“…With this study, the authors also discussed the reasons for the selection of hexagonal packing instead of other packing kinds and attributed this behavior to its having the lowest free energy. 151 Peng et al also examined the various factors influencing the pore formation process and hole sizes such as polymer molecular weight, solvent properties, and humidity to gain a better understanding of the pore formation mechanism. 152 PS having different molecular weights and toluene, chloroform, carbon disulfide, and tetrahydrofuran solvents were studied.…”

Seven different nonlinear height (h)-diameter (d) models were developed and compared for brutian pine (Pinus brutia Ten.), black pine (Pinus nigra Arnold), and Taurus cedar (Cedrus libani A.Rich.) in southern Turkey. Residual analysis was conducted to identify the error structure. A weighting factor of w i =1/d was found to be appropriate for achieving the equal error variance assumption. The performance of the models was compared and evaluated based on 6 statistical criteria and residual analysis. Results suggested that the Gompertz model was superior to the other models in terms of its predictive ability. These tree species were located throughout the Mediterranean region, covering a wide range of topographic and climatic conditions. It is well known that height-diameter relationships depend heavily on local environmental conditions. Differences in the height-diameter relationship among and between ecoregions were tested using the nonlinear extra sum of squares method. Test results suggested that height-diameter models significantly differed between ecoregions, indicating that ecoregion-based height-diameter models are needed for prediction purposes. The ecoregion-based height-diameter models developed in this study may provide more accurate information for developing forest growth and yield models.

“…The first report of breath figures films was based on polystyrene [31], then others polymeric structures have been progressively used to introduce physical properties or more advanced characteristics to the whole film such as optical grade poly (methyl methacrylate) [149], flexible polydimethylsiloxane [150], biocompatible and biodegradable polycaprolactone [73], thermally stable polyimide [151], or even conjugated polymers [152] with electronic and optical properties useful for solar and optoelectronic devices. …”

The creation of porous polymer surfaces is a center of interest in current research. Porous surfaces possess extremely high specific surface areas, thus allowing their employment in a large variety of applications including electronics, photonics or biotechnology [1,2]. Pore size and distribution can play a major role in selective transportation or in insulation processes amongst others [3]. Those porous materials with cavities in the micrometer size range are interesting in catalysis, sensors, membrane preparation or as scaffolds for composite materials. Moreover porous materials with pore dimensions comparable to the wavelength of visible light are of interest as photonic band-gaps and optical stop-bands.Structures with micrometer or submicrometer dimensions can be created using different templating methods [4,5]. A large variety of approaches have been developed and employed to prepare microporous structured materials, including the use of templates such as ordered arrays of colloidal particles to produce inverse opal structures [6][7][8][9], from transformed polymeric sphere arrays [10,11], using emulsion droplets as templates [12], employing natural biological templates [13][14][15][16], by

“…However, this still requires expensive lithography devices. [1] As an alternative route, template-induced lithography using self-organized colloidal particles, [2] block copolymers, [3] emulsions, [4] and selfassembled monolayered molecules [5] has been developed for simple and cheap nanometer-scale pattern formation. Colloidal lithography (CL) uses self-assembled arrays of colloidal particles as sacrificial masks, and various functional materials are deposited through the interstitial pores between the particles.…”

Multiscale nanopatterns fabricated by colloidal lithography, using two‐dimensional self‐assemblies of photoresist particles as masks, are presented. The colloidal masks with features of multiple length scales are obtained by photolithography and used for constructing submicrometer‐hole arrays over large areas (see Figure). By depositing functional materials through these masks, nanopatterned substrates useful in a wide range of applications can be produced.
