GWANGJU, South Korea, Feb. 7, 2024 /PRNewswire/ -- A novel approach to address environmental challenges is the development and commercialization of robust hydrogen fuel cells. These cells contain a polymer electrolyte membrane that serves as a barrier between the electrodes (the conductors that enable the flow of electricity through a substance). This membrane conducts protons but inhibits the movement of electrons, hydrogen molecules, and oxygen molecules.

Key Points:

When a vehicle speeds up or slows down, the fuel cell operates inconsistently, leading to varying water production and causing the membrane to expand and contract.
The membranes produced had varying levels of PFPE, and among them, the one with 50% saturation exhibited reasonable electrochemical performance.
These results collectively suggest that incorporating the rubbery network modestly reduces electrochemical performance but significantly improves fatigue resistance and overall lifespan.
The introduction of a fuel cell system with stability, durability, and performance has the potential to pave the way for innovations in various industries.

GWANGJU, South Korea, Jan. 24, 2024 /PRNewswire/ -- Web 3.0 is an internet paradigm that is based around blockchain technology, an advanced database mechanism. Compared to Web 2.0, the current internet paradigm, Web 3.0 provides some added advantages, such as transparency and decentralized control structures. This is because Web 3.0 is designed to work over trustless and permissionless networks. Unfortunately, owing to certain technical difficulties, the implementation of Web 3.0 media streaming requires modifications to the service architecture of existing media streaming services. These difficulties include the degradation of user experience and Web 3.0's incompatibility with certain operating softwares and browsers.

Key Points:

Compared to Web 2.0, the current internet paradigm, Web 3.0 provides some added advantages, such as transparency and decentralized control structures.
Unfortunately, owing to certain technical difficulties, the implementation of Web 3.0 media streaming requires modifications to the service architecture of existing media streaming services.
To address these issues, a team of researchers, led by Assistant Professor Gi Seok Park from Incheon National University undertook a novel project.
In this study, the researchers proposed an end-to-end system architecture that is specifically designed for Web 3.0 streaming services.

GWANGJU, South Korea, Nov. 10, 2023 /PRNewswire/ -- The world has become increasingly industrialized over the past few centuries, bringing all sorts of technology and conveniences to the masses. However, workers in industrial environments are often at the risk of exposure to many dangerous gases, such as nitrogen dioxide (NO2). Inhaling this gas can lead to serious respiratory diseases like asthma and bronchitis, and severely compromise the health of industrial workers. Constant monitoring of NO2 levels is thus needed to ensure a safe workplace.

Key Points:

To help with this, many types of selective gas sensors have been developed using different organic and inorganic materials.
Some of them, such as gas chromatography sensors or electrochemical gas sensors, are highly sophisticated, yet expensive and bulky.
It was carried out in collaboration with researchers from Jeonbuk National University, including Professor Min Kim.
They incorporated a CsPbBr3 perovskite into a conductive polymer matrix to enhance its gas sensing performance while maintaining sensing speed.

Incheon National University Scientists Develop New Hydrogels for Wound Management

Retrieved on:

Monday, November 6, 2023

GWANGJU, South Korea, Nov. 6, 2023 /PRNewswire/ -- Wound management is essential to ensure a speedy and safe recovery, and tissue adhesive patches are an attractive option that can replace sutures and stapling. In a recent study, researchers from Korea developed a new type of gelatin-based tissue adhesive hydrogel that locally generates oxygen through a reaction mediated by calcium peroxide, which improves the adhesiveness of the material and greatly enhances the healing process.

Key Points:

Open wounds, whether caused by accidents or from medical procedures like surgery, require proper management to speed up healing and prevent infections.
While sutures and staples are common wound closure methods, they can cause secondary tissue injuries, potentially leaking fluids and gases and requiring anesthetics.
Against this backdrop, a team of researchers from Korea, led by Associate Professor Kyung Min Park of Incheon National University set out to find an effective solution to these limitations.
The research team has high hopes for the potential of the GOTs to become a cost-effective solution for wound management in a clinical setting.
