STUDY OF THERMAL AND ACID STABILITY OF BENTONITE CLAY

open access: yesIndonesian Journal of Chemistry, 2010
The thermal and acid stability of the bentonite clays (Na- and Ca-bentonite) have been tested. The thermal stability testing has been carried out by heating 5 gram of the clays  for five hours at 200, 300 and 500 °C respectively, meanwhile acid stability

Peroxidase from peach fruit: thermal Stability

open access: yesBrazilian Archives of Biology and Technology, 1998
Peroxidase from peach fruit was purified 28.9-fold by DEAE-cellulose, Sephadex G-100 and hydroxylapatite chromatography. The purified enzyme showed only one peak of activity with an optimum pH of 5.0 and temperature of 40ºC.

Thermal stability and creep properties of radiation crosslinked ultra-high molecular weight polyethylene

open access: yesFushe yanjiu yu fushe gongyi xuebao, 2022
The effects of γ-ray irradiation on the thermal stability and creep resistance of ultra-high molecular weight polyethylene (UHMWPE) were studied. First, UHMWPE powder was hot pressed into 1 mm thick sheets using a vulcanization molding machine.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

BACULOVIRUS THERMAL-STABILITY

open access: yes, 2015
1. The effect of different temperature treatments on the thermal stability of three different baculoviruses (1 GV and 2 NPVs) was compared. 2. The tests were carried out using Diatraea saccharalis (sugarcane borer) larvae as a host for the three viruses.

The effects of displacement induced by thermal perturbations on the structure and stability of boundary-layer flows [PDF]

open access: yes, 1996
The free-interaction influence of a thermal expansión process in boundary-layer gas flow is analyzed using the formalism of triple-deck theory. The physical model considered is the forced convection of a gas flowing over a flat plate subject to a heated ...
