This study examines dissolved rhenium (Re) as a function of water runoff using river samples from two contrasting watersheds, the Eel and Umpqua Rivers in the Pacific Northwest, USA. These watersheds share many key characteristics in terms of size, discharge, climate, and vegetation, but they have a 10-fold difference in...
Mg batteries have potential advantages in terms of safety, cost, and reliability
over existing battery technologies, but their practical implementations are hindered
by the lack of amenable high-voltage cathode materials. The development
of cathode materials is complicated by limited understandings of the unique
divalent Mg²⁺ ion electrochemistry and the interaction/transportation...

In this work the use of linear MOS integrated circuits in the
design of a phase-shift oscillator is presented. By multiplying the
capacitors of the RC feedback network through the use of the Miller
effect, large effective capacitance values are obtained which enable
the low frequency operation of the oscillator....
The mechanism of phosphate adsorption by clay minerals was
reported by Stout. He showed that the loss of water of kaolinite in
the presence of KC1, K₂SO₄ or KH₂PO₄ was due to an exchange reaction
between anion and hydroxyl groups from clay minerals. Also,
Kelly and Midgley reported that the...
Water conservation in nursery systems is an ever-increasing focus, yet there is relatively little guidance for growers producing seedlings intended for restoration regarding how practices such as subirrigation influence plant growth in the nursery and after outplanting. Our study investigated red-flowering currant (Ribes sanguineum Pursh) seedling development and early field...
In this paper, we report a unique property of inactivating Gram-positive/negative bacteria in the dark via apatite-covered Ag/AgBr/TiO2 nanocomposites (AAAT). We demonstrate that the inactivation mechanism is bacteriostatic based on the cellular integrity and motility of bacteria, low toxicity and high durability of AAAT. From straight observations, the catalytic loading...
Carbonatable calcium silicate cement (CSC) is a promising approach to reduce the carbon footprint associated with concrete production. Carbonatable CSC gains strength by reacting with carbon dioxide (CO2). While the concept of carbonation is well known, more information on the curing process is needed. This study focuses on studying the...
