Frequency-dependent shear and bulk viscosity of aqueous and non-aqueous lithium battery electrolytes
Transverse ultrasound was used to examine the frequency-dependent shear viscosities of three lithium bis(trifluoromethanesulfonyl)imide-based electrolytes: aqueous, non-aqueous, and hybrid aqueous-organic solutions. Frequency-dependent bulk viscosities of two of the electrolytes...

Harnessing endogenous carbon monoxide for cancer-selective drug synthesis
Synthetic chemistry within living systems offers a transformative strategy for precision medicine by enabling the targeted generation of therapeutic agents directly at disease sites. Carbon monoxide (CO), an endogenous gasotransmitter upregulated in many cancer phenotypes, repres...

Impact of Inhibitor Size and Flexibility on the Binding Pathways to c-Src Kinase
Abstract The conformational plasticity of protein kinases poses a challenge for inhibitor design, motivating the use of molecular dynamics (MD) simulations to study their dynamic binding processes. While conformational changes are increasingly discussed, the impact of drug compou...

Strong coupling between RF photons and plasmons of electrons on liquid helium
Plasmons, arising from the collective motion of electrons, can interact strongly with electromagnetic fields or photons; this capability has been exploited across a broad range of applications, from chemical reactivity to biosensing. Recently, there has been growing interest in p...

A tale of ten cities: data bias in human mobility is pervasive and highly location specific
Abstract Large-scale human mobility datasets play increasingly critical roles in many algorithmic systems, business processes, and policy decisions. Unfortunately, there has been little focus on understanding bias and other fundamental shortcomings of these datasets and how they...

Atomic-precision π-driven peptide hydrogel nanofibers with ordered water channels
Aromatic interactions organize molecules into ordered supramolecular architectures, while peptides form functional soft materials through hydrogen bonding and water-mediated assembly. In peptide-based systems, strong aromatic stacking is typically achieved by terminal capping, wh...
