Can venture capital shareholding improve M&A performance? An empirical study based on Chinese GEM-listed companies.

Existing studies have explored the impact of venture capital shareholding on the GEM-listed companies before and after listing from multiple perspectives. However, there has been limited research on the influence of venture capital shareholding on these companies' mergers and acquisitions(M&A) activities and performance. Additionally, two conflicting research findings have been presented in limited relevant studies.

KF-Containing Interphase Formation Enables Better Potassium Ion Storage Capability.

Rechargeable potassium ion batteries have long been regarded as one alternative to conventional lithium ion batteries because of their resource sustainability and cost advantages. However, the compatibility between anodes and electrolytes remains to be resolved, impeding their commercial adoption. In this work, the K-ion storage properties of Bi nanoparticles encapsulated in N-doped carbon nanocomposites have been examined in two typical electrolyte solutions, which show a significant effect on potassium insertion/removal processes.

Electromagnetic-acoustic splitter with a tunable splitting ratio based on copper plates.

Acoustic splitters and electromagnetic splitters can be applied in various fields (e.g., navigation and interference detection).

Active Thermal Metasurfaces for Remote Heating/Cooling by Mimicking Negative Thermal Conductivity.

Remote temperature control can be obtained by a long-focus thermal lens that can focus heat fluxes into a spot far from the back surface of the lens and create a virtual thermal source/sink in the background material, around which the temperature field distribution can be remotely controlled by varying the parameters of the thermal lens. However, because of the lack of negative thermal conductivity, existing thermal lenses have extremely short focal lengths and cannot be used to remotely control the temperature field around the virtual thermal source/sink. In this study, a general approach is proposed to equivalently realize materials with negative thermal conductivity using elaborately distributed active thermal metasurfaces (ATMSs).

Promotion of Activated Carbon on the Nucleation and Growth Kinetics of Methane Hydrates.

Due to the hybrid effect of physical adsorption and hydration, methane storage capacity in pre-adsorbed water-activated carbon (PW-AC) under hydrate favorable conditions is impressive, and fast nucleation and growth kinetics are also anticipated. Those fantastic natures suggest the PW-AC-based hydrates to be a promising alternative for methane storage and transportation. However, hydrate formation refers to multiscale processes, the nucleation kinetics at molecule scale give rise to macrohydrate formation, and the presence of activated carbon (AC) causes this to be more complicated.

Tissue compliance meter is a more reproducible method of measuring radiation-induced fibrosis than late effects of normal tissue-subjective objective management analytical in patients treated with intracavitary brachytherapy accelerated partial breast irradiation: results of a prospective trial.

Identification of radiation-induced fibrosis (RIF) remains a challenge with Late Effects of Normal Tissue-Subjective Objective Management Analytical (LENT-SOMA). Tissue compliance meter (TCM), a non-invasive applicator, may render a more reproducible tool for measuring RIF. In this study, we prospectively quantify RIF after intracavitary brachytherapy (IB) accelerated partial breast irradiation (APBI) with TCM and compare it with LENT-SOMA.

Synthesis of urchin-like VO2 nanostructures composed of radially aligned nanobelts and their disassembly.

Urchin-like VO(2)(B) nanostructures composed of radially aligned nanobelts have been synthesized by the homogeneous reduction reaction between peroxovanadic acid and oxalic acid under hydrothermal conditions. The influences of synthetic parameters, such as reaction times and the concentration of oxalic acid, on the morphologies and crystals of the resulting products have been investigated. The formation of VO(2)(B) nanostructures undergoes a reduction-dehydration phase-transition and disassembly process.

Low-valent vanadium oxide nanostructures with controlled crystal structures and morphologies.

Low-valent vanadium oxide nanostructures have been synthesized in large quantities using commercial V2O5 powder as the precursor by a facile reduction method. The crystal structures and morphologies of vanadium oxide nanostructures can be adjusted by altering the concentrations and types of reductants. VO2(B) nanostructures are fabricated using oxalic acid as the reductant.
