Seeded‐Growth of ZIF‐8 onto Magnetic Nanoparticles: Smart Nanocarriers with Ultrahigh Drug Loading for AMF‐Triggered Release

Small, EarlyView.
We developed core‐shell iron oxide@ZIF‐8 magnetic‐MOF nanohybrids via a seeded growth method for magnetic hyperthermia‐triggered drug delivery. Cubic cores and thinner shells maximized heating. In‐situ doxorubicin encapsulation achieved 98% loading, better than surface encapsulation. Polymer coating improved stability.

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Fractional Poisson Process for Estimation of Capacity Degradation in Li-Ion Batteries by Walk Sequences

Fractal and Fractional
Each charging/discharging cycle leads to a gradual decrease in the battery’s capacity. The degradation of capacity in lithium-ion batteries represents a non-monotonous process with random jumps.

Chemical and Biological Determinants of PEG‐Lipid Shedding From Therapeutic Nanoparticles

Small, EarlyView.
PEG‐lipids play a central role in governing lipid nanoparticle stability, targeting, and function. However, PEG‐lipids can “shed” from the nanoparticle surface in biological environments, with the extent and kinetics of shedding influenced by chemical and biological factors.

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Microfluidic Sample Compartmentalization for Biomolecular Concentration Quantification Using a Nanopore Sensor

Small Methods, EarlyView.
We compartmentalize samples into picoliter volumes using a microfluidic device, allowing us to determine biomolecular concentration by counting molecules to depletion within a known volume without calibration. By integrating a nanopore sensor for this counting process, we also obtain real‐time data on the size, shape, and conformation of each ...

Hurst exponents, Markov processes, and fractional Brownian motion [PDF]

There is much confusion in the literature over Hurst exponents. Recently, we took a step in the direction of eliminating some of the confusion. One purpose of this paper is to illustrate the difference between fBm on the one hand and Gaussian Markov ...
