Advanced Functional Materials, EarlyView.A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.

Prediction of the critical collapse pressure of ultra-deep water flexible risers-a: Literature review [PDF]
FME Transactions, 2018 Flexible riser is a device which transports production fluids between floating vessels and subsea wells. With fewer remaining easy-to-access oil fields nowadays, flexible risers are being required to be installed in a water depth of over 3000m.

Collapse of an initially spherical vapour cavity in the neighbourhood of a solid boundary [PDF]
, 1971 Vapour bubble collapse problems lacking spherical symmetry are solved here using a numerical method designed especially for these problems. Viscosity and compressibility in the liquid are neglected.

Advanced Functional Materials, EarlyView.Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Research on Gas Hydrate Wellbore Stability Based on D-P Criterion
Shiyou jixieDuring drilling operations,drilling fluid generates heat exchange with hydrate formation,and the invasion of drilling fluid affects the stability of the hydrate.Both situations cause changes in the stress field around the well,leading to complexities ...
