Power Generation Efficiency of Intelligent Intermittent Distributed Photovoltaic Systems at Well Sites

open access: yesShiyou jixie
The power generation of a well-site photovoltaic (PV) power station is closely related to its revenue, and its generating capacity depends on many factors, such as the station design, module performance and system condition. A scientific evaluation of PV

Power enhancement in PV arrays under partial shaded conditions with different array configuration

open access: yesHeliyon
Solar Photovoltaic systems are used for electrical power generation, and they provide an alternative source to non-renewable energy sources like coal, oil, natural gas and nuclear energy. Photovoltaic arrays used in PV systems may be subjected to partial

Distinct mutational signatures characterize concurrent loss of polymerase proofreading and mismatch repair

open access: yesNature Communications, 2018
Polymerase proofreading and the mismatch repair pathway maintain the fidelity of DNA replication. Here the authors show that tumors with concurrent loss of function of both pathways lead to mutation signatures that are not simply a sum of the signatures ...

Hydrogel‐Based 3D‐Printed Anthropomorphic Breast Phantom for Emulating Mechanical and Dielectric Properties of Mammary Tissue. Applications in Microwave Imaging

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printable breast phantom is developed using patient‐derived MRI data and hydrogels that replicate the dielectric properties of healthy and cancerous tissues. Mechanical and dielectric characterization confirm its suitability for microwave imaging.

The effect of educational mismatch on wages for 25 countries [PDF]

open access: yes
By making use of the Duncan&Hoffman model, the paper estimates returns to educational mismatch using comparable microdata for 25 European countries. Our aim is to investigate the extent to which the main empirical regularities produced by other papers on

Designing Vanadium‐Based Oxide Electrocatalysts for Water Splitting: Experimental and Mechanistic Insights with Machine Learning

open access: yesAdvanced Functional Materials, EarlyView.
This review establishes structure‐property‐mechanism relationships across six modification strategies for V‐based oxide water‐splitting electrocatalysts: lattice engineering, heteroatom doping, interface engineering, carbon‐based hybridization, morphology engineering, and surface reconstruction and pre‐catalyst design, where dissolution is reframed as ...

Optimal spatial arrangement of modules for large‐scale photovoltaic farms in complex topography

open access: yesIET Renewable Power Generation
The existing methods for determining the module arrangement in photovoltaic (PV) farms are considered insufficient as they are generally limited to the environment of flat ground without considering both physical and electrical factors.

Rapid Microwave Plasma Engineering of HfO2/C@C Core‐Shell Fibrous Membrane Toward Flexible High‐Performance Electromagnetic Wave Absorption

open access: yesAdvanced Functional Materials, EarlyView.
Rapid microwave plasma torch engineering tunes crystal phases, carbon graphitization and oxygen‐vacancy defects in HfO2/C@C core‐shell fibrous membranes. Synergistic multi‐loss effects optimize impedance matching to deliver −65.75 dB reflection loss and a 7.37 GHz effective bandwidth for flexible electromagnetic wave absorption.

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...
