Thermochemical Material Systems for Heating Ventilation and Air Conditioning
A thermal energy storage (TES) system using a thermochemical material (TCM) may have a discharging mode (i.e., heat releasing mode) and a charging mode (i.e., heat absorbing mode), both of which can be used in building heating, ventilation, and air conditioning (HVAC) applications. During both modes, the water vapor/moisture contained in the air interacts with the TCM. During discharging, water vapor is absorbed by the TCM and the heat of reaction is released to the air, resulting in a substantially dehumidified air which may be slightly heated and can be used for heating applications. During charging, the TCM may be heated to drive the reversible dehydration reaction and release the moisture to the air, preparing it for cooling applications.

Excess phosphorus (P) in wastewater effluent poses a serious threat to aquatic ecosystems and can spur harmful algal blooms. Revolving algal biofilm (RAB) systems are an emerging technology to recover P from wastewater before discharge into aquatic ecosystems. In RAB systems, a community of microalgae take up and store wastewater P as polyphosphate as they grow in a partially submerged revolving biofilm, which may then be harvested and dried for use as fertilizer in lieu of mined phosphate rock. Disclosed herein are methods for isolating and characterizing microalgae strains from active RAB systems. Strains were identified by microscopy and 16S/18S ribosomal DNA sequencing, cryopreserved, and screened for elevated P content (as polyphosphate). Seven isolated strains possessed at least 50% more polyphosphate by cell dry weight than a microalgae consortium from a RAB system, with the top strain accumulating nearly threefold more polyphosphate. Isolated P-hyperaccumulating microalgae have broad applications in resource recovery from various waste streams, including improving P removal from wastewater.

CONTROL OF SURFACE MORPHOLOGY DURING THE GROWTH OF (110)-ORIENTED GAAS BY HYDRIDE VAPOR PHASE EPITAXY
Disclosed herein are methods for the growth of (110) GaAs solar cells by hydride vapor phase epitaxy (HVPE) as an advance towards a (110)-oriented device platform with substrate reuse via spalling.

Spalling of (110)-oriented substrates takes advantage of the natural (110) cleavage plane in zinc-blende III-V materials, eliminating this faceting.
