Vesicle and micellar structures formed by mixtures of the oppositely charged surfactants cetyltrimethylammonium bromide (CTAB) and sodium octyl sulfate (SOS) with and without added sodium bromide (NaBr) have been examined by small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS) techniques. The resulting spectra have been evaluated using a Fourier transform/deconvolution tec
Entangled photons offer quantum correlations with no classical analogue. In entangled pair two-photon absorption (ETPA), absorption rate is predicted to scale linearly rather than quadratically with photon flux, promising molecular excitation at fluxes far below the classical threshold. Reported ETPA cross sections nevertheless vary widely across experiments, largely since the observable, the diff
For the 2027 State Garden Show (LGS) in Neustadt a. d. WeinstraBe, a building will be erected, using a CEM II/C-M (Q-LL) as binder containing 30 O/o calcined clay in combination with 15 O/o limestone powder and just 55 O/o clinker (incl. sulphate carrier), for the first time in Germany. The panorama bar on the Neustadt viewpoint is a single-story building in reinforced concrete construction with a
Mechanochemical activation (MCA) of phyllosilicates is one of the most promising solutions to produce reactive supplementary cementitious materials (SCMs). Several studies have already shown that MCA outperforms thermal activation (TA) in terms of reactivity when clays are low in kaolinite but rich in 2:1 phyllosilicates. Because reactivity depends on phyllosilicate type as well as content, and cl
The investigations of clinker-free model and synthetic cement systems reveal deeper insight into the behavior of metasmectite during early hydration. The use of metasmectite accelerates the aluminate clinker reaction and influences the degree of hydration of alite. Its chemical reactivity can be demonstrated in clinker-free as well as model cement systems by direct quantification of the metasmecti
Construction and demolition waste represents one of the largest waste streams in the European Union. The soil and stone fraction accounts for the biggest share of these materials. This fraction includes waste materials from tunnelling and excavations, which often contain significant amounts of clay minerals. The demand for raw materials containing clays will increase significantly due to the growi
When AI agents accessed the internet and intruded on another party’s systems during the recent OpenAI–Hugging Face incident, it was widely framed as a sign of uncontrollable agentic AI. The UN's Independent International Scientific Panel on AI (IISPAI) has now adopted this exact premise in its first Thematic Brief, treating the breach as an inflection point. The Panel discusses this primarily as a
Artificial Intelligence (AI) applications are increasingly used to support independent living and care for older adults, particularly those in vulnerable situations. Yet, how vulnerability is constructed when AI enters later-life care remains poorly theorized. Existing approaches to vulnerability in old age inadequately address AI-related risks, structural conditions, exposure pathways, and life c
At MAX IV pixelated area detectors are operated at high frame rates to take advantage of the X-ray beam properties available from the fourth generation synchrotron in scattering, diffraction and imaging applications. A variety of photon counting and charge integrating detectors and sCMOS cameras have been integrated into a common data acquisition (DAQ) system in which data are streamed to a centra
Innovation characterizes industrial, economic, and societal development. Within the domain of the built environment, technological advancements are continuously pursued to enhance structural safety, functionality, and cost efficiency. At the same time, the challenges associated with ageing infrastructure and constrained resources necessitate the systematic development and effective diffusion of te
E-commerce returns are costly yet associated with higher purchasing, creating a profitability paradox. Using archival data from a Nordic fashion retailer (2015–2022; 260,698 orders; 110,772 customers), we test an exposure-based framework with Bernoulli modeling, difference-in-differences with matched controls, and profitability threshold analysis. Returner status follows a Bernoulli exposure patte
Schima – Morphe – Ichos (SMI) is a responsive performance that combines sound, movement and sculptural objects made from steel and textiles that incorporate sensing devices. Moving the sculptures around activates the real-time transformation of sounds recorded whilst the sculptures were made based on position, orientation and movement data. Sound is directly related to the material properties of t
We investigate the challenges of enabling effective collaboration between human operators and heterogeneous autonomous agents in complex, dynamic environments by developing an interaction platform that allows study of operator behavior and supports intent inference and decision-making using state-of-the-art frameworks. We demonstrate the extent to which the operator’s perception, decisions, and ac
Partierna behöver förtydliga hur de vill driva den gröna omställningen. Ska företagen vilja investera krävs långsiktighet och tydlighet. I en krönika listar författaren tre viktiga åtgärder där partierna behöver visa sina ambitioner.
Using unique longitudinal data on individuals who resided in a mid-sized Swedish city as children (ages 1–17) from 1947 to 1967, we examined the long-term effects of experiencing family and neighborhood poverty during childhood on adult income. Poverty during childhood was calculated for the family and, using geocoded addresses, for the individualized, resident-centered neighborhood. Adult income
Societal well-being depends on the continuous operation of vital functions that critically depend on access to flows of essential commodities and services across sectors, i.e., Critical Flows. Understanding these cross-sectoral flow interdependencies requires modelling approaches capable of integrating both service and transfer interdependencies across different scales of analysis. Many existing m
Till skillnad från i Sverige har japansk robotik länge präglats av tanken på symbios mellan människa och maskin. När AI nu gör robotarna smartare kan den visionen närma sig verkligheten, skriver docent Stefan Larsson i en krönika.
