#surface
- Geological ablation — A conceptual form or terminological variant of 'ablație', used in classical geomorphology to describe the phenomenon of removal, washing away, or baring of rocks under the action of external agents (wind, flowing waters, waves). In soil dynamics, the term emphasizes the initial transport phase of fine detrital materials before they are deposited in sedimentary basins.
- Jointer planer — (Technical, jargon) A woodworking machine used for straightening and planing flat surfaces of timber; an industrial jointer planer equipped with a rotating cutterhead and adjustable tables.
- Hollow — A hollow place, concavity, small depression, or indentation formed naturally or artificially on a surface, in a terrain, on a rocky wall, or on an object. In geomorphology, the term describes a micro-landform created through the erosive action of water or soil compaction.
- Hollow-filled — Featuring many hollows, structural irregularities, or pronounced cavities; a terrain, path, or physical environment full of deep pits, valleys, or successive depressions. In a stylistic or regional sense, the term describes a geomorphologically fragmented surface that hinders movement and naturally collects runoff water.
- Adaxial — Facing toward the axis, located in the direction of the axis, or oriented toward the upper surface of a plant organ (such as the upper or inner surface of a leaf, situated closest to the plant stem). In botanical morphology, the term describes the structural polarity of organs during their developmental phase, being the opposite of 'abaxial'.
- Adhesive — Spelling variant or secondary technical form for the word 'adeziv' (adhesive). As a noun, it designates a substance capable of structurally fixing or bonding two surfaces through direct contact and molecular attraction. As an adjective, it describes a property of a body or material to manifest adherence, to stick, or to remain tightly joined to another layer or support.
- Hollowed — Characterized by many depressions, relief irregularities, or pronounced cavities; a terrain, landform, or waterbed featuring a succession of deep hollows or ravines. In a structural sense, it describes a rugged surface that drops abruptly into depth, being the opposite of a smooth or flat area.
- Adsorbent — A solid or liquid substance that provides the boundary surface or interface onto which atoms, molecules, or ions of a fluid adhere and accumulate during the adsorption process. Unlike an absorbent, which assimilates particles throughout its bulk volume, an adsorbent operates exclusively as a surface phenomenon driven by residual intermolecular Van der Waals forces or covalent chemical bonds. Adsorbents typically feature high porosity and an extensive specific surface area per unit mass.
- Adsorbate — A fluid substance (gas, liquid, or dissolved solute) whose molecules are attracted, retained, and concentrated as an extremely thin molecular film upon the surface of a solid or liquid substrate (the adsorbent). The adsorbate constitutes the mobile component within the system prior to adhesion and the resulting layer on the interface after the process. Its energetic state and molecular dynamics change radically upon interacting with active sites.
- To adsorb — To attract, bind, and concentrate atoms, molecules, or ions from a fluid phase (gas or liquid) onto the surface or interface of a solid or liquid substrate. This physical or chemical process occurs via residual intermolecular forces or covalent bonds, strictly distinguished from the paronym verb 'to absorb', which entails penetration into the bulk volume. It is a spontaneous, typically exothermic surface-driven phenomenon.
- Adsorbed — Bound and retained upon the surface or interface of a solid or liquid substrate (adsorbent) via intermolecular forces or chemical bonds. The term describes the state of molecules, ions, or atoms originating from a fluid phase that have left the bulk medium to form a thin, concentrated layer at the boundary between two phases.
- Adsorption — The spontaneous physical-chemical phenomenon consisting of the adhesion and concentration of fluid molecules (gas or liquid) onto the surface of a solid or liquid substrate. Unlike absorption (a bulk phenomenon), adsorption is strictly a surface phenomenon driven by the imbalance of intermolecular forces at the adsorbent's boundary layer. It is categorized into physical adsorption (physisorption) and chemical adsorption (chemisorption).
- Adsorption (old var.) — An older or archaic linguistic variant of the noun 'adsorbție' (adsorption), denoting the physical-chemical process whereby molecules, ions, or atoms from a fluid phase are retained and concentrated upon the boundary interface of a solid or liquid substrate. Though common in early 20th-century scientific treatises, it has been modernly superseded by the standard form 'adsorbție'.
- Airbrushing — An artistic technique of painting or decoration based on using the airbrush, through which images are created by the controlled spraying of paint onto various surfaces (canvas, car bodies, walls, skin). It allows obtaining superior photorealistic effects and extremely smooth transitions between hues.
- Ahlfors — The surname of the Finnish mathematician Lars Ahlfors (1907–1996), famous for his fundamental contributions to complex analysis and Riemannian surfaces. He was one of the first two recipients of the Fields Medal in 1936, his name being tightly linked to structural theorems, meromorphic functions, and quasiconformal mappings used in modern geometric topology.
- Brass-plated — Having been covered with a protective or decorative layer of brass through technical processes such as electroplating, electrolytic deposition, or thermal immersion; brass-plated. The term applies to various metallic parts made of iron, steel, or zinc to provide them with enhanced corrosion resistance and a refined aesthetic appearance similar to gold.
- Brass-plate — A regional phonetic variant or secondary technical form for the verb 'a lămi'; the act of coating the surface of an iron, steel, or cast-iron object with a thin and uniform layer of brass, through electrolysis or immersion in molten alloy, in order to provide efficient protection against corrosion and a bright aesthetic appearance.
- Brass-plating — The act of brass-plating and its result; a technological process of coating the surface of a metallic object (usually made of steel, iron, or cast iron) with a thin, uniform, and adherent layer of brass. This treatment is carried out through electrolytic (electroplating) or thermal methods, aiming to protect the base material against corrosion and to give it a distinct aesthetic appearance similar to gold.
- Brass-plated — Having undergone the process of brass-plating; an object, part, or metallic material covered with a protective or decorative layer of brass. In an industrial sense, it describes the final state of accessories or structural elements that have received a yellow-golden finish to improve resistance to wear and atmospheric corrosion.
- Brass-plating — A regional phonetic variant or secondary technical form for 'alămire'; the act of brass-plating and its result, consisting of the crafting or industrial process of coating a steel, iron, or cast-iron object with a thin, uniform layer of brass to ensure anti-corrosive protection and a yellow-golden aesthetic finish. In certain southern dialectal contexts, the term can also represent an action metaphorically derived from the verb 'a lămâi', referring to the souring of a dish.
