Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration

open access: yesAdvanced Functional Materials, EarlyView.
High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...

SEED-GUIDED, FAULT-AWARE HORIZON TRACKING VIA GREEDY PROPAGATION FOR GEOLOGICAL MODELLING

open access: yesRudarsko-geološko-naftni Zbornik
The Gola Gas field in the northwestern Drava Basin lies within the structurally complex petroleum system. Its sandstone reservoirs exhibit spatial heterogeneity due to deltaic fan sedimentation, necessitating robust interpretation tools.

A Clustering-Based Bubble Method for Generating High-Quality Tetrahedral Meshes of Geological Models

open access: yesApplied Sciences, 2020
High-quality mesh generation is critical in the finite element analysis of displacements and stabilities of geological bodies. In this paper, we propose a clustering-based bubble method for generating high-quality tetrahedral meshes of geological models.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

open access: yesAdvanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

COMBINING THE 3D GEOLOGICAL AND GEOSTATISTICAL MODELLING OF GYPSUM CONCENTRATION, USING HISTORICAL BOREHOLE AND BLASTHOLE INFORMATION

open access: yesRudarsko-geološko-naftni Zbornik
Geostatistics is used for estimating grade content in an ore deposit, thus enhancing the 3 Dimensional (3D) geological model precision, lowering the geological risk and boosting the performances of the mining industry. Despite the advantages, for decades

Spiro‐Phenothiazine Hole‐Transporting Materials: Unlocking Stability and Scalability in Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

open access: yesAdvanced Materials Interfaces, EarlyView.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

Self‐Assembled Calcite Architectures for Programmable Information Storage

open access: yesAdvanced Materials Technologies, EarlyView.
Programmable biomineralization enables the formation of 3D calcite architectures that encode information through spatially defined refractive‐index modulations. Data are written via laser‐directed mineralization, stored in stable voxelized mineral structures, and retrieved non‐destructively through optical diffraction, offering a pathway toward ultra ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
