Interestingly, even Edwin Hall, the greatest scientists of all, who discovered the Hall effect, attempted to measure his effect using a beam of light with no success. He summarizes in the closing sentence of his notable paper from 1881: “I think that, if the action of silver had been one tenth as strong as that of iron, the effect would have been detected. No such effect was observed.” (E. Hall, 1881). By tuning in to the right frequency—and knowing where to look—researchers

A team of material scientists led by Qiang Wang and Shuang Yuan from Northeastern University in Shenyang, China recently have provided a novel strategy for modulating crystalline-amorphous composites and electronic structures to enhance the hydrogen evolution reaction.

In the new study, the researchers demonstrated that anodic polarization of graphite in an electrochemical cell induces the formation of likely oxidized graphene sheets that spontaneously self-assemble into fullerenes and hollow spheres. The final product was characterized using scanning electron microscopy (SEM), atomic force microscopy (AFM), high-resolution transmission electron microscopy (HRTEM), mass spectrometry (MALDI-TOF), and visible ultraviolet spectroscopy (UV-Vis)

Led by Assistant Professor Kou Li, a research group in Chuo University, Japan, has developed chemically enriched photo-thermoelectric (PTE) imagers using semiconducting carbon nanotube (CNT) films, resulting in the achievement of enhanced response intensity and noise reduction, that enables efficient remote and on-site inspections.

Stacking and twisting two graphene layers forms a moiré pattern, enabling superconductivity. Adding a third, differently twisted layer creates supermoiré patterns, altering electron flow. Harvard SEAS researchers, led by Yonglong Xie and Andrew Pierce, used a 100-nanometer resolution microscope to probe trilayer graphene. Published in Science, their findings reveal novel electronic states, highlighting supermoiré patterns’ role in engineering tunable materials for quantum tec

Scientists at Rice University and University of Houston have developed an innovative, scalable approach to engineer bacterial cellulose into high-strength, multifunctional materials. The study, published in Nature Communications, introduces a dynamic biosynthesis technique that aligns bacterial cellulose fibers in real-time, resulting in robust biopolymer sheets with exceptional mechanical properties.
