The RNA-condensate interface study measures in-vitro RNA/PEG systems and compares interface behavior with molecular modeling.
Empirical findingChemistryCondensate function versus correlated assemblyAssembly, partitioning and a cellular phenotype do not alone identify whether phase separation causally produces that phenotype.
Open questionChemistryTernary degradation complexes and independent controlsGadd and colleagues resolved a Brd4 bromodomain–MZ1–VHL complex and combined binding, mutagenesis, proximity and cell-protein measurements.
Empirical findingPhysics · ChemistrySurface tension and capillary riseInterface forces can support pressure jumps and capillary columns.
ModelPhysics · ChemistryHeat, temperature and specific heatHeat is energy transferred because of a temperature difference.
ModelPhysics · ChemistryPressure–volume work and process pathsBoundary work depends on the process, while internal energy is a state function.
ModelPhysics · ChemistryReversible adiabatic ideal-gas relationsThe power law needs an ideal gas and constant heat-capacity ratio.
ModelPhysics · ChemistryReversible and quasistatic processesRestoring the system alone does not establish reversibility.
ModelPhysics · ChemistryEntropy change and reversible heat transferUse a reversible comparison path to calculate a state-function change.
ModelPhysics · ChemistryMean free path in a dilute hard-sphere gasA collision length depends on number density and cross section.
ModelMeasurement · ChemistrySelectivity of a measuring systemResponding to a target differs from excluding interference.
DefinitionChemistrySubstances, elements, compounds and mixturesChemical composition and spatial uniformity describe different features of matter.
DefinitionChemistryPhysical change and chemical changeA change of phase need not change chemical identity.
DefinitionChemistryEmpirical, molecular and structural formulasA formula's subscripts represent different information in different chemical models.
DefinitionChemistry · PhysicsIntensive, extensive, specific and molar propertiesScaling the system amount is different from changing its state.
DefinitionChemistry · MeasurementRelative atomic mass and isotope compositionRelative atomic mass is dimensionless and depends on the isotope composition being averaged.
DefinitionChemistry · MeasurementMolar mass and mass–amount conversionMolar mass converts a specified substance's amount into mass.
DefinitionChemistry · MeasurementAmount concentration, molality and composition fractionsConcentration must declare its numerator and denominator.
DefinitionChemistryDilution conserves the retained solute amountDilution arithmetic refers to final solution volume, not the amount of solvent poured in.
MethodChemistryLimiting reagent, theoretical yield and percent yieldStoichiometry gives a maximum under a specified reaction model; recovery measures the actual yield.
MethodChemistryFormal charge is equal-share electron accountingFormal charge, oxidation state and partial charge answer different questions.
DefinitionChemistryElectrolyte strength, solubility and concentrationStrong describes ion formation by dissolved solute, not how much solute dissolves.
DefinitionChemistryComplete ionic and net ionic equationsCancel unchanged species while conserving both atoms and charge.
MethodBiology · ChemistryWater polarity and biological interactionsWater's molecular interactions help explain solvation, cohesion and thermal buffering.
Empirical findingBiology · ChemistryOsmolarity and tonicityTotal particle concentration and lasting cell-volume effect are different properties.
DefinitionBiology · ChemistryPlant water potential and pressure balanceOsmotic and mechanical contributions together determine passive water movement.
ModelPhysics · ChemistryOpen, closed, isolated and adiabatic systemsA system boundary determines which transfers count as exchanges.
DefinitionMeasurement · Physics · ChemistryCommon non-SI units and exact SI conversionsCommon non-SI unit names require their correct SI scale factors.
DefinitionPhysics · ChemistryGas pressure as molecular momentum transferMolecular collisions link macroscopic pressure to random translational motion.
ModelChemistry · PhysicsOrdinary aggregate states and bulk behaviorSolid, liquid and gas describe bulk behavior rather than chemical identity.
