[Tex/LaTex] Suppress “In:” biblatex

Question

How do I suppress the "In: " before the journaltitle? Like so:

In: Journal of Applied Physics

Answer 1

Insert after loading the package biblatex:

\renewbibmacro{in:}{}

or if you need it only for an entry of type @article (can easily extended to other entry types -- see below):

[...]
\usepackage{biblatex}
\renewbibmacro{in:}{%
  \ifentrytype{article}{}{\printtext{\bibstring{in}\intitlepunct}}}
[...]

If you need it for more entry types use:

\renewbibmacro{in:}{%
  \ifboolexpr{%
     test {\ifentrytype{article}}%
     or
     test {\ifentrytype{inproceedings}}%
  }{}{\printtext{\bibstring{in}\intitlepunct}}%
}
