Boosted Na-MnO supercapacitor performance via strong metal support interaction.

MnO is widely utilized as an electrode material in supercapacitors. However, overcoming challenges such as sluggish ion migration, aggregate tendency, and low conductivity is imperative for optimizing MnO-based supercapacitors. Herein, NaMnO was employed as the Mn precursor to introducing a higher concentration of small Na ions into the layer structure of δ-MnO.

Scale-Up, Continuous and Low-Temperature Production of Multimetal Based Electrocatalysts toward Water Electrolysis.

Electrocatalytic water splitting is a crucial strategy for advancing hydrogen energy and addressing the global energy crisis. Despite its significance, the need for a straightforward and swift method to synthesize electrocatalysts with exceptional performance remains pressing. In this study, we demonstrate a novel approach for the preparation of multimetal-based electrocatalysts in a continuous flow reactor, enabling the quick synthesis of a large number of products through a streamlined process.

Reinforcing Cd-S bonds through morphology engineering for enhanced intrinsic photocatalytic stability of CdS.

Effectively mitigating photocorrosion is paramount for achieving high-efficiency and sustainable hydrogen production through photocatalytic water splitting over CdS. In this work, we develop a morphology engineering strategy with adjustable Cd-S bond energy through a simple chemical bath deposition method to synthesize novel hollow hemispherical CdS (H-CdS). The morphologic structure CdS can be precisely controlled by adjusting the reaction temperature, time and pH.

Photo-thermal Catalytic Hydrogenation of Halogenated Nitrobenzenes over Ni/P25 Catalyst.

As haloanilines (HANs) are important organic intermediates and fine chemicals, their preparation over non-noble-metal-based catalysts by catalytic hydrogenation has attracted wide attention. However, the reaction suffers from relatively harsh conditions. Herein, we found that a 3.

Understanding the Poly (Triazine Imide) Crystals Formation Process: The Conversion from Heptazine to Triazine.

Poly (triazine imide) (PTI) generally obtained via ionothermal synthesis features extended π-conjugation and enhanced crystallinity. However, in-depth investigation of the polycondensation process for PTI is an onerous task due to multiple influencing factors and limited characterization techniques. Herein, to simplify the polymerization route and exclude non-essential factors, PTI was prepared by calcining only melamine and LiCl.

The effect of doping and strain on superconductivity of T-graphene.

As an allotrope of graphene, T-graphene was predicted to be an intrinsic two-dimensional (2D) superconductor with a superconducting critical temperature () of about 20.8 K [Gu , Chin. Phys.

Diagnosis and Management of Giant Esophageal Fibrovascular Polyp With Hypopharyngeal Pedicle.

Fibrovascular polyps (FVPs) with hypopharyngeal pedicles (hFVPs) are the rare intraluminal benign tumours of the upper aerodigestive tract, and their accurate diagnosis and optimal management are challenging. The present retrospective study attempted to explore the optimal diagnosis and treatment of hFVPs. The clinical records of 2 patients with giant, irregularly shaped hFVPs, who underwent several failed surgical procedures after inaccurate diagnosis, were reviewed.

A nickel-iridium alloy as an efficient heterogeneous catalyst for hydrogenation of olefins.

Nickel and iridium supported on SiO2 (Ni-Ir/SiO2) acted as an effective and reusable heterogeneous catalyst for hydrogenation of olefins, and it showed higher activity and selectivity than the monometallic counterparts. The Ni-Ir/SiO2 catalyst has small Ni-Ir alloy and monometallic Ni particles, and the high catalytic performance can be attributed to the isolated Ni atom in the Ni-Ir alloys.
