Enhanced Performance of Carbon-Selenide Composite with LaCeNiO Perovskite Oxide for Outstanding Counter Electrodes in Platinum-Free Dye-Sensitized Solar Cells.

For large-scale applications, dye-sensitized solar cells (DSSCs) require the replacement of the scarce platinum (Pt)-based counter electrode (CE) with efficient and cheap alternatives. In this respect, low-cost perovskite oxides (ABO) have been introduced as promising additives to composite-based CEs in Pt-free DSSCs. Herein, we synthesized composites from LaCeNiO (L) perovskite oxide and functionalized-multiwall-carbon-nanotubes wrapped in selenides derived from metal-organic-frameworks (f-MWCNT-ZnSe-CoSe, "F").

The "collerette" technique for skin excision and biopsy: an efficient method for managing lentigo maligna of the head and neck.

Background: Melanoma is responsible for 75% of all skin cancer-related deaths. Lentigo maligna (LM), the most prevalent melanoma in situ (MIS), accounts for 79-83% of all MIS. Its location in the head and neck area requires that tissue be spared in the course of clearing the tumor.

Congenital strangulated transmesenteric hernia: a rare cause of acute bowel obstruction.

A case of congenital transmesenteric hernia leading to intestinal obstruction is being reported here.

So near and yet so far: the specific case of Ralstonia Solanacearum populations from Côte d'Ivoire in Africa.

The genetic and phenotypic diversity of Côte d'Ivoire Ralstonia solanacearum strains was assessed on a 168-strain collection sampled on Solanaceae both in the southern lowlands and western highlands. Phylotypes I, II, and III were prevalent, though at unexpected frequencies. Phylotype I strains (87.

In vitro susceptibility of Plasmodium falciparum to monodesethylamodiaquine, quinine, mefloquine and halofantrine in Abidjan (Côte d'Ivoire).

Background: Malaria is the primary cause of hospitalization in Côte d'Ivoire. Early treatment is one of the strategies to control this illness. However, the spread of resistance of Plasmodium falciparum to antimalarial drugs can seriously compromise this strategy.

First Report of Southern Blight of Okra (Abelmoschus esculentus) Caused by Sclerotium rolfsii in Côte d'Ivoire.

Southern blight caused by Sclerotium rolfsii Sacc. was observed on okra (Abelmoschus esculentus) cv. Clemson Spineless in January 2010 during a survey of vegetable fields in Rubbino, Côte d'Ivoire, which is one of the most important areas for vegetable production.

First Report of Black Leaf Spot of Banana Caused by Deightoniella torulosa in Georgia.

Black spots were observed on the leaves of bananas (Musa spp.) grown at the University of Georgia Bamboo Farm and Coastal Gardens in Savannah, GA in November 2007. Symptoms occurred on more than 60 plants, representing 16 of 34 cultivars of bananas investigated.
