We propose a family of structures that have “Dirac loops,” closed lines of Dirac nodes in
momentum space, on which the density of states vanishes linearly with energy. Those …

Helices are the most prevalent secondary structure in biomolecules and play vital roles in
their activity. Chemists have been fascinated with mimicking this molecular conformation …

The development of new polymerization reactions is of critical importance to macromolecule
science. In this critical review, we summarize the research efforts to incubate alkyne–azide …

Copper nanoparticles have been explored as a new class of heterogeneous catalyst in
various chemical transformations. This review surveys the most useful organic …

The evolution of chemistry in the last 60 years can be illustrated by the introduction of just a
few new concepts. One is macromolecules,(1, 2) whose importance was recognized in the …

There is a great demand for long-term cellular tracers because of their great importance in
monitoring biological processes, pathological pathways, therapeutic effects, etc. Herein we …

The development of mechanophores as building blocks that serve as predefined weak
linkages has enabled the creation of mechanoresponsive and mechanochromic polymer …

During cellulose dissolution in non-derivatizing solvents, the inter-and intramolecular
hydrogen bonds of the polymer are deconstructed. This occurs either by hydrogen bond …

Aggregation-induced emission (AIE) is a newly developed phenomenon that is exactly
opposite to the aggregation-caused emission quenching effect observed with some …

Specific bioprobes with fluorescence turn-on response are highly desirable for high contrast
biosensing and imaging. In this work, we developed a new generation bioprobe by …
