The transitional plasticity of ammonium chloride [PDF]

open access: yesJournal de Physique Lettres, 1979
From a phenomenological theory of domain kinetics in a coherent two-phase field it is inferred that the creep rate at the start of macroplastic deformation goes to zero, as the temperature approaches the singular point of the thermal relaxation time.

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

open access: yesAdvanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

Unravelling the surface chemistry of metal oxide nanocrystals, the role of acids and bases [PDF]

open access: yes, 2014
We synthesized HfO2 nanocrystals from HfCl4 using a surfactant-free solvothermal process in benzyl alcohol and found that the resulting nanocrystals could be transferred to nonpolar media using a mixture of carboxylic acids and amines.

From Low Symmetry to High Dissymmetry: Chiral Plasmonic Films of Binary and Nanobipyramid Assemblies

open access: yesAdvanced Functional Materials, EarlyView.
This work develops highly dissymmetric chiral plasmonic thin films by helically assembling gold nano bipyramids within a liquid‐crystal template. Engineering of the chiroptical response is achieved by varying particle size and geometry, as well as preparing binary assemblies.

Bactericidal, protistocidal and nematodicidal properties of mixtures of alkyldimethylbenzyl ammonium chloride, didecyldimethyl ammonium chloride, glutaraldehyde and formaldehyde

open access: yesRegulatory Mechanisms in Biosystems, 2018
We conducted a comparative analysis of the impact of disinfecting preparations on the cryogenic stains of microorganisms, and also on Haemonchus contortus (Rudolphi 1803), invasive larvae of the ruminants.
