Ammonia synthesis via the high-temperature and -pressure Haber-Bosch (HB) process at large centralized facilities has a significant contribution to the global CO2 emission. Radically new catalysts should be discovered to enable sustainable ammonia synthesis processes that can operate at much lower temperatures to relax the demand for the high pressure in the current HB process. In this manner, the

Emission factors from Indian electricity remain poorly characterized, despite known spatial and temporal variability. Limited publicly available emissions and generation data at sufficient detail make it difficult to understand the consequences of emissions to climate change and air pollution, potentially missing cost-effective policy designs for the world’s third largest power grid. We use reduced-form

Figure 1. Conceptual figure displaying the “Multiple in Multiple out” approach. The top panel provides a conceptual diagram of the effects of multiple stressors on multifunctionality across divergent systems. The bottom panel displays the nature of interactions across multiple stressors (in this case, only two) and their multifunctional outcomes. Francisco Dini-Andreote is an Assistant Professor in

We assessed mortality risks associated with source-specific fine particles (PM2.5) in a pooled European cohort of 323,782 participants. Cox proportional hazard models were applied to estimate mortality hazard ratios (HRs) for source-specific PM2.5 identified through a source apportionment analysis. Exposure to 2010 annual average concentrations of source-specific PM2.5 components was assessed at baseline

A strong material becomes more rigid or more relaxed when its constituent gears are spun.

A long-running La Niña climate event could persist into 2023. Plus, breast cancer cells are more likely to go rogue at night, and research to quantify and reduce inequality.

The lineages’ rise seems to stem from their ability to infect people who were immune to earlier forms of Omicron and other variants.

‘Microorganism’ is a misnomer when it comes to centimetre-long Thiomargarita magnifica.

Membranes with methane-excluding pores can remove nitrogen and carbon dioxide from natural gas in an energy-efficient and cost-effective way.

Scientists can now check whether a journal website has been cloned before submitting their manuscript.

Background Prenatal exposures to neurotoxic metals and trace elements are associated with early childhood neurodevelopmental outcomes. However, consequences of simultaneous exposure to mixtures of elements remain unclear. Objective To examine individual and joint effects of prenatal trace element exposure on early childhood neurodevelopment. Methods Using a well-established Bangladesh prospective birth

Lead is a chemical contaminant that threatens public health, and high levels of lead have been identified in drinking water at locations across the globe. Under-served populations that use private systems for drinking water supplies may be at an elevated level of risk because utilities and governing agencies are not responsible for ensuring that lead levels meet the Lead and Copper Rule at these systems

This research investigates carbon footprint impacts for full fleet electrification of Swedish passenger car travel in combination with different charging conditions, including electric road system (ERS) that enables dynamic on-road charging. The research applies a prospective life cycle analysis framework for estimating carbon footprints of vehicles, fuels, and infrastructure. The framework includes

Active chlorine species-mediated electrocatalytic oxidation is a promising strategy for ammonia removal in decentralized wastewater treatment. Flow-through electrodes (FTEs) provide an ideal platform for this strategy because of enhanced mass transport and sufficient electrochemically accessible sites. However, limited insight into spatial distribution of electrochemically accessible sites within FTEs

Dual-functional micro/nano motors that can sensitively detect and rapidly degrade organic pollutants show great application prospect in the field of environmental remediation. Here we demonstrate the first proof-of-concept of a novel self-propelled nanomachine for simultaneously colorimetric detecting and removing aquatic pollutants based on the use of ascorbic acid-functionalized NiMn-CLDHs@HNTs-Ag

Organic radical batteries (ORBs) are a promising class of electrochemical power sources employing organic radicals as redox-active groups. This article reports on the development of a versatile on-substrate electrode setup for spectroelectrochemical Electron Paramagnetic Resonance (EPR) measurements on redox conductive polymers for ORBs. Quantitative in-operando EPR experiments performed on electrochemical

African researchers have been warning about monkeypox outbreaks for years. As vaccines are deployed globally, they worry they will be left behind.

Meteorologists are forecasting a third consecutive year of La Niña. Some researchers say similar conditions could become more common as the planet warms.

The heart, the first organ to develop, undergoes complex morphogenesis that when defective results in congenital heart disease (CHD). With current therapies, more than 90% of CHD patients survive into adulthood but often suffer premature death from heart failure (HF) and non-cardiac causes 1. To gain insight into poorly understood disease progression, we performed single nuclear RNA sequencing (snRNA-seq)

There is a well-documented gap in the observed number of scientific works produced by women and men in science, with clear consequences for the retention and promotion of women in science1. The gap might be a result of productivity differences2-5, or it might be due to women’s contributions not being acknowledged6,7. This paper finds that at least part of this gap is due to the latter: women in research
