Parametric LCA model for power electronic ecodesign process: Addressing MOSFET‐Si and HEMT‐GaN technological issues
Authors: Fang Li , Rosset Yannis , Sarrazin Benoît , Lefranc Pierre , Rio Maud 
Published: January 2025

AbstractTraditional efforts of the last decades to optimize energy efficiency during the use phase of power electronic (PE) appear insufficient for achieving environmental sustainability. These single‐criterion optimization approaches often lead to unintended negative environmental impacts, such as air, water, and soil pollutions, or additional raw material flow extraction to develop new technologies. Design options easing repair, reuse, and recycling of PE products are usually reduced with higher power density technology choices. Life cycle assessment (LCA) offers a framework for evaluating these impacts, but the conventional LCA is primarily for post‐design evaluation, and is resource‐ and time‐intensive. To make LCA a proactive design method that allows teams to monitor environmental consequences from the beginning of design planning, this study developed a parametric life cycle assessment (PLCA) meta‐model specifically for PE, integrated into an innovative ecodesign process. The PLCA meta‐model identifies key parameters influencing environmental impacts across the product life cycle and establishes mathematical relationships between these control parameters and environmental impact indicators. The case study results shows that the integration of this new PLCA model in the beginning of the design process has supported PE designers to develop, evaluate, and optimize ecodesign PE product circular life cycle scenarios.

AbstractAcute pancreatitis (AP) is a severe inflammatory condition of the pancreas with significant morbidity and mortality, particularly in its necrotizing form. This review explores the management of peripancreatic collections and in particular necrotizing pancreatitis, focusing on the evolution from traditional open surgical methods to contemporary minimally invasive image-guided techniques. AP can lead to various local complications, including pancreatic pseudocysts, acute necrotic collections, and walled-off necrosis. Imaging plays a crucial role in diagnosing complications of AP, while treatment approaches have shifted toward a step-up strategy involving percutaneous, endoscopic, and minimally invasive methods. Percutaneous necrosectomy, combining mechanical and chemical debridement, has shown promising results. Mechanical necrosectomy uses devices like baskets and retrieval nets, while chemical necrosectomy adds agents like hydrogen peroxide and streptokinase. Current evidence suggests that the step-up approach, starting with percutaneous drainage or necrosectomy and escalating to endoscopic or surgical interventions, if necessary, improves patient outcomes. The review underscores the need for a multidisciplinary approach in managing complicated AP and highlights ongoing advancements in minimally invasive techniques.
Performance of vortex pump in CFD simulations with rough walls
Authors: Li Wenguang 
Published: January 2025

Flow passages in vortex pumps usually have rough walls. Precise consideration of wall roughness is an important issue in pump flow simulations. Numerical studies of the effects of wall roughness on the performance of vortex pumps are quite rare, especially with different interface models. Turbulent flows of water in a vortex pump with a specific speed of 76 are simulated using 1/8 and whole impeller fluid domains with rough walls, using the three-dimensional Reynolds-averaged Navier–Stokes equations, the standard k-ɛ model, and a scalable wall function in Ansys CFX 2019 R2. Equivalent sand grain roughnesses ks = 0.586 and 9.38 μm are determined for the chamber casing, volute, and suction pipe, and ks = 18.47 and 36.94 μm for the impeller by using the arithmetic average roughness Ra of the materials used in the pump and the correlation between ks and Ra given in the literature. The mixing loss along the interface between impeller and volute in the transient rotor model is determined. The rates of change of the head, shaft-power, and efficiency of the pump due to wall roughness are calculated. The transient rotor model with whole impeller domain and the frozen rotor model with 1/8 impeller domain for rough walls with Ra = 0.1 μm in the suction pipe, volute, and chamber and 3.2 μm in the impeller give the most accurate predictions of pump performance compared with experimental data. The transient rotor model with whole impeller domain gives more accurate predictions of pump performance than the frozen rotor model with 1/8 impeller domain. The mixing loss rises quickly at high flow rates. The transient rotor model with whole impeller domain gives plausible predictions of the rates of change.

