Ordered Mesoporous Graphitic Carbon/Iron Carbide Composites with High Porosity as a Sulfur Host for Li-S Batteries.

The lithium-sulfur battery (LSB) is a promising candidate for future energy storage but faces technological challenges including the low electronic conductivity of sulfur and the solubility of intermediates during cycling. Additionally, current host materials often lack sufficient conductivity and porosity to raise the sulfur loading to over 80 wt %. Here, ordered mesoporous graphitic carbon/iron carbide nanocomposites were prepared via an evaporation-induced self-assembly process using soluble resol, prehydrolyzed tetraethyl orthosilicate (TEOS), and iron(III) chloride as the carbon, silica (SiO2), and iron precursors, respectively. Graphitization and SiO2 etching were conducted simultaneously via Teflon-assisted, solid-state decomposition at high temperature. A high surface area (∼3100 m2 g-1), large pore volume (∼3.3 cm3 g-1), and graphitized carbon frame were achieved, giving a high sulfur loading (85 wt %) while tolerating volumetric expansion during discharge. Electrochemical testing of a LSB containing the composite/sulfur cathode exhibited a superior reversible capacity exceeding 1300 mAh g-1 at a moderate current (C/10) and a low decay in capacity of 9% after 500 cycles at C/5. The interaction between mesoporous graphitic carbon and sulfur is proposed.

Monodisperse mesoporous anatase beads as high performance and safer anodes for lithium ion batteries.

To achieve high efficiency lithium ion batteries (LIBs), an effective active material is important. In this regard, monodisperse mesoporous titania beads (MMTBs) featuring well interconnected nanoparticles were synthesised, and their mesoporous properties were tuned to study how these affect the electrochemical performance in LIBs. Two pore diameters of 15 and 25 nm, three bead diameters of 360, 800 and 2100 nm, and various annealing temperatures (from 300 to 650 °C) were investigated. The electrochemical results showed that while the pore size does not significantly influence the electrochemical behaviour, the specific surface area and the nanocrystal size affect the performance. Also, there is an optimum annealing temperature that enhances electron transfer across the titania bead structure. The carbon content employed in the electrode was varied, showing that the bead diameter strongly influences the minimal content of the conductive carbon required to fabricate the electrode. As a general rule, the smaller the bead diameter, the more carbon was required in the electrode. A large energy capacity and high current rate performance were achieved on the MMTBs featuring high surface area, nano-sized anatase crystals and well-sintered connections between the nanocrystals. The high stability of these mesoporous structures was demonstrated by charge/discharge cycling up to 500 cycles. Devices constructed with the MMTBs retained more than 80% of the initial capacity, indicating an excellent performance.

"Plan pantera", trauma militar en Colombia / "Panther strategy": military trauma in Colombia

Introducción. El impacto en la atención médica de los heridos en una larga guerra irregular de Colombia con la guerrilla y, más recientemente, con los narcotraficantes y las bandas criminales emergentes, originó el desarrollo de una estrategia de atención médica que garantizara un tratamiento rápido, eficaz y óptimo, con la mayor probabilidad de supervivencia del herido de guerra y una rehabilitación satisfactoria. Método. El plan estratégico de atención del trauma militar se empezó a desarrollar en el año 2000 y se implementó en el 2004 bajo el nombre de Plan Pantera. Se basó en el modelo de Haddon, conformando siete pasos sucesivos de acción y atención médica militar. Se presentan los resultados del proyecto, desde su inicio hasta el año 2010. Resultados. En el periodo comprendido entre enero del 2005 y diciembre del 2010, hubo 8.631 heridos en combate de las Fuerzas Militares de Colombia; 2.462 fueron muertos en la escena de las operaciones militares (28,5 %). Las acciones de los equipos EMEREVAC y GATRA permitieron una reducción muy significativa de la mortalidad en el campo de batalla. La mortalidad hospitalaria del último nivel de atención para pacientes con trauma mayor (ISS>15), fue de 2,3 %. Conclusiones. La estrategia de desarrollo del plan de atención médica en el paciente herido en combate, debe contemplar todas las variables que se pueden incluir dentro de un análisis de la matriz de Haddon. El Plan Pantera, como pilar de atención en las Fuerzas Militares de Colombia, ha sido exitoso y ha permitido una mayor probabilidad de supervivencia del herido en combate. Todo plan de atención médica del paciente traumatizado y críticamente enfermo, en especial en la medicina militar, debe estar fundamentado en la fortaleza de la formación continua académica y educativa de cada uno de los integrantes de los equipos de trabajo.

