Solution and on-surface synthesis of structurally defined graphene nanoribbons as a new family of semiconductors
Graphene nanoribbons (GNRs) with various structures and properties can be synthesized in solution or on surface.
Core-dependent properties of copper nanoclusters: valence-pure nanoclusters as NIR TADF emitters and mixed-valence ones as semiconductors
While valence-pure copper alkynyl nanoclusters show near-infrared TADF, the mixed-valence ones exhibit semiconductivity.
Photon upconversion utilizing energy beyond the band gap of crystalline silicon with a hybrid TES-ADT/PbS quantum dots system
Photon upconversion with an excitation of energy below the band gap of crystalline silicon was demonstrated with a hybrid system consisting of molecules based on a thiophene conjugated acene (i.e., TES-ADT) and lead sulphide (PbS) quantum dots.
Emergence of high ORR activity through controlling local density-of-states by alloying immiscible Au and Ir
Although Ir or Au is not active for ORR, we first demonstrate highly active Au0.5Ir0.5 alloy by emulating Pt LDOS profile.
Photon-upconverting chiral liquid crystal: significantly amplified upconverted circularly polarized luminescence
By blending a chiral acceptor and a sensitizer into a nematic liquid crystal, a chiral nematic liquid crystal showing amplified upconverted circularly polarized luminescence could be obtained.

Identifying key descriptors in surface binding: interplay of surface anchoring and intermolecular interactions for carboxylates on Au(110)
The relative stability of carboxylates on Au(110) was investigated as part of a comprehensive study of adsorbate binding on Group IB metals that can be used to predict and understand how to control reactivity in heterogeneous catalysis.
Trends in activity for the oxygen evolution reaction on transition metal (M = Fe, Co, Ni) phosphide pre-catalysts
A notable trend in OER activity on transition metal phosphide pre-catalysts is reported. Remarkably, the tri-metallic FeCoNiP pre-catalysts exhibit exceptional apparent and intrinsic OER activities, outperforming many non-precious OER catalysts reported previously.
Polyhedral Cu2O to Cu pseudomorphic conversion for stereoselective alkyne semihydrogenation
Cu2O nanocrystals can be pseudomorphically converted into Cu crystals through ammonia borane reduction, releasing hydrogen for stereoselective semihydrogenation of diphenylacetylene.
