Revolutionizing Batteries: Coffee Grounds Power High-Performance Sodium-Ion Anodes

This study unveils a breakthrough in battery technology, utilizing coffee grounds to produce high-performance P-doped hard carbon anodes for sodium-ion batteries. The optimal doping level of phosphorus (2M H3PO4) enhances electrochemical performance, resulting in a remarkable reversible capacity of 341 mAh g-1 at 20 mA g-1 and an 83% initial Coulombic efficiency. The material’s porous structure, increased interlayer spacing, and C-P bonds contribute to its outstanding performance, marking a promising advancement in sustainable energy storage solutions.

Extracting the Best Flavor from Coffee

In Physics of Fluids, University of Huddersfield researchers explore the role of uneven coffee extraction using a simple mathematical model. They split the coffee into two regions to examine whether uneven flow does in fact make weaker espresso. One of the regions in the model system hosted more tightly packed coffee than the other, which caused an initial disparity in flow resistance. The extraction of coffee decreased the flow resistance further. Understanding the origin of uneven extraction and avoiding or preventing it could enable better brews and substantial financial savings by using coffee more efficiently.

Drinking coffee does not hinder the absorption of liquid thyroid medication

A new study conducted by Vertice Pharma confirms the absorption of an oral levothyroxine sodium solution (Thyquidity® 100g/ 5mL) was not affected by consuming coffee 5 minutes after the dose, according to research being presented Saturday at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Ga.

To sustain a thriving café culture, we must ditch the disposable cup.

Takeaway coffees – they’re a convenient start for millions of people each day, but while the caffeine perks us up, the disposable cups drag us down, with nearly 300 billion ending up in landfill each year.

While most coffee drinkers are happy to make a switch to sustainable practices, new research from the University of South Australia shows that an absence of infrastructure and a general ‘throwaway’ culture is severely delaying sustainable change.

Daily coffee consumption associated with improved survival in patients with metastatic colorectal cancer

In a large group of patients with metastatic colorectal cancer, consumption of a few cups of coffee a day was associated with longer survival and a lower risk of the cancer worsening, researchers at Dana-Farber Cancer Institute and other organizations report in a new study.

The Complex Biology Behind Your Love (or Hatred) of Coffee

Why do some people feel like they need three cups of coffee just to get through the day when others are happy with only one? Why do some people abstain entirely? New research suggests that our intake of coffee – the most popular beverage in America, above bottled water, sodas, tea, and beer – is affected by a positive feedback loop between genetics and the environment.
