DETERMINATION OF HLB VALUES OF SOME NONIONIC SURFACTANTS AND THEIR MIXTURES

Studia Universitatis Babes-Bolyai Chemia, 2017
Advanced analytical and impact assessment methods are needed for the development of modern surfactants, so the composition, the effect and other properties of surfactants are examined by analytical tools which may be suitable for the quality testing of ...

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Measurement of Thermal Conductivity and Saturation of Gas Hydrates in Sediment by Thermal Pulse Probe-Time Domain Reflection Technique

Yankuang ceshi, 2013
So far, gas hydrates not only have been explored in marine and frozen areas of China, but also have been sampled successfully. The thermal conductivity of sediments with gas hydrates is a key parameter for estimating the resource and designing a proper ...

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Intranasal delivery of bryostatin-1 using surface charge-engineered lipid nanoparticles to modulate mucosal defense for allergic rhinitis treatment

Scientific Reports
Allergic rhinitis (AR), driven by immune imbalance and excessive IgE production, manifests with symptoms that significantly impair the patient’s quality of life. Current therapies mainly provide symptomatic relief without correcting the underlying immune

LSTM-Autoencoder Deep Learning Model for Anomaly Detection in Electric Motor

Energies
Anomaly detection is the process of detecting unusual or unforeseen patterns or events in data. Many factors, such as malfunctioning hardware, malevolent activities, or modifications to the data’s underlying distribution, might cause anomalies.

Chaos Theory: Implications for Cost Overrun Research in Hydrocarbon Megaprojects [PDF]

, 2016
Cost overruns are a recurrent problem in hydrocarbon (oil and gas) megaprojects. An understanding of why and how they occur is needed if they are to be mitigated; such knowledge can provide managers with the foundations to develop techniques to reduce ...

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,
