M.B., and F. F. Burghard, M.D. Part VI., Section II. Pp. xxiii., 559. London: Longmans, Green, and Co. 1903. This volume, which is one of the largest of the series, is also perhaps the best. The subjects treated of are of great importance, and are very ably dealt with. Our information with regard to many has greatly advanced during recent years, and such advance is fully brought under our notic...

In recent years, a plethora of theoretical carbon allotropes have been proposed, none of which has been experimentally isolated. We discuss here criteria that should be met for a new phase to be potentially experimentally viable. We take as examples Haeckelites, 2D networks of sp(2)-carbon-containing pentagons and heptagons, and "penta-graphene," consisting of a layer of pentagons constructed f...

In this study, different derivative spectrophotometric methods are proposed for the simultaneous determination of chlorpheniramine maleate (CP), phenylephrine HCl (PE) and phenylpropanolamine HCl (PP) in their ternary mixtures and in pharmaceutical dosage forms. Spectra of single component and ternary mixtures of various concentrations and combinations from zero- to fourth-derivation were obtai...

We introduce an effective tight-binding model to discuss penta-graphene and present an analytical solution. This model only involves the π-orbitals of the sp(2)-hybridized carbon atoms and reproduces the two highest valence bands. By introducing energy-dependent hopping elements, originating from the elimination of the sp(3)-hybridized carbon atoms, also the two lowest conduction bands can be w...

The title tricyclic diene, C(24)H(22)Cl(2), is the product of thermal ring-opening of a corresponding basketane (penta-cyclo-[4.4.0.0(2,5).0(3,8).0(4,7)]deca-ne) derivative. The cyclo-butene ring is planar to within 0.0032 (12) Å and its geometry is normal. The two 4-chloro-phenyl groups are oriented in an approximately face-to-face conformation with a dihedral angle of 44.14 (6)° between them....

The title compound, C(10)H(11)N(2)O(2)P·H(2)O, contains a tetra-coordinate penta-valent P atom. The phosphinate group plays a predominant role in the cohesion of the crystal structure by forming chains along the b axis via inter-molecular C-H⋯O hydrogen bonds. These chains are connected by O-H⋯O and N-H⋯O hydrogen bonding involving the lattice water.
