Minimal virtual reality‐induced symptoms and effects in anatomy education across controller types

Anatomical Sciences Education, EarlyView.
Abstract With the increasing adoption of virtual reality (VR) in anatomy education, understanding VR‐induced symptoms and effects (VRISE) is pivotal to effective curriculum design. To compare self‐reported VRISE across different VR controller types, the study included 199 responses from students aged 18–54, enrolled in visceral anatomy or neuroanatomy ...

Accuracy of Freehand Versus Navigated External Ventricular Drainage and Comparison of Insertion Trajectories: A Systematic Review and Meta Analysis

Clinical Anatomy, EarlyView.
ABSTRACT The external ventricular drainage is a routine neurosurgical procedure, most often performed by cannulating the frontal horn of the lateral ventricle. Various entry points and insertion trajectory definitions have been proposed; nevertheless, it remains unclear which approach yields the highest success rate.

Magnetic Supraparticles as Identifiers in Single‐Layer Lithium‐Ion Battery Pouch Cells

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
As an alternative to externally applied optical identifiers, magnetic supraparticles (SPs) can be used for contactless identification of lithium‐ion battery pouch cells via magnetic particle spectroscopy. This study validated the integration and detection of magnetic markers in three model scenarios.

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...

Bio‐Inspired Sclerotization of Lignin: A Robust Adhesive for Photothermal Wood‐Based Panels

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance lignin adhesive is engineered via an insect‐inspired sclerotization strategy involving oxidation and hyperbranched polymer grafting, overcoming lignin's adhesion failure, and yielding a wet shear strength of 1.02–1.21 MPa. The adhesive endows wood‐based panels with photothermal functionality; building energy simulations indicate HVAC‐

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.
