RF Heating Effects in CEST NMR with Hyperpolarized 129Xe Considering Different Spin Exchange Kinetics and Saturation Schemes

ChemPhysChem, EarlyView.
Chemical exchange saturation transfer (CEST) with different spin exchange kinetics can require substantial RF energy deposition to label magnetization in separate chemical environments. The parameter space with optimum saturation should be judged not only concerning unwanted heating but also consider efficient CEST build‐up (depolarization rate ...

Nickel‐Based Cocatalysts on Titanium‐Doped Hematite Empower Direct Photoelectrochemical Valorisation of 5‐Hydroxymethylfurfural

ChemSusChem, EarlyView.
Nickel modified titanium doped hematite photoanode shows a selective hole scavenging for the photoelectrochemical valorisation of the biomass derivative HMF to FDCA, overcoming the competition with water oxidation. Insights on the role of nickel in the HMF oxidation process are achieved with operando x‐ray absorption spectroscopy via element‐selective ...

A Survey of Phase Shifters for Microwave Phased Array Systems

International Journal of Circuit Theory and Applications, EarlyView.
ABSTRACT Phased Array Systems (PASs) are extensively used in radar and telecommunication systems for diverse applications, including military surveillance and wireless broadband communication. Besides, they are becoming increasingly indispensable in modern applications such as multi‐function phased array radars for weather monitoring and aircraft ...

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Multiple Hydrogen‐Bond Cross‐Linking Solid–Solid Phase Change Materials for Batteries’ Thermal Management

EcoEnergy, EarlyView.
Multiple hydrogen‐bond cross‐linking solid–solid phase change materials. ABSTRACT Solid–solid phase change materials usually suffer from the challenges of low thermal storage capacity and poor mechanical strength in thermal management applications. Additionally, solid–solid phase change materials are often prepared by a chemical cross‐linking strategy,
