The main objective of this investigation was to evaluate fruits of C. chinense accessions for their concentration of β-carotene, ascorbic acid, and phenols for use as parents in breeding for these phytochemicals. Mature fruits of 63 accessions of C....

Hydrogen-bond-supported dimeric boron complexes of potentially tetradentate β-diketiminate ligands.

Dalton transactions (Cambridge, England : 2003)

Barbon SM, Staroverov VN, Boyle PD, Gilroy JB.
PMID: 24096386
Dalton Trans. 2014 Jan 07;43(1):240-50. doi: 10.1039/c3dt52188e.

Two dimeric boron complexes of potentially tetradentate and trianionic β-diketiminate ligands bearing phenol substituents were prepared and characterized. The synthetic routes employed were designed to circumvent the undesirable formation of β-ketimines and 2-methylbenzoxazoles observed when traditional synthetic routes toward...

BACKGROUND: Musa seminifera Lour is a tree-like perennial herb that has been used in folk medicine in Bangladesh to heal a number of ailments.OBJECTIVE: To evaluate the antioxidant, analgesic, antidiarrheal, anthelmintic activities, and general toxicity of the ethanol extract...

The role of the testa during development and in establishment of dormancy of the legume seed.

Frontiers in plant science

Smýkal P, Vernoud V, Blair MW, Soukup A, Thompson RD.
PMID: 25101104
Front Plant Sci. 2014 Jul 17;5:351. doi: 10.3389/fpls.2014.00351. eCollection 2014.

Timing of seed germination is one of the key steps in plant life cycles. It determines the beginning of plant growth in natural or agricultural ecosystems. In the wild, many seeds exhibit dormancy and will only germinate after exposure...

Effects of experimental conditions on the morphologies, structures and growth modes of pulsed laser-deposited CdS nanoneedles.

Nanoscale research letters

Li H, Chen L, Zhao Y, Liu X, Guan L, Sun J, Wu J, Xu N.
PMID: 24559455
Nanoscale Res Lett. 2014 Feb 22;9(1):91. doi: 10.1186/1556-276X-9-91.

CdS nanoneedles with different morphologies, structures, and growth modes have been grown on Ni-coated Si(100) surface under different experimental conditions by pulsed laser deposition method. The effects of catalyst layer, substrate temperature, and laser pulse energy on the growth...

Optimal proportional relation between laser power and pulse number for the fabrication of surface-microstructured silicon.

Applied optics

Appl Opt. 2011 Aug 20;50(24):4765-8. doi: 10.1364/AO.50.004765.

We experimentally demonstrate that, under the same laser fluence, there exists an optimal proportional relation between the laser power and pulse number for the fabrication of surface-microstructured silicon. During this fabrication process, the pulse number represents the interaction time...

Synthesis, field-emission and electric properties of metastable phase VO2 (A) ultra-long nanobelts.

Mononuclear Zn(ii) complexes with the general formula [Zn(L)2] have been synthesized in good yields by reacting Zn(OAc)2 with HL in a ratio of 1 : 2 in methanol solvent. Here L is the deprotonated form of 6-[(quinolin-8-ylamino)methylene]cyclohexa-2,4-dienone (HL(1)), 4-chloro-6-[(quinolin-8-ylamino)methylene]cyclohexa-2,4-dienone...
