Real‐Time, Label‐Free Monitoring of Cell Behavior on a Bioelectronic Scaffold
A bioelectronic nanofibrous scaffold is introduced that supports cell growth while enabling real‐time, label‐free monitoring of cellular behavior through impedance measurements. The system correlates electrical signals with cell viability and surface coverage, offering an integrated platform for studying dynamic biological processes and advancing next ...

Asymptotically linear Schrödinger–Poisson systems with potentials vanishing at infinity
The author studies the Schrödinger-Poisson system \[ \begin{cases} -\Delta u+V(x)u+\lambda\varphi(x)u= K(x)f(u),\quad x\in{\mathbb R}^3, \\ -\Delta\varphi=u^2, \lim\limits_{|x|\to\infty} \varphi(x)=0, \end{cases} \] where \(\lambda > 0\) is a parameter, the potential \(V(x)\) is continuous, radial and may be vanishing at infinity, \(f(s)\) is ...

Self‐Refreshing Bi‐Based Active Sites for Efficient and Durable Electrochemical CO2 Reduction
A self‐refreshing Bi‐based catalyst is developed through the fabrication of a novel basic bismuth nitrate pre‐catalyst, which exhibits differential active sites of Bi2O2CO3 at low potentials and metallic Bi phases at high potentials, self‐repairing capability, and thus wide‐potential‐window efficiency and ultralong durability toward electrochemical CO2

Predicting Atomic Charges in MOFs by Topological Charge Equilibration
An atomic charge prediction method is presented that is able to accurately reproduce ab‐initio‐derived reference charges for a large number of metal–organic frameworks. Based on a topological charge equilibration scheme, static charges that fulfill overall neutrality are quickly generated.

Superradiant bound states of charged scalars around Melvin-Kerr black holes
We investigate superradiant bound states of a charged, massive scalar in the Melvin-Kerr spacetime, a rotating black hole immersed in an external magnetic field, working in the weak-field regime bM≪1.

Chiral SURMOFs for Vibrational Circular Dichroism: Multiscale Modeling and Experimental Insights
The use of solid‐state vibrational circular dichroism (VCD) for MOFs is still somewhat unexplored, and in this work, it is shown that chiral surface‐anchored MOFs (SURMOFs) grown on CaF2 provide an excellent platform for VCD. Experimental results are validated through multiscale modeling, showing strong agreement across multiple spectroscopic ...

Bounded and large radially symmetric solutions for some (p,q)-Laplacian stationary systems
This article concerns radially symmetric positive solutions of second-order quasilinear elliptic systems. In terms of the growth of the variable potential functions, we establish conditions such that the solutions are either bounded or blow up at ...

Surface Diffusion in SnTe‐PbTe Monolayer Lateral Heterostructures
The lateral heterostructures between 2D materials often suffer from the interdiffusion at the interfaces. Here, a surface diffusion mechanism is found to be dominating at the interfaces between semiconducting SnTe and PbTe monolayers. Atomically sharp interfaces can be achieved by suppressing this diffusion process. ABSTRACT The construction of complex

A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

New Periodic Solutions for the Singular Hamiltonian System
By use of the Cerami-Palais-Smale condition, we generalize the classical Weierstrass minimizing theorem to the singular case by allowing functions which attain infinity at some values. As an application, we study certain singular second-order Hamiltonian
