Low Temperature MOCVD-Processed Alumina Coatings [PDF]
, 2006 We first present a Review about the preparation of alumina as thin films by the technique of MOCVD at low temperature (550°C and below). Then we present our results about thin films prepared by the low pressure MOCVD technique, using aluminium tri ...

Agrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.Abstract Locust outbreaks worldwide frequently impact vast regions and millions of people. Effective mapping and monitoring of locust habitats, along with accurate outbreak prediction, are crucial for minimizing damage to crops and pasturelands. Gursum experienced its most severe desert locust infestation in 25 years during 2019 and 2020, resulting in ...

Ecosphere, Volume 16, Issue 9, September 2025.Abstract Volcanic ash is widely held responsible for fertilizing soils, but the processes and conditions leading to volcanic soil fertility remain poorly understood. We report here the results of a greenhouse volcanic ash fertilization (VAF) experiment aimed to explore the impact of basaltic ash addition (0–10 wt%) to soil on plant growth, nutrient ...
