Experimental Study of Gas Microbubbles on Oil‐Infused Wrinkled Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Microbubbles are observed on both superhydrophobic (SHS) and lubricant‐infused surfaces (LIS) immersed to gassed water. The bubbles on LIS are stabilized by the lubricant cloaking layer, while bubbles on SHS shrink vertically over the same time frame.

INVESTIGATING AN INNOVATIVE MODEL FOR DIMENSIONAL SEDIMENTARY ROCKS CHARACTERIZATION USING ACOUSTIC FREQUENCIES ANALYSIS DURING DRILLING

open access: yesRudarsko-geološko-naftni Zbornik, 2018
Determining geomechanical characteristics of rocks plays a significant role in all consequent designing stages of geosciences. On the other hand, drilling is one of the considerable operations in primer phases of extracting rocks.

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...

Wave Propagation in Porous Elastoplastic Rocks: Implication for Seismic Attenuation [PDF]

open access: yesarXiv, 2018
We develop and study a 1D model for the acoustic wave propagation with two-phase physics and irreversible elastoplastic deformations in the rock matrix. We address the effect of the P-wave energy attenuation due to pore-scale plastic yielding in pre-stressed sedimentary rocks.

Research core drilling in the Manson impact structure, Iowa [PDF]

open access: yes
The Manson impact structure (MIS) has a diameter of 35 km and is the largest confirmed impact structure in the United States. The MIS has yielded a Ar-40/Ar-39 age of 65.7 Ma on microcline from its central peak, an age that is indistinguishable from the ...

Ammonia Dynamics in the Human Body: Insights in Biomedical Sensing Technologies

open access: yesAdvanced Sensor Research, EarlyView.
Ammonia (NH3) is a significant biomarker in diagnostics, affecting the respiratory system, stomach, liver, kidneys, bladder, and gastrointestinal tract. NH3 detection, using sensors, has the potential to improve medical diagnosis. This review examines recent advancements in NH3 sensing technologies and explores future research directions, including ...

Nanocrystalline Cellulose from the Solitary Tunicate Phallusia Mammillata, a Valuable Nanocellulose Precursor

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores the potential of locally harvested Phallusia mammillata, a tunicate usually discarded as waste from mussles farming as a viable source for producing various high‐grade cellulose derivatives in the form of nanofibrils (NFC) and nanocrystals (CNC). Abstract Ascidians are ubiquitous filter‐feeding marine invertebrates, the only animals
