Eco‐Efficient Processing and Refining Routes for Secondary Raw Materials from Silicon Ingot and Wafer Manufacturing

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The ICARUS project developed pilot‐scale processes to recover and refine secondary raw materials from silicon photovoltaic (PV) ingot and wafer manufacturing waste. Silicon kerf, graphite, and silica residues are purified into high‐value inputs for the PV value chain and beyond.

Sprouting of Yam Bulbils as Affected by Chemical Treatment

open access: yesDavao Research Journal, 1999
The sprouting of yam (Dioscorea alata cv. Baligun-on) bulbils treated with ethephon (up to 10,000 ppm) and calcium carbide (up to 100,000 ppm) was neither hastened nor delayed.

Beyond Acetylene: Exploring Solvent Stabilization of Calcium Carbide‐derived Acetylide Intermediates and Their Significance in Small Organic Molecule Synthesis

open access: yesChemistrySelect
The reaction of calcium carbide with water has been widely used as a source of acetylene for the synthesis of organic molecules. In contrast with this traditional approach, we use the CaC2 reaction under water‐starved conditions and show reactions that ...

Upsampling DINOv2 Features for Unsupervised Vision Tasks and Weakly Supervised Materials Segmentation

open access: yesAdvanced Intelligent Systems, EarlyView.
Feature from recent image foundation models (DINOv2) are useful for vision tasks (segmentation, object localization) with little or no human input. Once upsampled, they can be used for weakly supervised micrograph segmentation, achieving strong results when compared to classical features (blurs, edge detection) across a range of material systems.
