Synthesis, Updated Characterization, and Reactivity of Low‐Valent Titanocene Complexes

European Journal of Inorganic Chemistry, EarlyView.
Syntheses and characterizations are provided for a series of low‐valent titanocene complexes including halotitanocene(III) dimers, [Cp2Ti(κ2‐DME)][BAr4] cations, and heterobimetallic [Cp2Ti(μ‐Cl)2AlR2]. Additionally, a monomeric titanacyclopropene complex featuring a pendent phosphine was prepared, and C─F bond activation upon reduction of [Cp{η5:κ2F2 ...

A Zonal‐Meridional Projection Method for Quantifying Global Land‐Ocean Moisture Transport

International Journal of Climatology, EarlyView.
We present a physically consistent and computationally efficient method to quantify global coastal moisture transport by projecting vertically integrated moisture flux onto signed land–ocean boundary segments. The signed projection naturally distinguishes ocean‐to‐land inflow and land‐to‐ocean outflow without explicit directional classification ...

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Convection in fluid and porous media [PDF]

, 2003
The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

Advanced Materials, Volume 38, Issue 56, 8 October 2026.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 570-591, October/December 2026.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, Volume 22, Issue 55, 1 October 2026.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

Convection naturelle dans les enceintes: nanofluide

Revue des Énergies Renouvelables, 2012
Dans ce travail, on a mené une étude numérique de la convection naturelle laminaire stationnaire dans une enceinte carrée chauffée par une section carrée et remplie d’un mélange d’eau et des nanoparticules. Les équations gouvernantes ont été discrétisées
