Thermodynamics and Entropy Loss in Nanoconfined Chain Polymerization

open access: yesJournal of Polymer Science, EarlyView.
The difference in the entropy change on propagation in nanoconfined and bulk free‐radical polymerizations is 1–2 orders of magnitude larger than the conformational entropy lost in confined SAW simulations. The experimental confinement entropy is also super‐extensive in chain length scaling, suggesting that the difference between experiments and ...

Herbaria as repositories of past soil properties and historical soil DNA

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Soil health is fundamental to agriculture, food security, and the sustainable management of terrestrial ecosystems under ongoing climate and land‐use changes. Soil microorganisms play a key role in these processes, yet how soils and their microbial communities have changed over time in response to global environmental change remains poorly understood ...

Two centuries of Begonia exploration in the Philippines: Progress and challenges associated with a megadiverse genus in the Global South

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Megadiverse genera represent the highest concentration of plant diversity, but these plants are also located primarily in countries in the Global South where huge gaps in botanical knowledge remain. This study summarized two centuries of Begonia collection records in the Philippines to show how historical events coincide with collection and taxonomic ...

Investigation of the laser fluence and wavelength dependence in surface‐assisted laser desorption/ionization mass spectrometry using gold nanoparticles

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
Rationale Surface‐assisted laser desorption/ionization (SALDI) mass spectrometry (MS) builds on the use of nanostructured surfaces (e.g., coatings of colloidal nanoparticles) to promote analyte desorption and ionization. The SALDI process is believed to occur mainly through thermal processes, resulting from heating of the nanosubstrate upon absorption ...

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...
