Preparation and Characterization of PMMA-HDPE and HDPE-PMMA Binary Polymer Blends [PDF]

Engineering and Technology Journal, 2017
A comparison was made on the mechanical characteristics of binary blends polymethylmethacrylate/ high density polyethylene (PMMA-%HDPE) and vice versa. Analysis of morphology by SEM has been also accomplished.

Analysis of the Ball Clutch Mechanism of D-Type Shore Hardness Tester

Transactions of the Japan Society of Mechanical Engineers, 1962
It is observed by means of a differential transformer how the hammer of D-type Shore hardness tester is caught in the ball clutch at its height of rebound. The observations made under various conditions show that the hammer vibrates up and down at a frequency of 140∼280c/s before it stops at a little lower height than the height of rebound.

Field‐Programmed Anisotropy in Magneto‐Piezoelectric Composites for Material‐Encoded Mechanoperception

Advanced Materials, EarlyView.
Field‐programmed anisotropy imparts material‐level intelligence to soft composites. Magnetic torque dynamics drive magneto‐piezoelectric nanowires from random dispersion into deterministic axial alignment. The resulting hierarchical percolation networks confine electromechanical coupling to specific axes and intrinsically decouple superposed force ...

FRICTION AND WEAR OF EPOXY REINFORCED BY IRON NANO PARTICLES [PDF]

Journal of the Egyptian Society of Tribology, 2018
Epoxy-Iron composite specimens were prepared by adding different weight fractions of iron nano particles (0, 10, 15, and 20 wt. %) to the epoxy matrix. Friction and wear testing as well as hardness testing were conducted on the specimens.

Study of the Effect of the Variation Effect of Water Temperatures on Shore (D) Hardness for Some Polymers

Journal of Al-Nahrain University Science, 2013
The current investigation was carried to study and determine the value of shore [D] hardness for different kinds of polymers [Epoxy [Ep], unsaturated polyester [UPE] and unplasticised PVC. After the preparation our samples Shore [D] hardness values were measured for the samples at 25 oC.

Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures

Advanced Materials, EarlyView.
Coherent isostructural high‐entropy oxide heterostructures are realized despite remarkable >5% interfacial lattice distortion. The resulting buried interface exhibits abrupt valence reconstruction which contributes to 2 × enhanced exchange bias in the heterostructure relative to constituent layers, demonstrating how chemical disorder enabled anomalous ...

Additive‐Manufactured, Multifunctional Bioreactor Technology for Dynamic Culture of 3D Bioprinted Tissue Models

Advanced Materials Technologies, EarlyView.
We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Optimization of the mechanical properties of polyester/coconut shell ash (CSA) composite for light-weight engineering applications

Scientific Reports, 2023
The mechanical properties of coconut shell ash (CSA) reinforced polyester composite have been optimized. Various test specimens were developed by dispersing 10, 20, 30 and 40 wt.%, of CSA in unsaturated polyester resin in decreasing particle sizes of 40,

An Imaging‐Guided, Patient‐Specific Guiding Aid (RWNGuide) for Safe and Reproducible Inner Ear Drug Delivery

Advanced Materials Technologies, EarlyView.
A patient‐specific, imaging‐guided aid enables precise and reproducible drug delivery to the inner ear. By guiding therapeutic agents directly to the round window niche, this approach reduces variability in drug localization, improves delivery safety, and addresses a critical bottleneck in inner ear therapy, offering a scalable strategy for precision ...
