Tracing the phase transition of Al-bearing species from molecules to dust in AGB winds. Constraining the presence of gas-phase (Al2O3)n clusters [PDF]
A&A 608, A55 (2017), 2017 (abbreviated) We aim to constrain the dust formation histories in the winds of oxygen-rich AGB stars. We have obtained ALMA observations with a spatial resolution of 120x150 mas tracing the dust formation region of a low mass-loss rate and a high mass-loss rate AGB star, R Dor and IK Tau.

Nonlinear Short-term Prediction of Aluminum Foil Thickness via Global Regressor Combination
Applied Artificial Intelligence, 2017 In this study, short-term prediction of aluminum foil thickness time-series data recorded during cold-rolling process was investigated. The locally projective nonlinear noise reduction was applied in order to improve the predictability of the time series.

Breast cysts and aluminium-based antiperspirant salts [PDF]
, 2019 On the basis that aluminium-based antiperspirant salts are designed to block apocrine sweat ducts of the axilla, and that breast cysts result from blocked breast ducts in the adjacent region of the body, it has been proposed that breast cysts may arise ...

Solid-state NMR characterisation of the thermal transformation of a Hungarian white illite [PDF]
, 2005 1H, 27Al, 29Si and 39K solid-state NMR are reported from a Hungarian illite 2:1 clay for samples heated up 1600 °C. This single-phase sample has a small amount of aluminium substitution in the silica layer and very low iron-content (0.4 wt%).