Resumen
En español, el complemento directo dislocado (e.g., A él lo atropellaron) forma
parte de las construcciones que tematizan un participante distinto del agente. En este sentido, son construcciones que expresan el
contenido proposicional desde una perspectiva pasiva. Sin embargo, a diferencia de la pasiva con ‘ser’, el complemento directo
dislocado no ha sido objeto de estudios empíricos destinados a repertoriar su combinatoria con distintos tipos de verbos. El
presente estudio explora los usos y frecuencias del complemento directo dislocado con referente humano y agente no explícito
(e.g., A ella la premiaron). Un total de 164 construcciones del corpus CORPES XXI fueron analizadas atendiendo a
las siguientes variables: contexto (violento vs. neutro), grado de afectación (con contacto vs. sin contacto), tipo de cambio
experimentado (estado o propiedad / ubicación / psicológico / benéfico). Los resultados indican que esta construcción es
significativamente productiva en contextos violentos y combinada con verbos de contacto físico para marcar cambios de estado o
relativos a una propiedad del argumento afectado. Estos resultados ponen en evidencia la prominencia de esta construcción en
español para expresar la afectación física y violenta con verbos de valencia psicológica negativa en predicados regidos por el
primitivo semántico [CAUSE].
Revisiting the reported speech as a mitigation device in the PRESEEA-Seville oral corpus
Authors: Repede Doina 
Published: January 2025

Abstract
This article aims to describe the use of mitigating reported speech concerning three general mitigation functions
— self-protection, prevention, and repair — identified in the works of Albelda et al. (2014, 2021). This goal will be achieved through a review of relevant
literature on this phenomenon and an analysis of 72 semi-structured interviews taken from the PRESEEA-Seville oral corpus. From a
sociolinguistic perspective, we will also examine how the employ of mitigating reported speech functions is affected by three
fundamental social criteria: gender, age, and level of education. Additionally, we will provide information on how frequently they
are used. Generally, we observe a prevalence of the self-protection function, especially in the use of direct quotations. This
helps to preserve the speaker’s face, resulting in a positive impact. In terms of social factors, this function is notable in both
male and female participants with low levels of education, particularly among first-generation individuals.

Published: January 2025

Abstract
The majority of existing mechanical devices are only capable of measuring a single parameter. They are constructed primarily from metal processing, resulting in a substantial weight, elevated manufacturing costs, and a fixed and inflexible accuracy and assembly methodology. Accordingly, this paper presents the design of a lightweight RV reducer test platform, which enhances the flexibility of high-precision measurement. The test platform employs topology optimization lightweight structure design and 3D printing technology. Static simulation is used to lightweight the structure and add an adjustable structure. It significantly reduces cost and weight while having an adjustable self-connection structure and a wide range of application scenarios. It improves the flexibility of high-precision measurement while ensuring sufficient strength. In order to verify the measurement performance of the platform, the wavelet threshold method with excellent denoising effect was used to analyze the acceleration power spectral density of each part of the test platform at different rotation speeds. The results show that the wavelet threshold method could effectively filter noise and extract key experimental data. The accelerometer results show that the test bench has superior stability at both 0.5 r min−1 and 120 r min−1 speeds, and has practical application value. The simulation also verifies that the test platform has sufficient rigidity to meet the working conditions.

Published: January 2025

Abstract
In this work, a PEDOT:PSS/Sn:α-Ga2O3 hybrid heterojunction diode (HJD) photodetector was fabricated by spin-coating highly conductive PEDOT:PSS aqueous solution on the mist chemical vapor deposition (Mist-CVD) grown Sn:α-Ga2O3 film. This approach provides a facile and low-cost p-PEDOT:PSS/n-Sn:α-Ga2O3 spin-coating method that facilitates self-powering performance through p−n junction formation. A typical type-Ⅰ heterojunction is formed at the interface of Sn:α-Ga2O3 film and PEDOT:PSS, and contributes to a significant photovoltaic effect with an open-circuit voltage (V
oc) of 0.4 V under the 254 nm ultraviolet (UV) light. When operating in self-powered mode, the HJD exhibits excellent photo-response performance including an outstanding photo-current of 10.9 nA, a rapid rise/decay time of 0.38/0.28 s, and a large on/off ratio of 91.2. Additionally, the HJD also possesses excellent photo-detection performance with a high responsivity of 5.61 mA/W and a good detectivity of 1.15 × 1011 Jones at 0 V bias under 254 nm UV light illumination. Overall, this work may explore the potential range of self-powered and high-performance UV photodetectors.

