AI Article Synopsis
- - Researchers developed a new hybrid catalyst called NiLDH@YZ, which combines nickel-layered double hydroxide with Y-zeolite, to enhance Glaser homocoupling reactions through mechanochemical agitation.
- - The study measured the properties of the catalyst, such as surface area, porosity, and acid-base characteristics, showing it has strong acid-base bifunctionality.
- - The best performance was achieved with a specific hybrid (0.5NiLDH@0.5YZ), yielding 83% after 60 minutes of agitation, and it maintained effectiveness across four catalytic cycles, indicating its potential in carbon-carbon bond formation using a new approach that blends mechanochemistry with traditional catalysis.
Article Abstract
Herein, we report the synthesis of nickel-layered double hydroxide amalgamated Y-zeolite (NiLDH@YZ) hybrids and the evaluation of the synergistic effect of various NiLDH@YZ catalysts and mechanochemical agitation on Glaser homocoupling reactions. Nitrogen adsorption-desorption experiments were carried out to estimate the surface area and porosity of NiLDH@YZ hybrids. The basicity and acidity of these hybrids were determined by CO -TPD and NH -TPD experiments respectively and this portrayed good acid-base bifunctional feature of the catalysts. The NiLDH@YZ-catalyzed mechanochemical Glaser coupling reaction achieved best yield of 83 % for the 0.5NiLDH@0.5YZ hybrid after 60 min of agitation, which revealed the highest acid-base bifunctional feature compared to all the investigated catalysts. The developed catalyst has proven itself as a robust and effective candidate that can successfully be employed up to four catalytic cycles without significant loss in catalytic activity, under optimized reaction conditions. This work demonstrated a new strategy for C-C bond formation enabled by the synergy between mechanochemistry and heterogeneous catalysis.

Background: The collection of substantial amounts of electroencephalogram (EEG) data is typically time-consuming and labor-intensive, which adversely impacts the development of decoding models with strong generalizability, particularly when the available data is limited. Utilizing sufficient EEG data from other subjects to aid in modeling the target subject presents a potential solution, commonly referred to as domain adaptation. Most current domain adaptation techniques for EEG decoding primarily focus on learning shared feature representations through domain alignment strategies.

Sensors are indispensable tools of modern life that are ubiquitously used in diverse settings ranging from smartphones and autonomous vehicles to the healthcare industry and space technology. By interfacing multiple sensors that collectively interact with the signal to be measured, one can go beyond the signal-to-noise ratios (SNR) attainable by the individual constituting elements. Such techniques have also been implemented in the quantum regime, where a linear increase in the SNR has been achieved via using entangled states.

Introduction: Breaking the chain of transmission of an infectious disease pathogen is a major public health priority. The challenges of understanding, describing and predicting the transmission dynamics of infections have led to a wide range of mathematical, statistical and biological research problems. Advances in diagnostic laboratory procedures with the ability to test multiple pathogens simultaneously mean that co-infections are increasingly being detected, yet little is known about the impact of co-infections in shaping the course of an infection, infectivity, and pathogen replication rate.

Background/aim: Ifosfamide is used clinically with doxorubicin as first-line chemotherapy for soft-tissue sarcoma. However, ifosfamide efficacy for soft-tissue sarcoma is limited due to frequent occurence of ifosfamide resistance and thus more effective therapy is needed. The present study aimed to determine the synergy of recombinant methioninase (rMETase) plus ifosfamide against HT1080 human fibrosarcoma cells in vitro.
