With open facilities, the Brazilian Synchrotron Light Laboratory (LNLS) annually welcomes about 1200 Brazilian and foreign researchers, committed to more than 400 studies that result in approximately 200 articles published in scientific journals. Check out below some of the many investigations that have benefited from LNLS facilities.

The research used diamond anvil cells (DAC) together with synchrotron light to investigate superconductors under extreme pressures

Superconductivity was first identified in 1911 by the physicist Heike Kamerlingh Onnes, and is still a significant focus of research in the field of condensed matter physics.

Review article was highlighted in the Applied Physics Reviews journal and explains how computed micro- and nanotomography can be used in fourth-generation synchrotrons like Sirius

Fourth-generation synchrotron light sources like Sirius expand the capacities of x-ray micro- and nanotomography to new levels. A review article written by a team of researchers from the Brazilian Center for Research in Energy and Materials (CNPEM) and the Federal University of ABC and published in Applied Physics Reviews describes recent developments in x-ray computed tomography associated with synchrotron light and artificial intelligence.

Researchers at USP in São Carlos combined cutting-edge technologies and demonstrated that a molecule targeted by medications behaves differently than previously theorized.

A group of researchers from the University of São Paulo in São Carlos has just presented their findings from research indicating a new understanding of the maturation process and how inhibitors act upon the Mpro protein, an essential component in the life cycle of the Sars-CoV-2 virus and the target of various efforts to develop medications to treat Covid-19.

Paper published at Science Magazine investigates unexpected molecular interactions that affect cell function and could cause disease

Cells conduct a series of interconnected biochemical reactions to obtain energy and respond to infections and different stressors. These reactions comprise what are known as metabolic pathways, which interact in complex networks and regulate various cellular processes. Understanding how these networks interconnect and work to regulate cellular processes is a challenge, because this signaling often depends on interactions between proteins and small molecules known as metabolites that involve low-affinity molecular bonds which are extremely difficult to identify.

Review article was highlighted in Chemical Reviews magazine

Originally published by CINE (Center for Innovation on New Energies)   A body of recent research is accelerating the development of perovskite solar cells. These studies monitored, in real time and in detail, the changes that occur in perovskite films during processes that influence their early degradation – one of the main obstacles to the commercialization of this emerging photovoltaic technology.

Experiment carried out on Sirius shed light on reaction fundamental to the production of hydrogen fuel

This text was originally published in Pesquisa FAPESP magazine in January 2023   A recent experiment at Sirius, the Brazilian synchrotron light source at the Brazilian Center for Research in Energy and Materials (CNPEM) in Campinas, São Paulo (see Pesquisa FAPESP issue 269) showed how a certain biological catalyst can more efficiently split water molecules (H2O) using electrolysis. This reaction, an electrochemical process that uses electricity to break down water into the elements that comprise it, is very significant because it produces not only oxygen but also hydrogen, considered the fuel of the future by many specialists because it does not emit any polluting gases when it is utilized (see Pesquisa FAPESP issue 314).

The first scientific paper published with data obtained at the EMA beamline studied the relationship between skutterudite’s superconducting properties and the distance between their atoms.

In Brazil, about 7.5% of the electricity produced is lost in transmission and distribution. This happens because the materials that make up these systems are not perfect electrical conductors and dissipate part of the energy, for example, in the form of heat. Similarly, even though electric cars are much more efficient than combustion-engine vehicles, they can still lose up to 15 percent of their energy during the charging process.

Researchers from CNPEM and collaborators demonstrate the potential of naturally abundant and low-cost minerals for application in nanodevices

The earth's crust consists mostly of minerals called silicates, rocks composed mainly of the chemical elements silicon (Si) and oxygen (O). This is the case of feldspar, whose erosion gives rise to clays; and quartz, the main component of sand, among others. Extremely abundant, silicates are used not only in the production of construction materials, glass, and ceramics, but also in agriculture, and in the pharmaceutical, cosmetic, chemical, and petrochemical industries.

Study elucidates unprecedented processes of herbivore metabolism involved in the efficient degradation of plant fibers

A group of researchers from the Brazilian Biorenewables National Laboratory (LNBR), Brazilian Center for Research in Energy and Materials (CNPEM), an organization supervised by the Brazilian Ministry of Science, Technology and Innovations (MCTI), has published in the journal Nature Communications a study that explores some of the most modern resources of current science to reveal unprecedented and valuable details of the capybara's digestive process.

Paper presents multiscale (nano-micro) FTIR analysis applied to the investigation of the chemical processes in Li-Air batteries

The growing demand for renewable energy sources underscores the urgency of developing new energy storage devices. One example is metal-air batteries, which could be the key to large-scale energy storage. This type of battery is a promising technology for commercial energy storage, as it offers about 10 times the energy density of Li-ion batteries, current market leaders.
