Oil and natural gas reserve prices, 1982-2002 : implications for depletion and investment cost [PDF]
, 2003 A time series is estimated of in-ground prices - as distinct from wellhead prices ₆ of US oil and natural gas reserves for the period 1982-2002, using market purchase and sale transaction information. The prices are a measure of the unit investment cost (

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Analysis of API 5C3 failure prediction formulae for casing and tubing [PDF]
, 2012 Due to the increasing demand for oil and gas, coupled with the fact that oil reserves are becoming rather scarce, the petroleum industry is pushed to drill and complete deeper wells. Threaded connections are often the weakest link in this process and are

Advanced Functional Materials, EarlyView.A regenerated cellulose/MXene aerogel film is engineered with a surface‐confined, coral‐like polyaniline skin to intensify interfacial polarization while a porous, percolated conductive core is retained. By molten salt hydrate processing and interfacially confined oxidative polymerization, PANI growth is localized at the outer surface and internal ...

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels
Advanced Healthcare Materials, EarlyView.We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess
