In order to engineer a band gap into graphene, covalent bond-forming reactions can be used to change the hybridization of the graphitic atoms from sp(2) to sp(3), thereby modifying the conjugation length of the delocalized carbon lattice; similar side-wall chemistry has been shown to introduce a band gap into metallic…

Thermostability of proteins in general and especially thermophilic proteins has been subject of a wide variety of studies based on theoretical and experimental investigation. Thermostability seems to be a property obtained through many minor structural modifications. In order to gain better understanding of the thermo…

Microscopy Today congratulates its first group of Innovation Award winners. The ten innovations described below move several microscopy techniques forward: light microscopy, scanning probe microscopy, electron microscopy, analytical microscopy, and specimen preparation. These innovations will make imaging and analysis…
Contrasting Awareness and Training Awareness is not the same as training. In contrast to training, awareness can occur at the same time everywhere and on a continuous basis. Information security and privacy awareness activities promote ongoing compliance and keep the issues in the minds of your personnel. Remember tha…
On page 615, the label of abscissa in Figure 8 is ‘cA’ which denotes the conversion of A groups. It should be ‘c0’ which denotes the monomer concentration. Dependence of the ratio of z-average radius of gyration, Rgz, to z-average hydrodynamic radius, Rhz, γ = Rgz/Rhz, on the monomer concentrations, c0, with the conve…

This chapter concerns the monitoring of health and safety performance, including both active measures like inspections and reactive measures like injury statistics. It is about reviewing progress to see if something better can be done and auditing to ensure that what has been planned is being implemented.
Photocatalytic glass is described in all its characteristics. Differences between plain and functionalized glass are highlighted, along with all the tasks concerning the deposition of a transparent and photoactive on glass. Optical properties, superhydrophilicity and retention of self-cleaning properties are deeply an…
The crystal structure of the title complex, [Yb(2)(C(8)H(4)O(4))(2)(C(2)O(4))(H(2)O)(2)](n), features an extended three-dimensional framework made up of Yb(3+) ions coordinated by terephthalate ligands, oxalate ligands and water mol-ecules. The Yb(3+) ion has a distorted square-anti-prismatic coordination formed by on…
The drastic changes of Fermi surfaces as well as transport anomalies near P=Pc~2.35 GPa in CeRhIn5 are explained theoretically from the viewpoint of sharp valence change of Ce. It is pointed out that the key mechanism is the interplay of magnetic order and Ce-valence fluctuations. It is shown that the antiferromagneti…

The impact of the surface on the magnetic symmetry is studied. It is shown\nhow symmetry breaking transforms the "seeding" 90 bulk magnetic classes, which\ninclude 66 piezomagnetic classes and 58 magnetoelectric classes, into the 21\nsurface-induced magnetic classes, which all are piezomagnetic, piezoelectric\nand 19…
We study all-carbon-hydrogen molecular transistors where zigzag graphene nanoribbons play the role of three metallic electrodes connected to a ring-shaped 18-annulene molecule. Using the nonequilibrium Green function formalism combined with density functional theory, recently extended to multiterminal devices, we show…
В ИТМ НАН Беларуси из разработанного экспериментального эвтектического износостойкого чугуна освоено изготовление методом литья в кокили, песчаные и комбинированные формы деталей повышенной износостойкости для агрегатов\nпо производству кирпича из глины и центробежных измельчителей.
Рассмотрено влияние структурно-высокодисперсного силуминового раскислителя-модификатора на жидкую сталь.
Проведено исследование влияния содержания меди и дисперсности микроструктуры заготовок из эвтектического антифрикционного силумина на их фрикционную износостойкость.
INTRODUCTION: Chitosan (CS) /poly(acrylic acid) (PAA) nanoparticles (NPs) have recently been obtained by template polymerization1. In this technique, the NPs are produced upon polymerization of an acrylic monomer next to the chitosan backbone. Due to the electrostatic interaction, the negatively charged acrylic monome…