Published: January 2025

Abstract
Frequency combs with equally spaced frequency lines show great potentials for applications in spectroscopy, imaging, communications, and so on. In the terahertz frequency region, the quantum cascade laser (QCL) is an ideal radiation source for frequency comb and dual-comb operation. The systematic evaluation of phase noise characteristics of terahertz QCL frequency comb and dual-comb sources is of great importance for high precision measurements. In this work, we present detailed measurements and analysis of the phase noise characteristics of terahertz QCL frequency comb and dual-comb sources emitting around 4.2 THz with repetition frequencies of ~6.2 GHz. The measurement results for the current noise of the direct current (DC) sources (that are used to electrically pump the terahertz QCLs) indicate that at 100 Hz, the current noise for DC-1 and DC-2 is 0.3895 and 0.0982 nA/Hz1/2, respectively. Such levels of current noise can be safely disregarded. The phase noise of radio frequency (RF) generators (that are employed for injection locking and phase locking), intermode beatnotes, and dual-comb signals with and without phase-locked loop (PLL) are all measured and compared. The experimental results show that in the free-running mode, the phase noise of the intermode beatnote signals is always lower than that of the dual-comb signals across all frequencies. Additionally, the phase noise induced by the RF generators is negligible. By employing the phase locking technique, the phase noise of the intermode beatnote and dual-comb signals in the low offset frequency band can be significantly suppressed. At an offset frequency of 100 Hz, the measured phase noise values of the dual-comb line without and with phase locking are 15.026 and −64.801 dBc/Hz, respectively.
Laser processing induced nonvolatile memory in chaotic graphene oxide films for flexible reservoir computing applications
Authors: Chen Bo , Zhu Baojie , Wu Yifan , Sang Pengpeng , Wu Jixuan , Zhan Xuepeng , Chen Jiezhi 
Published: January 2025

Abstract
Graphene oxide, as a 2D material with nanometer thickness, offers ultra-high mobility, chaotic properties, and low cost. These make graphene oxide memristors beneficial for reservoir computing (RC) networks. In this study, continuous-wave (CW) laser processing is used to reduce chaotic graphene oxide (CGO) films, resulting in the non-volatile storage capability based on the reduced chaotic graphene oxide (rCGO) films. Laser power significantly impacts the characteristics of the rCGO memristor. Material characterization indicates that laser radiation can effectively reduce the oxygen content in CGO films. With optimized laser power, the rCGO memristor achieves a large ratio at 18 mW laser power. Benefiting from the short-term memory characteristics, distinct conductive states are achieved, which are further utilized to construct RC networks. With a third control probe, the rCGO memristor can express rich reservoir states, demonstrating accuracy in predicting the Hénon map with an NRMSE below 0.3. These findings provide the potential for developing flexible RC networks based on graphene oxide memristors via laser processing.

Published: January 2025

Abstract
Owing to the unique characteristics of ultra-thin body and nanoscale sensitivity volume, MoS2-based field-effect transistors (FETs) are regarded as optimal components for radiation-hardened integrated circuits (ICs), which is exponentially growing demanded especially in the fields of space exploration and the nuclear industry. Many researches on MoS2-based radiation tolerance electronics focused on the total ionizing dose (TID) effect, while few works concerned the displacement damage (DD) effects, which is more challenging to measure and more crucial for practical applications. We first conducted measurements to assess the DD effects of MoS2 FETs, and then presented the stopping and ranges of ions in matter (SRIM) simulation to analysis the DD degradation mechanism in MoS2 electronics. The monolayer MoS2-based FETs exhibit DD radiation tolerance up to 1.56 × 1013 MeV/g, which is at least two order of magnitude than that in conventional radiation hardened ICs. The exceptional DD radiation tolerance will significantly enhance the deployment of MoS2 integrated circuits in environments characterized by high-energy solar and cosmic radiation exposure.

