Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗733 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Harmonization of biogas, greenhouse gases, water quality, and energy consumption in sidestream systems using computational assessment ↗
ABSTRACT Graphical summary of the study. Four anaerobic digestion configurations - conventional anaerobic digestion, thermal hydrolysis combined with conventional digestion, an anaerobic membrane bioreactor configuration, and the fully integrated configuration - are evaluated by plant-wide simulation across food-waste mixing ratios. Four indicators (specific methane production, sidestream load to mainstream, greenhouse gas emissions and energy footprint) are normalised and combined into a single composite Sustainability WWTP Index. This study evaluated the sustainability of four anaerobic dige…

Damage Detection in FGM Plates Using Modal Strain Energy and Gaussian Process Regression ↗
The extensive use of composite materials, particularly Functionally Graded Materials (FGMs), across a wide range of industrial applications has generated a critical demand for robust and reliable structural health monitoring (SHM) and damage detection systems to ensure operational safety and long-term structural integrity. In this paper, a numerically validated comprehensive SHM framework is proposed for FGM plates through finite element investigations, based on modal strain energy analysis and employing isogeometric analysis (IGA) for accurate dynamic response evaluation. The proposed damage…

Multi-Modal Bearing Fault Diagnosis Based on Multiscale Feature Enhancement and Adaptive Fusion ↗
Bearings are critical components of modern large-scale rotating machinery, such as wind turbines, and their operating condition directly affects system safety, reliability, and operation and maintenance costs. Vibration and current signals reflect the mechanical responses and electromechanically coupled responses induced by bearing faults, respectively, and the two modalities differ in their characteristic representations of fault information. When vibration and current features are fused only once at the end of a network, early complementary information cannot be incorporated into subsequent…

From Proxy to Impact: Evidence Translation in Functional Photovoltaic Cover Glass Coatings ↗
Functional coatings for photovoltaic (PV) cover glass are often supported by optical, photocatalytic, wettability, or dust removal measurements, but these endpoints do not by themselves establish PV performance, field persistence, maintenance reduction, or environmental benefit. This critical conceptual review uses a structured, non-comprehensive evidence map of 56 primary studies published from 2006 to 2026 (46 PV-targeted and 10 boundary cases; 24 Si-Ti-containing studies) to examine how evidence moves from coating characterization to system-level outcomes. Optical and surface-functional evi…

Risk-Aware Integration of Photovoltaics and Battery Storage into Human–Cobot Manufacturing: A Digital-Twin-Ready Co-Optimization Model for Sustainable Industrial Transition ↗
The increasing penetration of variable renewable energy requires industrial facilities to manage energy supply, production flexibility, and cost exposure simultaneously. This study develops a risk-aware model for the co-optimization of human–cobot production scheduling, on-site photovoltaic generation, and battery energy storage within a digital-twin-ready decision environment. The artifact is an offline prescriptive model; it is not connected to a physical production system and does not include automatic or real-time data exchange. A two-stage computational experiment was conducted using mixe…

Artificial intelligence driven lithium-ion battery recycling: from materials recovery to intelligent circular energy systems ↗
The rapid expansion of lithium-ion batteries (LIBs) in electric vehicles, portable electronics, and large-scale energy-storage systems has intensified concerns regarding critical material depletion, environmental impacts, and end-of-life battery management. Although conventional recycling technologies, including pyrometallurgical, hydrometallurgical, and direct recycling approaches, have enabled valuable resource recovery, their broader implementation remains challenged by heterogeneous battery chemistries and complex degradation. Artificial intelligence (AI) has emerged as a powerful tool to…

Integrated design and reliability enhancement technology of quantum current sensor for non-invasive measurement in power grid ↗
Non-invasive, high-precision current measurement is essential for smart grid perception, yet conventional clamp-on current transformers suffer from reduced accuracy under low-load conditions, battery dependence, and maintenance constraints. To address these challenges, this study proposes an NV-compatible solid-state quantum current sensing framework based on spin-resonance magnetic-field transduction, designed for integrated deployment and stable operation in practical grid environments. A non-invasive clamp structure converts line current into measurable magnetic signals, while a self-powere…

MAFNetMPI: A multimodal attention fusion network for machining process identification in 3D CAD models ↗
Abstract Machining process identification (MPI) is a critical step in automated manufacturability assessment and computer-aided process planning, enabling early decisions on feasible process chains directly from part geometry. Existing learning-based approaches to manufacturing-oriented shape analysis rely predominantly on a single geometric representation, such as voxels, point clouds, or multiview projections, each of which captures only a subset of the geometric cues relevant to machining. Furthermore, publicly available CAD datasets are primarily used for manufacturability analysis or feat…

Pilot-scale investigation of a convective fixed-bed reactor for CaO/Ca(OH)2 thermochemical energy storage ↗
The CaO/Ca(OH) 2 system is considered as one of the most promising thermochemical energy storage systems due to its high energy storage density and low material cost. However, existing studies are mainly limited to numerical simulations or laboratory-scale reactors, while pilot-scale investigations remain scarce. In addition, the high decomposition temperature of Ca(OH) 2 aggravates material sintering and limits the utilization of low- and medium-temperature heat sources. In this study, a pilot-scale convective fixed-bed reactor capable of loading 334.14 kg of CaO is proposed. During the heat…

A multifunctional anti-reflection coating on coverglass for III-V solar cells for space applications ↗
Solar photovoltaic (PV) cells are used to power satellites in space, and incorporate ultra-thin (∼150 μm), radiation-tolerant coverglass sheets to provide protection and mechanical support. Optical coatings can be applied to this coverglass surface, such as anti-reflection coatings to reduce reflection losses, typically a single layer of MgF 2 , which has limitations such as poor durability and lack of thermal management. Optical coatings can also contribute to passive cooling, reducing cell operating temperatures in the space environment where large temperature swings are present. This work d…

How to assess evidence about Energy
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
