Fabrication and Preparation of Coal-Water Slurry Dispersant with Amphoteric Polycarboxylate

, 2011
Coal-water slurry （CWS）dispersant is a key to prepare fine coal-water slurry. A novel amphoteric polycarboxylic (AmPC) dispersant for CWS was copolymerized in aqueous solution by comonomers methacrylate polyglycol monoester (PA), propylene sulfur sodium (

Improvement of dispersants on nano carbon black-modified cement paste: performance, microstructure and carbon footprint

Frontiers in Materials
The agglomeration of nano carbon black (NCB), driven by its high specific surface energy, limits the fundamental performance of cementitious materials and hinders the broader application of functional cementitious materials in engineering domains.

Accurate Sizing and Resolution of Nominal 200 nm Diameter Polystyrene Nanospheres With Charge Detection Mass Spectrometry

Small, EarlyView.
This study highlights the utility of charge detection mass spectrometry (CDMS) as a high‐throughput nanoparticle characterization tool. CDMS measurements of 200 nm polystyrene size standards are within 1% of those derived from transmission electron microscopy (TEM). Notably, a mixture of three ∼200 nm samples is readily resolved by CDMS but not by TEM,

Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

The Non‐Understandable World of Autism Spectrum Disorder: A Therapist's Implicit Understanding and Subsequent Deepened Understanding

Journal of Analytical Psychology, EarlyView.
Abstract This paper examines the concept of non‐understandable in psychotherapy, based on the author's own play therapy with a boy with mild ASD (autism spectrum disorder). ASD is considered to belong to an area beyond comprehension, as psychotherapy is often deemed ineffective for it.
