An article in Nature presents a conceptually new scanning probe microscope, called a quantum twisting microscope, which enables both momentum-resolved measurements and in situ tuning of the twist angle between 2D materials stacked on top of each other.
Academia can offer a wonderful career path, but the power differentials at play in university life can turn promising careers into nightmares. Academic bullying is an age-old serious issue that affects people in a variety of positions across all branches of science. This Comment discusses how bullying slows the progress of science.
High-performance ferroelectric materials are used in many applications, ranging from actuators to capacitors. Now, high entropy is emerging as an effective and flexible strategy for enhancing the physical properties of ferroelectrics via the delicate design of local polarization configurations.
In Israel, as in most countries, the number of girls who choose to study STEM subjects in high school is still too low, and the number of women occupying leadership positions in academia and tech companies even more so. Neta Blum, a mechanical engineer who founded a programme to inspire female high-school students to choose a path in STEM, argues that mentoring is key to empower the next generation of female scientists and engineers.
An article in Science reports new insight in the formation of defects during 3D printing of metals and presents a highly accurate method to track defects as they form, opening the way for closed-loop control systems.
The transition to climate-friendly cities has led to a renaissance of wood as a renewable building material. To prevent severe raw material shortages in the future, the material-first utilization of wood in long-living, resource-efficient engineered wood products and constructions will be key.
The solutions to many of today’s challenges will be found at the frontier of advanced materials research and will require collaboration across synthesis, characterization, fabrication and theory. While good ideas can be generated anywhere by anyone, scientific opportunities are often concentrated among select groups. National user facilities democratize access to world-class expertise and instrumentation, acting as innovation multipliers on the scientific enterprise.
Peptides are small yet versatile building blocks of biomaterials. This Comment highlights recent progress in the design of liquid-like microdroplets, or coacervates, based on peptides and produced through liquid–liquid phase separation. This emerging platform holds promise as efficacious delivery vehicles for multi-purpose biomedical applications.
Despite concrete being the most prominent building material of the twentieth century, the cultural heritage relevance of concrete buildings and the importance of their preservation is not widely recognized. The European Union project InnovaConcrete’s purpose is to develop nanotechnology-based treatments for concrete preservation and to increase citizen awareness around the importance of concrete-based heritage.
An article in the Journal of Physical Chemistry Letters reports the use of intercalation of Cu or Ag atoms in the 2D magnet CrI3 to obtain 2D multiferroic materials.
An article in Nature Communications sheds light on the influence of the number of layers in the sample on sliding ferroelectricity based on measurements on rhombohedral MoS2.
Efforts to increase diversity in quantum information science education often centre on individual minority students. The co-founder of the IBM-HBCU Quantum Center argues that more resources should go towards faculty enablement strategies targeting schools with a proven track record of graduating minorities in STEM.
