assembly and thermal transformation of linear diamondoid assemblies inside carbon nanotubes. Our calculations and observations indicate that these molecules undergo selective reactions within the narrow confining space of a carbon nanotube. Upon vacuum annealing of adamantane molecules encapsulated in a carbon nanotube, we observe a sharp Raman feature at 1857 cm(-1), which we int...

Doubly connected cyclodextrin (CD) dimers, called duplexes, have the ability to cross-link hydrosoluble biopolymers grafted with a hydrophobic moiety, inducing a viscosity increase of the solution through formation of stable supramolecular assemblies. CD duplexes behave differently according to the nature of their inter-CD links. CD duplex with hydrophobic links has a better affinity for adaman...
