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 ↗690 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.

Energy-efficient dynamic temperature control for frozen plant-based food transport using model predictive control ↗
Abstract Refrigerated road transport is energy intensive because conventional controllers regulate compartment air temperature reactively while the cargo itself changes temperature slowly. In this work, the potential energy savings from shifting the control reference from air to cargo core temperature are studied using a simulation model of a semi-trailer carrying frozen plant-based food. The controller uses a two-node thermal model to track both the fast air dynamics and the slow cargo thermal response, and a compressor efficiency map to time cooling decisions for periods of higher coefficien…

Impact of climate change on the photovoltaic power potential in Sweden across 21st century ↗
Abstract Solar photovoltaic generation strongly relies on weather conditions, which will be affected by future climate change. Traditional methods for estimating photovoltaic generation potential often overlook detailed installation factors and snow impacts, leading to inaccuracies in high-latitude areas. We assess future photovoltaic system performance in Sweden using a validated photovoltaic installation model that incorporates air temperature, radiation and snow conditions. Applying this model to four Swedish cities under low- and high-emission climate change scenarios and three climate sim…

Dark-State-Mediated Low-Energy Electron Attachment to Molecular Oxygen: Symmetry Adapted Decomposition of the DEA Resonance through Dyson-Orbitals’ Incoherent Mixing ↗
Abstract Dissociative electron attachment (DEA) to O2 exhibits a prominent resonance peak at ∼6.5 eV, producing O– with a single kinetic energy band (∼1.5 eV) and a distinct four-lobed angular distribution. Using velocity-map imaging and complex absorbing potential equation-of-motion electron-attachment coupled-cluster singles and doubles (CAP-EOM-EA-CCSD) calculations, we notice that this resonance is mediated by electron-impact excitation to the optically dark a1Δg and b1Σg+ states, which suggests electron impact excitation to these optically dark excited states provides an appropriate elect…

In Situ Supramolecular Depolymerization Enables Bifunctional Buried‐Interface Passivation in Inverted Perovskite Solar Cells ↗
ABSTRACT Introducing multidentate organic passivators has emerged as an effective strategy for defect passivation at the buried interface of inverted perovskite solar cells (PSCs). However, the active polar functional groups within these passivators are prone to supramolecular polymerization, which compromises passivation effectiveness. Herein, a supramolecular depolymerization strategy synergistically driven by thermal annealing and heteromolecular interactions is proposed. This approach enables the in situ depolymerization of the Zaltoprofen (Za) supramolecular structures introduced at the b…

CFD investigation of a novel gabion-based porous medium configuration for energy dissipation in ogee spillway stilling basins ↗
Ogee spillways which provide very large discharge rates are extensively employed for civil engineering applications, but high velocity flows generated by Ogee spillways can be seriously harmful to downstream structures. This numerical investigation is conducted to assess the potential of adding porous media (uniform gabions and cross shaped gabions, with varying porosities: 30%, 40% and 50%) to the stilling basin at the bottom of ogee spillways to dissipate energy. The maximum improvement in relative energy dissipation compared with the smooth-bed configuration reached approximately 65% for th…

Data-driven control for orbit transition of piezoelectric energy harvesters under stochastic excitation ↗
To address the tendency of bistable piezoelectric energy harvesting systems to remain trapped in low-energy intrawell oscillations and the difficulty of sustaining high-energy interwell motion under stochastic disturbances, this study proposes a data-driven event-triggered jump–drift hybrid control method. The proposed method takes the neighborhood of a high-energy reference orbit as the control target and constructs a complete electromechanical state representation using displacement, velocity, and piezoelectric voltage. A signed orbit error is further defined through local radial projection…

Tool-grounded large language models for decision-level fusion in fault diagnosis ↗
Modern condition-monitoring systems generate heterogeneous information, such as high-rate sensor streams, derived health indicators, and discrete event histories, that must be combined into actionable diagnostic statements. Large language models (LLMs) are attractive as a decision-level fusion mechanism because they natively handle the textual modality, but their use in safety-critical fault diagnosis is impeded by hallucinated numerical content and stochastic outputs. This paper proposes a two-level information-fusion framework that uses an LLM as a constrained fusion operator rather than as…

Peer to multi peer energy trading for renewable communities using blockchain smart contracts and social welfare allocation ↗
H 2 refuelling corridors plus EV mobility services require joint handling of station scheduling, price-sensitive mobility response, multi-carrier dispatch, plus carbon-accounting rules. Prior studies have improved H 2 -station planning, carbon-aware scheduling, plus incentive pricing; however, verified settlement, welfare allocation, plus mobility-carrier coupling often remain compartmentalized. This paper develops a Stackelberg coordination framework for a carbon-constrained multi-carrier hub covering EVs plus HFCVs. IESO acts as upper-level coordinator, whereas ES, LA, plus VA adjust supply,…

Self-regenerating photocatalytic water treatment systems: integrating cognitive AI control, bio-inspired self-healing, and thermoelectric energy harvesting ↗
Conventional photocatalytic water treatment systems face persistent limitations in terms of catalyst deactivation, energy consumption, and adaptability to variable influent quality. This review examines the integration of three emerging technological domains, machine learning driven process optimization, bio-inspired self-healing material strategies, and thermoelectric energy recovery, as a framework for developing more autonomous and resource-efficient photocatalytic treatment systems. A systematic literature search was conducted in Web of Science, Scopus, IEEE Xplore, and PubMed (January 200…

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.
