Published: April 2015

The reiterative high temperature co-sublimation of an enantiopure or an enantioenriched α-amino acid mixed with racemic α-amino acids leads to deracemization of the latter. A synergistic effect is observed for complex mixtures, and the sense of the handedness is, for all compounds, identical to that of the enantioenriched starting material.

Purpose Of Review: This review aims to evaluate current diagnostic and therapeutic strategies for postpericardiotomy syndrome (PPS), with a focus on the evolving role of multimodality imaging, including echocardiography, cardiac computed tomography (CCT), and cardiac magnetic resonance imaging (CMR). The review also explores the potential benefits of advanced imaging in improving the accuracy and management of PPS.

Recent Findings: PPS, a common complication following cardiac surgery, presents with pleuritic chest pain, fever, and pericardial or pleural effusion.

High-Performance Thermoelectric Composite of BiTe Nanosheets and Carbon Aerogel for Harvesting of Environmental Electromagnetic Energy.

ACS Nano

Intensifying the severity of electromagnetic (EM) pollution in the environment represents a significant threat to human health and results in considerable energy wastage. Here, we provide a strategy for electricity generation from heat generated by electromagnetic wave radiation captured from the surrounding environment that can reduce the level of electromagnetic pollution while alleviating the energy crisis. We prepared a porous, elastomeric, and lightweight BiTe/carbon aerogel (CN@BiTe) by a simple strategy of induced in situ growth of BiTe nanosheets with three-dimensional (3D) carbon structure, realizing the coupling of electromagnetic wave absorption (EMA) and thermoelectric (TE) properties.

Finding novel efficient nonlinear optical materials with large second-order nonlinearity for the UV spectral range remains a formidable challenge, especially for silicate systems. Using a high-temperature solid reaction in a tight vacuum environment, two ultraviolet nonlinear optical materials with a moderate second harmonic generation (SHG) response have been created: PbSiOC and PbCaSiO. The SHG values they computed are roughly 2.

Neutrophilic Panniculitis Secondary to BRAF and MEK Inhibitor Therapy to Treat Stage IIIa Cutaneous Melanoma.

Department of Dermatology, San Antonio Uniformed Services Health Consortium (SAUSHEC), San Antonio, Texas, USA.

Panniculitides are a group of inflammatory disorders of the subcutaneous fat that have been reported as a rare complication of both a serine threonine kinase BRAF inhibitor monotherapy and BRAF inhibition in combination with a mitogen activated protein kinase (MEK) inhibitor combination therapy used to treat metastatic melanoma. The cutaneous manifestations of BRAF and BRAF/MEK therapies have been well documented, but neutrophilic panniculitis remains a less common complication with fewer case reports. Physician awareness of this complication when following patients on similar targeted therapies can decrease delays in appropriate management.

Interface Modification by GaO Atomic Layers within Er-Doped GeO Nanofilms for Enhanced Electroluminescence and Operation Stability.

ACS Appl Mater Interfaces

School of Materials Science and Engineering, Tianjin Key Lab for Rare Earth Materials and Applications, Nankai University, Tianjin 300350, China.

For silicon-based devices using dielectric oxides doped with rare earth ions, their electroluminescence (EL) performance relies on the sufficient carrier injection. In this work, the atomic GaO layers are inserted within the Er-doped GeO nanofilms fabricated by atomic layer deposition (ALD). Both Ga(CH) and Ga(CH) could realize the ALD growth of GaO onto the as-deposited GeO nanofilm with unaffected deposition rates.
