The First Graphene-Enhanced Concrete Hits the Market Image Credit: Concrene The addition of just a touch of graphene could make the worlds most ubiquitous building material stronger, more durable and even a touch greener. The first graphene-enhanced concrete is about to hit the American market. April 2021 will see the culmination of a project between the Advanced Materials Division of Thomas Swan¹ and Concrene² — a UK-based nanotech company.  The addition of a tiny amount of graphene  �...

Biopolymer-Coated Nanocatalyst Could Drive a Hydrogen Fuel-Based Future Image Credit: Shutterstock.com / peterschreiber.media A newly devised nanorod catalyst could help water splitting by sunlight become a viable and eco-friendly route to hydrogen fuel. Humanity’s consumption of fossil fuels drives massive detrimental changes to the environment, releasing carbon dioxide and other greenhouse gases into the atmosphere that are fueling the climate change crisis. Thus, a long-term sustainable a...

Freshwater Fish are Facing a Catastrophic Decline Image Credit: Shutterstock.com/ francesco de marco Biodiversity in freshwater ecosystems is under severe threat, with up to one-third of freshwater fish species facing extinction, suggests a WWF report.  A new report from the World Wide Fund (WWF)¹ is a wake-up call to governments worldwide, highlighting that human activities are severely impacting freshwater fish.  The WWF has collaborated with 16 other conservation agencies, including the ...

3D-Printed Electrochemical Ring for the Monitoring of Glucose Levels Image Credit: Shutterstock.com / nobeastsofierce Blood glucose monitoring can be a daily chore for people living with diabetes, but relief could be on the horizon thanks to a wearable glucometer that detects sugar in a user’s sweat.  It is currently estimated that over 415 million people worldwide are living with either Type 1 or Type 2 diabetes. That means that for 1 in 11 of the world’s adult population, regular glucos...

3D Printing a New Type of Airway Stent Image Credit: Komsan Loonprom / Shutterstock.com A new type of 3D printed airway stent could make treating upper airway obstructions quicker and safer. Obstruction of central airways and the impairment of airflow that results from it is a major cause of death in surgery, especially for patients suffering from lung cancer, and because of a major rise in this disease, cases of central airway obstruction (CAO) are also on the rise. This narrowing  —  ...

What Effect is Rising Noise Pollution having on Marine Life? Image Credit: Rich Carey / Shutterstock.com When it comes to considering the impact of human-caused pollution on marine life, there could be one major factor that we have been overlooking; the effects of noise pollution. The soundscapes of the worlds oceans today are massively different from how they were prior to the industrial revolution. As human activity grows in the period of modern history that we have dubbed Anthropocene Epoch,...

The Graphene-Based Biosensors that can Detect Blood Disorders Image Credit: Phonlamai Photo / Shutterstock.com A new biosensor uses laser printed graphene to detect biomarkers at low concentrations and without prior labeling, thus providing a quick, cheap and efficient test for blood disorders. A new laser printed graphene (LIG) based electrode biosensor developed by researchers at the University of Regensburg, Germany, and Chung-Ang University, Korea, could detect biomarkers that indicate bloo...
