Spicing up nutrition: investigation of trace elements in some spices locally sold in two markets in Kisumu-Kenya.

Spices are integral to Kenyan cuisine, adding depth of flavour and aroma to dishes. Information on the levels of macro- and micronutrients in these spices is scarce, as they are sold locally in Kisumu City, Kenya; however, these species have medicinal value. The study reports the trace elements composition of eight selected spices (black pepper, cloves, ginger, cardamom, turmeric, cumin, red chillies, and garlic) sold in two open-air markets in Kisumu City.

Sustainable Hydrothermal and Solvothermal Synthesis of Advanced Carbon Materials in Multidimensional Applications: A Review.

The adoption of green technology is very important to protect the environment and thus there is a need for improving the existing methods for the fabrication of carbon materials. As such, this work proposes to discuss, interrogate, and propose viable hydrothermal, solvothermal, and other advanced carbon materials synthesis methods. The synthesis approaches for advanced carbon materials to be interrogated will include the synthesis of carbon dots, carbon nanotubes, nitrogen/titania-doped carbons, graphene quantum dots, and their nanocomposites with solid/polymeric/metal oxide supports.

trans-Dichloridobis[dicyclo-hex-yl(2,4,6-trimethyl-phen-yl)phosphane-κP]palladium(II).

The title compound, [PdCl(2)(C(21)H(33)P)(2)], forms a monomeric complex with a trans-square-planar coordination geometry about the Pd(II) atom which lies on an inversion centre. The Pd-P bond lengths are 2.3760 (13) Å, while the Pd-Cl bond lengths are 2.

trans-Carbonyl-chloridobis[diphen-yl(4-vinyl-phen-yl)phosphane-κP]rhodium(I).

In the title compound, trans-[RhCl(C(20)H(17)P)(2)(CO)], the Rh(I) atom is situated on a center of symmetry, resulting in a statistical 1:1 disorder of the chloride [Rh-Cl = 2.383 (2) Å] and carbonyl [Rh-C = 1.752 (7) Å] ligands.

trans-Dichloridobis[dicyclo-hex-yl(phen-yl)phosphane-κP]palladium(II).

The title compound, [PdCl(2){P(C(6)H(11))(2)(C(6)H(5))}(2)], forms a monomeric complex with a trans-square-planar geometry. The Pd-P bond lengths are 2.3343 (5) Å, as the Pd atom lies on an inversion centre, while the Pd-Cl bond lengths are 2.

(Acetyl-acetonato-κ(2)O,O')carbon-yl[tris-(naphthalen-1-yl)phosphane-κP]rhodium(I) acetone hemisolvate.

The title compound, [Rh(C(5)H(7)O(2))(C(30)H(21)P)(CO)]·0.5C(3)H(6)O, has two different complex molecules in the asymmetric unit, with the Rh(I) atoms in slightly distorted square-planar coordination environments. The molecules are packed as two monomeric mol-ecules with one acetone solvent mol-ecule sitting at the centre.

cis-Dichloridobis[diphen-yl(4-vinyl-phenyl)phosphane-κP]platinum(II).

The title compound, [PtCl(2)(C(20)H(17)P)(2)], forms a monomeric cis-square-planar geometry. The Pt-P bond lengths are 2.2489 (9) and 2.
