Controlling Valence Band for Cu2Sn0.38Ge0.62S3 Particles via Li Substitution at Cu Sites

Abstract Cu2(Sn,Ge)S3 (CTGS) is a promising near-infrared-responsive photocathode material whose conduction band minimum can be tuned by varying the Sn/Ge ratio, whereas direct control of the valence band maximum (VBM) remains challenging because of the large Cu 3d contribution t...

A Programmable Nanovesicle Platform for MegapascalPressure Sensing

Abstract Hydrostatic pressure (HP) is a subtle yet pervasive force that shapes chemistry and biology from the ocean floor to living cells─yet real-time HP sensing at the microscale remains elusive. Here, we report pyrene-modified polyionic complex vesicles (Pyr-PICsomes) as a cla...

A ComplexSpin-Transition Thermal Hysteresis Unlockedby Two Competing Symmetry-Breakings

Abstract The spin-crossover material [Fe(NH2trz)3](NO3)2 belongs to the class of 1D triazole-based polymeric SCO complexes. It exhibits a thermal phase transition, with a 28 K wide thermal hysteresis, characterized by phase transition temperatures T↑ = 346 K upon warming and T↓ =...

Coordination-Driven Transport in Chloroaluminate Electrolytes

Abstract Transport in electrolytes reflects both the stability of coordination complexes and their dynamic reorganization through chemical bond association and dissociation. Establishing an atomistic description of how the dynamic coordination governs equilibrium speciation and t...

Pressure-SelectiveMagnetic Switching via SpatiallySeparated Soft Interlayer and Rigid Charge-Transfer Intralayer

Abstract We report a pressure-responsive molecule-based magnet featuring a layered cyanido-bridged Co–W assembly, [{CoII(4-phenoxypyridine)4}3{WV(CN)8}2], exhibiting a distinct pressure-selective magnetic behavior. The compound forms two-dimensional charge-transfer layers with la...

Marine-DegradableParamylon Ethers and Ether–EsterDerivatives with Tunable Thermoplasticity and Controlled DissolutionBehavior

Abstract Paramylon, a β-1,3-glucan from Euglena gracilis, is a promising renewable feedstock for biodegradable plastics, but its dense hydrogen-bonding network limits thermoplastic processing. Methyl paramylon (PaMe), ethyl paramylon (PaEt), and paramylon methyl acetate ether–est...

Synthesis ofUnsymmetrically 1,3,5-TrisubstitutedArenes via Site-Selective Sequential Silylation and Borylation

Abstract A catalytic, site-selective silylation and borylation sequence allows the synthesis of unsymmetrically 1,3,5-trisubstituted arenes. A spirobipyridine ligand bearing a “steric roof”, in combination with iridium creates a catalyst that recognizes the shape of a monosubstit...

Two stress-responsive kinases suppress ferroptosis by activating antioxidant programs under mild oxidative stress

Cancer cells maintain chronically elevated levels of reactive oxygen species (ROS) while relying on robust antioxidant programs to preserve redox homeostasis and viability. Although therapeutic strategies that disrupt this balance to induce lethal oxidative stress and ferroptosis...
