Solidly mounted resonators aging under harsh environmental conditions

Trapped hybrid modes in solidly mounted resonators based on c-axis oriented hexagonal crystals

Graphene as an active virtually massless top electrode for RF solidly mounted bulk acoustic wave (SMR-BAW) resonators.

Mechanical and electrical losses induced by an electrode material greatly influence the performance of bulk acoustic wave (BAW) resonators. Graphene as a conducting and virtually massless 2D material is a suitable candidate as an alternative electrode material for BAW resonators which reduces electrode induced mechanical losses. In this publication we show that graphene acts as an active top el...

Adsorption of a Protein Monolayer via Hydrophobic Interactions Prevents Nanoparticle Aggregation under Harsh Environmental Conditions.

We find that citrate-stabilized gold nanoparticles aggregate and precipitate in saline solutions below the NaCl concentration of many bodily fluids and blood plasma. Our experiments indicate that this is due to complexation of the citrate anions with Na+ cations in solution. A dramatically enhanced colloidal stability is achieved when bovine serum albumin is adsorbed to the gold nanoparticle su...

Goat Production under Harsh Environmental Conditions: the Physiological Basis and the Challenge

Goats living in harsh environments represent a climax in the capacity of domestic ruminants to adjust to such areas. This ability is multifactorial. Low body mass and low metabolic requirements of goats can be regarded as important assets in minimising their maintenance and water requirements in areas where water sources are widely distributed and food sources are limited by their quantity and ...

A Suitability Map for Keeping Honey Bees Under Harsh Environmental Conditions Using Geographical Information System

Abstarct: Heat stress becomes a problem in different parts of the world and recently was considered as a threat to apiculture. Many countries suffer from extreme heat during certain periods of the year. There is a great diversity in the weather of Saudi Arabia throughout the year but the most extreme conditions occur during the summer season, when apiculture copes with extreme heat. Not all reg...
