<P>A preliminary study of the behavior of lithium-ion-air battery where the common, unsafe lithium metal anode is replaced by a lithiated silicon–carbon composite, is reported. The results, based on X-ray diffraction and galvanostatic charge–discharge analyses, demonstrate the basic reversibility of the electrochemical process of the battery that can be promisingly cycled with a rather high specific capacity.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2012/nalefd.2012.12.issue-11/nl303087j/production/images/medium/nl-2012-03087j_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl303087j'>ACS Electronic Supporting Info</A></P>

A taxonomic study was recently carried out on species of the tribe Ceramieae (Ceramiaceae, Rhodophyta), following an evaluation of previously published records and on the basis of field and laboratory investigations. In Morocco, the tribe is represented by 5 genera: Ceramium (21 taxa at specific and infraspecific levels), Gayliella (3 species), and by one species each of Centroceras, Corallophila and Microcladia. Among these, there are five new records for Morocco: Centroceras gasparrinii, Ceramium botryocarpum, Ceramium cingulatum, Ceramium echionotum var. mediterraneum, and Gayliella taylorii. The report of C. echionotum var. mediterraneum from the Atlantic coast of Morocco is one of the rare records from outside the Mediterranean. Ceramium ciliatum var. robustum and Ceramium codii are recorded for the first time from the Atlantic coast of Morocco. Centroceras clavulatum is excluded from Moroccan flora having been misidentified for C. gasparrinii. This paper summarizes the taxonomic characters of these species with images and presents a key for their identification. This report is the first detailed record of the species of the tribe Ceramieae for Morocco. As a result, the total number of taxa at both specific and infraspecific levels accepted in the tribe Ceramieae for Morocco, under current taxonomy and nomenclature, is 27.

Lithium‐Sulfur Batteries: An Advanced Lithium‐Sulfur Battery (Adv. Funct. Mater. 8/2013)
Kim, Junghoon,Lee, Dong‐,Ju,Jung, Hun‐,Gi,Sun, Yang‐,Kook,Hassoun, Jusef,Scrosati, Bruno WILEY‐VCH Verlag 2013 Advanced functional materials Vol.23 No.8
<P>On page 1076, Yang‐Kook Sun, Jusef Hassoun, Bruno Scrosati, and co‐workers report and characterize a hard carbon spherules‐sulfur electrode that is prepared by impregnation of crystalline sulfur into the carbon spheres through melting and thermal treatment. This material demonstrates very high capacity and rate capability, and is therefore proposed as a new generation cathode to drive electric vehicles over a long range. </P>

<P><B>Abstract</B></P><P>We report a new sodium‐ion battery formed by coupling a NaFePO<SUB>4</SUB> cathode and a nanocomposite tin–carbon (Sn–C) sodium‐alloying anode. The NaFePO<SUB>4</SUB> cathode is obtained by Li–Na conversion of a LiFePO<SUB>4</SUB> cathode directly in the full cell employing the Sn–C anode and a sodium‐ion electrolyte. The results show that the unique approach adopted here is capable of successfully and efficiently converting LiFePO<SUB>4</SUB> into NaFePO<SUB>4</SUB> in a sodium‐ion battery operating at a voltage of 3 V, with a maximum reversible capacity of 150 mAh g<SUP>−1</SUP>, high reversibility, and high rate capability.</P>

<P>In this paper, we report a lithium-ion battery employing a lithium sulfide cathode and a silicon-based anode. The high capacity of the silicon anode and the high efficiency and cycling rate of the lithium sulfide cathode allowed optimal full cell balance. We show in fact that the battery operates with a very stable capacity of about 280 mAh g<SUP>–1</SUP> at an average voltage of 1.4 V. To the best of our knowledge, this battery is one of the rare examples of lithium-metal-free sulfur battery. Considering the high theoretical capacity of the employed electrodes, we believe that the battery here reported may be of potential interest as high-energy, safe, and low-cost power source for electric vehicles.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/aamick/2014/aamick.2014.6.issue-14/am4057166/production/images/medium/am-2013-057166_0007.gif'></P>

A 67-year-old male presented with dyspnea for which lung scintigraphy was ordered to rule out pulmonary embolus. Planar images demonstrated abnormal midline uptake of Tc-99m macroaggregated albumin, which SPECT/CT localized to several thoracic vertebrae. Thoracic vertebral uptake on perfusion lung scintigraphy was previously described on planar imaging. Radionuclide venography and contrast-enhanced CT subsequently demonstrated superior vena cava (SVC) obstruction with collateralization through the azygous/hemiazygous system and vertebral venous plexus. SPECT/CT differentiated residual esophageal/tracheal ventilation activity, a clinically insignificant finding, from vertebral uptake indicative of SVC obstruction, a potentially life-threatening condition.
An Advanced Lithium–Air Battery Exploiting an Ionic Liquid-Based Electrolyte
Elia, G. A.,Hassoun, J.,Kwak, W.-J.,Sun, Y.-K.,Scrosati, B.,Mueller, F.,Bresser, D.,Passerini, S.,Oberhumer, P.,Tsiouvaras, N.,Reiter, J. American Chemical Society 2014 NANO LETTERS Vol.14 No.11
<P>A novel lithium–oxygen battery exploiting PYR<SUB>14</SUB>TFSI–LiTFSI as ionic liquid-based electrolyte medium is reported. The Li/PYR<SUB>14</SUB>TFSI–LiTFSI/O<SUB>2</SUB> battery was fully characterized by electrochemical impedance spectroscopy, capacity-limited cycling, field emission scanning electron microscopy, high-resolution transmission electron microscopy, and X-ray photoelectron spectroscopy. The results of this extensive study demonstrate that this new Li/O<SUB>2</SUB> cell is characterized by a stable electrode–electrolyte interface and a highly reversible charge–discharge cycling behavior. Most remarkably, the charge process (oxygen oxidation reaction) is characterized by a very low overvoltage, enhancing the energy efficiency to 82%, thus, addressing one of the most critical issues preventing the practical application of lithium–oxygen batteries.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2014/nalefd.2014.14.issue-11/nl5031985/production/images/medium/nl-2014-031985_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl5031985'>ACS Electronic Supporting Info</A></P>
An improved high-performance lithium??air battery
Jung, Hun-Gi,Hassoun, Jusef,Park, Jin-Bum,Sun, Yang-Kook,Scrosati, Bruno Nature Publishing Group, a division of Macmillan P 2012 Nature chemistry Vol.4 No.7
Although dominating the consumer electronics markets as the power source of choice for popular portable devices, the common lithium battery is not yet suited for use in sustainable electrified road transport. The development of advanced, higher-energy lithium batteries is essential in the rapid establishment of the electric car market. Owing to its exceptionally high energy potentiality, the lithium??air battery is a very appealing candidate for fulfilling this role. However, the performance of such batteries has been limited to only a few charge??discharge cycles with low rate capability. Here, by choosing a suitable stable electrolyte and appropriate cell design, we demonstrate a lithium??air battery capable of operating over many cycles with capacity and rate values as high as 5,000?mAh?g<SUB>carbon</SUB><SUP>??1</SUP> and 3?A?g<SUB>carbon</SUB><SUP>??1</SUP>, respectively. For this battery we estimate an energy density value that is much higher than those offered by the currently available lithium-ion battery technology.
