Advanced Functional Materials, EarlyView.Ar–H2 annealing triggers redistribution of pre‐deposited Pt single atoms (SAs) on faceted anatase nanosheets, with selective SAs accumulation on the minor (101) facetsthus the co‐catalytic SA‐sites are positioned only where they are needed, i.e. at the electron exit facets.

arXiv, 2006 The case for substantial far infrared ice emission in local ultraluminous infrared galaxies, expected based on the presence of mid-infrared ice absorption in their spectra and the known far infrared optical properties of ice, is still largely unsupported by direct observation owing to insufficient far infrared spectral coverage.

Selective absorbers and thermal emitters for far-infrared wavelengths
, 2015 We demonstrate engineered selective absorption and subsequent selective thermal emission from sub-wavelength thickness optical structures at far-infrared (30–40 μm) wavelengths.

Advanced Functional Materials, EarlyView.In this article, a water‐evaporation driven energy harvester is devised that works even in the absence of sunlight. This is achieved by combining PVA hydrogel with thermoelectrics (TEG) to directly capture energy from water evaporation. Under mild conditions (RH 40%, T of 26 °C, and 2.8 m s−1 wind), 1.71 mW (1.02 W m−2) power can be generated, >3 fold ...

Advanced Functional Materials, EarlyView.A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

Far-infrared graphene plasmonic crystals for plasmonic band engineering.
Nano letters (Print), 2014 We introduce far-infrared graphene plasmonic crystals. Periodic structural perturbation-in a proof-of-concept form of hexagonal lattice of apertures-of a continuous graphene medium alters delocalized plasmonic dynamics, creating plasmonic bands in a ...
