Gap-Size-Dependent Effective Phase Transition in Metasurfaces of Closed-Ring Resonators

open access: yesCrystals, 2021
We theoretically investigate a metal-to-insulator transition in artificial two-dimensional (2D) crystals (i.e., metasurfaces) of tightly coupled closed-ring resonators.

Effects of gap size and within-gap position on seedlings establishment in silver fir stands

open access: yesiForest - Biogeosciences and Forestry, 2008
The conversion of pure conifer plantations into stands with heterogeneous structure and composition is a current silvicultural challenge in Italy. A silvicultural system aiming to the regeneration of natural forests by means of openings in the canopy ...

Effect of Gap Size on The Dynamic of Micro Environments dring the Daytime at Castanopsis kawakamii Natural Reserve Forest, Sanming City, China [PDF]

open access: yesEnvironment and Natural Resources Journal, 2016
The temporal dynamics of micro-environments within gap size affect the species regeneration. This study aimed to determine the effects of gap size on the variation of micro-environments during the daytime.

Impacts of the gap size between two bluff bodies on the flow field within the gap [PDF]

open access: yes, 2017
When two bluff bodies is in close tandem, i.e, the distance between blocks D is less than half of the height of the body H, the flow field is very similar to that in the gap between tractor and trailer in a truck, and hence understanding such a flow ...

Qualitative and quantitative evaluation of natural regeneration in gaps within beech (Fagus orientalis Lipsky) stands of Caspian Region [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2005
According to few recent studies, regeneration was favourably established in few natural gaps at beech stands located in Golband Forest of Caspian region of Iran (Jamand district), whereas in other gaps, weeds including Rubus sp.

Size-Dependent Band-Gap and Molar Absorption Coefficients of Colloidal CuInS2 Quantum Dots

open access: yes, 2018
The knowledge of the quantum dot (QD) concentration in a colloidal suspension and the quantitative understanding of the size-dependence of the band gap of QDs are of crucial importance from both applied and fundamental viewpoints.

Role of crevice size induced microenvironment variation within the gap in initiating crevice corrosion of 201 stainless steel

open access: yesFrontiers in Materials
The effects of the real-time changes in the microenvironment within the crevice caused by the change in crevice size on the induction of crevice corrosion of 201 stainless steel (201-SS) in 1 M (pH = 4.00) NaCl solution were evaluated using conventional ...

Primary cultures of chick osteocytes retain functional gap junctions between osteocytes and between osteocytes and osteoblasts

open access: yes, 2008
The inaccessibility of osteocytes due to their embedment in the calcified bone matrix in vivo has precluded direct demonstration that osteocytes use gap junctions as a means of intercellular communication.

Gap size effects on tree regeneration in afforestations of Black pine (Pinus nigra Arn.)

open access: yesForest@, 2009
The authors deal with the problem of the re-naturalization of afforestations of Black pine in the Apennines (Central Italy). Gap-cutting of two different sizes (the gap diameter/stand height ratios were respectively 0.75 and 1.0) on age classes stands ...

Size-Dependent Spinodal and Miscibility Gaps for Intercalation in Nanoparticles [PDF]

open access: yesNano Letters, 2009
Using a recently-proposed mathematical model for intercalation dynamics in phase-separating materials [Singh, Ceder, Bazant, Electrochimica Acta 53, 7599 (2008)], we show that the spinodal and miscibility gaps generally shrink as the host particle size decreases to the nano-scale.
