Mica pneumoconiosis. [PDF]

open access: yesOccupational and Environmental Medicine, 1983
Two men developed pneumoconiosis after grinding and packing powdered mica. The disease was characterised by progressive dyspnoea, a restrictive impairment of ventilation, a reduced transfer factor, and hypoxaemia. Radiographs showed widespread fine nodular and linear shadows.

Laboratory Measurements of MICA genetic variants and s-MICA v2 [PDF]

open access: yes, 2019
1. Study design A population-based case-control study of the exocrine pancreas was conducted using incident cases between 20 and 93 years old (mean age = 66 years), diagnosed between 1994 and 1998 in Minnesota. Pancreatic cancer cases (n=163) were ascertained from hospitals, and controls (n=542) were randomly selected from the general population and ...

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

open access: yesAdvanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

A new route of synthesis of Na-Mica-4 from sodalite [PDF]

open access: yes, 2014
Synthesis of Na-Mica-4 has been achieved by a ``mix and calcine¿¿ method using sodalite and magnesium fluoride as the only precursors. Previous research found sodalite as a key intermediate reaction product in the formation of Na-Mica-4 when the NaCl ...

Responsive Polyelectrolyte Brushes in Applications: Functions, Stimuli, and Design Considerations

open access: yesAdvanced Materials, EarlyView.
With advances in the synthesis of polyelectrolyte brushes, these coatings of surface‐grafted chains find uses in an increasing number of applications. This review summarizes three core aspects of these brushes: how they introduce functionality to surfaces; how external stimuli influence their properties; and what practical considerations should be ...