Numerical study of Darcy’s law of yield stress fluids on a deep tree-like network
Authors: Munier Stéphane , Rosso Alberto 
Published: January 2025

Abstract
Understanding the flow dynamics of yield stress fluids in porous media presents a substantial challenge. Both experiments and extensive numerical simulations frequently show a non-linear relationship between the flow rate and the pressure gradient, deviating from the traditional Darcy law. In this article, we consider a tree-like porous structure and utilize an exact mapping with the directed polymer with disordered bond energies on the Cayley tree. Specifically, we adapt an algorithm recently introduced by Brunet et al (2020 Europhys. Lett.
131 40002) to simulate exactly the tip region of branching random walks with the help of a spinal decomposition, to accurately compute the flow on extensive trees with several thousand generations. Our results confirm the asymptotic predictions proposed by Schimmenti et al (2023 Phys. Rev. E
108 L023102), tested therein only for moderate trees of about 20 generations.

Abstract
Tissue-engineered grafts that mimic articular cartilage show promise for treating cartilage injuries. However, engineering cartilage cell-based therapies to match zonal architecture and biochemical composition remains challenging. Decellularized articular cartilage extracellular matrix (dECM) has gained attention for its chondro-inductive properties, yet dECM-based bioinks have limitations in mechanical stability and printability. This study proposes a rapid light-based bioprinting method using a tyrosine-based crosslinking mechanism, which does not require chemical modifications of dECM and thereby preserves its structure and bioactivity. Combining this resin with Filamented Light (FLight) biofabrication enables the creation of cellular, porous, and anisotropic dECM scaffolds composed of aligned microfilaments. Specifically, we focus on the effects of various biopolymer compositions (i.e. hyaluronic acid, collagen I, and dECM) and inner architecture (i.e. bulk light vs FLight) on immune response and cell morphology, and we investigate their influence on nascent ECM production and long-term tissue maturation. Our findings highlight the importance of FLight scaffolds in directing collagen deposition resembling articular cartilage structure and promoting construct maturation, and they emphasize the superiority of biological-rich dECM over single-component materials for engineering articular cartilage, thereby offering new avenues for the development of effective cartilage tissue engineering strategies.

Authors: Ramay Shahid M , Aldosary Mohammed H 
Published: January 2025

Abstract
Supercapacitors are pivotal for the advancement of energy storage technologies, offering unparalleled power density and rapid charge–discharge cycles essential for modern electronic and automotive applications. Combining different materials is a powerful approach to enhancing the electrochemical properties of each constituent. In the current report, we examine the structural, morphological, and electrochemical characteristics of pure NiCo2O4 and NiCo2O4%-5% Ti3AlC2 composite. The pristine NiCo2O4 is fabricated utilizing the Sol–Gel auto-combustion route, while its composite NiCo2O4%-5% Ti3AlC2 is prepared in ethanol using the ultrasonic process. Structural analysis confirms the existence of the cubic spinel phase of NiCo2O4 with the Fd

m space group. Surface morphological analysis reveals a distribution of well-defined particles with a decrease in particle size from 50–40 nm. Elemental analysis confirms the purity of the sample by the presence of stoichiometric amounts of the elements. Electrochemical analysis of the studied composite exhibits superior electrochemical properties. Specifically, the highest specific capacitance of 129. 62 F g−1 for pure NiCo2O4 and 126.82 F g−1 for NiCo2O4-5% Ti3AlC2 composite is achieved at 2 mA g−1 current density. However, the addition of 5% Ti3AlC2 in NiCo2O4 improved its energy density by 27%. Additionally, NiCo2O4–5% Ti3AlC2 material demonstrated excellent capacitance retention, maintaining 87% after 8000 charge–discharge cycles. These findings show the potential of the studied composite for supercapacitor electrode materials for electrochemical energy storage.
