Advanced Functional Materials, EarlyView.The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Laser‐Assisted Phase Engineering of 2D MoS2 for Efficient Solution‐Processed Electronics
Advanced Materials, EarlyView.Here, local laser‐assisted phase transition from solution‐processed phase‐pure 1T′ to 2H MoS2 is shown to critically depend on the irradiation atmosphere. While processing in air leads to damaged insulating regions, inert conditions yield semiconducting 2H domains, enabling direct field‐effect transistor patterning with optimized lateral 1T′‐2H MoS2 ...

Advanced Science, EarlyView.A time‐multiplexed nanobody‐functionalized organic electrochemical transistor enables rapid and sensitive detection of three respiratory viral proteins from saliva. Sequentially addressed multi‐gate electrodes on a shared channel achieve around 1 fm detection within 15 min without sample preprocessing. Clinical validation demonstrates high specificity,

Advanced Science, EarlyView.This study introduces a dual‐regulation strategy utilizing a Mn‐doped Co3O4 support to enhance the activity and stability of low‐loading IrO2 catalysts for acidic water oxidation. Mn induces strong Mn─O covalency to reinforce the spinel lattice and activates Ir sites via interfacial electron transfer.

, 2014 Why do young Saudis, night after night, joyride and skid cars on Riyadh's avenues? Who are these 'drifters' who defy public order and private property? What drives their revolt? Based on four years of fieldwork in Riyadh, Pascal Menoret's Joyriding in Riyadh explores the social fabric of the city and connects it to Saudi Arabia's recent history.

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity
Advanced Science, EarlyView.In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

Childhood Bacterial Meningitis in Riyadh
Annals of Saudi Medicine, 1991 One hundred and six patients with culture-positive bacterial meningitis were admitted to Sulemania Children's Hospital, Riyadh, from February 1985 to July 1990. The most common organisms causing meningitis in children older than 1 month were Hemophilus influenzae type b (N = 61), Streptococcus pneumoniae (N = 19), and Neisseria meningitidis (N = 14 ...
