Review on the prediction of residual stress in welded steel components [PDF]

, 2020
Residual stress after welding has negative effects on the service life of welded steel components or structures. This work reviews three most commonly used methods for predicting residual stress, namely, empirical, semi-empirical and process simulation ...

Emergence of non-Fourier hierarchies [PDF]

, 2018
The non-Fourier heat conduction phenomenon on room temperature is analyzed from various aspects. The first one shows its experimental side, in what form it occurs and how we treated it. It is demonstrated that the Guyer-Krumhansl equation can be the next

Effect of aramid and carbon fibers with nano carbon particles on the mechanical properties of EPDM rubber thermal insulators for solid rocket motors application

Polymer Testing, 2021
The effect of varying compositions (5, 10, 15, 30 Phr) of aramid fiber in the pulp form Kevlar (KP), carbon mono fiber (CMF), and nano-carbon black (NCB) as filler for Trilene liquid polymers - Ethylene propylene diene monomer (EPDM) on mechanical properties were examined. All formulations contained 100 Phr EPDM, 60 Phr Ammonium polyphosphate (AP), and

A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond [PDF]

, 2016
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitride, etc.) have been discovered.

Statistical mechanics of thin spherical shells

, 2016
We explore how thermal fluctuations affect the mechanics of thin amorphous spherical shells. In flat membranes with a shear modulus, thermal fluctuations increase the bending rigidity and reduce the in-plane elastic moduli in a scale-dependent fashion ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
