Boosting the sensitivity of solid-state gas sensors by incorporating nanostructured materials as the active sensing element can be complicated by interfacial effects. Interfaces at nanoparticles, grains, or contacts may result in nonlinear current–voltage response, high electrical resistance, and ultimately, electric noise that limits the sensor read-out. This work reports the possibility to prepa

We are at a time when international law and the law of war are particularly important. The testing of nuclear weapons that is being used in the rhetoric surrounding threats of war is creating new fears and heightening current tensions. Richard Falk has for decades been an outspoken authority calling for nuclear disarmament and the enforcement of non-proliferation treaties. In this collection of es

This study aims to develop a framework for reshoring research, specifying the aspects encompassing a full case description. The article reports an analysis of existing case-based research focusing on manufacturing reshoring and the previous offshoring events, with the aim to advance the knowledge within the field through an accumulation process. The selected methodology to achieve this purpose is

The inertia of many power systems is expected to decrease as more wind and solar power is introduced. With low inertia, a need to estimate it arises. The estimation method should preferably work during normal operation, in order to ensure that the grid frequency can be maintained during any sudden disturbance. This study proposes a new method for inertia estimation, based on electromechanical mode

Importance: Aortic stenosis (AS) has no approved medical treatment. Identifying etiological pathways for AS could identify pharmacological targets. Objective: To identify novel genetic loci and pathways associated with AS. Design, Setting, and Participants: This genome-wide association study used a case-control design to evaluate 44703 participants (3469 cases of AS) of self-reported European ance

Objective: To explore experiences with supervised group exercise during pregnancy in women with depression or low psychological well-being. Design: A qualitative descriptive study based on semi-structured, individual, in-depth interviews analyzed by means of thematic analysis. Setting: The Department of Obstetrics, Rigshospitalet, Copenhagen University Hospital, Denmark. Participants: Through a pu

The financial crisis started in 2007–2008, initially in the US, but its consequences have been felt throughout the global economy. However, its effects were far from uniform. While parts of Asia and Africa continued to grow fast, Europe experienced a large set back. This paper emphasizes three important factors: differences across countries in technological development; differences in capacities t

The photocatalytic performance of two-dimensional materials is largely limited by the fast recombination of photogenerated charges. Herein, we design and fabricate a novel g-C3N4/BO0.2N0.8 van der Waals heterostructure to realize oriented charge flow in-plane and separation within the interface. On one hand, a B-C bond forms within the g-C3N4/BO0.2N0.8 interface after the introduction of O atoms.

Pregnancy increases the risk of pulmonary embolism. Computed tomography pulmonary angiography (CTPA) is used for diagnosis. CT generates ionising radiation, and thus, abdominal shielding may be used. This phantom study investigated the effects of patient shielding and scan length reduction on the fetal and maternal ionising radiation dose from CTPA. The absorbed dose to the fetus was measured usin

Human exposure to carbamates and organophosphates poses a serious threat to society and current pharmacological treatment is solely targeting the compounds' inhibitory effect on acetylcholinesterase. This toxicological pathway, responsible for acute symptom presentation, can be counteracted with currently available therapies such as atropine and oximes. However, there is still significant long-ter

Aim: Extrauterine growth restriction is common among extremely preterm infants. We explored whether intake of unpasteurised maternal milk (MM) and pasteurised donor milk (DM) was associated with longitudinal growth outcomes and neonatal morbidities in extremely preterm infants. Methods: Observational study of 90 preterm infants born between 2013 and 2015 in Gothenburg, Sweden. Data were prospectiv

Alzheimer's disease is the most common cause of dementia. As many as 250,000 people in Sweden will have a dementia disease in 2050. The »amyloid cascade hypothesis« is a common model which explains how β-amyloid affects the function of the nerve cells. Alzheimer's disease has a long-lasting course and can present in typical and atypical forms. CSF analyses for »core AD CSF biomarkers« and synaptic

We demonstrate a novel dispersion-scan (d-scan) scheme for single-shot temporal characterization of ultrashort laser pulses. The novelty of this method relies on the use of a highly dispersive crystal featuring antiparallel nonlinear domains with a random distribution and size. This crystal, capable of generating a transverse second-harmonic signal, acts simultaneously as the dispersive element an

Here we present the field induced self-assembly of anisotropic colloidal particles whose shape resembles peanuts. Being made up of hematite core and silica shell, these particles align in a direction perpendicular to the applied external magnetic field. Using small-angle X-ray scattering with microradian resolution (μrad-SAXS) in sedimented samples, we have found that one can tune the self-assembl
