Wireless blood pressure sensor implantation in sheep: A detailed technique

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

Enhanced Rheological and Filtration Performance of Drilling Fluids Using Fe3O4/Saponin/Cu(II) Nanocomposites: Synthesis, Characterization, and Application

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Drilling fluids used in high‐performance well operations often struggle to maintain rheological stability, colloidal dispersion, and filtration control under harsh downhole conditions. This study engineered a multifunctional Fe3O4@Saponin/Cu(II) nanocomposite to address these challenges.

High Density Polyethylene/Ground Tire Rubber Composites Compatibilized by Dicumyl Peroxide

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT In this study, the thermal behavior of dicumyl peroxide (DCP) was first evaluated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which confirmed a peak decomposition temperature around 172°C, highlighting its incompatibility with standard melt‐mixing techniques for most polyolefins. To overcome this limitation,

Real‐time monitoring of root dielectric properties for assessing crop plant damage caused by foliar application of glyphosate

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

Thermal Conductivity and Tunable Thermal Anisotropy of Magnetic CrSBr Monolayer

open access: yesAdvanced Physics Research, EarlyView.
Top (left) and side view of single‐layer CrSBr (right). Phonon transport is strongly anisotropic, with a lattice thermal conductivity along the a‐lattice vector which is almost twice the one along the b‐vector (κxx$\kappa _{xx}$ = 1.8 κyy$\kappa _{yy}$). ABSTRACT We present first‐principles calculations of the thermal conductivity, κ${\bm \kappa }$, of

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...
