Nanotechnology discovery unlocks unique molecular interactions using light

2024-12-28 - 2024-12

Researchers at the University of Bologna, led by Prof. Alberto Credi, have developed an innovative method to manipulate molecular assembly using light energy. This approach allows for the creation of a molecular configuration that defies the natural thermodynamic equilibrium, a feat previously considered unattainable.
"We have shown that by administering light energy to an aqueous solution, a molecular self-assembly reaction can be prevented from reaching a thermodynamic minimum, resulting in a product distribution that does not correspond to that observed at equilibrium," says Alberto Credi.

"Such a behavior, which is at the root of many functions in living organisms, is poorly explored in artificial molecules because it is very difficult to plan and observe. The simplicity and versatility of our approach, together with the fact that visible light - i.e., sunlight - is a clean and sustainable energy source, allow us to foresee developments in various areas of technology and medicine."


A New Frontier in Nanotechnology
Nanotechnology relies heavily on the self-assembly of molecular components to form nanometer-scale systems and materials. Typically, these processes strive for a state of thermodynamic equilibrium, or minimum energy. However, living organisms rely on chemical processes that occur outside equilibrium, sustained by external energy. Reproducing these complex mechanisms in artificial systems could open doors to revolutionary applications such as smart drugs and responsive materials.

Using XRD for Structural Analysis in Nanomaterials

2025-01-03 - 2025-01

X-ray diffraction (XRD) is a non-destructive analytical technique used to determine the atomic and molecular structure of materials by measuring how X-rays scatter. It provides key information about a material's phases, crystalline structure, average crystallite size, strain, orientation, texture, and defects.1 XRD is widely applied in nanomaterial science for structural characterization.

Principle of XRD
XRD works by directing X-rays onto a crystalline material and analyzing the angles and intensities of the diffracted beams. The atomic planes within the crystal act as a three-dimensional grating, scattering the X-rays in specific directions. This scattering produces a unique diffraction pattern consisting of intense spots known as Von Laue or Bragg diffraction spots.1-2

The diffraction pattern provides crucial structural information, including the material's symmetry, orientation, and phase. The relationship between the incident X-rays and the atomic planes is governed by Bragg’s Law, expressed as:

2d sin? = n?

Where:

n is an integer representing the diffraction order.
? is the wavelength of the incident X-rays.
d is the interplanar spacing in the crystal.
? is the angle of incidence of the X-rays.
When the conditions of Bragg’s Law are satisfied, constructive interference occurs, producing the diffraction peaks observed in the XRD pattern. By analyzing these peaks, the interplanar spacing d can be calculated, providing insight into the crystal structure.1-2

An XRD diffractogram represents the intensity of diffracted X-rays as a function of the diffraction angle 2?. Each peak corresponds to a specific set of crystallographic planes, allowing researchers to identify the crystal structure and phase composition by comparing the pattern to reference databases such as the International Crystallographic Diffraction Data (ICDD).2

In addition to phase identification, XRD can measure lattice parameters and detect crystal imperfections, including strain, dislocations, and stacking faults.2 These insights are important for analyzing the structural properties of crystalline materials, establishing XRD as a widely used tool in nanomaterial science.

Successfully Developed a Method for Doping Semiconductor Nanocrystals, Synthesizing Next-Generation Semiconductor Nanomaterials from the Seed Phase to the Future!

2025-01-06 - 2025-01

Professor Jiwoong Yang and his research team at the Department of Energy Science and Engineering, Daegu Gyeongbuk Institute of Science & Technology (DGIST; President Kunwoo Lee) successfully developed a new technology to control doping at the nucleus (seed) phase to increase the performance of semiconductor nanocrystals. This study was conducted in collaboration with a research team led by Stefan Ringe at the Department of Chemistry, Korea University (Dongwon Kim). The research uncovered how the doping process and location differ depending on the type of doping element (dopant). The developed technology is expected to be widely utilized in advanced electronic devices, such as displays and transistors.



? With the rapid development of advanced technologies in recent years, such as displays and transistors, interest in technologies that can precisely control doping in nanoscale semiconductors is growing. In particular, II-VI semiconductor-based nanocrystals have been widely studied owing to their outstanding optical and electrical properties.



? While doping plays a critical role in semiconductor technology, the problem of low doping efficiency in small semiconductors, such as nanocrystals, remains. This problem arises because dopants tend to be absorbed onto the surface of a semiconductor during its growth and do not penetrate its interior effectively. In this context, Professor Yang’s research team developed a controlled nucleation doping method, which induces doping at the “nanocluster” phase, a stage preceding nanocrystal growth. Using this technique, the team successfully implemented stable and precise doping in ZnSe semiconductor nanocrystals and identified the reasons behind the variations in doping processes and locations depending on the dopant type.



