The reaction conditions for the synthesis of Cu-BTC (BTC = benzene-1,3,5-tricarboxylic acid) were elucidated using a continuous-flow microreactor-assisted solvothermal system to achieve crystal size and phase control. A high-rate synthesis of Cu-BTC metal-organic frameworks with BET surface area of more than 1600 m²/g (Langmuir surface area of more than 2000...

A new method was developed for the analysis of natural and synthetic androgenic steroids and their selected metabolites in aquatic environmental matrices using direct large-volume injection (LVI) high performance liquid chromatography (HPLC) tandem mass spectrometry (MS/MS). Method accuracy ranged from 88 to 108% for analytes with well-matched internal standards. Precision,...

Sharp increases in the use of flammable plastics and electronic devices coupled with stricter fire safety requirements have promoted the heavy use of flame retardant chemicals. While flame retardant use has increased, a great deal of uncertainty surrounds their safety with some evidence showing toxicity and risk to human and...

NW Rota-1 is a submarine volcano in the Mariana volcanic arc located ~100 km north of Guam.
Underwater explosive eruptions driven by magmatic gases were first witnessed there in 2004 and continued
until at least 2010. During a March 2010 expedition, visual observations documented continuous but
variable eruptive activity at...

Fungal hyphae are among the most highly polarized cells. Hyphal polarized
growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily
in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex
is required for tethering of secretory vesicles to the apical plasma membrane. We...

Ecological niche models can be a useful tool to identify candidate reintroduction sites for endangered
species but have been infrequently used for this purpose. In this paper, we (1) develop activity-specific
ecological niche models (nesting, roosting, and feeding) for the critically endangered California condor
(Gymnogyps californianus) to aid in reintroduction...

Ligand activation of the aryl hydrocarbon (AHR) has profound effects upon the immunological status of the gastrointestinal tract, establishing and maintaining signaling networks, which facilitate host-microbe homeostasis at the mucosal interface. However, the identity of the ligand(s) responsible for such AHR-mediated activation within the gut remains to be firmly established....

Polycyclic aromatic hydrocarbons (PAHs) are priority environmental contaminants that exhibit mutagenic, carcinogenic, proinflammatory, and teratogenic properties. Oxygen-substituted PAHs (OPAHs) are formed during combustion processes and via phototoxidation and biological degradation of parent (unsubstituted) PAHs. Despite their prevalence both in contaminated industrial sites and in urban air, OPAH mechanisms of action...

We estimate fluid sources around a subducted seamount along the northern Hikurangi subduction
