Continuous Stiffness Graded Metal–Ceramic Femoral Stems: UMAT‐Based Design and Finite Element Assessment

open access: yesAdvanced Engineering Materials, EarlyView.
Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

The Influence of Fiber Length and Fiber Length Distribution on Some Strength Characteristics of a Commercial Pulp [PDF]

open access: yes, 1952
In this thesis, four groups of fibers with varying average fiber lengths have been separated from a coniferous bleached kraft pulp which had been beaten to different levels of freeness.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

The structure, composition and preparation of injection-molded composite materials based on glass-filled polysulfone

open access: yesТонкие химические технологии, 2019
In the course of this study, compositions and designed structures for the polysulfone (PSF) and short glass fibers systems were calculated. Additionally, disperse-filled polymer composite materials (DFPCM) based on PSF-190 were classified in accordance ...

A Study of Methods Used to Determine Fiber Length and Fiber Length Distributions by Optical Means [PDF]

open access: yes, 1952
Various methods of slide preparation and fiber measurement are discussed in this literature survey. It is generally agreed that the time required to complete an individual test of fiber length has been an important factor in preventing a wider ...

The frequency distribution of fiber quality traits and dynamic change of fiber length during development. [PDF]

open access: yes, 2012
The mean values of fiber length (a), strength (b) and micronaire (c) obtained from four-year data of BC1S1 family lines. Average phenotypic values for parents (G. hirsutum acc. TM-1 and G. barbadense cv. Hai7124) are indicated by arrows.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Fracture behaviour of bamboo fiber reinforced epoxy composites [PDF]

open access: yes, 2017
In this work, experimental and numerical study on fracture behaviour of bamboo fiber reinforced epoxy composites is presented. Optimum NaOH concentration for treatment of bamboo fibers was determined through single fiber tensile test and microscopic ...

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.