? Although previous studies on doping II-VI semiconductor nanocrystals have mainly used CdSe, a heavy metal, Cd is harmful to the environment and has poor stability. This study developed a technology applicable to nanocrystals that eliminates the use of heavy metals, demonstrating its potential for practical applications while also addressing environmental concerns. In addition, the study demonstrated the technology’s applicability across various electronic devices, such as displays and transistors.



? Professor Yang said, “This research has enabled us to systematically establish doping control technology in nanocrystals. The findings will not only serve as important foundational data for designing and fabricating optoelectronic devices, such as next-generation displays and transistors, but also open up new possibilities for designing innovative devices through precise doping control technology.”



? The study was funded by the National Research Foundation of Korea’s Excellent New Research Project, the Ministry of Trade, Industry and Energy’s Korea-US International Joint Technology Development Project, and the DGIST Sensorium Institute. The findings were publ

Pioneers in nanotechnology in Milestones in the development of nanotechnology

2025-01-06 - 2025-01



A number of key technological milestones have been achieved by working pioneers. Molecular beam epitaxy, invented by Alfred Cho and John Arthur at Bell Labs in 1968 and developed in the 1970s, enabled the controlled deposition of single atomic layers. This tool provided for nanostructuring in one dimension as atomic layers were grown one upon the next. It subsequently became important in the area of compound semiconductor device fabrication. For example, sandwiching one-nanometre-thick layers of nonmagnetic-sensor materials between magnetic layers in computer disk drives resulted in large increases in storage capacity, and a similar use of nanostructuring resulted in more energy-efficient semiconductor lasers for use in compact disc players.

In 1981 Gerd Binnig and Heinrich Rohrer developed the scanning tunneling microscope at IBM’s laboratories in Switzerland. This tool provided a revolutionary advance by enabling scientists to image the position of individual atoms on surfaces. It earned Binnig and Rohrer a Nobel Prize in 1986 and spawned a wide variety of scanning probe tools for nanoscale observations.

The observation of new carbon structures marked another important milestone in the advance of nanotechnology, with Nobel Prizes for the discoverers. In 1985 Robert F. Curl, Jr., Harold W. Kroto, and Richard E. Smalley discovered the first fullerene, the third known form of pure carbon (after diamond and graphite). They named their discovery buckminsterfullerene (“buckyball”) for its resemblance to the geodesic domes promoted by the American architect R. Buckminster Fuller. Technically called C60 for the 60 carbon atoms that form their hollow spherical structure, buckyballs resemble a football one nanometre in diameter (see figure). In 1991 Sumio Iijima of NEC Corporation in Japan discovered carbon nanotubes, in which the carbon ringlike structures are extended from spheres into long tubes of varying diameter. Taken together, these new structures surprised and excited the imaginations of scientists about the possibilities of forming well-defined nanostructures with unexpected new properties.

The scanning tunneling microscope not only allowed for the imaging of atoms by scanning a sharp probe tip over a surface, but it also allowed atoms to be “pushed” around on the surface. With a slight bias voltage applied to the probe tip, certain atoms could be made to adhere to the tip used for imaging and then to be released from it. Thus, in 1990 Donald Eigler spelled out the letters of his company’s logo, IBM, by moving 35 xenon atoms into place on a nickel surface. This demonstration caught the public’s attention because it showed the precision of the emerging nanoscale tools.

The system was developed by a team led by Kelvin Fu from the University of Delaware and Feng Jiao from Washington University, both US. Electrolysis first reduces the carbon dioxide into carbon monoxide. This is then channelled into a thermochemical reactor where a steel wool catalyst converts it into carbon nanotubes. The nanotubes are then used in a 3D-printing process to create high-quality thermoset carbon nanocomposites.

Sustainable Future for Carbon Nanotubes

2025-01-15 - 2025-01


This finding positions CNT fibers as a sustainable alternative to traditional materials such as metals, polymers, and larger carbon fibers, which are challenging to recycle.

Recycling has long been a challenge in the materials industry—metals recycling is often inefficient and energy intensive, polymers tend to lose their properties after reprocessing, and carbon fibers cannot be recycled at all, only downcycled by chopping them up into short pieces.

Matteo Pasquali, A.J. Hartsook Professor of Chemical and Biomolecular Engineering, Materials Science and NanoEngineering and Chemistry, Rice University

He added, “As CNT fibers are being scaled up, we asked whether and how these new materials could be recycled in the future so as to proactively avoid waste management problems that emerged as other engineered materials reached large-scale use. We expected that recycling would be difficult and would lead to significant loss of properties. Surprisingly, we found that carbon nanotube fibers far exceed the recyclability potential of existing engineered materials, offering a solution to a major environmental issue.”

Using chlorosulfonic acid, a common industrial solvent, the team dissolved fiber-grade commercial CNTs to produce solution-spun CNT fibers. Evaluating the impact of different material sources on the fiber manufacturing process and fiber properties was important, as end-of-life recycling often involves combining materials from various manufacturers using different production methods.
