Understanding high photocatalytic activity of the TiO2 high-pressure columbite phase by experiments and first-principles calculations
The clean production of hydrogen as a zero-emission fuel can be done using photocatalysis, with TiO2 being one of the most promising photocatalysts. However, the activity of TiO2 anatase and rutile phases is still limited. In this study, an oxygen-deficient high-pressure phase of TiO2, columbite, is stabilized by a high-pressure torsion method. The phase is utilized as an active photocatalyst for hydrogen production, and the mechanism of its high activity is examined using density functional th…

Assessing Pedestrian Behavior Around Autonomous Cleaning Robots in Public Spaces: Findings from a Field Observation
As autonomous robots become more common in public spaces, spontaneous encounters with laypersons are more frequent. For this, robots need to be equipped with communication strategies that enhance momentary transparency and reduce the probability of critical situations. Adapting these robotic strategies requires consideration of robot movements, environmental conditions, and user characteristics and states. While numerous studies have investigated the impact of distraction on pedestrians' moveme…

New study: 60% of the world’s land area is in a precarious state, putting at risk the ability of the plant world to acquire enough energy through photosynthesis to maintain the material flows of carbon, water and nitrogen that support the ecosystems.

60 percent of the world’s land area is in a precarious state
15.08.2025 – A new study maps the planetary boundary of “functional biosphere integrity” in spatial detail and over centuries. It finds that 60 percent of global land areas are now already outside the locally defined safe zone, and 38 percent are even in the high-risk zone. The study was led by the Potsdam Institute for Climate Impact Research (PIK) together with BOKU University in Vienna and published in the renowned journal One Earth.

Visible-Light Photocatalytic Degradation of Cresols using Sustainable 3D-Printed Bi4O5I2-Hematite Scaffold
In photocatalysis, the reusability limit of catalysts can contribute to secondary pollution, posing ecological risks. Addressing this, the present study explores the integration of additive manufacturing with photocatalysis by decorating Bi$_4$O$_5$I$_2$ onto a 3D-printed hematite scaffold (Bi$_4$O$_5$I$_2$@3DH) for the degradation of cresols. The 3D-printed hematite grid, fabricated via direct ink writing, exhibited excellent rheological behavior ($τγ= 24$ Pa), allowing precise shape retenti…

Hi @… - I finally got back to some Claude-coding and told it to build me some BDD tests with Pytest and it seems to have done a reasonable job. https://github.com/adrianco/the-goodi…

David Barton isn’t just a primary pitchman for the Ten Commandments law in Texas
His fingerprints appear on 28 bills that have cropped up before the legislatures in 18 states this year.
A data analysis of the bills exposes how their language, structure and requirements are inherently identical.
In dozens of instances, they match model legislation pitched by Barton verbatim.
At the Texas hearing, Barton’s eyes fixated on the cover of the rare 1782 Aitken Bible.

28 Bills, Ten Commandments and 1 Source: A Christian Right ‘Bill Mill’
More than a dozen state bills — and three new laws mandating the Ten Commandments in public schools — are virtually identical to model legislation.
