A tin based perovskite solar cell is a special type of perovskite solar cell, where the lead is substituted by tin.
 It has a tin-based perovskite structure (ASnX), where 'A' is a 1+ cation and 'X' is a monovalent halogen anion.
 The maximum solar cell efficiency reported was 6.4% for methylammonium tin iodide (CHNHSnI), 5.73% for CHNHSnIBr, 4.8% for formamidinium tin iodide (FASnI), and 2.02% for CsSnI.
 The methylammonium tin iodide (CHNHSnI) has a band gap of 1.2-1.3 eV.
The tin whistle, also called the penny whistle, English flageolet, Scottish penny whistle, tin flageolet, Irish whistle, Belfast Hornpipe, feadóg stáin (or simply feadóg) and Clarke London Flageolet is a simple, six-holed woodwind instrument.
 It is a type of fipple flute, putting it in the same class as the recorder, Native American flute, and other woodwind instruments that meet such criteria.
 A tin whistle player is called a tin whistler or simply a whistler.
 The tin whistle is closely associated with Celtic music.
A nibbler, or nibblers, is a tool for cutting sheet metal with minimal distortion.
 One type operates much like a punch and die, with a blade that moves in a linear fashion against a fixed die, removing small bits of metal and leaving a kerf approximately 6 mm wide.
 Another type operates similar to tin snips, but shears the sheet along two parallel tracks 3–6 mm apart, rolling up the waste in a tight spiral as it cuts.
 Nibblers may be manual (hand operated) or powered.
Die Macher is a strategy board game designed by Karl-Heinz Schmiel of Germany.
 The game is based on the German electoral system and each player takes the role of one of five political parties (in the 2006 edition, the CDU/CSU, FDP, SPD, Greens, and Die Linke).
 Parties score points based on seats won in seven state "(Land)" elections, the size of their national party base, the amount to which they control the national media, and how well their party platform aligns with national opinion.
Linux Spike Trojan malware, more widely known as MrBlack, is a type of malware that infects routers, and eventually spreads to other routers.
 Incapsula, an internet security firm, first saw this malware in December 2014.
 This tool is prone to attack devices that still use the default credentials.
 A "bot" is a type of malware that allows an attacker to take control over an affected computer.
 Also known as “Web robots,” bots are usually part of a network of infected machines, known as a “botnet,” which is typically made up of victim machines that stretch across the globe.
In video games, a bot is a type of AI expert system software that plays a video game in the place of a human.
 Bots are used in a variety of video game genres for a variety of tasks: a bot written for a first-person shooter (FPS) works very differently from one written for a massively multiplayer online role-playing game (MMORPG).
 The former may include analysis of the map and even basic strategy; the latter may be used to automate a repetitive and tedious task like farming.
The double cylinder, No 8 and No 9 hand grenades, also known as the "jam tin", is a type of improvised explosive device used by the British and Commonwealth forces, notably the Australian and New Zealand armies in World War I.
 The jam tin, or bully beef tin, was one of many grenades designed by ANZACS in the early part of the First World War in response to lack of equipment suited to trench warfare.
Craniopagus parasiticus is an extremely rare type of parasitic twinning occurring in about 4 to 6 of 10,000,000 births.
 In craniopagus parasiticus, a parasitic twin head with an undeveloped body is attached to the head of a developed twin.
 Fewer than a dozen cases of this type of conjoined twin have been documented in the literature.
 Most infants with this condition are stillborn, or die shortly after birth.
Twin Tin Bots is a 2014 board game designed by Philippe Keyaerts and published by Flatlined Games.
Bots!!
 is a massively multiplayer online game (MMO) created by Acclaim Games as the company's launch title and most popular game, with the theme of robots fighting against computer viruses.
 Players choose from one of three basic BOTS and level up their character through gameplay and buying items with virtual credits called gigas.
 Three game modes exist for the game: Sector Battle, Player versus Player, and Base Battle.
 A Korean version of the game, called BOUT!!
 (Bots Of Unlimited Transformation), also existed and was nearly identical, but received new updates earlier than the American version.
 BOUT!!
 was intended to be originally released on Xbox, but ended up being solely released on PC.
