Oxygen diffusion kinetics, buffering capacity and phenotype: A narrative review of oxygen physiology and later phenotype in very preterm infants. [PDF]

Exp Physiol
Abstract Clinicians often view exposure to supplementary oxygen in preterm infants as a simple reciprocal trade‐off between mortality and the risk of vision‐threatening retinopathy, but this perspective oversimplifies the underlying physiology. Oxygen moves through a series of spatially distinct compartments without intrinsic regulation, with Fick's ...

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

Deep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Development and Field Test of Vibration Drag Reduction Tool

Shiyou jixie, 2021
The backing pressure phenomenon of bit is an important factor restricting the wellbore extension of horizontal wells. In order to effectively reduce the backing pressure phenomenon of bit, a vibration drag reduction tool was developed. The vibration drag

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

Journal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Aliphatic Poly(Carbonate)s with Acid Responsive Release Mechanisms for Micellar Anti‐Tumor Drug Delivery

Macromolecular Rapid Communications, EarlyView.
Micellar systems based on biodegradable aliphatic polycarbonates and acid‐responsive triggers enhance drug solubility, stability, and tumor‐selective release. This review covers micelles with acid‐cleavable drug linkages and those that disassemble via acid‐sensitive functionalities.

Disulfide‐Induced Inhibition of Epoxy Cationic Photopolymerization: A Route to Maskless Patterning

Macromolecular Rapid Communications, EarlyView.
This study investigates the role of disulfide‐containing molecules on the photopolymerization of epoxy monomers through cationic ring‐opening reaction, with the demonstration of the selective inhibition of the polymerization when disulfides are added to the photocurable formulation. This quenching is then exploited as a novel maskless photolithographic
