Dental Microwear Texture Analysis on Radular Teeth

Advanced Materials Interfaces, EarlyView.
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

Adsorbent Materials for Hydrocarbons Removal by Geopolymerization of Halloysite Clay Nanotubes Filled Within Chitosan Matrix

Advanced Materials Interfaces, EarlyView.
Alkaline activation of halloysite clay nanotubes embedded in a chitosan matrix converts bionanocomposite films into porous geopolymeric materials with enhanced adsorption capacity toward hydrocarbons in both vapor and aqueous phases. The improved adsorption performance was demonstrated by the efficient capture of dodecane vapors and phenol from water ...

Experimental Investigations of the Properties of Foam Concrete for Utilisation as Crushed Lightweight Aggregates in Building Slabs

Applied Sciences
Foam concrete is examined for use as a lightweight aggregate in concrete for building slabs. Crushed foam concrete should substitute LECAs in areas where LECAs are inaccessible. Suitable foam concrete mixes with and without admixtures and fine aggregates

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

A prospective, open-label, randomized, crossover study to compare the pharmacokinetics of crushed methotrexate with that of the tablet formulation in patients with head-and-neck cancer

Cancer Research, Statistics, and Treatment
Background: Crushing solid dosage forms is often required in patients with swallowing difficulties; however, the pharmacokinetic (PK) impact of this alteration is not well-studied.

Pre‐Regenerative Endothelial Cells Empowered by Antler Blood Exosomes Orchestrate Peripheral Nerve Repair

Advanced Science, EarlyView.
The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.

Crushing machines [PDF]

, 1895
Crushing machines may be divided into: crushers, rolls, and pulverizers. Ore as it comes from the mine is usually in larger lumps which require breaking up preparatory to the subsequent treatment it may receive.

Consideration of reinforced concrete crushing through cohesive models

Revista IBRACON de Estruturas e Materiais, 2014
In this work, the overlapping crack mode is considered. It permits the modeling of concrete crushing through cohesive surfaces, in a similar way used to simulate fracture.

Prediction of Cone Crusher Performance Considering Liner Wear

Applied Sciences, 2016
Cone crushers are used in the aggregates and mining industries to crush rock material. The pressure on cone crusher liners is the key factor that influences the hydraulic pressure, power draw and liner wear.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.
