Particulate collector

open access: yes, 2008
The goal of this work was to manufacture and to analyze a passive device performance (inertial collector). This one has worked as an opening for the inside ambient natural airing and also it retains some particulate material present in the air which passes through it. The collector work has been based in the inertia which each particle has, that is, as

The low-temperature geochemical cycle of iron: From continental fluxes to marine sediment deposition [PDF]

open access: yes, 2002
Suspended sediments from 34 major rivers (geographically widespread)and 36 glacial meltwater streams have been examined for their variations in different operationally-defined iron fractions; FeHR (iron oxides soluble in dithionite), FePR (iron soluble ...

Investigation into dustiness on Veisiejai-Viktarinas-Paliepiai gravelled road treated with calcium chloride

open access: yesMokslas: Lietuvos Ateitis, 2011
The main problem related to gravelled roads is their dustability during the warm season of the year. Bituminous emulsion and calcium chloride are among the most popular and widespread materials used to reduce dustiness in Lithuania.

Investigations on tensile fractography and wear characteristics of Al7075-Al2O3-SiC Hybrid Metal Matrix Composites routed through liquid metallurgical techniques

open access: yesFracture and Structural Integrity, 2021
The Al2O3-SiC reinforced Al7075 Metal Matrix Composite (MMCs) is fabricated through liquid metallurgical technique. Ceramic particulates were amalgamated into the aluminium alloy to achieve improved mechanical properties and wear resistance.

Evolution of ozone, particulates, and aerosol direct radiative forcing in the vicinity of Houston using a fully coupled meteorology‐chemistry‐aerosol model

open access: yes, 2006
[1] A new fully coupled meteorology-chemistry-aerosol model is used to simulate the urban- to regional-scale variations in trace gases, particulates, and aerosol direct radiative forcing in the vicinity of Houston over a 5 day summer period.

Fabrication of metal matrix composites under intensive shearing [PDF]

open access: yes, 2008
Current processing methods for metal matrix composites (MMC) often produces agglomerated reinforced particles in the ductile matrix and also form unwanted brittle secondary phases due to chemical reaction between matrix and the reinforcement. As a result
