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 ↗646 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.

Experimental assessment of SWCNT-added waste cooking oil biodiesel–diesel blend in a single-cylinder diesel generator: performance, emissions, energy, exergy, sustainability, and exergoeconomic analyses ↗
In this study, the effects of adding 50 and 100 ppm of single-walled carbon nanotubes (SWCNTs) to D85B15 fuel, prepared from biodiesel derived from waste cooking oil, on the performance, exhaust emissions, energy, exergy, sustainability, and exergoeconomic indicators of a single-cylinder diesel engine-generator system were experimentally investigated. D100, B100, D85B15, D85B15S50, and D85B15S100 fuels were tested at a constant engine speed of 3000 rpm and in the range of 1000–5000 W active electrical output power. The reported power values correspond to the active electrical output measured a…

Reprogramming energy system for growth and bioproduction from CO₂ and methanol in Escherichia coli ↗
Microbial CO₂ assimilation provides a strategy for sustainable biomanufacturing. However, CO₂ reduction requires substantial energy input, while native energy systems are tightly regulated and extensively consumed by endogenous metabolism, limiting assimilation efficiency. Here, we design and construct an orthogonal energy system in Escherichia coli, achieving an intracellular NUDH concentration exceeding 7.0 mM and an NUDH/NUD⁺ ratio above 55. Subsequently, we design a CO₂-formate-acetyl-CoA-pyruvate-malate pathway and reprogram key enzymes for NUDH-dependent operation. Integration of the OES…

Unexpected functional role of the transactivation domain for nuclear import of STAT5 ↗
Abstract Signal transducer and activator of transcription 5 (STAT5) is a key transcriptional regulator acting downstream of hematopoietic cytokines and hormones, such as erythropoietin (Epo), thrombopoietin or prolactin. STAT5-mediated gene regulation involves tyrosine phosphorylation at cytokine receptors and subsequent nuclear import. We studied STAT5 nucleocytoplasmic shuttling via live-cell imaging of fluorescent mutants in STAT5 -/- HeLa EpoR cells. Unexpectedly, STAT5 mutants lacking the transactivation domain (TAD) were retained in the cytoplasm following Epo stimulation. Building upon…

Interface Engineering Toward High‐Efficiency CIAS Thin‐Film Solar Cells Using a Cadmium‐Free CuAlSe 2 Buffer Layer: A SCAPS‐1D Investigation ↗
Cu(In,Al)Se 2 (CIAS)‐based thin‐film solar cells remain largely unexplored regarding buffer layer and interface engineering. This work reports a SCAPS‐1D investigation of CuAlSe 2 (CASe) as a cadmium‐free alternative to CdS, starting from a validated Glass/Mo/CIAS/CdS/ZnO/ITO/(Ni/Al)/MgF 2 model reproducing experimental results. Replacing CdS with CASe maintains constant short‐circuit current density while improving band alignment at the buffer/absorber interface, reducing interfacial recombination and raising open‐circuit voltage ( V OC ), without additional parasitic absorption losses. A par…

Multimodal Fusion‐Based POI Recommendation With Consumer Equilibrium Guidance ↗
ABSTRACT Point of interest (POI) recommendation services have gained widespread adoption in various consumer fields. However, existing POI recommendation methods often neglect the intrinsic logic of consumer behaviors and multimodal data fusion analysis. To fill this research gap, this paper proposes a multimodal fusion‐Based POI recommendation method with consumer equilibrium guidance. This method considers different data modalities such as graphs, time series, images, text, and so forth, and draws inspiration from consumer equilibrium and diminishing marginal utility theories to simulate the…

Identification and ranking on thermal hydraulic phenomena in integrated SMR during station blackout ↗
The Phenomena Identification and Ranking Table (PIRT), as a systematic tool in nuclear safety analysis, is widely used to identify key physical phenomena in accident scenarios and assess their importance and level of knowledge. Although the traditional PIRT method has the advantage of structured analysis, its strong reliance on experts' subjective judgments affects the objectivity and repeatability of ranking process. This study mainly focuses on thermal-hydraulic (T-H) phenomena occurring in a typical small modular pressurized water reactor (SMPWR) during station blackout (SBO) accident, and…

Fully solution-processed AgBiS2 thin film solar cells with carbon electrodes via stoichiometry-mediated crystal growth ↗
AgBiS 2 thin-film solar cells have emerged as promising photovoltaic materials owing to their non-toxic composition, ideal bandgap, and high absorption coefficient. However, state-of-the-art devices typically rely on evaporated Au or Ag back electrodes, which requires high-vacuum deposition processing and raise manufacturing cost. Here, we introduce a low-temperature, solution-processed carbon paste as a vacuum-free back-contact electrode for AgBiS 2 solar cells. To simultaneously overcome the poor crystallinity of AgBiS 2 thin-film, we systematically tune the Ag/Bi ratio in the molecular prec…

S2DFusion: a statistical and scale difference attention network for infrared and visible image fusion ↗
Infrared and visible image fusion aims to integrate cross-modal complementary information for comprehensive all-weather scene perception. However, existing methods often fail to effectively decouple background noise from modality-specific salient features, leading to contrast degradation, diminished thermal target prominence, and the loss of fine texture details in the fused images. To address these limitations, we propose S2DFusion, a novel statistical and scale-differential attention network that constructs a “difference-oriented” explicit decoupling and fusion paradigm. Specifically, the in…

Introducing citizen energy resilience: Evidence from Finland ↗
This study examines citizen energy resilience (CER) as a sociotechnical construct. Responding to increasing disruptions driven by climate change, market volatility and geopolitical instability, this research conceptualizes CER as emerging from the dynamic interplay of technical systems, governance structures, and citizens' uneven capacities to anticipate, cope with, and recover from energy-related disruptions. Drawing on empirical evidence from Finland, the study analyzes a large corpus of national news media alongside interviews with civil society organizations, municipalities, and energy-sec…

Uncertainty-aware reconstruction of full process maps in laser-directed energy deposition using scarce data ↗
Abstract Accurate representation of bead geometry is essential for establishing reliable process-geometry relationships in laser-directed energy deposition (L-DED). In contrast to existing approaches that focus on constructing complete process maps within a single manufacturing process, this work leverages experimentally derived scalar bead descriptors (width, height, and area) from a source process to enable data-efficient reconstruction of process maps for a different target manufacturing process. To achieve this, a neural network-based data-driven modeling approach is proposed, leveraging k…

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.
