Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

open access: yesAdvanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Load demand fulfillment through GFM-inverter based modified droop-control under various network conditions

open access: yesEnergy Reports
This paper offers a systematic approach to understanding the performance of the grid-forming inverter in both isolated and hybrid configuration with a grid-following inverter in low-voltage distribution network. While most existing studies concentrate on

First air-tolerant effective stainless steel microbial anode obtained from a natural marine biofilm [PDF]

open access: yes, 2009
Microbial anodes were constructed with stainless steel electrodes under constant polarisation. The seawater medium was inoculated with a natural biofilm scraped from harbour equipment.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Grid-forming frequency shaping control

open access: yes, 2020
As power systems transit to a state of high renewable penetration, little or no presence of synchronous generators makes the prerequisite of well-regulated frequency for grid-following inverters unrealistic. Thus, there is a trend to resort to grid-forming inverters which set frequency directly. We propose a novel grid-forming frequency shaping control

Grid-following and grid-forming PV and wind turbines

open access: yes, 2021
As penetration of photovoltaic (PV) and wind generation systems driven by grid-connected power converters monotonously increases, unusual interactions between innovative and legacy generation systems become more concerning, since they threaten the system stability and reliability.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

open access: yesAdvanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Comparison Study of the Wideband Oscillation Risk of MMC between Grid-Following and Grid-Forming Control

open access: yesEnergies
Currently, research on the small-signal stability of grid-forming converters under two control modes, grid-following and grid-forming, mainly focuses on low-level converters.
