Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

Emulsifiers of Pickering-like characteristics at fluid interfaces:Impact on oil-in-water emulsion stability and interfacial transfer rate kinetics for the release of a hydrophobic model active [PDF]

, 2020
The influence of interfacial layer composition on the release kinetics of a model hydrophobic active (dimethyl phthalate, DMP) from oil-in-water (o/w) emulsions relevant to foods is reported.

Understanding the Stability of Poorly Covered Pickering Emulsions Using on‐Chip Microfluidics

Advanced Science
Particle‐stabilized emulsions, also known as Pickering emulsions, have shown promise in areas that require long‐term stability with minimum use of surfactants.

Preparation of Pickering Emulsion Stabilized by Cellulose Nanocrystals and Gelatin and Their Emulsification Characteristics

Shipin gongye ke-ji
Cellulose nanocrystals (CNC) are rod-shaped, nanoscale colloidal particles. Their strong hydrophilicity and the single functional group structure seriously have limited potential utilization in stabilizing Pickering emulsions. This study aimed to improve

Word Predictability as a Measure of Second Language Proficiency

Language Learning, EarlyView.
Abstract This study introduces predictabilityBERT, a novel metric for assessing second language (L2) proficiency based on the predictability of word choices in learner language production. Using BERT (Devlin et al., 2019), we calculated the conditional probability of each word in a text given its surrounding context.

Preparation and Properties of Walnut Protein Isolate-Anthocyanin Stabilized Pickering Emulsion

Shipin gongye ke-ji
Composite particles were prepared from walnut protein isolate (WalPI) and anthocyanin (ACN), and used to stabilize Pickering emulsions. The effects of different ACN additions (0.05%~0.15%) on the particle size, zeta potential, Fourier transform infrared ...

Biocatalytic nanoparticles for the stabilization of degassed single electron transfer-living radical pickering emulsion polymerizations

Nature Communications, 2020
The use of solid particles to stabilize Pickering emulsions is a particularly attractive avenue, but oxygen sensitivity remains an obstacle in controlled polymerization reactions.

Concurrent Measurement of O2 Production and Isoprene Emission During Photosynthesis: Pros, Cons and Metabolic Implications of Responses to Light, CO2 and Temperature

Plant, Cell &Environment, EarlyView.
ABSTRACT Traditional leaf gas exchange experiments have focused on net CO2 exchange (Anet). Here, using California poplar (Populus trichocarpa), we coupled measurements of net oxygen production (NOP), isoprene emissions and δ18O in O2 to traditional CO2/H2O gas exchange with chlorophyll fluorescence, and measured light, CO2 and temperature response ...

Modeling the Adsorption of Polydispersed Cellulose Nanocrystals on Emulsion Oil Droplets during Their Simultaneous Breakage and Coalescence

, 2022
Despite efforts to optimize the Pickering emulsification process via various experimental and computational approaches, none delved into the dynamic inter-relationship between the fundamental phenomena that make up this process (i.e., droplet breakage ...

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style

Renaissance Studies, EarlyView.
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral
