Assessing the Operational Feasibility of Integrating Point-of-Care G6PD Testing into Malaria Management in Vietnam.

cases represent more than 50% of a diminishing malaria case load in Vietnam. Safe and effective radical cure strategies could support malaria elimination by 2030. This study investigated the operational feasibility of introducing point-of-care quantitative glucose-6-phosphate dehydrogenase (G6PD) testing into malaria case management practices.

A theoretical approach to the role of different types of electrons in planar elongated boron clusters.

We analyze the thermodynamic stability of some small elongated boron clusters and confirm the relationship between their planarity and their inherent electron configuration […σππ]. Delocalized σ electrons in an elongated bare boron cluster and 2c-2e C-H bonds in a corresponding elongated hydrocarbon play a vital role in maintaining their planar structure. Through the eigenstates derived from a model of a particle moving in a rectangle, the rectangle model, our study suggests that the larger planar elongated boron clusters are not thermodynamically stable.

B@Si: strong stabilizing effects of a triatomic cyclic boron unit on tubular silicon clusters.

Remarkably strong effects of the aromatic B cycle in stabilizing tubular silicon clusters were observed for the first time. The doped cluster B@Si presents a novel structural motif for silicon clusters in which a B cycle is encapsulated into a (6 × 2) Si prism giving rise to a high symmetry stable tubular structure (D). A large amount of electron density is transferred to the boron cycle, and the B unit not only retains a delocalized bonding pattern within the Si prism but also enables a two-fold aromaticity for the resulting silicon double ring.

Electronic Structure and Thermochemical Parameters of the Silicon-Doped Boron Clusters BnSi, with n = 8-14, and Their Anions.

We performed a systematic investigation on silicon-doped boron clusters BnSi (n = 8-14) in both neutral and anionic states using quantum chemical methods. Thermochemical properties of the lowest-lying isomers of BnSi(0/-) clusters such as total atomization energies, heats of formation at 0 and 298 K, average binding energies, dissociation energies, etc. were evaluated by using the composite G4 method.

A disk-aromatic bowl cluster B30: toward formation of boron buckyballs.

The B30 boron cluster has a bowl rather than a double-ring or a triple-ring tubular structure. This bowl isomer exhibits disk-aromaticity similar to that found for B20(2-) and B19(-) clusters. We confirmed that the concept of disk-aromaticity can be applied to both planar and non-planar systems.
