Fractal characterizations of MeV ion treated CaF thin films.

We present the morphological evolution and fractal characterizations of CaF thin-film surfaces modified by bombardment with 100 MeV Au ions at various fluences. Atomic force microscopy (AFM) combined with line profile and two-dimensional power spectral density (2D-PSD) analysis was utilized to investigate the evolution of surface morphology as a function of fluence. The AFM images were utilized to investigate the relationship between fractal dimension, roughness exponent, lateral correlation length, and ion fluence.

Carbonate treated coffee powder (CTCP) for selective sorption of Pu over Am, Np, NpO, and PuO from aqueous acidic solution: Investigation on mechanism, kinetics, thermodynamics, stripping and radiolytic stability.

An attempt was made for understanding the sorption behaviour of different actinide ions Pu, PuO, Am, Np, and NpO on carbonate treated exhausted coffee powder (CTCP). Very efficient sorption of Pu over other actinide ions from aqueous acidic medium was observed. Almost 4 h were required for achieving equilibrium.

Giant Orbital Anisotropy with Strong Spin-Orbit Coupling Established at the Pseudomorphic Interface of the Co/Pd Superlattice.

Orbital anisotropy at interfaces in magnetic heterostructures has been key to pioneering spin-orbit-related phenomena. However, modulating the interface's electronic structure to make it abnormally asymmetric has been challenging because of lack of appropriate methods. Here, the authors report that low-energy proton irradiation achieves a strong level of inversion asymmetry and unusual strain at interfaces in [Co/Pd] superlattices through nondestructive, selective removal of oxygen from Co O /Pd superlattices during irradiation.

Enhanced Spin-to-Charge Conversion Efficiency in Ultrathin BiSe Observed by Spintronic Terahertz Spectroscopy.

Owing to their remarkable spin-charge conversion (SCC) efficiency, topological insulators (TIs) are the most attractive candidates for spin-orbit torque generators. The simple method of enhancing SCC efficiency is to reduce the thickness of TI films to minimize the trivial bulk contribution. However, when the thickness reaches the ultrathin regime, the SCC efficiency decreases owing to intersurface hybridization.

Impact of Spin-Orbit Torque on Spin-Transfer Torque Switching in Magnetic Tunnel Junctions.

The paper presents our simulated results showing the substantial improvement of both switching speed and energy consumption in a perpendicular magnetic tunnel junction (p-MTJ), a core unit of Spin-Transfer-Torque Magnetic Random Access Memory (STT-MRAM), by the help of additional Spin-Orbit-Torque (SOT) write pulse current (WP). An STT-SOT hybrid torque module for OOMMF simulation is implemented to investigate the switching behavior of a 20 nm cell in the p-MTJ. We found that the assistance of WP to STT write pulse current (WP) have a huge influence on the switching behavior of the free layer in the p-MTJ.

Grading of Extraction and Its Relationship with Post-operative Pain and Trismus, along with Proposed Grading for Trismus.

Background: Extraction of mandibular third molars are somewhat a matter of interest because of its malpositioning , curved roots, proximity to vital structures due to this the procedure is often associated with post operative complications like pain and trismus. The extraction of third molar was classified in four grads according to the difficulty of the procedure.

Aims: The purpose of this paper is to find any significant relationship between grading of extraction and post operative complications like pain and trismus.

Significance of radiological variables studied on orthopantamogram to pridict post-operative inferior alveoler nerve paresthesia after third molar extraction.

Context: Removal of impacted third molar is a procedure that is often associated with post-operative complications. The rate of complications is somewhat high because of its proximity to the vital structures. Inferior alveolar nerve paresthesia is one of the common complications of impacted their molar surgery.

Adenoid cystic carcinoma of buccal mucosa.

Adenoid cystic carcinoma is a malignant neoplasm most commonly originating in salivary glands of head and neck region. Here we present a case report of a 50 year old male who was diagnosed with adenoid cystic carcinoma of the right buccal mucosa. The peculiarity of the lesion and the approach we made is the key factor in the presentation.
