Unilateral Sacroiliac Hemiagenesis in a Young Woman Presenting With Chronic Mechanical Low Back and Buttock Pain: A Case Report

Sacral agenesis is a rare congenital malformation belonging to the spectrum of caudal regression syndrome, whose clinical manifestations are highly variable and depend on the phenotype of the disease.We report the case of a young woman who presented with chronic mechanical low ba...

Anion-Activated Supramolecular Proton Relays Enable Neutral-pH and Seawater Oxidation

Abstract Neutral-pH and direct seawater oxidation are critically hindered by sluggish proton-coupled electron transfer (PCET) and competitive chloride corrosion. Here, we employ surface-confined azacrown macrocycles of varying nitrogen content as supramolecular proton-management...

Oxygen-Vacancy-Controlled Band-Gap Engineering in Fe/Co Co-doped La-Modified Bismuth Titanate: Integrated Experimental and First-Principles Analysis

Abstract Layered Aurivillius ferroelectrics offer a route to multifunctional band-gap engineering, yet the role of oxygen vacancies in band-edge reconstruction in Fe/Co-modified compositions remains poorly resolved. Here, oxygen annealing of Bi3.25La0.75Ti2.60(Fe0.50,Co0.50)0.40O...

Development and Field Validation of WaziSense, a Low-Cost Solar-Powered IoT Smart Tensiometer for Soil–Water Monitoring and Irrigation Scheduling in Semi-Arid Agriculture

Water scarcity in semi-arid regions makes efficient irrigation scheduling a priority, yet farm-level adoption of soil-moisture monitoring remains limited by the cost, low portability and installation complexity of commercial sensing systems. This study presents the development an...
