Exposure to polybrominated diphenyl ethers (PBDEs) suppresses the release of pro-inflammatory products by alveolar macrophages in vitro [PDF]

open access: yes, 2010
Endocrine disrupting chemicals have adverse effects on immune function that may result in respiratory conditions. Inhalation of dust is a major route of exposure to PBDEs; however, the impact of PBDEs on the immune response is unclear.

High throughput synthesis of 2,5-substituted indoles using a titanium carbenoid bearing boronate functionality [PDF]

open access: yes, 2008
A titanium benzylidene complex bearing a boronate group converted resin-bound esters into enol ethers. Suzuki cross-coupling with aryl iodides followed by cleavage with acid completed the solid-phase synthesis of 2,5-disubstituted N-Boc-indoles.

Photothermal Macroporous Lignin Cryogels for Off‐Grid, Continuous Atmospheric Water Collection via Interlayer Heat Recovery

open access: yesAdvanced Functional Materials, EarlyView.
Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.
