Polyethylene Upcycling to Liquid Alkanes in Molten Salts under Neat and External Hydrogen Source-Free Conditions
Researchers found a way to turn single-use plastics (e.g., grocery bags and packaging) into useful liquid fuels, like components of gasoline or diesel, without needing high heat, rare metals, or added chemicals. The work presents a promising pathway to address the global plastic waste crisis, with both environmental and economic advantages. Read more »
Vertical gradient in atmospheric particle phase state: a case study over the alaskan arctic oil fields
Integrating chemical composition and phase state measurements demonstrated that carbonaceous-rich and organic-dominated particles exhibited higher viscosities, while inorganic-rich particles displayed lower viscosities. This finding establishes an association between composition and phase state, offering critical insights into the vertical stratification of Arctic particles. Read more »
Identification of Structurally Novel KRASG12C Inhibitors through Covalent DNA-Encoded Library Screening
DNA-encoded library (DEL) technology was used to prepare a ~1.6 × 107-compound cysteine-reactive library (representative component shown at bottom, cysteine-reactive site indicated). Screening this library against the KRASG12C oncoprotein identified multiple structurally novel inhibitors of this challenging-to-drug target (e.g., frontmost green compound in the X-ray structure at right, covalent bond to KRASG12C indicated).

Operando Unveiling of Hydrogen Spillover Mechanisms on Tungsten Oxide Surfaces
An artistic depiction of hydrogen spillover on Pt/WO3, illustrating H2 activation and dissociation on Pt metal clusters, followed by hydrogen migration to WO3 for water formation. At elevated temperatures, water desorption and surface-to-bulk diffusion of hydrogen drive tungsten redox and oxygen vacancy formation on the surface of WO3. Read more »
Structure of the human autophagy factor EPG5 and the molecular basis of its conserved mode of interaction with Atg8-family proteins
The study reports the first structure of human EPG5 (HsEPG5) determined by cryo-EM and AlphaFold2 modeling. Read more »
Nanoconfinement of High Hydrogen-to-Metal Ratio Lanthanum Hydrides in Functionalized Carbon Hosts
Metal hydrides with a high hydrogen content are important for materials-based hydrogen storage and high-temperature superconductivity. Nanoconfinement of metal hydrides in porous hosts is a promising strategy to tune the thermodynamic stability and control the hydrogen-to-metal ratio. X-ray absorption and photoelectron spectroscopy provided detailed information about the local chemical environment of LaHx species within carbon hosts. Read more »
Local Chemical Enhancement and Gating of Organic Coordinated Ionic-Electronic Transport
Record ion mobility and conductivities are revealed within a nanoscopic interfacial superhighway of an organic mixed ionic-electronic conductor. Fast ion transport can be controlled by hydrophobicity of molecules local to this channel, effectively gating ion access to the superhighway. This mechanism is used in a novel chemical sensing device which detects the dynamics of a local, buried chemical reaction. Read more »
Advancing high-temperature electrostatic energy storage via linker engineering of metal–organic frameworks in polymer nanocomposites
High-performance, thermally resilient polymer dielectrics are essential for film capacitors used in advanced electronic devices and renewable energy systems, particularly at elevated temperatures where conventional polymers fail to perform. Herein, we unravel the untapped potential of UiO-66 metal–organic framework (MOF) derivatives as exceptional nanofillers for tuning the properties of the widely used polyetherimide (PEI). Read more »
Jamming Giant Molecules at Interface in Organic Photovoltaics to Improve Performance and Stability
Giant molecule acceptors (GMAs), known for their large size and intricate functional structures, are an emerging focus in materials science. Through implementation of an interface-enhanced layer-by-layer fabrication strategy, we have successfully demonstrated that GMA with designed electronic structure at interfaces can effectively improve OPV device performance.
