Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$

Do Brain Extracellular Fluid Concentrations Predict PET‐Inferred Receptor Occupancy in Human CNS? A Mechanistic Model‐Based Analysis of Dopamine D2 Receptor Ligands

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
A mechanistic CNS PBPK model framework was applied to eight antipsychotic D2 receptor ligands, comparing brain extracellular fluid (brainECF) and brain cell membrane (brainM) as biophase for predicting human receptor occupancy compared against PET neuroimaging data. BrainM concentrations showed improved agreement with PET‐derived receptor occupancy for

A Co‐Designed Implicit‐Reset Path PFD and Current Mismatch Compensated CP Enabling Sub‐0.5% Mismatch and Dead Zone‐Free for Low‐Spur PLLs

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A co‐designed implicit‐reset phase‐frequency detector (PFD) and nonlinear amplifier‐assisted charge pump (CP) achieve dead zone‐free operation from 10 MHz to 4.7 GHz with < 0.5% current mismatch without calibration, enabling −80 dBc of reference spur and 0.50 ps of RMS jitter in a 180 nm of CMOS PLL.

Near‐Infrared Light‐Driven Photocatalysis: From Advanced Light‐Harvesting Architectures to Rational Reactor Design

open access: yesEcoEnergy, EarlyView.
This review systematically elucidates the regulatory strategies for NIR light, encompassing macroscopic mechanisms such as band engineering, localized surface plasmon resonance (LSPR), upconversion luminescence, and photosensitizer molecules. Furthermore, it provides an in‐depth discussion on their cutting‐edge applications in energy conversion (e.g ...
