Characteristics of brown carbon in the urban Po Valley atmosphere [PDF]

Atmospheric Chemistry and Physics, 2017
We investigate optical–microphysical–chemical properties of brown carbon (BrC) in the urban ambient atmosphere of the Po Valley. In situ ground measurements of aerosol spectral optical properties, PM1 chemical composition (HR-ToF-AMS), and particle size ...

Discordance Between Patient and Physician Global Assessments in Early Systemic Sclerosis

Arthritis Care &Research, EarlyView.
Objective This study aims to identify factors associated with patient global assessment (PtGA) and physician global assessment (PhGA) and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (<5 years) from the Collaborative National Quality and Efficacy Registry were included.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Evolution of the breeding range of the “italian” Wagtail Motacilla flava cinereocapilla

Rivista Italiana di Ornitologia - Research in Ornithology, 2016
[The paper shows the evolution of the breeding distribution of the Ashy-headed Wagtail Motacilla flava cinereocapilla in the period 1820-2014. Until 1880, the subspecies nested along the coast north and east of the Adriatic Sea, with some settlements ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Ozone source attribution in polluted European areas during summer 2017 as simulated with MECO(n) [PDF]

Atmospheric Chemistry and Physics
Emissions of land transport and anthropogenic non-traffic emissions (e.g. industry, households and power generation) are significant sources of nitrogen oxides, carbon monoxide and volatile organic compounds (VOCs).

Transport of Po Valley aerosol pollution to the northwestern Alps – Part 1: Phenomenology [PDF]

Atmospheric Chemistry and Physics, 2019
Mountainous regions are often considered pristine environments; however they can be affected by pollutants emitted in more populated and industrialised areas, transported by regional winds.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Chemical characterization of springtime submicrometer aerosol in Po Valley, Italy [PDF]

Atmospheric Chemistry and Physics, 2012
The chemistry of submicron particles was investigated at San Pietro Capofiume (SPC) measurement station in the Po Valley, Italy, in spring 2008. The measurements were performed by using both off-line and on-line instruments.

PALEOCLIMATE AND PALEOENVIRONMENT IN NORTH-WESTERN ITALY (SOUTHERN ALPS) DURING THE LAST GLACIAL STAGE: THE SMALL-MAMMAL RECORD FROM THE BUCO DEL FRATE CAVE (PREVALLE – BRESCIA)

Rivista Italiana di Paleontologia e Stratigrafia, 2023
The palaeoclimatic and palaeoenvironmental data obtained by the study of the Buco del Frate cave small-mammals indicate that, around 40,000 years ago (MIS3), the eastern part of the province of Brescia, immediately to the west of Lake Garda, was ...
