Supra-ceramics: a molecule-driven frontier of inorganic materials.

Discoveries and technological innovations over the past decade are transforming our understanding of the properties of ceramics, such as 'hard', 'brittle', and 'homogeneous'. For example, inorganic crystals containing molecular anions exhibit excellent secondary battery characteristics, and the fusion of inorganic solids and molecules results in innovative catalytic functions and physical properties. Different from the conventional ceramics such as metal oxides that are formed by monatomic cations and anions, unique properties and functions can be expected in molecular-incorporated inorganic solids, due to the asymmetric and dynamic properties brought about by the constituent molecular units.

Catalytic partial oxidation of methane over oxide-ion-conductive lanthanum silicate apatites.

A lanthanum silicate LaSiO (LSO) crystallizes in an apatite-type structure and has been known as a promising oxide-ion conductor. Here, we report the activity of LSO for catalytic partial oxidation of methane (CPOX) to synthesis gas. The LSO catalyst demonstrated relatively high catalytic activity from 500 to 700 °C, with CH conversion reaching 22.

The Utility and Feasibility of Laparoscopic Surgery in Patients Diagnosed With Cervical Cystic Lesions.

Introduction: This observation study aimed to differentiate between lobular endocervical glandular hyperplasia (LEGH) and gastric-type mucinous carcinoma (GAS) while evaluating the feasibility and efficacy of laparoscopic surgery in the preoperative diagnosis of cervical cystic lesions.

Method And Material: A retrospective study was conducted to evaluate the diagnostic process and laparoscopic surgical management of cervical cystic lesions suspected to be LEGH or GAS. Preoperatively and postoperatively, MRI, cytology, histology, tumor marker analysis, and surgical outcomes (blood loss during surgery, operative time) were assessed.

Renal Impairment of Proximal Tubular Injury Caused by Red Yeast Rice Supplement: Report of 2 Cases.

Introduction: Drug-induced tubulointerstitial injury is a common cause of renal impairment. Since the mechanisms of drug-induced tubular injury are diverse, various treatment approaches are needed according to the pathogenesis. Renal biopsy is indispensable to determine not only the pathological diagnosis, but also the underlying mechanism, and to guide appropriate treatment.

Mechanistic Insights on the Formation of a Carbodiimide Ion from Urea in LaONCN Synthesis Based on the "Proanion" Strategy.

This study affords mechanistic insights into the formation mechanism of carbodiimide ions (NCN) from urea during the synthesis of LaONCN by employing the "proanion" strategy without using NH gas. It is a safer, cost-effective, and environmentally friendly approach. Urea, acting as a proanion, decomposes upon heating, facilitating conversion to NCN.
