Direct high-temperature growth of GaN on Si using trimethylaluminum preflow enabling vertically-conducting heterostructures

Elison de Nazareth Matioli, Alessandro Floriduz

In this work, we demonstrate that GaN can be directly grown at high temperature on Si(111) substrates by metalorganic CVD without using any intentional AlN buffer, by simply employing a trimethylaluminum (TMAl) preflow. We found that n-GaN layers directly ...

Liquid metal infiltration of silicon based alloys into porous carbonaceous materials. Part II: Experimental verification of modelling approaches by infiltration of Si-Zr alloy into idealized microchannels

Ludger Weber, Caroline Hain, Giovanni Bianchi, Alberto Ortona, Manoj Kondibhau Naikade

In this work, the mechanisms leading to the pore closure in reactive melt infiltration (RMI) of carbon by pure silicon and a near eutectic Si-8 at-pct Zr alloy at 1500 and 1700 degrees C under vacuum were studied. Various geometrical configurations of micr ...

Al uptake in calcium silicate hydrate and the effect of alkali hydroxide

Karen Scrivener, Barbara Lothenbach, Yan Yan

The effect of Al and of pH on the structure of calcium silicate hydrate (C-S-H), the most important hydration product in Portland and blended cement, was studied at Ca/Si similar to 1.0. The presence of Al led to higher amounts of secondary phases, larger ...

Shake table testing of aggregate masonry buildings

Katrin Beyer, Igor Tomic, Andrea Penna

Masonry building aggregates can be found throughout historical city centers of Europe. Adjacent buildings have often developed during the long densification process, without consistent planning or engineering. It is common for neighboring units to share a ...

Mechanistic Study of Diaryl Ether Bond Cleavage during Palladium-Catalyzed Lignin Hydrogenolysis

Jeremy Luterbacher, Yuan Li

Hydrogenolysis has emerged as one of the most effective means of converting polymeric lignin into monoaromatic fragments of value. Reported yields may be higher than for other methods and can exceed the theoretical yields estimated from measures of the con ...

Case study of rotor lifting in a pumped storage hydropower plant in Norway

Giovanni De Cesare, Daniel Kevin Pace

The Duge pumped storage power plant in Norway currently experiences a problem with rotor-lifting. One of the two vertical 100 MW units lifts up off its bearings when operated above a certain load. The vertical forces on the units have been known to be marg ...

Séries TV et anticipation | Vision(s) du futur

Alexandre André Robert Rigal

Face aux incertitudes du futur, quel rôle jouent les séries TV que nous dévorons ? Si les séries d’anticipation sont souvent des dystopies, soit des utopies virant au cauchemar, la fiction permet également d’imaginer un futur souhaitable. Car certaines sér ...

A Short Synthesis of the 2-Bromo-N,9-dimethyl-6,7,8,9-tetrahydro-5H-pyrido[2,3-b]indol-6-amine Building Block

Andrea Pfeifer, Andreas Muhs

A concise synthesis of pharmaceutically useful (R)-tert-butyl N-(2-bromo-9-methyl-6,7,8,9-tetrahydro-5H-pyrido [2,3-b ] indol-6-yl) -N-methylcarbamate building block 11 is described. The racemic intermediate 17 was prepared in a single step from 2-bromo-6- ...
