Single-crystal silicon nanowires with diameters approaching molecular dimensions were
synthesized using gold nanocluster-catalyzed 1D growth. High-resolution transmission …

We report that alkali ions (sodium or potassium) added in small amounts activate platinum
adsorbed on alumina or silica for the low-temperature water-gas shift (WGS) reaction (H 2 O + …

The kagome lattice is a two-dimensional network of corner-sharing triangles 1 that is known
to host exotic quantum magnetic states 2 , 3 , 4 . Theoretical work has predicted that kagome …

Electrocatalytic CO 2 reduction to higher-value hydrocarbons beyond C 1 products is desirable
for applications in energy storage, transportation and the chemical industry. Cu catalysts …

… , the pores expand with a rate that grows with d0, but for d0 < dc the pores con- … a perfect
cylinder, then dc=h, where h is the membrane thickness.[10] Our results indicate that dc ≈ 1/3 h …

Single-source molecular precursors were used to synthesize II−VI compound semiconductor
nanowires for the first time. Cadmium sulfide and zinc sulfide nanowires were prepared …

Iron doping of nickel oxide films results in enhanced activity for promoting the oxygen evolution
reaction (OER). Whereas this enhanced activity has been ascribed to a unique iron site …

Whereas ferromagnets have been known and used for millennia, antiferromagnets were only
discovered in the 1930s 1 . At large scale, because of the absence of global magnetization, …

… Hollow symbols indicate the frequencies obtained from pulsed field measurement, while
filled symbols indicate those obtained from DC field measurement. Different colours indicate …
