Inflating type occupant restraint device

Abstract: A receiving case for receiving a gas bag is formed of a side wall portion secured to a fixed member and a lid surface portion thinner than the side wall portion by the use of a material having a comparatively high hardness and a ductility. Further, the lid surface portion is formed with fragile portions contiguous to one another. At the inflation of the gas bag, the receiving case for the gas bag is prevented from scattering in the form of broken pieces, and the gas bag is prevented from being damaged by a sharp edge otherwise arising at the fracture surface of the receiving case.

Nanostructured Ceria−Silver Synthesized in a One-Pot Redox Reaction Catalyzes Carbon Oxidation

Abstract: We introduce a new concept for a nanomaterial in terms of both synthesis and properties. The nanomaterial, aggregates of ceria particles around central silver metal (CeO2−Ag), was fabricated by a one-pot selective redox reaction using cerium(III) and silver(I) autocatalyzed by silver metal without the need for surfactants or organic compounds. This unique nanostructure is suitable as a catalyst, in contrast to core−shell materials wherein the shell deactivates the catalyst metal. The material was developed to be intimately related to catalytic carbon oxidation.

Activity and stability trends of perovskite oxides for oxygen evolution catalysis at neutral pH

Abstract: Perovskite oxides (ABO3) have been studied extensively to promote the kinetics of the oxygen evolution reaction (OER) in alkaline electrolytes. However, developing highly active catalysts for OER at near-neutral pH is desirable for many photoelectrochemical/electrochemical devices. In this paper, we systematically studied the activity and stability of well-known perovskite oxides for OER at pH 7. Previous activity descriptors established for perovskite oxides at pH 13, such as having an eg occupancy close to unity or having an O p-band center close to Fermi level, were shown to scale with OER activity at pH 7. Stability was a greater challenge at pH 7 than at pH 13, where two different modes of instability were identified from combined transmission electron microscopy and density functional theory analyses. Perovskites with O p-band close to Fermi level showed leaching of A-site atoms and surface amorphization under all overpotentials examined at pH 7, while those with O p-band far from Fermi level were stable under low OER current/potential but became unstable at high current/potential accompanied by leaching of B-site atoms. Therefore, efforts are needed to enhance the activity and stability of perovskites against A-site or B-site loss if used at neutral pH.

Trends in Oral Anticoagulant Choice for Acute Stroke Patients with Nonvalvular Atrial Fibrillation in Japan: The SAMURAI-NVAF Study

Abstract: BackgroundLarge clinical trials are lack of data on non-vitamin K antagonist oral anticoagulants for acute stroke patients.AimTo evaluate the choice of oral anticoagulants at acute hospital discharge in stroke patients with nonvalvular atrial fibrillation and clarify the underlying characteristics potentially affecting that choice using the multicenter Stroke Acute Management with Urgent Risk-factor Assessment and Improvement-NVAF registry (ClinicalTrials.gov NCT01581502).MethodThe study included 1192 acute ischemic stroke/transient ischemic attack patients with nonvalvular atrial fibrillation (527 women, 77·7 ± 9·9 years old) between September 2011 and March 2014, during which three nonvitamin K antagonist oral anticoagulant oral anticoagulants were approved for clinical use. Oral anticoagulant choice at hospital discharge (median 23-day stay) was assessed.ResultsWarfarin was chosen for 650 patients, dabigatran for 203, rivaroxaban for 238, and apixaban for 25. Over the three 10-month observation periods...

Atomic Layer Deposition of Lithium Phosphorus Oxynitride

Abstract: An atomic layer deposition (ALD) process is successfully developed for fabricating high-quality lithium phosphorus oxynitride (LiPON) thin films for a potential use as a conformal solid-state electrolyte coating in 3D Li-ion microbattery technology. In our ALD process the challenge of simultaneously incorporating phosphorus and nitrogen in the films is overcome by using a novel nitrogen-containing phosphorus precursor, diethyl phosphoramidate, together with lithium hexamethyldisilazide as the lithium precursor. A temperature window is found around 270–310 °C, where homogeneous films are realized and the film growth is controlled in a digital manner by the number of ALD cycles at a rate of ∼0.7 A/cycle. The process allows for a high N-to-P ratio in the films, which is beneficial for achieving the required high ionic conductivity. For a film deposited at 330 °C with a composition of Li0.95PO3.00N0.60 according to RBS/NRA analysis, an ionic conductivity value as high as 6.6 × 10–7 S cm–1 is measured at 25 °C.
