1,1-Dimethylbiguanidium(2+) dinitrate

In the crystal structure of the title compound, C4H13N52+·2NO3−, the main intermolecular interactions are the N—H...O hydrogen bonds between the cationic amino groups and the O atoms of the nitrate ions. All ami...

The Effect of Different Accelerators on the Vulcanization of EPDM Rubber

: EPDM (ethylene propylene diene monomer) is a type of synthetic rubber. The products of rubber have great importance in every part of life. EPDM rubber has high tensile strength, high tension, toughness, and is weather resistant. Therefore...

Glass-fiber catalysts for selective catalytic reduction of nitrogen oxides by CO and hydrocarbons

Glass-fiber catalysts (GFCs) are investigated in the process of the catalytic reduction of nitrogen oxides by hydrocarbons and carbon monoxide contained in waste and flue gases. Studies show that the platinum-based GFCs prepared by surface ...

Characterization of thermally treated polypropylene powders with wide sintering window for powder bed fusion of polymers

One key issue restricting semi-crystalline polymers to be widely applied in powder bed fusion (PBF) of polymers is lack of good powder processability, especially a wide sintering window. In this work, a thermal treatment method with mixed d...

Physicochemical characterization and source apportionment of Arctic ice-nucleating particles observed in Ny-Ålesund in autumn 2019

Ice-nucleating particles (INPs) initiate primary ice formation in Arctic mixed-phase clouds (MPCs), altering cloud radiative properties and modulating precipitation. For atmospheric INPs, the complexity of their spatiotemporal variations, h...

A STRAIGHTFORWARD SYNTHESIS OF NOVEL 1,3,5-TRIAZINE-BASED MACROCYCLIC SCAFFOLDS

The synthesis and structural investigation of a series of three macrocycles bearing 2,4,6-tris(p-phenylene)-1,3,5-triazine central units and oligoethyleneoxide bridges are reported. The approach implied the synthesis of non-symmetrical 1,3,...

Self-Matrix N-Doped Room Temperature Phosphorescent Carbon Dots Triggered by Visible and Ultraviolet Light Dual Modes

The synthesis of room temperature phosphorescent carbon dots (RTP-CDs) without any matrix is important in various applications. In particular, RTP-CDs with dual modes of excitation are more interesting. Here, we successfully synthesized mat...

A comparative life cycle assessment of viscose fibers derived from cotton, wood, and bamboo pulp

In this work, a life cycle assessment (LCA) approach was employed to evaluate the environmental impact of viscose fibers made from cotton, wood and bamboo pulp, in accordance with the ISO 14040 standard. Utilizing SimaPro 9.5.0 software, th...

Sophorolipids Production from Oil Cake by Solid-State Fermentation. Inventory for Economic and Environmental Assessment

Biosurfactants are being proposed as a substitute for surfactants in the framework of a circular economy strategy. Sophorolipids (SL) are a type of biosurfactant produced by yeast that can be produced through submerged or solid-state fermen...

Hornification in Commercial Chemical Pulps: Dependence on Water Removal and Hornification Mechanisms

Understanding cellulose hornification provides crucial information regarding drying of pulp, paper, and other cellulosic materials as well as recycling them. By measuring drainage, fiber width, and water retention value of hardwood and soft...

Triple‐State Invisible Photonic Crystal Pattern Encrypted in Hollow‐Silica/Polyurethane Film for Anticounterfeiting Applications

An invisible photonic crystal (PC) pattern encrypted at the dry state and decrypted by solvent is a new anticounterfeiting material system, but its diversity and complexity in response are still required to be increased to enhance the antic...
