Analysis of Trace Impurities in Lithium Carbonate.

Lithium carbonate (LiCO) is a critical raw material in cathode material production, a core of Li-ion battery manufacturing. The quality of this material significantly influences its market value, with impurities potentially affecting Li-ion battery performance and longevity. While the importance of impurity analysis is acknowledged by suppliers and manufacturers of battery materials, reports on elemental analysis of trace impurities in LiCO salt are scarce.

The importance of the pretreatment of samples in Nd quantification from NdFeB magnets through inductively coupled plasma atomic emission spectroscopy (ICP-OES)-a rapid and streamlined methodology.

In this study, we emphasize the critical role of sample pretreatment. We report on the behavior of NdFeB magnet samples exposed to four different acid media for digestion. NdFeB magnets are becoming a significant source of neodymium, a rare-earth element critical to many technologies and a potential substitute for traditional mining of the element.

Effect of Aloe vera gel coating on organoleptic and nutritional quality of minimally processed carrot.

Demand for fresh vegetables has led to development studies in postharvest area mainly focused on minimizing and look for alternatives to chemical additives for food preservation. The use of natural derived edible coatings emerges as a promising alternative for maintaining quality of vegetables. The objective of this study was to evaluate the effect of Aloe vera gel in minimally processed carrot during postharvest storage.

Mean platelet volume and mean platelet volume to platelet count ratio as predictors of severity and mortality in sepsis.

Introduction: Sepsis is a public health problem due to its high prevalence and mortality. Mean platelet volume (MPV), a biomarker reported in routine blood counts, has been investigated and shows promise for determining fatal outcomes in septic patients.

Objective: Evaluate whether the mean platelet volume (MPV) and mean platelet volume-to-platelet count (MPV/P) ratio are predictors of clinical severity and mortality in patients with sepsis.

[Congenital Horner syndrome. Case report].

Horner syndrome is characterized by the following triad of clinical signs: miosis, ptosis and facial anhidrosis. In addition, iris heterochromia, conjunctival injection, facial erythema, congestive nasal mucosa and apparent enophthalmos secondary to the reduction of the palpebral fissure can appear. It is caused by an interruption of the sympathetic pathway that extends from the hypothalamus to the orbit.
