Advanced Functional Materials, EarlyView.HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Limit theorems for logarithmic means
Journal of Mathematical Analysis and Applications, 1987 The author examines his logarithmic means \[ L_ r(x_ 0,...,x_ n) = \begin{cases} (\int_{A_ n}n!(\sum^{n}_{k=0}x_ kv_ k)^ rdv_ 0...dv_{n-1})^{1/r} & (r\neq 0), \\ \exp\int_{A_ n}n! \log(\sum^{n}_{k=0} x_ kv_ k)dv_ 0... dv_{n-1} & (r=0), \end{cases} \] where \(A_ n=\{(v_ 0,...,v_{n-1}):\) \(0\leq v_ k\leq 1\); \(k=0,...,n-1\); \(0\leq \sum^{n-1}_{k=0}v_ ...

Ehrenfest breakdown of the mean-field dynamics of Bose gases
, 2016 The mean-field dynamics of a Bose gas is shown to break down at time $\tau_h = (c_1/\gamma) \ln N$ where $\gamma$ is the Lyapunov exponent of the mean-field theory, $N$ is the number of bosons, and $c_1$ is a system-dependent constant. The breakdown time

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Advanced Functional Materials, EarlyView.This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Advanced Functional Materials, EarlyView.A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.

Advanced Functional Materials, EarlyView.Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...
