Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

open access: yesEcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

Putting System Co‐Design at the Center of Chemo‐Biohybrid CO2 Valorization From Lab to Industrial Scale

open access: yesEcoEnergy, EarlyView.
Chemo‐biohybrid systems promise much, but single‐discipline research still limits progress. This perspective draws on thermocatalytic, electrocatalytic, and photocatalytic hybrid systems to highlight the need for system‐level co‐design and outline future directions.

Operational and environmental barriers to centralized composting in two small Brazilian municipalities: A longitudinal study

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Municipal solid waste management in small cities faces severe logistical and financial barriers regarding organic fraction treatment. This study evaluates biological selective collection in two small Brazilian municipalities (Astorga and Sabáudia), comparing dynamics between gated communities (GC) and public thoroughfares (PT) over an annual ...

Comparative Analysis of Al2O3/Water–TiO2/Chlorophyll Hybrid Nanofluids in a Photovoltaic–Thermal Solar Water Heating System

open access: yesEnergy Science &Engineering, EarlyView.
TiO2/chlorophyll bio‐hybrid nanofluid achieved the highest PVT performance, increasing thermal efficiency to 38.74% and overall efficiency to 51.35%, compared with 35.96% and 48.45% for Al2O3/water and 27.77% and 40.18% for water. The results demonstrate the potential of bio‐hybrid nanofluids for high‐efficiency solar thermal energy conversion ...

Ambiguity‐Aware Receding‐Horizon Optimization of Wind‐Hybrid Energy Storage Systems Using Type‐3 Fuzzy Modeling for Multimarket Participation

open access: yesEnergy Science &Engineering, EarlyView.
A Type‐3 fuzzy ambiguity encoder converts rolling wind, price, reserve‐activation, and confidence features into central estimates and nested uncertainty bounds. These parameters are updated within a receding‐horizon MILP/MIQP that coordinates wind, battery, and supercapacitor capacity across day‐ahead and ancillary‐service markets.

Electrolyzer Sizing and Techno‐Economic Assessment of Small‐Hydropower‐Based Green Hydrogen Using 3 Years of Hourly Generation Data

open access: yesEnergy Science &Engineering, EarlyView.
Three years (26,280 h) of measured Miryang Dam hydropower data were used to screen 300–1200 kW PEM electrolyzer capacities. A 600 kW unit provided the equal‐weight technical balance between hydropower capture (84.71%) and electrolyzer utilization (86.25%), whereas the planned 1 MW design captured 98.11% of available renewable energy but operated at a ...

Autonomous Nanomedicine: Closing the Biological Validation Gap

open access: yesExploration, EarlyView.
Delivery of nanoparticles to tumors has not improved in over fifteen years, and biological testing remains slow and separate from formulation design. This review proposes adding a Biology step to the design cycle, using organ chips and patient‐derived organoids, and assesses the readiness of each required technology.

Designing a Culture‐Driven C‐STEAM Project Framework for Vocational Education

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT Amid rapid technological advances and a growing emphasis on cultural sustainability in education, STEAM education has been widely adopted to support interdisciplinary learning and decision‐making skills. However, many STEAM implementations remain largely instrumental, regularly neglecting cultural meaning‐making, value orientation, and ...

Bayesian Multivariate Two‐Stage Volatility‐Return Models (MTS‐VR)

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This paper develops a class of models to capture the joint dynamics of asset returns and multivariate volatility. Owing to its two‐stage construction, this class is referred to as the multivariate two‐stage volatility‐return (MTS‐VR) model.
