Understanding and Regulating C–N Coupling Pathways for Electrocatalytic Urea Synthesis From CO2 and NO3−/NO2−

open access: yesAdvanced Science, EarlyView.
Understanding and regulating C–N coupling is central to electrocatalytic urea synthesis from CO2 and NO3−/NO2−. This review outlines representative coupling pathways, summarizes carbon‐ and nitrogen‐side intermediate regulation strategies, and highlights in situ/operando tools for mechanistic clarification and catalyst design. ABSTRACT Electrocatalytic

Trophic history of French sub-alpine lakes over the last ~150 years: phosphorus reconstruction and assessment of taphonomic biases

open access: yesJournal of Limnology, 2013
Like many lakes worldwide, French sub-alpine lakes (lakes Annecy, Bourget and Geneva) have suffered from eutrophication in the mid-20th century. Although restoration measures have been undertaken and resulted in significant reductions in nutrient inputs ...

Exploring Quantum Support Vector Regression for Predicting Hydrogen Storage Capacity of Nanoporous Materials

open access: yesAdvanced Intelligent Discovery, EarlyView.
In this study we employed support vector regressor and quantum support vector regressor to predict the hydrogen storage capacity of metal–organic frameworks using structural and physicochemical descriptors. This study presents a comparative analysis of classical support vector regression (SVR) and quantum support vector regression (QSVR) in predicting ...

Species Dynamics and Gene Expression in Algal Polycultures Under Mixotrophic Cultivation in Outdoor Pilot‐Scale Nordic Conditions

open access: yesBiotechnology and Bioengineering, EarlyView.
These results demonstrate that mixotrophic conditions drive both microbial community shifts and metabolic reprogramming, underscoring the importance of cultivation strategy and polyculture selection for targeted applications such as nutrient recovery and bioproduct generation.

The use of diatom records to establish reference conditions for UK lakes subject to eutrophication [PDF]

open access: yes, 2011
A knowledge of pre-disturbance conditions is important for setting realistic restoration targets for lakes. For European waters this is now a requirement of the European Council Water Framework Directive where ecological status must be assessed based on ...

Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

open access: yesCarbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.
