Summary: The research synthesized a series of para-carborane estrogen receptor agonists with low nanomolar potency, over 200-fold selectivity for ER beta over ER alpha, limited off-target activity against other nuclear receptors, and minimal CYP450 inhibition at very high concentrations. These para-carborane ER beta selective agonists show favorable pharmacological properties compared to clinically developed ER beta agonists, supporting further evaluation of carborane-based selective estrogen receptor modulators.

Summary: This study quantitatively evaluated the contributions of various irradiation-induced defects in boron carbide and proposed a theoretical model without adjustable parameters based on phonon scattering theory. The model was validated using experimental data to predict the thermal conductivity variation under irradiation. Results suggest that substitutional defects and Frenkel defect pairs, rather than helium bubbles, play determining roles in the abrupt degradation of thermal conductivity during burnup.

Summary: This study investigates the feasibility of using hexagonal boron nitride (BN) detectors for the detection of fast neutrons. The BN detector, fabricated from a 90 μm thick BN epilayer, exhibited a detection efficiency of about 0.1% when exposed to fast neutrons ranging from 1 to 9 MeV. The measured mean free path of fast neutrons in BN was approximately 7.6 cm. These findings suggest that incorporating BN with a large thickness can enable the direct detection of thermal to fast neutrons, leveraging the ultrawide bandgap properties of BN. The identification of a single material sensitive to both thermal and fast neutrons holds significant value for the development of neutron detection technologies.

Summary: In this study, a radiation detector made of polycrystalline diamond was characterized by neutron and alpha particle. The detector consisted of a boron-doped/undoped stacked structure, and the alpha particles were irradiated from the B-doped layer side. The results showed that the formation of the B-doped layer modified the band structure at the B-doped/undoped interface, improving signal hole collection.

Summary: This study investigates the possibility of improving the quality factor and (or) inductance of an inductor integrated into CMOS technology by adding magnetic materials around it. The performance improvement is evaluated through 3D numerical simulations on an SOI substrate made in a 28 nm UTBB FDSOI technology. The choice of materials and their design topologies are the main parameters studied, leading to a solution selection based on the final application. The results show significant improvements in inductance and quality factor by using different design topologies and materials.

Summary: This study systematically investigates the formation of NiGeSn and its contact resistivity with GeSn semiconductors. The optimal formation temperature of NiGeSn is found to be 325 degrees C, resulting in a lower contact resistivity on n-GeSn. The study also discusses the elemental diffusion mechanism during the NiGeSn formation. Additionally, GeSn exhibits low contact resistivity at 5 K, making it valuable for optimizing contact technologies for low-power and cryogenic applications.

Summary: The multifrequency capacitance-voltage characteristics of high-k HfO2-based 10-nm bulk n-channel FinFETs were studied in this work. The dispersion observed in the accumulation region with respect to temperature was found to be influenced by the substrate time constant. Multifrequency conductance measurements and the variation in the surface potential quotient of the accumulation region were used to investigate the effect of direct tunneling current. Modifications to the existing accumulation region compact model equations were proposed.

Summary: In this work, we fabricate crossbar arrays of silicon nitride resistive memories on silicon-on-insulator substrate and utilize them to realize multi-ratioed logic circuits. The electrical characterization of the memristors shows their ability of multi-state operation with 12 distinct resistance levels. Based on a dedicated modeling and fitting procedure, a reconfigurable logic based on memristor rationed logic scheme is designed and a crossbar integration methodology is proposed. Furthermore, circuitry aspects are simulated with a calibrated model and power optimization prospects are discussed.
