Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Rhinoplasty in the Black Sea Region

Journal of Craniofacial Surgery, 2012
We have retrospectively evaluated the charts of 120 patients who had undergone rhinoplasties. The noses were divided into 2 types. Type 1 (42 cases) was characterized by a normal radix, high dorsum, and prominent vault. These noses were corrected by dorsal reduction, lateral osteotomy when needed, and caudal septal resection.

The geopolitics of the black sea region

Southeast European and Black Sea Studies, 2001
The fate of populations living around the Black Sea is related to the crossroads situation, to political fragmentation and to the struggle of outside powers for zones of influence. Those elements have been combined in different ways; times of stability and prosperity have been succeeded by periods of war and destruction and vice versa.

Is the Black Sea a Region?

2016
At one point in the Histories, Herodotus describes what it is like to be at the mouth of the Bosphorus gazing out over the tumultuous expanse of the Black Sea. He stands at the top of the Clashing Rocks, the two large boulders that guard the entrance to the sea, known even long before his time for their role in nearly ending Jason’s quest for the ...

An Overview of the Environmental Issues in the Black Sea Region

1997
Bulgaria, Georgia, Rumania, the Russian Federation, Turkey and Ukraine share a common heritage, namely the Black Sea, which has been a centerpoint for many civilizations. This sea has served each of these countries as a backbone in their economies, but has at the same time been used as a waste receptacle by them.

Mountainous Vegetation of Central Black Sea Region

2015
Central Black Sea Region includes many different vegetation types. At high elevations, forest vegetation is dominant. Some forest types have closed canopies, while some of them can be disturbed mainly due to anthropogenic factors (grazing, clear-cutting, etc.).

Theoretical Approaches to the Black Sea Region: ‘Is the Wider Black Sea Area a Region?’

2020
The paper aims to shed light on how a region may be built out of the Black Sea area. Therefore, the paper asks, first, whether the Black Sea area is a region or a region-to-be. If neither, then how to transform the Black Sea area into a region through the context of ‘new regionalism’ and the relevant theories.
