Laser-patterned thin films that swell into kirigami-like structures offer new opportunities in hydrogel technology

New options for making finely structured soft, flexible and expandable materials called hydrogels have been developed by researchers at Tokyo University of Agriculture and Technology (TUAT). Their work extends the emerging field of "kirigami hydrogels," in which patterns are cut into a thin film allowing it to later swell into complex hydrogel structures. The research is published in the journal Science and Technology of Advanced Materials. Hydrogels have a network of water-attracting (hydrophilic) molecules, allowing their structure to swell substantially when exposed to water that becomes incorporated within the molecular network. Researchers Daisuke Nakagawa and Itsuo Hanasaki worked with an initially dry film composed of nanofibers of cellulose, the natural material that forms much of the structure of plant cell walls.

Here I document investigation of rubbery clots in a COVID19 unvaccinated patient mid 60’s with history of acute myocardial infarction in 2020, who developed multiple embolic strokes from blood clots after heart catheterisation. He was treated with Aspirin, Plavix and Eliquis - all three are blood thinners. In 2022 the patient developed congestive heart failure and Atrial fibrillation, hence remained on Eliquis. In August 2024, after receiving dental anesthetics during another hospitalization a clot in his left ventricle was found while on Eliquis. The patient came to me for second opinion on self assembly nanotechnology possibly causing ongoing blood clotting.

I had previously reported rubbery blood clot formation from shedding in a patient on multiple blood thinners:

Rubbery Clot Development In C19 Unvaccinated Individual With Previous Deep Vein Thrombosis and Massive Pulmonary Emboli - While On Eliquis, Nattokinase, Lumbrokinase and Serreptase

I also showed that COVID19 unvaccinated blood creates rubbery clots that can be inhibited by EDTA/ Vitamin C and Methylene Blue:

C19 Unvaccinated Have Same Blood Clotting Problem As C19 Vaccinated - EDTA And Vitamin C Prevents Blood Clotting In C19 Unvaccinated

Methylene Blue Prevents Rubbery Clot Formation, Essential Oils Help Too - Experiment Documentation

I have been reporting on unvaccinated rubbery clots since 2022:

Latest Technology Trends

3 New Inventions That Will Change The World

1. Commercial nuclear fusion power

Nuclear fusion, in its most common form, is the process of energy being released when bits (“atomic nuclei”, if you’re fancy) of hydrogen are exposed to extreme heat and combined. This process releases massive amounts of energy, which humanity is increasingly hungry for. That’s how the sun works too, by the way.

Several countries have heavily invested in fusion research, and private companies are also conducting their own trials. The ITER reactor, which is under construction in France and due to begin operation in 2026, is the first reactor that should produce energy-positive fusion; but dozens of others are being built.

2. 4D printing

The name 4D printing can lead to confusion: I am not implying that humanity will be able to create and access another dimension. Put simply, a 4D-printed product is a 3D-printed object which can change properties when a specific stimulus is applied (submerged underwater, heated, shaken, not stirred…). The 4th Dimension is therefore Smart Materials.

The key challenge of this technology is obviously finding the relevant “smart material” for all types of uses (namely a hydrogel or a shape memory polymer for the time being). Some work is being done in this space, but we’re not close to being customer-ready, having yet to master reversible changes of certain materials.

The applications are still being discussed, but some very promising industries include healthcare (pills that activate only if the body reaches a certain temperature), fashion (clothes that become tighter in cold temperatures or shoes that improve grip under wet conditions), and homemaking (furniture that becomes rigid under a certain stimulus). Another cool use case is computational folding, wherein objects larger than printers can be printed as only one part.

3. Generative design AI

Generative AI technology uses deep learning to generate creative assets such as videos, images, text and music. This technology is no longer new since it entered the mainstream in late 2022. While you may have played with (and enjoyed!) the likes of ChatGPT and Midjourney, they’re barely more than surface-level distractions.

Tom Cruise riding a t-rex in Hogwarts

Corporate use for generative AI is far more sophisticated. If used to its full extent, it will reduce product-development life cycle time, design drugs in months instead of years, compose entirely new materials, generate synthetic data, optimize parts design, automate creativity… In fact, experts predict that by 2025, 30% of outbound marketing messages from large organizations will be synthetically generated, and by 2030, a major blockbuster film will be released with 90% of the film generated by AI.

Going beyond the most headline-grabbing use cases, studies have shown that Gen. AI increases productivity for a variety of tasks, with specific benefits for low-ability workers and less experienced employees. Put simply, these tools will level the playing field.

This is happening today, and will continue to happen, with increasing success, over the coming decade. That is, if we can navigate the many risks associated with generative AI. I’m particularly worried about deep fakes, copyright issues, and malicious uses for fake news.
