Protein cages are hollow containers typically made from multiple copies of a small number of protein subunits. They occur extensively in nature and morphologies can vary but typically they are close to spherical in shape and have diameters in the nanometers to tens of nanometers range. Because central cavities of prot…
Many metallic heritage objects, including lead, are in open display cases in museums, where the environment cannot be fully controlled.Temperature and humidity fluctuations often cause these objects to experience cyclic wet and dry periods and to suffer atmospheric corrosion 1
With this study, we describe a method for electropolymerizing a PEDOT:Perchlorate polymer onto the surface of platinum disk microelectrodes. Using cyclic voltammetry as an electropolymerization technique, we deposit an approximately 13 ± 1 µm thick coating of the polymeric material that enhances the electron transfer…
As is known, the constraints (strength conditions) for the safety factor of elastic structures and design details of a particular class, e.g. aviation structures are established, i.e. the safety factor values of such structures should be within the given range. It should be noted that the constraints are set for the s…
In the current work, a series hybrid vehicle has been constructed that utilises a dual-fuel, reactivity controlled compression ignition (RCCI) engine. Full vehicle testing was conducted on chassis dynamometers over the US Environmental Protection Agency Federal Test Procedure, Highway Fuel Economy Test and US06 using…
This Doctoral Thesis focuses on the preparation by various methods of soft chemistry of several series of Cobalt mixed oxides with general formula Lnl -xMxCoO3 (Ln= La, Pr, Nd, Gd; M= Ca, Ba, Sr; 0 < x < 0.50) and perovskite structure; in their structural and morphological characterization; and in the systematic searc…
Crystal structure analysis is a standard technique routinely applied to single crystals as well as powders. However the process is not so straightforward if the crystal sample is affected by twinning or if the structure is modulated. In such cases the standard procedures are not directly applicable. The main purpose o…
Colombian areas (white beach in Santa Marta, Cartagena, Sierra Nevada de Santa Marta, Chicamochas Canyon Santander and near Villa de Leyva Boyaca), in a particular group of samples (Chicamochas Canyon Santander), was detected Ru, by XRF a rare element in nature, but even more uncommon in this area.
有明海におけるタイラギの分布には，着底期における浮泥の存在が影響すると報告されている．本研究は，数値シミュレーションによって過去の浮泥分布を推定し，当時のタイラギ着底稚貝分布と比較することで浮泥の影響を定量的に検討した． 用いた数値シミュレーションモデルはマッピングされた含水比を入力条件とし，巻き上げ係数の空間分布を加味して計算を行う既報のモデルで，新たに含水比の時間変化についても簡易的に予測する改良を行った．本モデルは有明海湾奥部のSS濃度の経時変化を的確に再現するとともに，観測された浮泥厚の分布を計算結果から概ね推定することができた．浮泥厚が11mm以上の地点では着底稚貝が存在していないという結果が得られ，浮泥厚がタイラギ幼生…

Polyhydroxyalkanoates (PHAs) are microbial storage polymers accumulated by many different prokaryotes as an intracellular carbon and energy reserve. The polymer properties make PHA interesting as bioplastic. Moreover, the monomers could serve as chiral building blocks or be used as a biofuel. Currently, PHA is commerc…
Sheets from ferritic steel 3 mm thick with increased strength after thermal hardening were studied by use of various X-ray methods and mechanical testing. Rolling of steel was carried out at 1100°C with rather great reductions per pass, so that plastic deformation of metal spread by the significant distance from the s…
The integration of conducting and semiconducting architectures within thermally drawn thin and flexible fibers is emerging as a versatile platform for smart sensors and imaging systems, medical and biological probes, energy harvesting and advanced textile. Thus far however, fundamental aspects of the microstructure fo…

Bulk photovoltaic (BPV) effect has attracted more interest owing to the potential to simplify photovoltaic device structures. Herein, we demonstrate that strained Bi2Te3 films exhibit prominent BPV effect, which extends response wavelength to the infrared.

В рамках теории функционала электронной плотности с градиентным обменно-корреляционным функционалом в форме Perdew--Becke--Ernzerhof и его гибридной версией с вкладом обмена по Хартри-Фоку 25% в базисе локализованных атомных орбиталей проведено первопринципное исследование кристаллического строения, химической связи,…
This paper presents part of the activity carried out by Politecnico di Torino and Fiat Research Center within the CORE project. The work focused on one hand on the use of innovative fuels in heavy-duty (HD) vehicles, on the other hand on increasing the engine efficiency. The adoption of variable valve actuation device…
Control of crystal growth is important in various scientific or industrial processes such as purification, crystalline devises, X-ray crystallography, and so on. Most of studies have focused so far to the control of crystal growth by adjusting environmental parameters such as additive, solvent, and temperature. On the…
SiO2 nanocolumns as spacers are introduced into plasmonic antireflective structure by oblique angle deposition. The deposition angles determine the morphology of SiO2 and the size distributions of Ag particles, which results in different reflections.