Background. The impact on medical care for the wounded resulting from a guerrillas and, more recently, drug trafficking and criminal gangs, long irregular warfare in Colombia originated the development of a strategy of health care oriented to ensure optimal, quick, and effective treatment seeking the most likely possibility of survival of the wounded and a satisfactory rehabilitation. Methods. The strategic military trauma care plan began to be developed in the year 2000 and was implemented in the year 2014 under the name of Panther strategy, and was based on the Haddon model that establishes seven successive steps of action and military health care. We present the results of this project, from its inception until the year 2010. Results. In the period from January 2005 to December 2010 there were 8631 combat injuries of the military forces of Colombia; 2462 were killed at the scene of the military operations (28.5%). The actions of EMEREVAC and GATRA teams resulted in a very significant reduction in mortality in the battle field. In-hospital mortality for patients with major trauma (ISS >15) at the last level of attention (Hospital Militar Central) was 2.3%. Conclusions. The strategy of developing the plan of care of patients wounded in combat should take into account all possible variables that ca be included in an analysis of the Haddon matrix. The "Panther plan" as a pillar of care in the military forces of Colombia has been successful, allowing a better chance of survival of the wounded in combat. All health care plans for the traumatized and critically ill patients, and especially in military medicine, must be based on the strength of the continuing education and academic formation of each one of the members of the teams.

An epidemic outbreak of canine cutaneous leishmaniasis in Colombia caused by Leishmania braziliensis and Leishmania panamensis.

The largest recorded outbreak of cutaneous leishmaniasis in Colombia's history occurred during 2005-2009 in soldiers of the Colombian Army, with ~40,000 cases. This outbreak was caused by the influx of military personnel into the jungle with the mission of combat illicit crops and the guerrilla. The soldiers remain for long periods within the rainforest and are exposed to the bite of infected sand flies. During the military activities, soldiers work with dogs specially trained to detect landmines, and therefore, dogs are also exposed to the infected sand flies and show high incidence of cutaneous leishmaniasis (CL). This work describes an epidemic outbreak of canine CL caused by Leishmania braziliensis and Leishmania panamensis in Colombia, South America. The clinical features of the disease and the response to treatment with pentavalent antimonials observed in 72 guard dogs from the Colombian Army are described. A program for prevention and control of canine CL is also discussed.

Efficacy of miltefosine for the treatment of American cutaneous leishmaniasis.

Miltefosine is an oral agent used for cutaneous leishmaniasis treatment. An open-label, randomized, phase III clinical trial was carried out in the Colombian army population. Miltefosine, 50 mg capsule was taken orally three times per day for 28 days (N = 145) or meglumine antimoniate, 20 mg/kg body weight per day for 20 days by intramuscular injection (N = 143). The efficacy of miltefosine by protocol was 69.8% (85/122 patients) and 58.6% (85/145 patients) by intention to treat. For meglumine antimoniate, the efficacy by protocol was 85.1% (103/121 patients) and 72% (103/143 patients) by intention to treat. No association was found between drug efficacy and L. (V.) braziliensis or L. (V.) panamensis species of Leishmania responsible for infection. Adverse gastrointestinal events were associated with the use of miltefosine, the meglumine antimoniate treatment was associated with adverse effects on the skeletal musculature, fever, cephalea, and higher toxicity in kidney, liver, pancreas, and hematological system.
