TREND: NATURALNESS HITS A SNAG WITH HIGGS

Redazione
(AGENPARL) – WASHINGTON (D.C.), mer 25 novembre 2020 One possibility is that symmetries are still at play but in an unexpected form. In this case, the unexpected symmetry relates the standard model to an identical twin, which has its own particles and interactions that are mirror reflections of those in......

PLASTIC POLLUTION IS EVERYWHERE. STUDY REVEALS HOW IT TRAVELS

Redazione
(AGENPARL) – WORCESTER (MASSACHUSETTS), sab 14 novembre 2020 Plastic pollution is ubiquitous today, with microplastic particles from disposable goods found in natural environments throughout the globe, including Antarctica. But how those particles move through and accumulate in the environment is poorly understood. Now a Princeton University study has revealed the......

RESEARCHERS 3D PRINT BIOMEDICAL PARTS WITH SUPERSONIC SPEED

Redazione
(AGENPARL) – WORCESTER (MASSACHUSETTS), mar 10 novembre 2020 Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed. This form of technology, known as “cold spray,” results in......

STUDY MEASURES EFFECTIVENESS OF DIFFERENT FACE MASK MATERIALS WHEN COUGHING

Redazione
(AGENPARL) – CAMBRIDGE (ENGLAND), ven 30 ottobre 2020 The researchers, from the University of Cambridge and Northwestern University, tested the effectiveness of different fabrics at filtering particles between 0.02 and 0.1 micrometres – about the size of most viruses – at high speeds, comparable to coughing or heavy breathing. They......

SIMULATIONS OF STRUCTURE FORMATION BY CONFINED DIPOLAR ACTIVE PARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 20 ottobre 2020 Dipolar active particles describe a class of self-propelled, biological or artificial particles equipped with an internal (typically magnetic) dipole moment. Because of the interplay between self-propulsion and dipole–dipole interactions, complex collective behavior is expected to emerge in systems of such particles.......

FURTHER INSIGHTS INTO THE FE(II) REDUCTION OF 2-LINE FERRIHYDRITE: A SEMI IN SITU AND IN SITU TEM STUDY

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), gio 01 ottobre 2020 The biotic or abiotic reduction of nano-crystalline 2-line ferrihydrite (2-line FH) into more thermodynamically stable phases such as lepidocrocite-LP, goethite-GT, magnetite-MG, and hematite-HT plays an important role in the geochemical cycling of elements and nutrients in aqueous systems. In our study,......
