About PTI

About PowderTechnology.info

Powder knowledge structured around
engineering decisions

PowderTechnology.info is an independent technical knowledge platform
for powders, particles, and bulk solids. It connects material behavior,
test methods, troubleshooting, industry context, and process equipment
so readers can move from a practical question to the evidence and decisions that matter.

PTI is built for engineers, QA and QC professionals, R&D, formulators,
laboratory specialists, and others whose work depends on understanding
how powders behave and how processes change them.

Engineering-first structure

PTI starts from the engineering question: what needs to be understood, measured, diagnosed, selected, or verified.

Connected knowledge

Particle behavior, test methods, troubleshooting, process equipment, and industry context are linked rather than treated as separate subjects.

Evidence in context

Sources, standards, methods, and data are interpreted in context, with applicability and limitations kept visible.

Independent editorial model

PTI controls its editorial priorities and technical conclusions. Commercial relationships are identified and kept separate from those decisions.

Why PTI exists

Powder problems cross disciplinary boundaries

A discharge problem can begin with cohesion or moisture, appear in a hopper, require shear-cell data to diagnose, and end as an equipment-design decision. Powder problems rarely belong to one category.

PTI is built to keep those connections visible. We organize scientific literature, standards, laboratory methods, and industrial evidence into decision-oriented technical material that helps readers understand mechanisms, choose measurements, diagnose problems, and define what needs to be verified.

Built for technical work

The platform is designed for people making technical decisions about powders and bulk solids, from laboratory characterization and formulation through handling, processing, equipment selection, scale-up, and quality control.

How PTI is organized

Start from the question you need to answer

PTI is organized as linked technical routes rather than an archive of isolated articles. Enter through an industry, a material behavior, a measurement, an observed problem, or an equipment decision, then move between those routes as the engineering question develops.

Industry applications

Start from the demands of a specific sector and see which powder behaviors, measurements, and process decisions matter.

Particle behavior

Understand how material properties, environment, and process history influence powder behavior.

Test methods

Connect an engineering question to the measurements and characterization methods that can answer it.

Troubleshoot

Start from an observed problem and work toward plausible mechanisms, evidence, and corrective action.

Process & equipment

Compare operating principles, selection criteria, process boundaries, and verification requirements.

Insights & Know-How

Go deeper into current research, methods, process questions, and practical engineering decisions.

How PTI works

Sources, context, and accountable editorial decisions

Editorial responsibility is held by Martijn Daalder, Publisher, and Stéphane Sloots, Editor-in-Chief. PTI distinguishes between what a source shows, what can reasonably be inferred, and what still depends on material, method, or process context. Numerical and technical claims are checked against relevant source material, and current-process content that is materially revised receives human review and approval before publication.

AI tools may support research, comparison, drafting, calculations, language editing, and image production, but AI output is treated as working material rather than evidence. No content is published autonomously.

Editorial independence

Commercial participation, partnerships, and contributor relationships do not determine PTI’s editorial priorities, technical conclusions, recommendations, methodology, or tool outcomes.

Publication & editorial responsibility

The people accountable for the platform and its content

Martijn Daalder

Publisher

Martijn leads publishing, platform development, business development, and industry partnerships. His background combines more than two decades in media and communication with long-term work in powder-technology publishing and technical industry content.

Stéphane Sloots

Editor-in-Chief

Stéphane leads technical editorial quality and contributes expertise across powder technology, materials science, and biochemistry. His role focuses on technical coherence, source quality, and industrial relevance.

Advisory Board

Technical perspective from across powder and particle technology

PTI’s Advisory Board brings together expertise from academia, industry, and specialist laboratory practice. Members contribute technical perspective and strategic guidance from across the powder and particle-technology field. Some of their organizations also work with PTI, reflecting the platform’s close connection with the industry it serves. Editorial leadership remains responsible for PTI’s publication decisions.

Participation & partnerships

Useful industry participation with a clear editorial boundary

PowderTechnology.info does not sell conventional display advertising. Organizations can participate by contributing relevant technical knowledge, supporting useful resources, and building an appropriate presence around the subjects in which they work. Broader partnerships can support the continued development of the platform and its technical resources.

Commercial participation is clearly identified. Participation or partnership does not provide control over PTI’s editorial priorities, technical conclusions, recommendations, methodology, or tool outcomes.

Technical participation

Contribute relevant knowledge, practical context, or technical resources around subjects in which your organization has genuine expertise.

Ongoing participation

Build a consistent presence through an agreed program of useful contributions across the year, with commercial involvement clearly identified.

Platform partnership

Support selected PTI initiatives and resource development through a broader relationship, without editorial rights or influence over technical conclusions.

Explore participation & partnerships

Participation supports visibility through relevance and useful contribution. PTI does not sell editorial conclusions or subscriber access.

Current industry partner

Delft Solids Solutions

Delft Solids Solutions is an industry partner of PowderTechnology.info and contributes specialist laboratory and powder-characterization expertise relevant to the platform. Individuals associated with DSS also serve on PTI’s Advisory Board. These relationships are disclosed openly and do not transfer editorial authority or control over PTI’s technical conclusions.

Contribute to PTI

Technical contributions are considered on editorial merit

PTI welcomes relevant technical contributions, article proposals, corrections, and specialist input. Submitted material is considered on editorial merit and remains subject to PTI’s editorial standards and review process. Commercial participation is neither required for contribution nor a route to guaranteed publication, favorable coverage, or a particular technical conclusion.
