Dynamic Micro-Vibration Monitoring Based on Fractional Optical Vortex

Photonics
In this study, we propose a novel approach for dynamic micro-vibration measurement based on an interferometric system utilizing a fractional optical vortex (FOV) beam as the reference and a Gaussian beam as the measurement path.

Unveiling the Influence of Annealing Temperature on Properties of CZTSSe Nanocrystals

Advanced Physics Research, EarlyView.
This study investigates the synthesis and annealing temperature effects on CZTSSe nanopowders for photoelectrochemical water splitting. Using solution‐based methods, the research explores how temperatures from 100 to 350 °C influence morphology, structure, and optical properties. Findings reveal temperature‐dependent grain growth and structural changes,

Evaluation of multi‐user multiple‐input multiple‐output digital beamforming algorithms in B5G/6G low Earth orbit satellite systems

International Journal of Satellite Communications and Networking, EarlyView., 2023
In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

A Sophisticated Terahertz Photonic Crystal Fiber Sensor Design for Highly Accurate Detection of Kerosene Mixtures

Advanced Physics Research, EarlyView.
A novel Photonic Crystal Fiber sensor with an octagonal cladding and hollow core is developed to detect kerosene adulteration. At 2.2 THz, the sensor achieves 96.80% relative sensitivity, an effective mode loss of 0.00667 cm⁻¹, and minimal confinement loss (6.78 × 10⁻8 dB m−1).

GaAs Growth on Ge‐Buffered Discontinuous (111)‐Faceted V‐Groove Silicon Substrates

Advanced Physics Research, EarlyView.
This work demonstrates antiphase boundary (APB)‐free GaAs growth on Ge buffers formed on discontinuous (111) V‐groove Si substrates. By tailoring the Ge buffer morphology to form well‐defined facets, APB formation is suppressed. This approach offers alternative solutions to achieving APB‐free III–V integration on CMOS‐compatible on‐axis silicon without

Are Artificial Intelligence and Circular Economy Activities ‘Run‐of‐the‐Mill’ in Integrated Reporting?

Business Strategy and the Environment, EarlyView.
ABSTRACT This study aims to investigate the nexus of artificial intelligence (AI) and circular economy (CE) activities in integrated reporting (IR) practices. The study used data on the top 100 most sustainable corporations provided by Corporate Knights, which analyses roughly 7000 public firms with annual revenue of at least US$ $1 billion and the Dow

Evaluation of lightning‐induced overvoltage on a 10 kV distribution line based on electromagnetic return‐stroke model using finite‐difference time‐domain

High Voltage
Accurate simulation of lightning‐induced overvoltage for overhead distribution lines is helpful to prevent lightning trip accidents. An electromagnetic return‐stroke model was used to represent lightning and then a 3D finite‐difference time‐domain (FDTD)

Mechanical Stress‐Tolerant Diffusion‐Dependent Electrode With Well‐Dispersed Silicon Particles for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
We propose a mechanical stress‐tolerant all‐solid‐state electrode with morphologically controlled active materials. In this design, local stress induced by the concentrated volume expansion during lithiation is significantly reduced, ensuring conformal contact between solid components and resulting in stable capacity retention over repeated cycles ...

Straightforward Method to Orient Black Phosphorus from Bulk to Thin Layers using a Standard Green Laser

ChemNanoMat, EarlyView.
The angle resolved polarized Raman spectroscopy setup in the black phosphorus crystal frame. Polar plots of Ag1 and B2g modes reveal the material's orientation, which is compared with bulk and flake orientations from electron imaging and diffraction. This validates the orientation method using a simple single‐wavelength (514 nm) setup.

Internet of Things (IoT) and the Environmental Sustainability: A Literature Review and Recommendations for Future Research

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT As the Internet of Things (IoT) surges forward, intersecting with an urgent demand for environmental sustainability (ES), digital technologies emerge as potent orchestrators of systemic transformation. Employing a subtle blend of bibliometric‐systematic literature review (B‐SLR) and qualitative insights, this research investigates IoT's ...
