The hydrogenation of CO2 into methanol by a nickel pincer catalyst has been studied in both aqueous and solid–gas phases. Hydrogenation occurs at the moderate temperatures of 60–95 °C. The solid–gas phase reaction is found to be more efficient than the aqueous reaction. At 95 °C and 1 MPa of H2/CO2 (3:1), 18 μmol of methanol is generated in the optimized solid–gas phase reaction versus 10 μmol in

The presence of pharmaceuticals, especially antibiotics, in aquatic environments can significantly contribute to the rise of antibiotic resistance, presenting a critical global public health challenge. This study investigates the presence of four selected antibiotics and an antiretroviral drug (nevirapine) in the Vaal River in South Africa. Grab samples collected at nine sampling sites across four

Standard ZYMO DNA/RNA miniprep extraction protocol written in a user friendly way to reduce in-process-decisions and process time

Modified ZYMO DNA/RNA miniprep extraction protocol written in a user friendly way to reduce in-process-decisions and process time. Sample type is organic soil, peat, from a degraded rich fenThis protocol includes two modifications to tackle clogged filters. Samples were centrifuged for 45 seconds instead of 30 seconds in first pass through filters as 100 ul to 200 ul sample remained trapped above

Aberrant protein aggregation into amyloid fibrils is often catalyzed by interfaces. Therefore, it is important to characterize the surface activity of chaperone proteins having the ability to suppress amyloid formation. The air–water interface is of large practical significance in experimental setups used to study aggregation kinetics in vitro, but in addition, the binding of chaperones to hydroph

Breakthroughs in battery research are imperative to provide society with batteries that are safe and sustainable, have a high energy density, and have a long cycle life at low cost. Recent advances in research methodologies, the emergence of new market opportunities, and strategic funding schemes have allowed not only large, but also small companies, universities, and public research organizations

Precisely determining the oxidation states of metal cations within variable-valence transition metal oxides remains a significant challenge, yet it is crucial for understanding and predicting the properties of these technologically important materials. Iron oxides, in particular, exhibit a remarkable diversity of electronic structures due to the variable valence states of iron (Fe 2+ and Fe 3+). A

UNLABELLED: The primary objective of this study was to investigate whether ligand-receptor interactions (LRIs) between IGHG and FCGR gene products are associated with progression to type 1 diabetes (T1D). Using two completed clinical trials (DPT-1 and TN07), we applied next-generation targeted sequencing to genotype IGHG and FCGR genes in a cohort of 1,214 individuals and assessed LRI associations

Detta arbete undersöker tillväxteffekten av andelen förnybar elproduktion av den totala nationella elmixen med paneldata från 49 afrikanska länder 1996-2020, i Fixed Effects-regressioner. Förnybar energi framhålls ofta som en nyckelfaktor för hållbar utveckling, samtidigt som sambandet mellan förnybar energi och ekonomisk tillväxt är omdiskuterat i tidigare forskning. Resultaten i denna undersökni

This study investigates the effects of climate policy uncertainty (CPU) shocks on metal spot prices from 1990 to 2025 using impulse response analysis within a Vector Auto-Regressive (VAR) framework. The results indicate that price responses are time-varying and heterogeneous across metals. Overall, CPU shocks are found to have contemporaneous negative effects with short-term persistence. Although

This paper is an empirical study on the effect that different weather conditions have on electricity prices in Denmark between the 29th of April 2023 and the 29th of April 2025. The study analyses how daily time series data for wind speed, temperature and solar exposure impacts daily electricity prices in respective bidding areas. The findings of this paper concludes that each of the measured weat

We observe that, while predicting returns remain difficult and uncertain, volatility exhibit more persistence and predictability due to well-known patterns such as volatility clustering (Mandelbrot, 1967). We test whether short-horizon volatility forecasts can be used to time leverage in a passive index strategy so as to mitigate the growth penalty from volatility drag in leveraged exchange-traded

This thesis examines how heterogeneous U.S. firms respond to trade policy announcements issued by President Donald Trump during his two administrations (2017–2021 and from 2025 onward). The results imply that among the 144 firms studied, export-oriented firms were more negatively affected by the trade policy announcements chosen for this study than non-export-oriented firms. These findings are con

This thesis asks whether European Union candidacy, as an intermediate stage prior to accession, increases bilateral trade between Western Balkan candidates and EU members. The methodology combines a structural-gravity framework estimated by PPML with a heterogeneity-robust staggered difference-in-differences event study, using directional dyad–year goods trade for 2006–2019 and exporter×year, impo

This thesis investigates the impacts of three major global disruptions: the COVID-19 pandemic, the Suez Canal blockage, and the Russia-Ukraine war on Sweden’s automotive exports, a critical sector contributing approximately 15% to Sweden’s total goods exports. Utilizing monthly export data from 2017 to 2024 and employing a Seasonal Auto-Regressive Integrated Moving Average model with exogenous inp

This study investigates how different monetary policy tools have influenced deviations from Covered Interest Parity (CIP) in the USD/SEK 3-month cross-currency basis from 2007 to 2023. Using weekly data and OLS regression with Newey-West standard errors, the analysis evaluates the impact of policy-rate changes, quantitative easing (QE), and central-bank swap lines implemented by the Federal Reserv

In this text we develop a model of countries deciding on mitigation levels of CO2 in a tit-for-tat manner. Taking key ideas from earlier papers, we construct a payoff framework which describes free-riding incentives and which assesses the utility of countries' discounted future output - an output which is reduced by both abatement costs and climate damage. We then, by means of a differential e

Background: Chronic kidney disease (CKD) affects 6–10% of adults and often remains undiagnosed until advanced stages, leading to inadequate management. This study compared diagnosed, proxy-diagnosed, and undiagnosed CKD patients regarding prevalence, clinical assessment, nephroprotective treatment, healthcare utilization, and mortality. Methods: This retrospective observational study analyzed Regi
