Synthesis of Ferroelectric and Multiferroics Thin films of BiMnO3/ SrTiO3 and Structural, Piezoelectric, Magnetic, Optical, and Mechanical Properties Characterization

Glory Valentine Umoh (2022, [Tesis de doctorado])

Multiferroic characteristics of BiMnO3 thin films offer great prospects to explore, either

in terms of ferroelectricity, ferromagnetism, or ferroelasticity. Ferroelectric and

ferromagnetic materials can be used in data storage due to their electrical and magnetic

properties. Ferroelastic can find its application in microelectromechanical systems

devices. This dissertation focused on the synthesis, characterization, and improvement of

the multiferroic properties of polycrystalline BiMnO3 thin films as well as the elaboration

influence of Cu on the magnetism of BiMnO3 thin films. BiMnO3 films were grown on

three different substrates, Si (001), Pt-buffered Si (001), Nb-doped SrTiO3 (100), and also

doped with different amounts of Cu. The films were characterized using techniques such

as X-Ray diffraction (XRD), scanning electron microscope (SEM), HRTEM

observations, by energy-dispersive X-ray spectroscopy (EDS), atomic force microscopy

(AFM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, Visible-near-IR

spectroscopy (Vis-NIR), electron energy loss spectrometer (EELS), nanoindenter,

superconductor quantum interference device (SQUID) magnetometer, and finally, the

polarization-electric field (P-E) hysteresis loops of the BiMnO3 thin films were conducted

at 200 and 300 K. There are several studies on the growth of thin films, however, they are

not clear and in some cases contradictory, therefore, different parameters were controlled

during the deposition in terms of working pressure, RF power, substrate, deposition

10

temperature, and target to substrate distance. After deposition ex-situ thermal treatment

was carried out in order to compensate for the volatility of bismuth and also to eliminate

secondary phase.

Kramer’s–Krӧnig analysis was used to determine bandgap, via a polynomial fit in the

energy loss function (ELF) plot with an Eg = 1.63 eV, complex dielectric function, and

static dielectric constant, ε* = 4.68 of the grown BiMnO3 thin films. The reflection

coefficient Ґl of the BiMnO3 thin films was used to elucidate the reflection loss in the

BiMnO3 thin films. XPS analysis revealed the existence of Mn charge transition of 3+

and 4+ states. Resistivity result describes BIMnO3 as a semiconductor. The

nanomechanical characterization demonstrated that the region of penetration depth was

below 10% of BiMnO3 film thickness. Young's modulus (E), hardness (H), and Stiffness

(S) were measured to be 142 ± 3 GPa, 8 ± 0.2 GPa, and 44072 ± 45 N/m respec

A new species of Encelia (Compositae, Heliantheae, Enceliinae) from the southern Baja California Peninsula

JOSE LUIS LEON DE LA LUZ Isaac Lichter-Marck (2022, [Artículo])

"Se ilustra y describe a una nueva especie de Asteraceae, Encelia balandra. Se conoce solo de las laderas rocosas de los cerros próximos a puerto Balandra y Pichilingue, dentro de la bahía de La Paz, en Baja California Sur, México. Encontramos que esta nueva especie tiene ciertas semejanzas con otras de Encelia por su hábito semiarbustivo, las flores radiales neutras y cipselas comprimidas con ápice hendido. Confirmamos tal condición con datos de secuencia para las regiones ITS y ETS del genoma. También presentamos fotografías detalladas, un evaluación de conservación, y un clave dichotomus para los Encelia de Baja California sur. Se discute la semejanza con las especies peninsulares más cercanas de Encelia, se presenta una clave dicotómica para los taxonesaustrales de la península de Baja California, y finalmente se muestran imágenes detalladas de esta nueva especie."

