This type of statement makes it is clear we have passed no return point condemned to repeat history. The 1933 syndrome is already palpable.

Congratulation! I hope this peaceful and mutually approved agreement will set a stage for a new era of ethical capitalism improving not only the exchange of goods but also the outcome of our research and innovation between two continents.

The recent book by Paco Cerda β€œPresents” not only collects all this type of slogans by Jose Antonio, but also describes the devastating outcome when they are put in action.

I try to imagine this feeling of accomplishment of being the creator of literature included soon or later in the cannon of classics.

Why Nanoscience Needs Standardized Protocols─And How to Get There Nanoscience is a relatively young research field that has been built on the shoulders of consolidated areas ranging from solid-state physics to biology. Its interdisciplinary nature imposes the flow of heterogeneous data from various domains of predefined conventions that ultimately prevents workflow standardization, raising the possibility of further fragmentation and compromising the reproducibility. This is the time to establish good practices for experimental nanoscientists. This work proposes a set of simple rules that can facilitate data management and improve their reusability. Implementing the proposed protocol can have high initial cognitive costs but can also save energy and time in the long term. By adopting these practices, researchers can ensure the reusability of their data early in a project and accelerate the writing process.

In this perspective paper I propose a set of simple rules that can facilitate data management and improve their reusability.

Few days ago, I have made lists of all products and services I use on daily basis in work and personal life. From digital tools, electronic devices to clothing. The lists are quite unbalanced.

Closed-loop workflow for optimizing structural parameters of gold bipyramids with maximized plasmonic performance in photo-thermal heating, SERS, photoluminescence enhancement of an emitter, strong plexitonic coupling, and color transition upon clustering.

Closed-loop workflow for optimizing structural parameters of gold bipyramids with maximized plasmonic performance in photo-thermal heating, SERS, photoluminescence enhancement of an emitter, strong plexitonic coupling, and color transition upon clustering.

Systematic design methods can face further fragmentation of nanoplasmonics. We propose a pipeline combining Bayesian optimisation & simulations to accelerate the design of gold nanoparticles with superior plasmonic performance. A guide for experimentalists.

We are in a war on knowledge, a war on facts, and a war on truth. The atrocious sacking of the 11th Archivist of the United States, Colleen Shogan (which she announced on her LinkedIn account last night) heralds a new era of burning of the books. www.linkedin.com/posts/activi...

As Richard Ovenden put it in his book titled β€œBurning the books”, in less than 50 years, we will find ourselves in a situation of not knowing how we reached there.

Great reading, as usual. It seems to me that scientific publishing follows the Gresham Law, too.

Conclave: Golden Globes 2025 for best screenplay. Well deserved. While watching the movie a question resonated: will the supreme techno-magnate intervene with the next conclave to assure the moral approval for his actions?

A team of researchers has tested if a hierarchical design of nanoparticle-based systems can eventually generate strong thermal convection forces that eventually result in hydrodynamic oscillations.

1. Read, 2. write, 3. edit, 3. know your story, 4. develop own style.
I can only add: never edit while writing. These two are totally different cognitive processes.

Then, according to Bukowski, confidence measures the ignorance of own stupidity (and intelligence).
