Transparent Porous Conductive Substrates for Gas-Phase Photoelectrochemical Hydrogen Production

Kevin Sivula, Jun Ho Yum, Simon Nussbaum, Rebekah Anne Wells, Marina Caroline Michèle Caretti, Hannah Elizabeth Johnson, Emeline Cécile Rideau, Benjamin Goldman, Elizaveta Potapova Mensi

Gas diffusion electrodes are essential components of common fuel and electrolysis cells but are typically made from graphitic carbon or metallic materials, which do not allow light transmittance and thus limit the development of gas-phase based photoelectr ...

The evolution of the Milky Way's thin disc radial metallicity gradient with K2 asteroseismic ages

Saniya Khan

The radial metallicity distribution of the Milky Way's disc is an important observational constraint for models of the formation and evolution of our Galaxy. It informs our understanding of the chemical enrichment of the Galactic disc and the dynamical pro ...

Engineering of PEM-PEC photocathodes for solar-driven hydrogen production

Marina Caroline Michèle Caretti

Earth has always been in perpetual evolution, but today we must face its rapid change due to human activity. The intensification of industrial activities and transportation to support our modern lifestyles are the main causes of climate change and the adve ...

Strategic factors to design the next generation of molecular water oxidation catalysts: Lesson learned from ruthenium complexes

Mohammad Khaja Nazeeruddin

Energy conversion through sustainable means is essential to counter global warming and an urgent solution through a multidisciplinary approach is required. The temperature change stems from the emission of greenhouse gases largely contributed by burning fo ...

Solar Water Splitting Using Earth-Abundant Electrocatalysts Driven by High-Efficiency Perovskite Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Dan Ren, Hong Zhang

Hydrogen is considered as the "holy grail" for the energy community. One of the most promising strategies to produce hydrogen is to split water using renewable energy such as solar radiation. The abundance of water and solar energy enables the potential of ...

The Pristine survey - XVI. The metallicity of 26 stellar streams around the Milky Way detected with the STREAMFINDER in Gaia EDR3

Pascale Jablonka, Carmela Lardo

We use the photometric metallicities provided by the panoramic Pristine survey to study the veracity and derive the metallicities of the numerous stellar streams found by the application of the STREAMFINDER algorithm to the Gaia Early Data Release 3 data. ...

Solid-state synthesis of CdFe2O4 binary catalyst for potential application in renewable hydrogen fuel generation

Michael Graetzel, Shaik Mohammed Zakeeruddin

Clean energy is highly needed at this time when the energy requirements are rapidly increasing. The observed increasing energy requirement are largely due to continued industrialization and global population explosion. The current means of energy source is ...

Thermodynamic modelling of hydrogen production in sorbent-enhanced biochar-direct chemical looping process

Zezhong Li

Hydrogen (H-2) has been widely considered the clean energy carrier of choice for emerging renewable energy generation technologies. However, H-2 is a secondary fuel mainly derived from natural gas. Over the past decades, research on developing H-2 producti ...
