Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

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

EcoEnergy, 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

Oxygen Vacancy‐Engineered S‐Scheme FeOOH/Ov‐BiVO4 Heterojunction: Interfacial Charge Dynamics Optimization and Pathogenic Polypeptide Aggregates Degradation

EcoEnergy, EarlyView.
By integrating interfacial oxygen vacancies and cone‐shaped FeOOH, a highly efficient S‐scheme FeOOH/Ov‐BiVO4 photoanode was constructed. This dual‐strategy significantly accelerates charge transfer and enhances reactant adsorption, achieving outstanding photoelectrochemical degradation of pathogenic amyloid β‐polypeptide aggregates.

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.

An Excellent Deep‐Ultraviolet Nonlinear Optical Crystal Realized via a Functional Group Based on a Two‐in‐One Strategy

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A “two‐in‐one” design strategy integrating guanidinium and carboxyl functional groups was developed to overcome the intrinsic trade‐off among SHG response, ultraviolet cutoff edge, and birefringence in DUV NLO crystals. Benefiting from non‐π‐conjugated electronic isolation, Zn‐GPA(II) simultaneously achieves a strong SHG response (2.1 × KH2PO4), an ...

Soluble Nanomedicine Against Soluble Neurosensitizers to Effectively Relieve Osteoarthritis Pain and Joint Damage

Exploration, EarlyView.
Osteoarthritis pain arises not only from joint damage but also from inflammation, abnormal bone changes, and excessive nerve activation inside the joint. In this study, we developed an injectable nanomedicine, LAC, that responds to the acidic environment of osteoarthritic joints to locally release two approved drugs, reducing inflammation, limiting ...