"Here, we describe and illustrate Encelia balandra sp. nov., a new species of Compositae from the Baja Cal- ifornia Peninsula. It is rare and known only from the rocky hills around Puerto Balandra and Pichilingüe, inside the bay of La Paz, in the State of Baja California Sur, Mexico. We determine that this new species has affinities with Encelia, based on its suffruticose woody habit, neuter ray florets and compressed disc cypselae with a cleft apex. The taxonomic placement within Encelia is supported by nuclear ribosomal sequence data from two regions, ITS and ETS. We also present detailed photographs, a conservation assessment and a dichotomous key to the Encelia of the southern Baja California Peninsula. Finally, we discuss the uniqueness of Encelia balandra amongst peninsular Encelia and its potential significance for understanding the enigmatic biogeography of this ecologically important genus."

Introduction: the elevation of the transcrestal floor of the maxillary sinus consists of the vertical reconstruction of the atrophic alveolar ridge in an apical direction, with which it is possible to place the correct number and length of oral implants. Objective: to describe the procedure of a case of transcrestal maxillary sinus floor elevation with the placement of three dental implants. Clinical case: 62 year old female patient with missing teeth 16, 25 and 26. Treatment: three implants were placed to replace the missing teeth. Due to the decrease in height of the remaining alveolar ridge due to pneumatization of the maxillary sinuses, elevation of the sinus floor was planned with the transcrestal Summers¿s technique and placement of graft material. Results: by means of the grafts, sufficient height was achieved for the correct stability of the implants, each área had an average gain of 3 mm in bone height, with which length was obtained to give the implants adequate primary stability. Conclusion: sinus floor elevation with a transcrestal approach is a good alternative for rehabilitation with implants in the posterior edentulous sector, associated with pneumatization of the maxillary sinuses.

Hot Extremes and Climatological Drought Indicators in the Transitional Semiarid-Subtropical Region of Sinaloa, Northwest Mexico

OMAR LLANES CARDENAS OSCAR GERARDO GUTIERREZ RUACHO Iván Hernández Romano ENRIQUE TROYO DIEGUEZ (2022, [Artículo])

"The main goal of this study was to explore the historical and recent spatial concurrence between the frequency (F), duration (D) and intensity (I) of hot extremes (HEs) and the frequency and evolution of meteorological drought in the region of Sinaloa. Based on the values of daily maximum temperatura (Tmax) and precipitation obtained from CLImate COMputing for the interval April–October of a historical period (1963–2000) and a recent period (1982–2014), the HE and the standardized precipitation index (SPI) were calculated on one-month (SPI-1) and four-month (SPI-4) timescales. Spearman rank correlation coefficients (Sr) were used to obtain the significant concurrences (SCs) between HEs and SPI-1, and HEs and SPI-4. El Quelite weather station showed the highest historical SCs between HEs and SPI-1 (−0.66≤Sr≤−0.57). Jaina is the only station that showed SCs with all four indicators of HEs and SPI-4 (−0.47≤Sr≤−0.34). In this study, the concurrence between HEs and SPI-1, and HEs and SPI-4 was determined for the first time. These are phenomena that can decrease the crop yield, particularly for rainfed crops such as maize, sesame and sorghum in the region commonly known as “the breadbasket of Mexico."

Factores psicosociales de riesgo y protectores relacionados con la depresión en empleadas bancarias de Morelos

ENEIDA ZAYHURI VILLALOBOS SÁNCHEZ (2023, [Tesis de maestría])

Las nuevas dinámicas laborales en el sector bancario derivadas de la adaptación e

implementación de sistemas tecnológicos, precarización y sobrecarga laboral, de la mano de una cultura organizacional desfavorable, algunas veces violenta, se muestran cada vez más estresantes y asfixiantes para sus empleados. Dichos centros se perciben como fuentes generadoras de factores de riesgo psicosocia como el acoso laboral, estos factores de riesgo pueden ser precursores a la presencia del síndrome de quemarse por el trabajo que en muchas de las ocasiones es premórbido ante la presencia de enfermedades ya sea físicas o psicológicas, como la depresión. En la presente investigación están consideradas estas variables, así como sus antagónicos, es decir, los factores psicosociales protectores como el apoyo social y el reconocimiento; la intención es dar a conocer la presencia de ambos factores, así como la repercusión de éstos en la salud de las trabajadoras del sector bancario del estado de Morelos.
