Binder jetting is an additive manufacturing process where a liquid binding agent is selectively deposited onto a powder bed using an inkjet-style print head. The print head moves across a layer of powder, depositing binder droplets to join particles together. The build platform then lowers, a new layer of powder is spread, and the process repeats layer-by-layer.

The three pillars of sustainability, also known as the triple bottom line, is a framework that posits true sustainability requires balancing three main dimensions: environmental, social, and economic. Environmental sustainability focuses on preserving natural resources and ecosystems. Social sustainability addresses equity, community well-being, and human rights. Economic sustainability ensures long-term financial viability without compromising the other two pillars.

The functional unit is a critical concept in LCA that defines the quantified performance of a product system for use as a reference unit. It ensures that comparisons between different systems are made on a fair and equivalent basis. For example, when comparing paint, the functional unit might be 'to protect 1 square meter of wall for 10 years'.

Malcolm Gladwell's "Tipping Point" theory posits that social epidemics are driven by three key types of people: Mavens, who are information specialists; Connectors, who have vast social networks; and Salesmen, who are persuasive communicators. The spread of an idea, product, or message reaches a critical mass or "tipping point" when these three archetypes are effectively engaged.

Cradle-to-Cradle (C2C) is a design philosophy that models human industry on nature's processes. It views materials as "nutrients" circulating in closed-loop systems. The framework distinguishes between two cycles: the biological cycle, for biodegradable materials that can safely return to the soil, and the technical cycle, for materials that are continuously reused or upcycled in industrial processes without losing quality.

Software as a Medical Device (SaMD) is defined as software intended for medical purposes that functions without being part of a hardware medical device. Governed by bodies like the International Medical Device Regulators Forum (IMDRF), SaMD is categorized based on the criticality of the information it provides and the healthcare situation, influencing its regulatory requirements.

Design for the Environment (DfE), also known as ecodesign, is a proactive approach to product and process development that minimizes environmental and human health impacts across the entire product life cycle. It integrates environmental considerations into the earliest design stages, alongside traditional factors like cost and performance, to prevent pollution and conserve resources from the outset.

Viral marketing describes any marketing strategy that encourages individuals to pass on a marketing message to others, creating the potential for exponential growth in the message's exposure and influence. Like viruses, such strategies take advantage of rapid multiplication to explode the message from person to person. It is a form of amplified word-of-mouth, often facilitated by the internet.

A Carbon Nanotube Field-Effect Transistor (CNTFET) utilizes a single carbon nanotube (CNT) or an array of CNTs as the channel material instead of bulk silicon. Depending on its chirality (the arrangement of its graphene lattice), a CNT can be either metallic or semiconducting, making it a versatile building block for nanoelectronic devices with superior performance potential.

The Peer-to-Peer (P2P) platform model is a technological and business framework that directly connects individuals to transact with each other, bypassing traditional intermediaries. In the sharing economy, these platforms facilitate the exchange of goods, services, or capital. They typically provide the underlying infrastructure, including search functionalities, payment processing systems, and crucial reputation and trust-building mechanisms.

A fundamental distinction in word-of-mouth marketing (WOMM) is between "organic" and "amplified" WOM. Organic WOM occurs naturally when customers become advocates simply because they are happy with a product and have a natural desire to share their support. Amplified WOM occurs when marketers launch campaigns designed to encourage or accelerate WOM, such as through influencer outreach or referral programs.

The Net Promoter Score (NPS) is a widely used market research metric that measures customer loyalty and their willingness to engage in word-of-mouth marketing. It is based on a single survey question: "How likely is it that you would recommend our company/product/service to a friend or colleague?" The score is calculated as the percentage of "Promoters" minus the percentage of "Detractors."

The Unique Device Identification (UDI) system is a global standard for marking and identifying medical devices throughout their lifecycle. Mandated by regulators like the US FDA, a UDI consists of a device identifier (DI) for the specific model and a production identifier (PI) for batch, serial number, or expiration date. It enhances traceability, post-market surveillance, and patient safety.
