Behaviour of reinforced concrete subjected to reversed-cyclic shear loads

The goal of the presented research is to experimentally investigate the influence of reversed-cyclic pure shear loading on the behaviour of reinforced-concrete elements, and to formulate simple analytical models which capture the defining features of non-m ...

Photocatalytic evaluation of TiO2/nylon systems prepared at different impregnation times

César Pulgarin, Juan Kiwi

TiO2/nylon fabrics were investigated for methanol degradation under UV light irradiation. TiO2 Degussa P-25 was supported on nylon by immersing the nylon in sol-gel TiO2 and silicone. The TiO2 layers on the nylon were explored as a function of the time of ...

Built-in 5-Aminooxazole as an Internal Activator of the Terminal Carboxylic Acid: An Alternative Access to Macrocyclodepsipeptides

Jieping Zhu

A conceptually novel macrolactonization technology is described. A strategically positioned 5-aminooxazole served as an internal traceless activator of the neighboring C-terminal carboxylic acid allowing the occurrence of macrolactonization under mild acid ...

Control of Polymerization Processes

Dominique Bonvin, Grégory François

With an annual worldwide production well in excess of 100 million metric tons, synthetic polymers constitute a significant part of the modern chemical process industry. Polymer reactors - operated in continuous, batch, or semibatch mode - are therefore imp ...

Innovative UVC Light (185 nm) and Radio-Frequency-Plasma Pretreatment of Nylon Surfaces at Atmospheric Pressure and Their Implications in Photocatalytic Processes

César Pulgarin, Juan Kiwi

Innovative pretreatment by UVC light (185 nm) and by radio-frequency (RF) plasma at atmospheric pressure to functionalize the Nylon surface, increasing its bondability toward TiO2, is reported in this study In the case of UVC light pretreatment in air, the ...

Analysis and study of novel terpolymers composed of acrylamide, mono-charged and double-charged cationic monomers

Peter Käuper, Jutta Christine Wandrey, Ricardo Losada Mateo

The composition of novel terpolymers containing acrylamide (A), acryloyloxyethyltrimethylammonium chloride (Q), and bis-1,3(N,N,N-trimethylammonium)-2-propylmethacrylate dichloride (M) was analyzed combining FTIR and potentiometric titration. Calibration w ...

Stamp forming of carbon fibre/PA12 composites - a comparison of a reactive impregnation process and a commingled yarn system

Pierre-Etienne Bourban, Martyn Douglas Wakeman

Two forms of carbon fibre reinforced polyamide 12 (PA12) were compared during non-isothermal stamp forming. The first was a stretch broken commingled yarn woven into a fabric, studied at three initial preconsolidation levels. The second was produced by in ...

5-aminooxazole as an internal traceless activator of C-terminal carboxylic acid: rapid access to diversely functionalized cyclodepsipeptides

Jieping Zhu

A conceptually novel macrolactonization protocol has been developed. It is a domino process involving a sequence of: (1) protonation of 5-aminooxazole leading to the electrophilic iminium salt; (2) trapping of the iminium species by the neighboring C-termi ...

Protein-Functionalized Polymer Brushes

Harm-Anton Klok, Kai Johnsson, Stefano Tugulu, India Christina Sielaff, Anke Arnold

A new strategy for the prepn. of protein-functionalized polymer brushes is reported, which is based on a combination of surface-initiated atom transfer radical polymn. (ATRP), p-nitrophenyl chloroformate activation of the surface hydroxyl groups, and subse ...

Resin transfer moulding of anionically polymerized polyamide 12

Véronique Michaud, Pierre-Etienne Bourban

Liquid composite moulding of Lactam 12 monomer and activating system (APLC12) into satin weave carbon fabrics is investigated, with emphasis on minimising the void content in the final part. The main sources for void formation are identified. The solidific ...
