Abstract Epitaxial growth is of significant importance over the past decades, given it has been the key process of modern technology for delivering high-quality thin films. For conventional heteroepitaxy, the selection of proper single crystal substrates not only facilitates the integration of different materials but also fulfills interface and strain engineering upon a wide spectrum of functionalities. Nevertheless, the lattice structures, regularity and crystalline orientation are determined once a specific substrate is chosen. In this work, we reveal the growth of twisted oxide lateral homostructures with multiple conjunction degree of freedom. The twisted lateral homostructures with atomically sharp interfaces can be composed of epitaxial “blocks” with different crystalline orientations, ferroic orders and phases. We further demonstrate that this approach is universal for fabricating various complex systems. Our results establish an efficient pathway towards twisted lateral homostructures, allowing epitaxial films to be arbitrarily tailored at designated positions with unbounded in-plane conjunction tunability.

The purpose of this paper was to isolate halophiles from Letea saline lake and to performed a screening for industrially relevant extracellular enzymes. The investigations were conducted from October 2016 until May 2018. After a random selection of colonies that grew on the medium culture, 82 isolates were investigated. Based on their salt requirements and tolerance, it was remarked the presence of isolates belonging to halotolerant and moderate halophilic bacteria. Morphological and biochemical tests were used to characterize them. The ability of the tested isolates to produce extracellular enzymes was evaluated on the culture medium with salinity varying between 0-4M and supplemented with a specific substrate. The highest hydrolytic activities were recorded for casein at 0M NaCl, 1M NaCl, 2M NaCl, and Tween 80 and inulin at 0M NaCl, 1M NaCl, 2M NaCl, and 3M NaCl.

The nature of organic energy reserves, and their relation to the microbial selection in activated sludge were of interest. The cellular carbohydrate and PHB were first examined in relation to their accumulation and degradation with activated sludge cultivated on glucose under batch and continuous feeding conditions. Then, CH accumulation was related with substrate uptake rate using activated sludge bearing different amounts of storage materials for both sludge. The cellular carbohydrate and PHB were of prime importance with both activated sludge. However, cellular carbohydrate was accumulated and decomposed more readily compared with PHB. The accumulation of cellular carbohydrate retarded its synthesis as well as glucose uptake. While no such relation was observed with PHB. The cellular carbohydrate accumulation capacity and attainable maximum specific substrate uptake rate were far greater for the batch-wise-fed activated sludge. Thus, the ability to accumulate cellular carbohydrate was found to be a prime selective advantage for floc formers in batch-wise-fed activated sludge. On the other hand, a sudden drastic stimulation of Sphaerotilusnatans in the continuously-fed activated sludge could not be well explained even though aided with Chudoba's kinetic selection theory.
