Research progress on the poisoning behavior of air electrodes and corresponding protection strategies for protonic ceramic cells

Energy Reviews
As next-generation intermediate-temperature electrochemical energy conversion devices, protonic ceramic cells (PCCs) face significant challenges in durability and commercialization due to air electrode poisoning under complex operating conditions.

Synthesis of an aromatic N-heterocycle derived from biomass and its use as a polymer feedstock

Nature Communications, 2019
Aromatic N-heterocyclic compounds are important chemicals, but produced from petroleum. Here the authors show a pyridazine-based compound 6-(4-hydroxy-3-methoxyphenyl)pyridazin-3(2H)-one, used as polymer feedstocks, can be synthesized by a Friedel-Crafts

Ion-exchange Resin Catalyzed Esterification of Lactic Acid with Isopropanol: a Kinetic Study [PDF]

, 2011
The kinetic behavior of esterification of lactic acid with isopropanol over an acidic cation exchange resin, Amberlyst 15, was studied under isothermal condition. Isopropyl lactate synthesized in this reaction is an important pharmaceutical intermediate.

Migration and transformation of the polybutadiene phase in ABS during Fused deposition Modeling: Controlling mechanical anisotropy

Materials & Design
Acrylonitrile-butadiene-styrene (ABS) is extensively utilized in Fused Deposition Modeling (FDM), yet the persistent mechanical anisotropy of printed parts remains a major obstacle. Moving beyond the conventional focus on processing parameters, this work

The dynamic behaviour of a modified polyurethane resin [PDF]

, 2009
The dynamic response of both a pure and nano-reinforced polyurethane replacement resin (PRR) have been investigated using plate impact techniques. Similar U-P-U-S Hugoniot equations of state have been established for both materials, despite the altered ...

Adhesion between the Resin Shell and Composite Resin.

The Journal of Nihon University School of Dentistry, 1992
Adhesiveness between the resin shell and composite resin was examined. As the resin shell, SR-PE-ISOCETTE, made from thermosetting crown and bridge resin, was used. The shear bond strengths between the resin shell and photocurable composite resin bonded by various methods were measured after 1-day of immersion in water at 37 degrees C. Super-bond C & B

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Dielectric flow sensing in resin transfer moulding of carbon fibre reinforced composites. [PDF]

, 2000
An in situ dielectric technique for sensing flow is outlined and shown to be suitable for use in moulding of composites from liquid resins containing continuous conducting fibres. This work builds upon the recent development of a sensor for monitoring

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...
