Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Fossil Collection at the Zoology Museum of the University of Concepción: enhancing understanding of Chile's past biodiversity [PDF]

open access: yesBiodiversity Data Journal
The digital inventory of paleontological material stored in Chilean museums is highly relevant as it increases accessibility to information, both locally and over long distances, while reducing wear and tear on specimens caused by physical manipulation ...

Tin Oxide‐Anchored MXene Composites for Enhanced Hydrogen Evolution in Alkaline Media

open access: yesAdvanced Materials Interfaces, EarlyView.
The schematic illustrates a SnO2/MXene heterostructure for efficient hydrogen evolution. SnO2 nanoparticles are uniformly anchored on conductive MXene nanosheets, enhancing charge transfer and catalytic activity. The MXene substrate provides high electrical conductivity and abundant active sites, while SnO2 facilitates water adsorption and dissociation.

A mathematical description of fossilization

open access: yesRoyal Society Open Science
Fossils constitute an inestimable archive of past life on the Earth. However, the stochastic processes driving decay and fossilization and overwhelmingly distorting this archive, are challenging to interpret. Consequently, concepts of exceptional or poor

The last common bilaterian ancestor [PDF]

open access: yes, 2002
Many regulatory genes appear to be utilized in at least superficially similar ways in the development of particular body parts in Drosophila and in chordates.

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

open access: yesAdvanced Materials Interfaces, EarlyView.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...

Engineered Living Systems With Self‐Organizing Neural Networks: From Anatomy to Behavior and Gene Expression

open access: yesAdvanced Science, EarlyView.
Ectodermal tissue excised from Xenopus embryos self‐organizes into a three‐dimensional mucociliary organoid. Here, we generate a neural variant, termed neurobot, by implanting neural precursor cells. Neurobots develop mature neurons, adopt distinct morphologies, exhibit more complex motility, and respond differentially to neuroactive compounds. Imaging

The public perception of palaeontology in Scotland: "archaeologists dig dinosaurs" [PDF]

open access: yes, 2008
There is very little written about how palaeontology is perceived by the public. Perhaps the reason is that very few professional palaeontologists have concerned themselves with public opinion, so engrossed they are with their own speciality and not ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates
