An expanding list of reliable paleomagnetic poles for Precambrian tectonic reconstructions
- 2021

Bokkapitel (refereegranskat)abstract
- We present a compilation of reliable Precambrian paleomagnetic poles from three successive international workshops (in years 2009, 2014, 2017), comprising paleomagnetists specializing in Precambrian tectonic reconstructions. The working groups compiled lists of two global classes of poles, published through the end of 2017. “Grade-A” results are judged to provide essential constraints on tectonic reconstructions; “Grade-B” poles are judged to be suggestive of high-quality, but not yet demonstrated to be primary, or perhaps lacking precise geochronologic or other constraints. Our catalog documents a resurgence of high-quality data acquisition in recent years, and highlights specific cratons and time intervals that are most lacking in the data needed to reconstruct those blocks through supercontinental cycles.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Solar Fuels and chemicals from CO2 can be produced through two main reactions: one is CO2 photoreduction, using different catalysts and different reducing agents; the other is CO2 fixation, which is usually performed through natural photosynthesis. The research nowadays is directed on the production of fuels and chemicals with one or two atoms of carbon, for example CH4, CO, HCOOH, HCHO, CH3OH, C2H5OH, etc. The chapter aims at comparing natural photosynthesis processes and reactions with artificial photosynthesis. After taking into consideration the natural photosynthetic process, the chapter focuses on heterogeneous and homogeneous photocatalysis. Heterogeneous catalysis can be performed with semiconductors and powder catalysts. Special attention is given to TiO2 as a promising photocatalyst. Homogeneous photocatalysts are usually represented by molecular catalysts, which are dissolved in water or another solvent. Usually, homogeneous photocatalysis is performed in complex systems which are composed by: a light harvesting unit (LHU) (i.e. the photosensitizer); one catalytic site for the oxidation process, where the electrons are supplied by a sacrificial donor; one reduction site, where the electrons are transmitted to CO2. Finally, even more complex systems are represented by those based on photoelectrocatalysis. These have the main advantage to separate the oxidation and reduction reactions at the two different electrodes of the system. In principle photoelectrochemical cells can be a way to mimic artificially the working principle of natural photosynthesis.

Clinical Research with Advanced Diffusion Encoding Methods in MRI
- 2020
-
Ingår i: Advanced Diffusion Encoding Methods in MRI. - Cambridge : Royal Society of Chemistry. - 2044-253X .- 2044-2548. ; 2020-January:24, s. 406-429

Bokkapitel (refereegranskat)abstract
- This chapter offers a comprehensive summary of applications of advanced diffusion encoding methods in MRI within a narrowly defined area of in vivo human measurements with imaging read-out and voxel-by-voxel data analysis. The list of methods comprises tensor-valued encoding to investigate cell densities, shapes, and orientations in heterogeneous tissues, time/frequency-dependent encoding for estimating structural length scales, adjustable velocity-encoding to monitor flow in the microcapillary network, double encoding with varying mixing times to assess diffusional exchange between distinct tissue microenvironments and across cell membranes, and relaxation-diffusion correlation to resolve and separately characterize tissue microenvironments in terms of their local chemical composition and microstructure. The shown examples include proof-of-concept measurements on healthy volunteers, pilot investigations of pathologies, and clinical research involving 10-100 subjects. Studied organs include brain, breast, prostate, liver, kidney, placenta, muscle, and peripheral nerve, with examples of pathologies from tumors, schizophrenia, multiple sclerosis, stroke, neurocysticercosis, pre-eclampsia, and chronic exertional compartment syndrome.

- Personalized and pervasive healthcare devices help seamlessly integrate healthcareand wellness into the daily life, independent of time and space. Silicon IntegratedCircuit (IC) has been used in many advanced healthcare applications due to thecompact size and ultra-low power consumption. Meanwhile, printed electronics(PE) is considered as a promising approach enabling cost-effective manufacturingof thin, flexible, and light-weight devices. A hybrid integration of IC and PE providesa new solution for the future wearable healthcare devices. In this chapter, firstlya customized bio-sensing IC is demonstrated, which can detect and process variousbio-signals; secondly, the feasibility and performance of using inkjet printingtechnology as enabling technology has been examined for the fabrication of flexiblebio-sensing devices. Finally, a wearable and flexible Bio-Patch is presented byleveraging hybrid integration of PE and bio-sensing IC. In-vivo test results showthat the flexible Bio-Patch provides high quality ECG signal comparable with theone gained by bedside ECG machine.
