In this present work, different supports (CeO2/ZrO2) and different Ni contents based catalysts were prepared by incipient wetness impregnation method and tested in the methane steam reforming (MSR) reaction. The prepared catalysts were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The XRD analysis confirmed the prepared Ni/CeO2 samples have a pure crystal structu
We have modified the popular MM/PBSA or MM/GBSA approaches (molecular mechanics for a biomolecule, combined with a Poisson-Boltzmann or generalized Born electrostatic and surface area nonelectrostatic solvation energy) by employing instead the statistical-mechanical, three-dimensional molecular theory of solvation (also known as 3D reference interaction site model, or 3D-RISM-KH) coupled with mole
We describe the detectors for identification of charged particles and fragments in CHICSi, a large solid angle multitelescope system mounted inside an ultra-high vacuum (UHV), cluster-jet target chamber. CHICSi performs nuclear reaction experiments at storage rings. The telescopes consist of a first very thin, 10-14 mum Si detector, a second 300 mum (or possibly 500 pm) ion implanted Si detector s

Air pollution in the form of airborne particles – aerosols – is today an important aspect of many of our major societal challenges, such as sustainable cities, healthy indoor and working environments, clean energy production and reduced climate impact. As researchers in this field, we carry out both laboratory and field studies using measurement techniques ranging from small simple sensors to adva

Anion exchange membranes (AEMs) carrying N-spirocyclic quaternary ammonium cations generally have a high alkaline stability because the unstrained ring conformations of this type of bicyclic cation. Here, we have prepared a series of N-spirocyclic quaternary ammonium ionenes (spiro-ionenes) using a diphenyl-functionalized monomer with a di-N-spiro-isoindolium moiety containing two N-spiro cations.
One of the biggest obstacles to economic profitability of solar water heating systems is the investment cost. Retrofitting existing domestic hot water heaters when a new solar hot water system is installed can reduce both the installation and material costs. In this study, retrofitting existing water heaters for solar water heating systems in Swedish single-family houses was theoretically investig
Micro-droplets with excellent physical properties and size effects are widely used in different fields. Peristaltic pumps are often used for droplet generation. The thrust force of pumps is periodic as a periodic disturbance when the time scale is short enough. Numerical simulation based on a validated model was applied to study the periodic disturbance effects on droplet generation in a cross-jun
One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where ve
At the 3 GeV ring of the MAX IV Laboratory, a fourth-generation ring-based synchrotron light source, an asymmetric influence of the sign of the amplitude-dependent tune shift (ADTS) on the transverse mode-coupling instability has been observed. Measurements of the instability, in dedicated single-bunch experiments at low chromaticity, revealed a significant dependence of the dynamics of the instab
Novel micro-scale reaction devices are progressing in various applications. Whereas, specialized gas-producing reactors of high conversion at micro/mini scale remain challenging and are rarely explored, but are needed urgently in new generation vehicles and aerospace applications. In this work, two kinds of high-aspect-ratio flat channel (200 μm depth, 5.0 mm width, and 40.0 mm length) microreacto
The limited tolerance of Saccharomyces cerevisiae to the inhibitors present in lignocellulosic hydrolysates is a major challenge in second-generation bioethanol production. Short-term adaptation of the yeast to lignocellulosic hydrolysates during cell propagation has been shown to improve its tolerance, and thus its performance in lignocellulose fermentation. The aim of this study was to investiga

Hematopoietic cells have secretory lysosomes that degranulate at the inflammatory site upon stimulation. We asked whether one could target exogenous proteins with a therapeutic potential to secretory lysosomes in hematopoietic cells. For this purpose, we expressed a soluble tumor necrosis factor (TNF) receptor form (sTNFR1) in hematopoietic cell lines. In order to accomplish targeting to secretory
Abstract in UndeterminedIn today's technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Simulations are done in a typical 130 nm technology. Based on the simulation results, the static power in
