High-performance Ni-free sustainable cathode NaMgFeMnO for sodium-ion batteries.

Having in mind the remarkable economic and environmental issues involved in the presence of nickel and cobalt metals in electrode compositions, new NaMgFeNiMnO (x=0.0, 0.05, 0.

Sustainable, low Ni-containing Mg-doped layered oxides as cathodes for sodium-ion batteries.

The supply of battery-grade nickel to produce positive electrodes of sodium-ion batteries may soon become insufficient. For this reason, it is crucial to find new electrode materials that minimize its use or even fully remove this element from synthesis. We have prepared a NaMgFeNiMnO (0 ≤ ≤ 0.

Current status and development of neutron radiation for biophysical applications in Colombia.

In Colombia, medical physics started formally about 3 decades ago. Two master's programs in medical physics initiated activities at two different universities. In particular, the master's program at the Pontificia Universidad Javeriana has been underway since 2012, and taking into account its projections, a team was established in 2015 in collaboration with the Universidad Distrital Francisco José de Caldas to conduct basic research on cancer treatment using neutron capture therapy (NCT).

Mexican radiationdermatitis management consensus.

Background: Radiotherapy (RT) is an essential element in cancer treatment: 50-70% of cancer patients receive RT at some time of the course of their disease. Of these, almost 95% experience some grade of radiation dermatitis (RD). RD can affect patient's quality of life during and after treatment.

Phenolic compounds of Phellinus spp. with antibacterial and antiviral activities.

Phellinus Quél is one of the largest genera of Hymenochaetaceae; it comprises about 220 species widely distributed on Earth. Most Phellinus species are lignicolous mushrooms that accumulate bioactive compounds. This research studied the phenolic composition of Phellinus spp.
