The transfer of chemical vapour deposited graphene from its parent growth catalyst has become a bottleneck for many of its emerging applications. The sacrificial polymer layers that are typically deposited onto graphene for mechanical support during transfer are challenging to remove completely and hence leave graphene and subsequent device interfaces contaminated. Here, we report on the use of...

Lightweight foam sandwich structures have excellent energy absorption capacity, combined with good mechanical properties and low density. The main goal of this study is to test the application an innovative hybrid protective device in offshore wind turbine (OWT). results are useful for structure applications. Different lightweight materials (aluminum foam, agglomerated cork, polyurethane foam) ...

researchers suggested that the individual fit test be conducted to estimate the protection effectiveness of workers’ hearing protection device (hpd) while working. practically, it is convenient to conduct single, instead of multiple, fit test measurement. this study examined if a single trial of earplug fit test can represent multiple performances. additionally, it investigated how much noise e...

Noise-induced hearing loss (NIHL) is irreversible damage to the ear caused by traumatic noise exposure. This is mainly due to mechanical damage to outer hair cells (OHCs), a type of sensory cell in the inner ear. Recently, prior conditioning with sublethal stressors has been reported to protect the inner ear from acoustic injury, realizing less hearing loss. To explore the stress-actuated prote...

Monitoring of phytopathological situation in crops is the basis for biological justification need protective measures, allowing to obtain a yield close potentially possible. The results monitoring spring wheat varieties are presented paper. Studies were carried out 2019–2021 laboratory phytopathology and experimental field Institute Plant Protection. Standard methods used during work. main crit...

Caffeic acid phenethyl ester (CAPE) is an important active component of propolis, which is derived from honeybee hives. It has received increasing attention in a variety of medical and pharmaceutical research, due to its anti‑oxidant, antiproliferative, anti‑inflammatory, antiviral and antifungal activity, in addition to its antineoplastic properties. Besides the use of CAPE as an antioxidant a...

This paper will outline the features required for a multifunction protective relay or intelligent electrical device (IED) that meets the special requirements of the distributed generation environment.
