In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Towards carbon neutrality of calcium carbide-based acetylene production with sustainable biomass resources

open access: yesGreen Energy & Environment
Acetylene is produced from the reaction between calcium carbide (CaC2) and water, while the production of CaC2 generates significant amount of carbon dioxide not only because it is an energy-intensive process but also the raw material for CaC2 synthesis ...

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...

The Liberation of Formaldehyde Through the Agency of Calcium Carbide

open access: yesJournal of Infectious Diseases, 1907
During the last two years a very considerable amount of work has been done at the Maine Laboratory of Hygiene upon the matter of formaldehyde disinfection. In the course of this work the formalinpermanganate method was first worked out as a means of practical disinfection. In one way this method seemed an anomaly, in that part of the agent which was to
