3D Printing of Highly Electrically Conductive Zinc for Sustainable Electronics Applications
A 3D printable zinc ink system with active zinc particles in a shellac matrix is demonstrated. The results show high conductivity, stable performance of printed structures under varying humidity conditions, and promising application in disposable water‐activated batteries. This technology combining digital material assembly, reliable operation, and non‐

A Numerical Study for the Dirichlet Problem of the Helmholtz Equation
In this paper, an effective numerical method for the Dirichlet problem connected with the Helmholtz equation is proposed. We choose a single-layer potential approach to obtain the boundary integral equation with the density function, and then we deal ...

Expert‐led priorities for a response diversity research agenda in ecology
Response diversity describes variation in ecological responses to environmental change. Response diversity is expected to drive ecological stability since a wider variety of responses to one or more environmental factors should stabilise fluctuations of ecosystem functions. However, uptake of empirical response diversity research has been slow. Here we
