4-(Acetylamino)phenyl benzenesulfonate

Acta Crystallographica Section E Structure Reports Online, 2007
The phenyl and acetyl­amino­phenyl rings of the title compound, C14H13NO4S, are at an angle of 71.57 (5)°, with the acetyl­amino group rotated by 16.3 (1)° from coplanarity with the ring to which it is attached. The structure is stabilized by the presence of N—H⋯O hydrogen bonds which create infinite one-dimensional chains along [010]; weak C—H⋯O inter­

Economic Comparison of Standard Method with E.Jurdo Simplified Method to Measure Linear Alkyl Benzenesulfonates in Municipal Wastewater [PDF]

سلامت و محیط, 2011
Background and Objectives: Linear alkyl benzene sulfonates are widely used as surfactants in formulated detergent products. Because of their use in household and industrial detergents, LAS is discharged into wastewater collection systems and subsequently

The Mechanism of the Alkaline Fusion of Benzenesulfonic Acid. [PDF]

Bulletin of the Chemical Society of Japan, 1966
Abstract Benzenesulfonic acid-1-14C was fused with potassium hydroxide at 320—350°C for five minutes. The phenol obtained was then degraded as usual, and the distribution of carbon-14 in the phenol was determined. Practically all the 14C activity was found at the 1 position of the phenol, which means that there is no migration of the 14C

Fluorinated copolymer resists for high‐resolution negative‐tone lithography: Preparation and patterning performance

Smart Molecules, EarlyView.
Electron‐beam induced C–F cleavage in –CF3 generates F−, which abstracts a proton to form the acid that catalyzes tBMA deprotection during post‐exposure baking. This self‐sensitization mechanism enables the precise formation of high‐resolution negative‐tone patterns with enhanced sensitivity and resolution.

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

Smart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, Volume 49, Issue 9, Page 7168-7190, September 2026.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

Self‐Complementary Dimers Based on Zwitterionic Halogen Bond Donors

Chemistry – A European Journal, Volume 32, Issue 27, 17 July 2026.
In this study we present the first isolated zwitterionic homodimers based on halogen bonding (XB). After optimization of the structures by changing the Lewis base (LB) and the backbone, their dimerization was observed in gas phase, as well as, in solid state.

The Binding of Pentadiyl‐α,ω‐Bis(Dimethyldodecylammonium), a Cationic Gemini 12‐5‐12 Surfactant to Conjugated Carboxylates as Organic Counterions

Journal of Surfactants and Detergents, Volume 29, Issue 4, Page 667-676, July 2026.
ABSTRACT The critical micelle concentration (CMC) values of the cationic gemini surfactant pentadiyl‐α,ω‐bis(dimethyldodecylammonium) bromide depend on the hydrophobicity of added conjugated organic carboxylate anions. Nine conjugated counterions, present as sodium salts of organic acids, were studied to expand the correlation to the counterion ...

One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

Advanced Science, Volume 13, Issue 36, 29 June 2026.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.
