Unlike pure metals, most alloys do not have a single melting point, but a melting range in which the material is a mixture of solid and liquid phases.

Unlike precious metals such as gold or platinum, gem diamonds do not trade as a commodity: there is a substantial mark-up in the sale of diamonds, and there is not a very active market for resale of diamonds.

Unlike other metals, cadmium is resistant to corrosion and as a result it is used as a protective layer when deposited on other metals.

Unlike many other metals which form passivating oxide layers, iron oxides occupy more volume than iron metal, and thus iron oxides flake off and expose fresh surfaces for corrosion.

Unlike organic pollutants, heavy metals do not decay and thus pose a different kind of challenge for remediation.

Unlike with differential hardening, there is no distinct boundary between the harder and softer metals, but the change form hard to soft is very gradual, forming a continuum, or " grade " ( gradient ), of hardness.

Unlike ferrous metals — which must be cooled slowly to anneal — copper can be cooled slowly in air or quickly by quenching in water.

Unlike other liquid metals used in this application, such as lithium and mercury, the nonreactivity makes Galinstan a safer material to use.

Unlike the other metals used for this process ( Co, Ni, Ru ), which remain in the metallic state during synthesis, iron catalysts tend to form a number of phases, including various oxides and carbides during the reaction.

Unlike oxy-fuel cutting, the PAC process can be applied to cutting metals which form refractory oxides such as stainless steel, cast iron, aluminum, and other non-ferrous alloys.

Unlike most other types of backsaws, razor saws are also frequently used to cut plastics and soft metals.

Unlike the metals which have a continuum of electronic states, semiconductors possess a void energy region where no energy levels are available to promote recombination of an electron and hole produced by photoactivation in the solid.

Unlike silver, gold is denser than almost all other metals, hence whether something is made of gold is extremely hard to fake.

Unlike bony fish, there is no direct control of the pigment cells by the nervous system, and this results in the colour change taking place more slowly than happens in fish.

Unlike conventional auctions, bids are non-refundable ; if one player bids 65 for psyche and another wins with a bid of 66, then the character with 66 is " superior " to the character with 65 even though there is only one bid difference.

Unlike the other Ainu clans currently living in Russia, there is considerable doubt whether the Nakamura clan of Kamchatka should be identified as Northern Kurils Ainu, Southern Kurils Ainu or as Kamchatka Ainu.

Unlike his translation of the Pastoral Care, Alfred here deals very freely with his original and though the late Dr. G. Schepss showed that many of the additions to the text are to be traced not to Alfred himself, but to the glosses and commentaries which he used, still there is much in the work which is solely Alfred's and highly characteristic of his style.

Unlike France or Germany, there are no special administrative courts of first instance in the Netherlands, but regular courts have an administrative " chamber " which specializes in administrative appeals.

Unlike the NES or Sega Master System, there were few add-on peripherals for the 7800, though its backwards compatibility feature allowed it to be compatible with most Atari 2600 peripherals.

Unlike a conventional tank water heater, the tank is filled only when there is sunlight.

Unlike in soccer, the convention in rugby is for the home side to accommodate its guests when there is a clash of kit.

Unlike binary-addressed computer main memory, there is nothing in a disk drive that influences it to have a total capacity easily expressed using a power of 1024.

Unlike traditional HTML with its large range of character entity references, in XML there are only five predefined character entity references.

Unlike Association Croquet, there are no additional turns for hitting other balls.

Unlike the ETL-based data warehouse, the integrated source data systems and the data warehouse are all integrated since there is no transformation of dimensional or reference data.

Unlike other heliozoans, the microtubules are not in any regular geometric array, there does not appear to be a microtubule organizing center, and there is no distinction between the outer and inner cytoplasm.

Unlike most similar bacteria, enterobacteria generally lack cytochrome C oxidase, although there are exceptions ( e. g. Plesiomonas shigelloides ).

Unlike Maroni, there is no curfew on the Oyapock.

Unlike the feel of pain, which can be fully absent in some human conditions, there is no such condition as congenital absence of fear ( although psychopaths are known to have a much lessened feeling of fear ).

Unlike file sharing systems, there is no need for the uploader to remain on the network after uploading a file or group of files.

Unlike the old code of points, there are two separate scores.

Unlike other Indian schools of philosophy, the Cārvākas argued that there is nothing wrong with sensual indulgence.

Unlike most items, there is no limit on the number of Holy Orbs you may include in an army.

Unlike domain names on the Internet, there is no globally defined list of interwiki prefixes, so owners of a wiki must define a mapping appropriate to their needs.

Unlike in a large number of states, there is no domicile quota in JU as well as for the remaining engineering colleges admitting students through the WBJEE.

Unlike ethanol, methanol is extremely toxic: As little as 10 ml can cause permanent blindness by destruction of the optic nerve and 30 ml ( one fluid ounce ) is potentially fatal.

Unlike beta decay, alpha decay is governed by the interplay between the nuclear force and the electromagnetic force.

Unlike gingerbread (), which is sweetened with honey, Printen are sweetened with sugar.

Unlike mainstream medicine, CAM often lacks or has only limited experimental and clinical study ; however, scientific investigation of CAM is beginning to address this knowledge gap.

Unlike individual groups, the GSO is not self-supporting and maintains a small salaried staff.

Unlike the typical hijackings of land vehicles or ships, skyjacking is not usually committed for robbery or theft.

Unlike McCaffrey's black crystal transceivers, Le Guin's ansibles are not mated pairs: it is possible for an ansible's coordinates to be set to any known location of a receiving ansible.

Unlike Pentecostals, Evangelicals and Fundamentalists generally do not believe that physical healing is within the anointing.

Unlike that, the speed of light is constant and only its direction changes.
