From Photoalignment to Structured Light: Liquid Crystal Platforms for Beam Shaping and Complex Wavefronts

open access: yesAdvanced Functional Materials, EarlyView.
Photoaligned and photopatterned liquid crystal platforms provide programmable control of optical phase, polarization, and spin‐orbit interactions, enabling compact generation of structured light and complex wavefronts. This review highlights how tailored molecular orientations transform simple beams into designed optical fields, opening versatile ...

Plastics in the Earth system

Science, 2021
Plastic contamination of the environment is a global problem whose magnitude justifies the consideration of plastics as emergent geomaterials with chemistries not previously seen in Earth’s history. At the elemental level, plastics are predominantly carbon.

The earth system

Future Generation Computer Systems, 1989
Abstract The ozone hole and greenhouse warming are but examples of changes taking place in our global environment at an unprecedented rate — changes that will have profound implications for our children and grandchildren. They present to the scientists of the world a tremendous challenge: to develop an understanding of the underlying interactions ...

Earth System Science

Science, 2001
O ne of the great scientific challenges of the 21st century is to forecast the future of planet Earth. As human activities push atmospheric carbon dioxide (CO2) and methane concentrations far beyond anything seen for nearly half a million years (prompting the strongest statement yet from the Intergovernmental Panel on Climate Change that human ...

A dynamic earth observation system

Parallel Computing, 2003
The paper presents an overview of SARA/Digital Puglia (Synthetic Aperture Radar Atlas), a remote sensing environment that shows how grid technologies and high performance computing can be efficiently used to build dynamic earth observation systems for the management of huge quantities of data coming from space missions and for their on-demand ...

Genealogies of Earth System thinking

Nature Reviews Earth & Environment, 2020
In the first half of the 20th century, the Earth was already envisioned as a system of interacting parts intertwined with human cultural evolution. Historical sources of Earth Systems thinking can still be relevant in light of current and future trajectories, and may offer insights to inform and rethink present-day discourses and strategies.
