Applicability of mechanical tests for biomass pellet characterisation for bioenergy applications [PDF]

open access: yes, 2018
In this paper, the applicability of mechanical tests for biomass pellet characterisation was investigated. Pellet durability, quasi-static (low strain rate), and dynamic (high strain rate) mechanical tests were applied to mixed wood, eucalyptus ...

Superior Impact‐Resistant Composite Hydrogels Through an Ionic Coupling Strategy

open access: yesAdvanced Materials, Volume 38, Issue 26, 8 May 2026.
An ionic coupling strategy is developed to simultaneously reinforce networks and interfaces in composite hydrogels. Sodium citrate acts as a single multifunctional ionic coupler to strengthen the poly(vinyl alcohol) matrix via the Hofmeister effect, reinforce the chitosan–sodium alginate nanofiber network via desolvation and electrostatic crosslinking,

Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Signal Correction for the Split-Hopkinson Bar Testing of Soft Materials

open access: yesDynamics
The Split-Hopkinson pressure bar (SHPB) test is a commonly accepted experiment to investigate the material behavior under high strain rates. Due to the low impedance of soft materials, here, the test has to be performed with plastic bars instead of metal

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study

open access: yesEngineering Reports, Volume 8, Issue 4, April 2026.
The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 96-105, March 2026.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring
