Permeable inspection of pharmaceuticals: Real-time tablet quality inspection system developed

Led by Assistant Professor Kou Li, a research group at Chuo University, Japan, has developed a synergetic strategy among non-destructive terahertz (THz)–infrared (IR) photo-monitoring techniques and ultrabroadband sensitive imager sheets toward demonstrating in-line real-time multi-scale quality inspections of pharmaceutical agent pills.

The paper has been published in Light: Science & Applications.

While non-destructive in-line monitoring at manufacturing sites is essential for safe distribution cycles of pharmaceuticals, efforts are still insufficient to develop analytical systems for detailed dynamic visualization of foreign substances and material composition in target pills.

High-entropy alloys: How chaos takes over in layered carbides as metal diversity increases

In the tug-of-war between order and chaos within multielemental carbides, entropy eventually claims victory over enthalpy by pushing the system toward complete disorder as the diversity of elements in the material increases, as revealed in a study published in Science.

Researchers synthesized 40 layered carbide phases with composition MAlX materials (M is a transition metal, Al is for aluminum, and X is either C or N), where the number of M was between 2 and 9.

Their goal was to uncover the trends in short-range ordering and compositional disorder in so-called high– systems. They found that in carbides with fewer constituent elements, short-range order driven by enthalpy dominated. However, as the number of elements increased, entropy took control, randomizing the metal configurations.

Achieving low resistance and high performance in magnetic tunnel junctions using high-entropy oxides

A NIMS research team has developed a magnetic tunnel junction (MTJ) featuring a tunnel barrier made of a high-entropy oxide composed of multiple metallic elements. This MTJ simultaneously demonstrated stronger perpendicular magnetization, a higher tunnel magnetoresistance (TMR) ratio (i.e., the relative change in electrical resistance when the magnetization directions of the two ferromagnetic layers switch between parallel and antiparallel alignments) and lower electrical resistance.

These properties may contribute to the development of smaller, higher-capacity and higher-performance (HDDs) and magnetoresistive random access memory (MRAM).

Rethinking Physics: Scientists Discover a “Giant” New Twist on a 140-Year-Old Effect

Their results pave the way for developing advanced electronic devices that rely on nonmagnetic materials. For the first time, researchers in Japan have detected a giant anomalous Hall effect (AHE) in a material that is not magnetic. The breakthrough was made using high-quality thin films of Cd3As

Butterfly wings inspire solution to impossible optics problem

The iridescent blue of butterfly wings has inspired researchers to find a solution to a challenge previously considered insurmountable—dynamically tuning advanced optical processes at visible wavelengths.

The result is a patterned layer of material a fraction of the thickness of a hair, that could underpin radical new optical technology: applications of the technology are diverse, ranging from adaptive camouflage, through biosensing to quantum light engines for on-chip computing and secure communications.

The research is published in Science Advances. The first author is Dr. Mudassar Nauman, from the ARC Center of Excellence for Transformative Meta-Optical Systems (TMOS) and BluGlass Ltd.

Squishy ‘smart cartilage’ could target arthritis pain as soon as flareups begin

Researchers have developed a material that can sense tiny changes within the body, such as during an arthritis flareup, and release drugs exactly where and when they are needed.

The squishy material can be loaded with that are released in response to small changes in pH in the body. During an flareup, a joint becomes inflamed and slightly more acidic than the surrounding tissue.

The material, developed by researchers at the University of Cambridge, has been designed to respond to this natural change in pH. As acidity increases, the material becomes softer and more jelly-like, triggering the release of drug molecules that can be encapsulated within its structure. Since the material is designed to respond only within a narrow pH range, the team says that drugs could be released precisely where and when they are needed, potentially reducing side effects.

Decades-Old Quantum Puzzle Solved: Graphene Electrons Violate Fundamental Law of Physics

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies.

For decades, quantum physicists have wrestled with a fundamental question: can electrons flow like a flawless, resistance-free liquid governed by a universal quantum constant? Detecting this unusual state has proven nearly impossible in most materials, since atomic defects, impurities, and structural imperfections disrupt the effect.

World First: Physicists Created a Time Crystal That We Can Actually See

Physicists have just made a new breakthrough in the enigmatic realm of time crystals.

For the first time, a time crystal has been built that can be directly seen by human eyes, rippling in an array of neon-hued stripes. The material’s construction could open up a whole new world of technological possibilities, including new anti-counterfeiting measures, random number generators, two-dimensional barcodes, and optical devices.

“They can be observed directly under a microscope and even, under special conditions, by the naked eye,” says physicist Hanqing Zhao of the University of Colorado Boulder.

Roll-to-roll method streamlines DNA sequencing with faster, more efficient fluidics

Researchers at Beijing Genomics and IMDEA Nanociencia institutes have introduced a novel method that could significantly accelerate efficiency and reduce the cost of handling fluidics in DNA sequencing.

Traditional DNA sequencing relies on flow cells, where liquid reagents are repeatedly pumped in and out for each of the sequencing reactions. For large-scale sequencing, this process involves immersing into reagents—a method that works well at industrial scale but is impractical for smaller labs or , where sample sizes are limited and drying effects become a problem.

The new approach turns that process on its head. Instead of pumping fluids through a chamber, the researchers use a roll-to-roll technique that gently shears the liquid across the surface. This dramatically improves efficiency, allowing reagents to be replaced more quickly and uses up to 85 times less material. As a result, DNA sequencing that once took days can now be completed in under 12 hours, with significantly lower costs.
