Synthetic Thermo‐Sensitive Hydrogel Microspheres as Temperature Probes in an Optical Tweezers Setup

open access: yesChemistry–Methods, EarlyView.
We demonstrate the use of thermo‐sensitive poly‐NIPAAm microspheres as temperature probes to quantify the heating induced by a high‐power optical tweezers laser. The probes can estimate the temperature with an accuracy of 1–2 °C in the biologically relevant range and can be easily incorporated within biological optical tweezers assays to help avoid ...

Capturing Electrochemically Galvanic Exchange Events between Silver and Gold in Nonequilibrium and Equilibrium Realms

open access: yesChemistry–Methods, EarlyView.
A new methodology is presented to study the kinetics of the galvanic replacement reaction between silver and gold, allowing, for the first time to our knowledge, real‐time monitoring of the dynamics of this redox reaction by quantifying the main driving force, that is, the time‐ and concentration‐dependent redox potential, which cannot be captured by ...

Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

open access: yesChemPhysChem, EarlyView.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Vibrational Partition Functions from Bond Order and Populations Relationships

open access: yesChemPhysChem, EarlyView.
A new computational model is presented that predicts vibrational partition functions using bond orders and populations relationships (QBOP). This model demonstrates that thermochemical energy contributions can be reasonably approximated based on well‐conditioned orbital populations without the need for a costly Hessian calculation.
