Electromagnetic Characteristics of Thin Polyethylene-Carbon-Polyethylene Films

Russian Physics Journal, 2015
A method of manufacturing a polyethylene – expanded carbon – polyethylene layered structures which allows thin (down to 90 μm) and flexible sandwiches to be easily made, is suggested. The electromagnetic properties of the manufactured composite materials at frequencies from 1 MHz to 3 GHz, 26–37.5 GHz, and 0.1–1.4 THz are analyzed.

Electrical pulse stimulation reflecting the episodic nature of real‐life exercise modulates metabolic and secretory profile of primary human myotubes

FEBS Open Bio, EarlyView.
Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.

Aqueous synthesis of Nb-modified SnO2 quantum dots for efficient photocatalytic degradation of polyethylene for in situ agricultural waste treatment

Green Processing and Synthesis, 2021
Low density polyethylene is widely used in agricultural production. It is of low cost and able to significantly improve the quality of fruits. However, its decomposition under natural circumstances needs more than one hundred of years.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Blends of linear-low-density polyethylene and thermoplastic bloodmeal using maleic anhydride grafted polyethylene as compatibilizer [PDF]

, 2012
Linear Low-Density Polyethylene (LLDPE) was blended with Novatein Thermoplastic from bloodmeal (NTP.) The compatibilizing effect of maleic anhydride grafted polyethylene (PE-g-MAH) on mechanical, morphology thermal properties and water absorption were ...

Growth Differentiation Factor 15 Elevation in the Central Nervous System Is Associated With Failure to Thrive in Alexander Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Alexander disease (AxD) is a severe neurodegenerative disorder caused by gain‐of‐function mutations in the gene for GFAP, which lead to protein aggregation and a primary astrocytopathy. Symptoms vary, but failure to thrive (FTT) and frequent emesis are common and cause significant morbidity. Here we investigate GDF15, a member of the

Post-radiation oxidation reaction of three types of polyethylene films

Fushe yanjiu yu fushe gongyi xuebao
The long-term, slow reaction that occurs when polyethylene (PE) is exposed to oxygen after ionizing radiation is known as post-radiation oxidation, which significantly affects the long-term performance of radiation-modified PE materials.

Evaluation of photodegradation in LDPE/modified starch blends

Polímeros, 2009
Photodegradation of LDPE/modified starch blends 80/20 m/m has been examined by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X ray diffraction (DRX) before and after exposure to ultraviolet radiation (UV). Samples

The effect of foot orthoses on midfoot pain and the volume of bone marrow lesions in the midfoot: a randomized mechanism of action study

Arthritis Care &Research, Accepted Article.
Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain and MRI‐confirmed midfoot BMLs.
