Neutron detection is nowadays mostly based on He gas detectors, but its shortage and the continuous upgrades of the neutron facilities require new devices to perform experiments with maximum performances. This work presents a new detector based on the Gas Electron Multiplier (GEM) combined with several boron layers. This detector combines the features of GEM technology with the properties of boron as a neutron converter and the device is produced to sustain high neutron fluxes with high detection efficiency.

Article Synopsis
- Diabetes mellitus increases the risk of cardiovascular disease and is a leading cause of death among patients, impacting cardiac cell mechanics and stiffness.
- The study investigates how Type 1 Diabetes Mellitus (T1DM) alters costameric proteins in heart cells and affects their cellular mechanics using advanced imaging techniques.
- Findings reveal that diabetic cardiomyocytes exhibit higher stiffness compared to normal cells, suggesting that changes in cellular communication may contribute to diabetic cardiomyopathy and affect heart function.
Valorization of residual lignocellulosic biomass in South America: a review.
Environ Sci Pollut Res Int
July 2024
Residual lignocellulosic biomass (RLB) is a valuable resource that can help address environmental issues by serving as an alternative to fossil fuels and as a raw material for producing various value-added molecules. To gain a comprehensive understanding of the use of lignocellulosic waste in South America, a review was conducted over the last 4 years. The review focused on energy generation, biofuel production, obtaining platform molecules (such as ethanol, hydroxymethylfurfural, furfural, and levulinic acid), and other materials of interest.

Article Synopsis
- The study measures the nuclear kinetic energies of hydrogen and oxygen in water molecules as they transition from solid to liquid at specific temperatures (270 K for solid and 276 K for liquid), using neutron Compton profiles in deep inelastic neutron scattering experiments.* -
- It finds similar total kinetic energy values per molecule in both phases (35.3 ± 0.8 kJ/mol for solid, 34.8 ± 0.8 kJ/mol for liquid), aligning with computer simulations and models that suggest minimal difference between the two states through a phase change.* -
- The small variance in nuclear kinetic energy across melting enables simplification in calculating neutron environmental doses in settings like high altitude or polar regions, suggesting that the
