Analysis and control of drilling riser dynamics in dual gradient drilling

open access: yes, 2013
The aim of this thesis is to investigate a dual gradient riser system, adapted for operations in the Gulf of Mexico and subjected to first- and second-order wave forces, current and rig/vessel motion.Deep water drilling in narrow pressure zones pose several challenges for handling well pressure.

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis

open access: yesAdvanced Science, EarlyView.
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

Green and Low‐Carbon Synthesis of Lithium Sulfide (Li2S): From Fundamental Mechanisms to Scalable Manufacturing for Next‐Generation Energy Storage

open access: yesAdvanced Science, EarlyView.
This review focuses on green synthesis routes for lithium sulfide (Li2S)—a key material for lithium–sulfur batteries and sulfide solid electrolytes, whose traditional carbothermal reduction remains energy‐intensive and unsustainable. Specifically examined routes include low‐temperature solid‐state reactions, magnesiothermal reduction, and solution ...

Atomically Correlated Phosphorus–Sulfur Sites in Carbon Nitride for Efficient Hydrogen Peroxide Production

open access: yesAdvanced Science, EarlyView.
Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

open access: yesAdvanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...
