When ancient Egyptians built King Menkaure’s pyramid more than 4,000 years ago, they did it a little differently. Now archaeologists want to put it back together.
“We are 36 miles away from the fire and we can see it,” one person said, while another posted a photo of the fire’s glow from roughly 25 miles away.
The Booker Fire Department, which serves Booker, Texas, about 20 miles away from Elmwood, also responded to the fire. They posted videos of the explosion, saying it was a gas line.
Tesla detailed its capital expenditure plans for 2024 and beyond in a 10-K it released this morning.
Tesla has routinely revealed an increase in planned capital expenditures over the past few years, and 2024 seems to be no different. In a 10-K, which was released by Tesla this morning, it expects to spend at least $10 billion this year and between $8 billion and $10 billion in 2025 and 2026.
Tesla said that its near-term capex plans are difficult to predict because “the number and breadth of our core projects at any given time, and may further be impacted by uncertainties in future global market conditions.”
Prof. Polshettiwar’s group at Tata Institute of Fundamental Research (TIFR), Mumbai has developed a novel “plasmonic reduction catalyst stable in air,” defying the common instability of reduction catalysts in the presence of air. The catalyst merges platinum-doped ruthenium clusters, with “plasmonic black gold.” This black gold efficiently harvests visible light and generates numerous hot spots due to plasmonic coupling, enhancing its catalytic performance.
The team describes their work in a paper published in the journal Nature Communications.
What sets this catalyst apart is its remarkable performance in the semi-hydrogenation of acetylene, an important industrial process. In the presence of excess ethene, and using only visible light illumination without any external heating, the catalyst achieved an ethene production rate of 320 mmol g−1 h−1 with around 90% selectivity. This efficiency surpasses all known plasmonic and traditional thermal catalysts.
