Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.

Cu+‐Driven Formate Selectivity in Oxidation‐State‐Dependent CO2 Reduction on Cu2O|Graphene

Small, EarlyView.
A Cu2O|graphene heterostructure enables interfacial electronic self‐regulation that stabilizes catalytically active Cu+ species under cathodic CO2 reduction conditions. Suppressed over‐reduction preserves structural integrity and promotes *OCHO pathway, resulting in durable and highly selective electrochemical conversion of CO2 to formate.

Electrochemical and Biological Evaluation of Patterned TiO2@TiC‐Nanowires for Bio‐Interface Electrode

Small, EarlyView.
This study introduces a room‐temperature process to fabricate patterned TiO2@TiC core–shell nanowires, merging the biocompatibility of TiO2‐NWs with the high conductivity of TiC. Through sputtering pressure and time modulation, the nanowires morphology and electrochemical properties are tuned, enabling enhanced capacitance, stability, and guided ...

Self‐Assembly of Hierarchically Structured Materials From Liquid Crystalline Mesophases of Tobacco Mosaic Virus‐Like Particles

Small, EarlyView.
Recombinantly produced Tobacco Mosaic Virus coat protein (TMVcp) helical rods were demonstrated to reproducibly self‐assemble into hierarchically structured macroscopic filaments, driven by a lyotropic liquid crystal (LC) intermediate phase. The results indicate anisotropic molecular alignment of the fluid phase, retention of the native secondary ...

Scalable Room‐Temperature Terahertz Graphene Cameras

Small Methods, EarlyView.
ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Wave‐Velocity‐Based Temperature Monitoring Applied to Underground Power Cables in Medium‐Voltage Networks—Discrimination of Individual Cable Temperatures in a Distribution Grid

High Voltage, EarlyView.
ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

An Improved Method for Calculating the Radiative Cooling Heat Dissipation Power of an Oil‐Natural‐Air‐Natural Transformer

High Voltage, EarlyView.
ABSTRACT Radiative cooling holds potential for outdoor transformers in operation due to its zero‐energy consumption and high adaptability and has demonstrated effective heat dissipation in simulations of small distribution transformers. Accurate calculation of the transformer temperature rise and the radiative cooling effect is crucial for practical ...
