Monoalcohol‐Directed Shape Control in a Surfactant‐Free Gold Nanoplate Synthesis

open access: yesSmall Methods, EarlyView.
Surfactant‐free monoalcohol syntheses are advantageous in that they yield colloidal nanostructures that are free of persistent shape‐directing agents but at the expense of realizing only spherically‐shaped nanoparticles. In this work, this limitation is overcome using a low‐complexity light‐driven synthetic protocol yielding periodic arrays of gold ...

Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

open access: yessteel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Engineering Thermochemistry and Process Technologies to Enable Gigaton‐Scale Sustainable Biochar Production

open access: yesSusMat, EarlyView.
This review examines large‐scale biochar production technologies and process engineering from an engineering thermochemistry perspective. At the level of thermochemical fundamentals, we discuss thermochemical techniques, pyrolysis mechanisms, and key parameters governing biochar formation.

A WORLD OF CONTINGENCIES

open access: yesZygon, 2013
Physicalism holds that the laws of physics are inviolable and ubiquitous and thereby account for all of reality. Laws leave no “wiggle room” or “gaps” for action by numinous agents.

Peptide‐directed nanovehicles enabling tumor‐selective ROS amplification and antitumor immunity

open access: yesVIEW, EarlyView.
Cancer cells are vulnerable to oxidative stress, yet exploit immune tolerance to escape destruction. In contrast, their metabolic profile is markedly altered to support rapid proliferation, accompanied by elevated production of reactive oxygen species (ROS).

Pom1 gradient buffering through intermolecular auto‐phosphorylation

open access: yesMolecular Systems Biology, 2015
Concentration gradients provide spatial information for tissue patterning and cell organization, and their robustness under natural fluctuations is an evolutionary advantage.

Coarse‐Grained Molecular Dynamics Simulations of Oxidative Aging and Stabilization in Polymer Melts With Primary Antioxidants: Effects of Antioxidant Concentration and Molecular Architecture

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Antioxidant type and concentration govern both the rate and spatial heterogeneity of oxidative aging in polymer melts. Higher antioxidant‐group concentration prolongs the induction and reaction time scales, while the BHT‐type antioxidant provides stronger and more homogeneous stabilization than the Irganox1010‐type antioxidant because of its more ...

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

open access: yesJournal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...
