Process engineering of demineralisation of moderate to high ash Indian coals through NaOH-HCl leaching and HF leaching

open access: yesInternational Journal of Coal Science & Technology
Chemical leaching of coals would be required to produce cleaner coals for some special applications where physical beneficiation may not be effective enough. This would also help in recovering Li and rare earth metals besides in the sequestration of CO2.

Comparative Evaluation of Enamel Surface Roughness after Minimally Invasive Treatment of White Spot Lesions: An In-vitro Experimental Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Introduction: White Spot Lesions (WSLs) represent the initial demineralisation of enamel. In the past, invasive treatment methods required the removal of marginal tissue, which weakened the residual tooth structure.

Bioactivation and Metabolism of Amino Acid MDMA Prodrugs in Zebrafish Embryos, Human Liver S9, Whole Blood, and Microdosed Human Urine

open access: yesDrug Testing and Analysis, EarlyView.
Bioactivation and metabolism of MDMA prodrugs: MDMA‐Trp, MDMA‐Lys, MDMA‐Gly showed unique urine screening targets only for MDMA‐Trp, while biomarkers for MDMA‐Lys and MDMA‐Gly consisted of MDMA and known MDMA metabolites. Conversion of amino acid prodrugs to MDMA in pHLS9, zebrafish embryos, and humans. ABSTRACT 3,4‐Methylenedioxymethamphetamine (MDMA)

Corrosion and wear in moulding boxes [PDF]

open access: yes, 1997
We assess the potential causes of damage to mould box ends and find that both HOT corrosion, due to burning of emitted volatiles, and COLD corrosion, due to the presence of high humidity (and possibly high chloride ion concentration), are likely to ...

The use of demineralisation and torrefaction to improve the properties of biomass intended as a feedstock for fast pyrolysis [PDF]

open access: yes, 2009
Pre-treatments of biomass were investigated to reduce its undesirable properties which may affect the quality of fast pyrolysis bio-oil. A pre-treatment sequence was developed in this study to incorporate both biomass demineralisation and torrefaction.

Streptozotocin induced hyperglycemia in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
