Summary: Carbon materials are commonly used as supporting substrates for electrocatalysis due to their high conductivity and chemical inertness. Understanding and preventing corrosion are crucial for long-lasting electrocatalysis. Real-time monitoring of CO2 evolution by DEMS provides valuable information about carbon corrosion, and using CO as a corrosion marker allows successful monitoring of corrosion in both acidic and alkaline media. Corrosion in alkaline media is qualitatively similar to that in acidic media but is quantitatively alleviated.

Summary: Imaging the infant brain with MRI has improved our understanding of early neurodevelopment. However, head motion during MRI acquisition is detrimental to both functional and structural MRI scan quality. Providing MRI technicians with real-time motion estimates via FIRMM software can help obtain high-quality, low motion fMRI data in infants. The addition of FIRMM significantly increased the amount of usable fMRI data acquired per infant, demonstrating its value for research and clinical infant neuroimaging.

Summary: H-1-fMRS in the human brain is a valuable technique to evaluate and quantify metabolic responses to localized brain activity, providing insights into brain functioning and connectivity. Understanding healthy brain metabolism during tasks is crucial for detecting and characterizing neurochemical changes associated with neurological disorders, while new techniques like optogenetics may offer more specificity in investigating brain cell populations and molecular changes.

Summary: The development of flexible and stretchable electronics has revolutionized biosensor techniques for probing biological systems. Flexible and stretchable electrochemical sensors (FSECSs) enable the in situ quantification of biochemical molecules in different biological entities due to their exceptional sensitivity, fast response, and easy miniaturization. This review discusses the key developments in electrode fabrication and FSECSs functionalization, as well as their applications in exploring the chemical information from different biological entities. Current challenges and future opportunities for FSECSs are also highlighted.

Summary: By using ultrasound to activate specific neurons in the hypothalamus, researchers have successfully induced a torpor-like state in rodents, characterized by hypothermia and reduced metabolic rate. This noninvasive technique involves closed-loop feedback control of ultrasound stimulation and automated detection of body temperature. The study identifies TRPM2 as an ultrasound-sensitive ion channel in the hypothalamus preoptic area, and demonstrates the feasibility of ultrasound-induced hypothermia and hypometabolism in non-torpid animals.

Summary: OptoNet II is an advanced MATLAB toolbox developed to efficiently analyze brain connectivity and overcome the limitations of its predecessor. Through a finger-tapping task experiment, it effectively demonstrates the impact of tDCS on functional brain region connectivity.

Summary: Ischemic stroke causes abrupt neurologic deficits and little is known about early hemodynamic changes in the brain. This study used functional ultrasound imaging to monitor relative cerebral blood volume (rCBV) variations after stroke onset in rats. Two stroke models were compared and a typical hemodynamic pattern was observed, with a drop in rCBV followed by reperfusion of nearby brain regions. The severity and location of the ischemia varied within the groups, with infarcts extending to non-ischemic regions associated with spreading depolarizations.

Summary: A highly sensitive respirometric method is developed for real-time monitoring of reaction rates involving H-2 and O-2 during electrochemical polarization. The method allows quantification of rates resulting from reactions such as HER, ORR, and OER based on simultaneous monitoring of total pressure and O-2 partial pressure changes. It enables deconvolution of net electric current into cathodic and anodic partial reaction rates and determination of the true metal oxidation rate. The respirometric monitoring approach also distinguishes the rate of O-2 evolution from electrode oxidation processes.

Summary: Exploring and developing multifunctional intelligent biomaterials is crucial for improving next-generation therapies in tissue engineering and regenerative medicine. These biomaterials can mimic the in situ microenvironment and provide specialized bioactive signals to regulate the surrounding biological habitat, contributing to wound healing and biomaterial integration. The connection between stem cells and biomaterials can stimulate specific modifications in cell properties and fate, influencing processes such as self-renewal, adhesion, and differentiation.

Summary: Clinical studies have shown that the timing of decline in regional cerebral oxygen saturation (rSO(2)) after cardiac arrest and cardiopulmonary resuscitation can predict neurological outcomes. This study investigated the relationship between the timing of rSO(2) decline and brain injury severity in a rat model of cardiac arrest. The results suggest that the timing of rSO(2) decline can serve as a predictor of good neurological outcomes after cardiac arrest and cardiopulmonary resuscitation.

Summary: By investigating the topology of neuronal co-activity in the mouse hippocampus network, researchers found that high-activity principal cells form the core of memories, while low-activity cells join co-activity motifs across different operational axes. This organizational principle reveals continuous integration and interaction of hippocampal memories. Gava et al. explore how new associative memories integrate into the network and restructure neural patterns representing prior memories from a graph theoretical perspective.

Summary: This study proposes a multi-penalized state-space model for analyzing unobserved dynamics, using a data-driven regularization method. Novel algorithms are developed to solve the model, and a cross-validation method is introduced to evaluate regularization parameters. The effectiveness of this method is validated through simulations and real data analysis, enabling a more accurate exploration of cognitive brain functions.
