Novel membranes are fabricated for use in desalination and water purification applications by F. Caruso, S. E. Kentish, and co-workers, described on page 2791. The crosslinked polyelectrolyte multilayer membranes are synthesized on a porous polysulfone support within aqueous media and are crosslinked with glutaraldehyde. This leads to NaCl rejections of up to 97%. The incorporation of a highly sulfonated polysulfone polyanion results in outstanding chlorine resistance.

Multifunctional optoelectronic devices, which use photons to communicate and electrons to process and store the data, are considered as emerging candidates for the next generation of information technology. The work presented by G. Liu, R.-W. Li, and co-workers on page 2797 reports the design and construction of an optoelectronic resistive switching memory, with integrated optical information demodulating and computing functions in an indium tin oxide (ITO)/CeO2−x/AlOy/Al multilayer structure, which demonstrates promising information processing and storage capabilities.
- 2D Materials: The Influence of Water on the Optical Properties of Single-Layer Molybdenum Disulfide (Adv. Mater. 17/2015) (page 2733)

A scanning probe image of single-layer MoS2 trapping water on a mica surface is depicted on the left, with its corresponding photoluminescence image depicted on the right. The trapped water strongly quenches the fluorescence of single-layer MoS2 and distinctly affects its optical properties. The work by J. R. Heath and co-workers on page 2734 highlights the significance of the local chemical environment in determining the opto-electronic properties of 2D materials.
- Upconversion Lasers: Stable and Low-Threshold Optical Gain in CdSe/CdS Quantum Dots: An All-Colloidal Frequency Up-Converted Laser (Adv. Mater. 17/2015) (page 2678)

An all-colloidal vertical-cavity surface-emitting laser (VCSEL) is reported by C. Dang, H. Sun, H. V. Demir and co-workers on page 2741, which offers high performance and stability while being fully solution processed. This all-colloidal laser is based on a stacked architecture of dielectric mirrors, based on metal oxide nanoparticles sandwiching semiconductor nanocrystals as the optical gain medium, forming an all-solution-processed VCSEL structure. Here, using tailored core-shell quantum dots that have suppressed non-radiative Auger recombination enables the achievement of sub-mJ cm−2 frequency up-converted lasing thresholds, which make these all-colloidal devices highly promising for optoelectronic and biomedical applications.
