IMMOBILIZATION OF MICROBIAL CELLS FOR THE PRODUCTION OF ORGANIC ACIDS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1990
Techniques of immobilization of microbial- cells have been established by multifunctional reagents such as glutaraldehyed on a solid support. Immobilized cell reactor was designed to demonstrate stability of cross linking of whole cells for the ...

Coordination of Cu(II) and Ni(II) in polymers imprinted so as to optimize amine chelate formation [PDF]

open access: yes, 2003
Molecular imprinting has become an established technique. However, little was done on direct investigation of the sorbents produced. In the present work, en ESR method was used for the investigation of the complex formation processes within the sorbents ...

Stable covalently photo-cross-linked poly(ionic liquid) membrane with gradient pore size

open access: yes, 2017
An imidazolium-based poly(ionic liquid) is covalently cross-linked via UV light-induced thiolene (click) chemistry to yield a stable porous polyelectrolyte membrane with gradients of crosslink density and pore size distribution along its cross-section ...

In vitro culture with gemcitabine augments death receptor and NKG2D ligand expression on tumour cells [PDF]

open access: yes, 2019
Much effort has been made to try to understand the relationship between chemotherapeutic treatment of cancer and the immune system. Whereas much of that focus has been on the direct effect of chemotherapy drugs on immune cells and the release of antigens

Reversibly locked thionucleobase pairs in DNA to study base flipping enzymes

open access: yesBeilstein Journal of Organic Chemistry, 2014
Covalently interstrand cross-linked DNA is an interesting tool to study DNA binding proteins that locally open up the DNA duplex by flipping single bases out of the DNA helix or melting whole stretches of base pairs to perform their function.

Cross-linking of Polystyrene by Friedel–Crafts Chemistry to Improve Thermal Stability [PDF]

open access: yes, 1999
Copolymers which contain either alcohol or chloride functionalized polystyrene units have been prepared and they participate in Friedel–Crafts chemistry to give cross-linked polymers by the evolution of either hydrogen chloride or water.

In vivo evaluation of biocompatibility and biodegradation of porcine collagen membranes

open access: yesRegenerative Therapy
Introduction: Collagen-based materials differ in absorption time, biodegradation patterns, and inflammatory cell infiltration. This study aimed to evaluate the biocompatibility and biodegradation of native, differently processed, and cross-linked porcine
