Dual-Responsive Hydrogels with Three-Stage Optical Modulation for Smart Windows.

Since room temperature management consumes a large amount of building energy, thermochromic smart windows have been extensively used for temperature regulation and energy management. However, the development of the smart window is still limited by its simple thermochromic performance, unreasonable thermochromic temperature, and the lack of additional stimulation conditions. In this work, a dual-responsive hydrogel was developed by introducing sodium dodecyl sulfate (SDS) and sodium chloride into the cross-linking network of poly(-isopropylacrylamide) (PNIPAM) and polyacrylamide (PAM) for energy-saving and privacy protection.

The Nitrogen-Removal Efficiency of a Novel High-Efficiency Salt-Tolerant Aerobic Denitrifier, HRL-9, Isolated from a Seawater Biofilter.

Aerobic denitrification microbes have great potential to solve the problem of NO-N accumulation in industrialized recirculating aquaculture systems (RASs). A novel salt-tolerant aerobic denitrifier was isolated from a marine recirculating aquaculture system (RAS) and identified as HRL-9. Its aerobic denitrification performance in different dissolved oxygen concentrations, temperatures, and C/N ratios was studied.

Preparation of thermoresponsive alginate/starch ether composite hydrogel and its application to the removal of Cu(II) from aqueous solution.

A novel polysaccharide-based thermoresponsive hydrogel containing sodium alginate (SA) and 2-hydroxy-3-isopropoxypropyl starch (HIPS) was developed for removing Cu(II) from aqueous solution. HIPS/SA hydrogel showed network and porous structure, as well as the abundant carboxy groups inside the structure, endowed it with sufficient binding sites for adsorption of Cu(II). The reversible thermoresponsive swelling-shrinking behavior of HIPS/SA hydrogel was discussed.

Thermoresponsive 2-hydroxy-3-isopropoxypropyl hydroxyethyl cellulose with tunable LCST for drug delivery.

Thermoresponsive polymer 2-hydroxy-3-isopropoxypropyl hydroxyethyl celluloses (HIPECs) were successfully synthesized, characterized, and applied for thermoresponsive drug delivery. The lower critical solution temperature (LCST) of HIPEC could be easily tuned from 21.1 to 56.
