Currently there is an intensive search for new materials with tuned properties for use in organic solar cells to obtain an increase in its conversion efficiency and replace silicon devices. The polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7) is a polymer recently proposed in the literature and with very interes…

Human activities generate qualitative and quantitative impacts of water resources which vary in intensity with the occupation and urbanization of a watershed, create a big problem due to the high concentration of nutrients. The nutrients released into waterways, when they exceed the limit self-purification of water re…
A problemática do combate ao mosquito Aedes aegypti, transmissor do vírus da dengue, dentre outras doenças, persiste no Brasil como um todo. Para esse combate sempre se utilizou pesticidas químicos, e o principal deles é o temefós, utilizados no controle das larvas. A partir do ano de 2000, duas preocupações passaram…
Daily rhythm of insecticide susceptibility in the silkworm Bombyx moriThe present study investigated daily changes in susceptibility to insecticides in the silkworm Bombyx mori (Lepidoptera: Bombycidae).The daily rhythm of permethrin susceptibility in fifth instar larvae of the p63 silkworm strain was significant, wit…
Malgré les propriétés remarquables de polyéthylène de masse molaire très élevée(UHMWPE), une généralisation de son application est limitée en raison des difficultésrencontrées lors de sa mise en forme, liées au taux d’enchevêtrement important deschaînes.Le but de ce travail est de développer des nanocomposites et des…
Cette thèse décrit la réalisation d’un nanocalorimètre dynamique différentiel pour l’étude de la transition vitreuse. Le capteur microfabriqué, la chaine de mesure de bas niveau de bruit et de grande stabilité, ainsi que l’environnement thermique du capteur sont décrits en détails. La méthode de mesure utilisée est un…
We would like to comment that the prediction of Half-mtallicity in only B edge H-passivated zigzag boron nitride nanoribbons (ZBNNR-BH), by Zheng et al.1, is not correct as their interpretation is erroneous. Since it is well known that for a material, to be a half-metal, as a primary condition one type of spin channel…
In this work, we introduce two new subclasses S_{{\Sigma}_{m}}({\alpha},{\lambda}) and S_{{\Sigma}_{m}}(\b{eta},{\lambda}) of {\Sigma}_{m} consisting of analytic and m-fold symmetric bi-univalent functions in the open unit disk U. Furthermore, for functions in each of the subclasses introduced in this paper, we obtain…
Semiconductor-based quantum dot single-electron pumps are currently the most\npromising candidates for the direct realization of the emerging quantum\nstandard of the ampere in the International System of Units. Here, we discuss a\nsilicon quantum dot single-electron pump with radio frequency control over the\ntranspa…
Nanotechnology is an emerging technology which has wide applications in many fields. The major objective of the study is to synthesise copper nanoparticles and its composites and to determine their antibacterial activity. A filter based on the developed material was fabricated. Copper nanoparticles were synthesised by…
Multipod-like clusters composed of a silica core and PS satellites are prepared according to a seeded-growth emulsion polymerization of styrene in the presence of size-monodisperse silica particles previously surface-modified with methacryloxymethyltriethoxysilane. Tuning the diameter and concentration of the silica s…

A Fullerene Working Party [composed of workers active in the field: Dr. F. Wudl (Chairman), Dr. R.E. Smalley, Prof. A.B. Smith III, Dr. R. Taylor, Dr. E. Wasserman – Mr. E.W. Godly (Observer)] met in Boston in February, 1993, and a set of recommendations was taken forward to the IUPAC Meeting held in Lisbon, August 19…

The involvement of multiple parties makes diplomacy indispensable to the elimination of nuclear, chemical, biological and other unconventional weapons and related materials. Diplomacy is required in any attempt to address the problems of indirect control of WMD, conflicting objectives between states, conflicting prior…
Bluestocking circle&s; designates the mid-eighteenth-century group of men and women around Elizabeth Montagu and her close friends, &s;Bluestocking&s; a woman member or associate of that circle, and &s;Bluestocking&s; a woman regarded or regardable as an intellectual or artist in that and following generations, to the…
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
I have funding available for an excellent graduate student starting between May and September 2016. The project will focus on the numerical study of atomistic mechanisms associated with aging in steels. Many macroscopic properties of the materials that surround us depend on the precise position of atoms, at the micros…
